the common Sugar Pine of California, but the cones are not half so long; and, even when young, the scales are strongly reflected, suggesting the Doctor's new name for the species—"Pinus reflexa." It is frequently met with in the deer park referred to, also on a similar plateau on Mount Graham, and is reported also from several other ranges." American Gardeners' Monthly.

NOTES ON VEGETABLES.

PEAS.—The season has been very favourable for these—that is, so far as regards their productiveness and the gathering of them green for cooking; but I fear seed will be scarce and dear, as the weather at the time of ripening set in wet, and prevented crops being harvested in anything like the condition they ought to be. Among the tall kinds the best with us has been Telephone, which is a grand Pea, bearing pods from 5 to 6 inches in length, and these not wind-bags, like those of Superlative, which created such a stir some years back, but every one as full as they can be packed; and the Peas being large, when shelling takes place they soon fill up a dish. It was stated that Telegraph and Telephone are identical; but that is not the case, as they are not only distinct in color, but the last named is much the best Pea of the two, as, eaten either raw or in the cooked state, it is more sweet and tender. Being a strong grower, Telephone should be sown thin, and it is a good plan to have the rows at wide distances, as then they get plenty of air and light on both sides, and crop nearly down to the ground. We grow ours 10 feet apart, and plant a row of Celery between, which enjoys the shade till late in the summer, when it gets full exposure by the Peas being cleared, and there is then plenty of soil for earthing it up, and to get a row of Lettuce or Cabbage between. As yet I have not tried Telephone late, my favourite sorts for this work being British Queen and Ne Plus Ultra, both of which we are now picking, and as they are still full of bloom and vigour they will yield a supply for some time to come. In growing Peas, we always mulch heavily, as it saves labour in watering and keeps the earth cool. J. S.

FRENCH BEANS.—For yielding a suply during the summer and autumn there are none equal to Canadian Wonder, which is a strong grower and a very heavy cropper, bearing pods 8 to 10 inches long, of great width, and these when cooked are remarkably delicate and tender. Unlike most French Beans, that bear only for a short time, Canadian Wonder may be said to be perpetual, as so long as the pods are kept picked off when ready the plants continue to blossom and yield in succession. To afford proper room the rows should be a yard apart, and the Beans 10 inches, and when growing it is a good plan to stick a few brushy twigs by the sides to assist in holding them up, as without support wind and wet often knocks them about. Not only is Canadian Wonder the best late outdoor Bean, but it is a valuable one to grow in pits or frames, planted on a little bottom-heat in March, as towards the end of May the lights may be removed, and the crop the plants yield under such treatment is immense. For pots they are rather too tall and strong, but growth may be restricted by stopping the tops and pinching off some of the leaves—a practice I generally adopt with all winter Beans. F. S.

MARKET POTATOS.—We think that three varieties of Potatos well deserve, after the experience of them this season, where grown in large quantities, to be termed "market Potatos." One of these is Covent Garden Perfection, a second early, of remarkably good quality, and a heavy cropper. In the Northampton district we saw this Potato being dug, and clean, medium-sized tubers in good quantity following a quick growth, dwarf top, and early ripening, was the prevailing characteristic. It is a sort that finds a ready sale in market when dug. It is understood to have come out of the same batch of seedlings as Magnum Bonum. Burbank's Seedling, a white kidney variety, is a sort that finds great favour with the Northamptonshire people. It is an American variety, now rarely found in catalogues. It has a short top, makes a good second early, the produce is good, and the flesh eats dry and well. Our third variety is Vicar of Laleham, a comparatively new sort, that has come out grandly during the summer. It is a variety with a purple skin, and the snowwhite flesh peculiar to this class of Potatos—a heavy cropper, and but little diseased generally. It is in the fullest sense of the word a main crop variety, and, being a good keeper, should be kept till March and April. It is a remarkably fine Potato for mashing. Looker Round.

Orchid Notes.

