546. Boltonia different from our asteroides, which has fol. obtusiuscula integr —
besides asteroides we have 2 much alike both have acum.
margine den-
ticulum pedunculus foliosos but one has squamas calicis lanc. the other obcordatas
or obovatas. Yours is the middle one probably glossifolia, the third if
really distinct might be namedaffinis. The dried specimen of the last shows
nothing of , glaucous hue.
547. Is not this Silphium pumilum Mich. elongata Willd. as 464
in the collection of plants you had gathered on your journey to Lancaster
548. Quercus falcata Mich. elongata Willd. as 464
549. Spartina (Trachynotis M) polystachia [polystachya] — cynosuroides Schreber
550. Specimen imperfect is it a new Ludwigia or Oldenlandia?
551. Juncus NS. biflorus might mislead to conceive a small plant like biglumis
it comes nearest to marginatus.
Juncus is a very difficult genus and deserves close observation. Unluckily
I am in want of specimens from abroad and some of your specimens were im-
perfect — 219 acutus? 273 tenuis L. bicornis? Strong varieties 274 crassifolius M. 276 mar-
ginatus? or 551 ?, 369 setaceus Wild filiformis Mich. 468 J. [Juncus] bufonius to 488 A. [Andropogon] bicornus
varietas spicata.
552. Oenothera cannot be hybrida Mich which according to his description comes
near to fruticosa — Your plant has Siliqua sessilis and belongs to the nu-
merous varieties or cospecies of biennis and muricata and grandiflora Ait.
553. nb a very curious diadelphous plant different from any I know the puncta
bring it near to Psoralea and Dalea but legumen is diffent. I wish very
much to see it with riper seeds vessels. Any further information will be extremely
wellcome. Where did you find it?
X with out number a Sesbania — is it the same with the long seed vessel n. 71?
I had one in my garden which flowered with out bringing seed caule 6-10 ped.
florib. lat. from the Mississippi — I found none nearer then Sesbania picta Cavan.
I had another which was also killed by the frost flor. purpur. by the seed vessel
it seemed to be Aeschynomene platycarpa — large wide pod but only 2 seeds —
this came from Washita.
554. exactly our Pensylvanian Eupatorium hyssopifolium growing on high and
dry ridges, when cultivated in good ground the lower leaves are lineari lanc
serr. I think therefore both are the same plant
555. Xanthium spinosum. I had it also from Columbia U.S. it perfects but very
seldom seeds with us.
556. No Smilax which I have seen comes nearer to Catesby? Figure of Sm. tamno-
ides then this. But I think I have seen the same leaves on a plant of the
Smilax hastata Willd, the bona nox Mich. Can it be a variety of hastata?
If you can spare a little time pray inform me what is the real Can-
tac of the Indians? Bartram took it for the Smilax figured by Sloane
and cited by Linnaeus as Pseudochina. This figure agrees exactly with a
plant growing in the Jersies fol. lanc. coriaceis — which I sent twice to D
Smith, once he returned it as S. laurifolia and once as Sarsaparilla L.
How many real species of Smilax have you found? Has not Michaux
too few and Walter too many?
557. New to me and very curious. The habit of a Herniaria. I wish to see more
nb of the plant, my specimen being very small. No known genus agrees exactly
I have marked it untill better informed as ?Pyxidanthera spatulata, nearly
allied to Diapensia.]
How many new genera and species may still be discovered if real botanists
begin to look and look again for plants. Our common collectors look for
ornamental plants and shrubs and so a great number of other plants are
overlooked.
My Elliottia I can not find in any new catalogue and I have nothing
more of it since you gave me the first specimen. Have you seen it
again and how have you found the fruit?
Mr. Hamilton has began the printing of my Catalogue but goes on very slow-
ly about 1/2 sheet every month. I have thought of adding the cryptogamous
plants immediately as far as I am able to do it. Let others do the same then
we may get by addition a catalogue of the whole.

The packet of Mr. Swarz has at last arrived — it has added a little to
my collection, some grasses from Europe and the West Indies one or two Filices
and a number of Jungermanniae.

I am anxious to hear whether D. Baldwin has returned safely to Savanna
and delivered to Mr. Oemler his Algae? Nothing would please me better then
to receive more southern plants but I am afraid sea intercourse is
stopped — How I long to send you some of your desiderata! But

we can not force it. We will have the better time to consider the proper
names of our plants hitherto exchanged. The death of Willdenow has been
a great loss to American botany. He had been at Paris and had seen
Michaux's herbarium and would have given the best explanation. But he
is gone. Whether he has published the continuation of the cryptogamous plants —
I do not know, I have seen only the Filices; who will finish the species I do
likewise not know, perhaps Schrader in Göttingen or Persoon. In either case
the Pensylvania musci and fungi will be described. I have sent to Schrader very near
all the mosses and lichens, to Persoon all our smaller Fungi which can be sent.
Have you found any new N American plants in the 2 and 3 volumes of Hort. Kewen-
sis? I have only seen the first volume and do not intend to get the rest except
they have a greater number of our plants.
Walter pleases me every day better and I think his Flora should be reprinted
with additions. By joining Walter and Clayton with Michaux our American
flora will be respectable.
Mr. Oemler sent me an imperfect specimen of a red flowering Collinsonia from
Savanna, is this praecox or serotina Walter?
The Ludwigia glandulosa in Walter I have reconsidered — am I right when I take
his [ L. glandulosa for your N 395. (microcarpa Mich. not exactly)
L. apetala for Isnardia palustris L.
L. alternifolia for 396. or has he names this ramosissima macro
carpa Mich.
L. linearis " " N. 467 angustifolia Mich
L. decurrens " " N. 108 jussiaeoides M.
L. pilosa " " N. 525. not in ich.
L arcuata " " pedunculosa Mich.
L. rudis is for hirsuta Willd. mollis Mich n. 456
L. suffruticosa for capitata M. ]
I have with out doubt tired you already with my long letter, have patience
with an old friend who forgets himself and can find no end when he is
in spirit with a man whom he esteems, and if you please let me have
soon
a friendly and long letter in return. I remain with unchangable respect
Sir
Your most obedient servant
and sincere friend