SPIRANTHES ROMANZOVIANA.—This is not an Orchid which is likely to find favour with lovers of Orchids for their decorative value only; nevertheless, its white and deliciously fragrant flowers render it attractive even from this point of view. The main interest attaching to it consists of its singular geographical distribution. So far as is yet known it is found wild in Europe only in a wet meadow, near Bantry Bay, Co. Cork. But in North America it extends from the Atlantic to the Pacific coast. Did it migrate from America, or was the current in the opposite direction? Did it ever occupy other European territory? These and many such questions this plant suggests for the philosophers to solve if they can. It is a near ally of the Lady's Tresses (Spiranthes autumnalis), now to be found in bloom on our Kentish downs, and elsewhere. Our figure (fig. 86)

was kindly furnished by Mr. Burbidge, under whose care the plant has been successfully cultivated for the last two years in the Botanic Garden of Trinity College, Dublin, the plant having originally been collected by the Professor of Botany, Dr. Percival Wright.

DENDROBIUM CHRYSANTHUM.

I can fully agree with all that Mr. Swan says, respecting the glorious spectacle of such a plant as he brought under notice in your last issue, p. 434. We have here— in the gardens of John Riley, Esq.—at the present time in flower, a specimen of the above with twenty-four flowering growths, several of which are 6 feet long. On one bulb I counted upwards of eighty blooms. The plant is suspended from the roof with Ferns underneath, and I need scarcely add that is a goodly sight to look on. Another Orchid, which is seen to advantage suspended from the roof in close proximity to Ferns, is the chaste Maxillaria venusta, which. in addition to blooming at this time of the year, lasts for several weeks in beauty.

will soon induce disease, especially if the temperature of the house gets low, and the latter practice carried to excess will lead to loss of the foliage at the base of the plants. Where these have to be grown in the same house the Vandas must be placed at the coolest end, as a temperature of 55° to 60° is sufficient to maintain them in perfect health during the winter. One of the best winter Orchids now showing flower is Phaius grandifolius. This should be grown in quantity, as it is one of the few Orchids that will stand being used for room decoration without injury. Where it is used for this purpose it should be prepared by keeping it cooler for a few days before taking it into the room, and while there should be kept drier at the root. Any shy flowering Orchids, such as Schomburgkia tibicinis, Eriopsis biloba, Epidendrum bicornutum, and Cyrtopodiums, must be specially treated at this season of the year, by placing them on dry elevated shelves, maintaining a dry but moderately warm atmosphere around them, and

giving only sufficient water at the roots to keep them from excessive shrivelling. A couple or three months of this treatment will throughly ripen the bulbs, when a good show of flower will follow. J. Roberts, Gunnersbury Park Gardens.

CYPRIPEDIUM INSIGNE PUNCTATUM VIOLACEUM AND C. INSIGNE MAULEI.—Well known as the superior merits of the former variety have always been to the few who have been lucky enough to obtain it true, so many have expressed an opinion that it is nothing but C. insigne Maulei that we are glad to receive from R.P. Percival, Esq., of Birkdale, Southport, a properly authenicated flower of each, taken from strong plants grown on precisely the same conditions. So vastly superior is C. insigne punctatum violaceum to the other variey that we could not refrain from having drawings made of them (figs. 126, 127) in order to set the matter to rest once for all. The variety under notice came to this country as a stray seedling-like plant among some imported Orchids in the year 1855; chance and its own distinct

appearance favoured it, and it was carefully tended. On blooming it amply verified the good opinion formed of it, as the flowers, although borne on a small plant, were of a better shape and more brightly and distinctly marked than those of any other variety. Mr. O'Brien, in whose care it was, jealously nursed and guarded it, but it was not until about the year 1869 that any of it was parted with, and soon the sale of it had to be stopped, as Mr. Dominy (who was one of the first to recognise its merits) and a few more who were waiting for the plant would soon have taken the stock in spite of the rather prohibitory prices. The alternate selling and withholding of the plant according as the stock increased or decreased no doubt has often caused C. Maulei to be passed off for it, as indeed in after years, when C. insigne punctatum violaceum became more plentiful, it may sometimes have found its way into gardens as C. Maulei, and hence the confusion. In small plants the error is not so easily detected, but

when both are grown strong there is scarcely any comparison, particularly in point of size of flower, as a glance at our illustrations will prove. The confusion in the names of this section of C. insigne was further confounded some few years ago by the introduction of the variety called Chantinii, which was nothing but C. insigne Maulei. Although at present C. insigne punctatum violaceum may sometimes be found under that name, there is no doubt that C. insigne punctatum is distinct, and one of the finest of Cyripediums, and Mr. Percival has no cause to regret the forty odd guineas he gave for it.

ODONTOGLOSSUM CRISPUM.—In Messrs. Jackson's collection at Kingston the show of flowers promises to be unusually fine in a week or two. A good many of the most vigorous plants are suspended from the roof of a low span-roofed plant-house, and the flowerspikes are both strong and plentiful. The varieties vary a good deal. We noticed one fine variety with four spikes, and as many as twelve flowers to a spike. This variety is beautifully marked with clear spots.

O. Andersonianum has two branching spikes; this variety is sweet-scented, and is extremely vigorous. Upon the whole the condition of the collection is remarkably satisfactory, and the show of flowers about Christmastide will be worth going a long way to see.

ARPOPHYLLUM GIGANTEUM.—A fine specimen of this rare Orchid is now showing flower in Messrs. Jackson's collection at Kingston. It is the same variety that Mr. Carson used to grow at Nonsuch Park a dozen or fourteen years ago. It has a broader leaf, throws up a much finer spike of flower, and blooms more freely than the small-leaved variety which is commonly cultivated.

LÆLIA AUTUMNALIS ATRO RUBENS.—Go when one will be there is always something interesting to be seen in Messrs. Veitch's Orchid-houses, but a specimen of the above plant having seven flowers upon one spike is a sight that excites one's admiration for these flowers to the highest degree. The flowers are of a purple hue, the labellum being of a rather deeper purple than the sepals and petals, and the throat is white.

SOPHRONITES GRANDIFLORA.—Whoever thinks of cultivating Orchids should make this pretty little plant one of their first purchases. This is the natural season for the plant to flower, and its scarlet blooms are the brightest objects in the Orchid-house at the present season.

SACCOLABIUM BLUMEI.—Messrs. Heath & Son, Exotic Nurseries, College Road, Cheltenham, have kindly forwarded me an unusually grand, and at the same time very curious, inflorescence of this plant. The superior half of the flower has nota single petal, all the flowers being trisepalous, and with a lip not superior to that organ in the petalliferous flowers. It belongs to the Saccolabium macrostachyum, Lindl. Finally, we may learn whether those things are constant or merely varieties of one protean type. H.G. Rchb. f.

DENDROBIUM LEECHIANUM ×.—From Mr. Swan, gr. to W. Leech, Esq., Fallowfield, Manchester, come several blooms of this free-flowering and very desirable hybrid, which was figured and described at p. 256 of our last volume. A spike of four flowers, Mr. Swan informs us, was taken from a bulb that has produced eighteen blossoms, yet which is little more than 1 foot in height. The stock of plants at Oakley consists of eighteen, which are either in bloom or showing flower; and though some of the flowers before us have been open five weeks, they are still bright and fresh. A fine spike of the lovely Calanthe Veitchii superba also came to hand in the same box.

ODONTOGLOSSUM LUTEO-PURPUREUM (Lindl.) RADIATUM (Rchb. f.)—A very charming specimen of this is in flower just now with Messrs. Heath & Son, Exotic Nurseries, College Road, Cheltenham. An old bulb produced twin bulbs, and between the two stands a very fine deeply coloured inflorescence, the flowers being of very strong good texture. It would be interesting to know (of course I got but a sketch and half the inflorescence) whether in all probability the peduncle belongs to one of the bulbs, or whether it is the product of an especial break which would be quite georgeous. H. G. Rchb. f.

PHALÆNOPSIS, with which one house at Rendlesham is mostly occupied, continue to thrive admirably; the house in which they are grown, like the others devoted to Orchid culture at Rendlesham is a low span, constructed so as to give all the light possible, and standing away from everything that could intercept it. The plants are hung well up to the roof, with air on at all times in all weathers; it is admitted freely through openings in the walls at both sides, beneath the side stages. The temperature as near as may be is kept at 70° in the night in summer, and 65° by night during winter. Under such treatment the leaves attain more than ordinary substance, lasting proportionately long. All the kinds seem to do well. Of Phalaenopsis amabilis|P. amabilis]], P. grandiflora, and P. Schilleriana, there are numbers of splendid examples; the largest, P. grandiflora, is just upon 2 feet from point to point of the leaves. The scarce P. Portei has six good leaves, the biggest 9 inches long, by 3 3/4 broad. Cattleya superbiens, hung up in the same house close to the roof, keeps on year after year blooming freely, and gaining additional strength. A couple of plants of Vanda Denisoniana are doing finely.
