enjoyes his ferriage as he calls it vastly and would prefer to remain on board I suppose, a few weeks longer. Our company is as I hoped and expected, comparatively small, only about 60 or 70 and good many of our fellow travellers prepare to go to Italy, Egypt, Palestine, etc. and many have been before already over Europe. Our ship behaves very well, and almost all day is spent on deck in this delightful weather — tell that to Agassiz who predicted such a pleasant voyage for us.

You see that I have been writing letter which I beg you to send to their destinations.

To Hooker and to Carey I have also written and shall send your sheets of Carices to the latter from South Hampton.

The books I will deliver in Paris if possible myself; I shall make a stay there of a week or so in order to arrange

for the engraving of about half of my plates, the other half will be done in Washington.

I believe I told you that I had finished reading proof the last night in N York, and the printer promised to send the revise to you; an index I have prepared here on board. — The "Herald" will make some alterations necessary, which I will send from Paris both for Emory, Whipple and if for the Boston Journal: for the latter I have already sent you and addition, Cereus roetteri, but I do not know whether I have told you that {Cereus} dasyacanthus {var.} minor must be stricken out, as this minor is the red flowered {Cereus} roetteri; make the same connection in your herbarium. You have that plant in fruit as I myself; but Torrey has flowers and in Washington is a living specimen. And now farewell; my wife and boy send their best regards to Mrs Gray as I of course

which certainly looks very distinct from this European form, but flowers and fruit are the same. I believe I have sent you specimens

{Polygonum} avicularia all our own western plants belong to a pentandous variety — therefore not introduced from Europe, where it is 8 androus.

I can not say, whether dumetorum & scandens are identical — I have sent you different forms, macro pterum microspermum, and microspermum petrum {Polygonum ramosissimum} has a smooth shining fruit

I have sent your notes and specimens about a Rumex which I named {Rumex} angustifolius I believe.

Borya ligustrina Euphorbia — you have or will get my full notes.

Acalypha gracilens add. var: monococca I have sent you specimens: with one seed twice as large as the seeds of the common gracilens

{Acalypha} caroliniana I have found in our streets — no doubt introduced — has disappeared again. — "Croton ellipticus Nutt " {Croton} glandulosus — Illionois, Carya oliviformis Quercus tinctoria Ours is either an intermediate form of {Quercus tinctoria} & {coccinea} or a distinct, new species — the Pennsylvania specimens before me seem distinct. Sparganium 2 species Alismaceae Sisyrinchium bermudiana and an earlier flowering white species, on drier localities, barrems. Trillium recurvatum Allium striatum Hether anthera {Heteranthera} ovalis Commelina agraria

Gray I just sent a letter off for you, but forgot to mention your Cactaceae. I am sorry you have printed that already. Opuntia rafinesquei is certainly a good species; but I must confess that I have for {Opuntia} vulgaris only that single speciman brought by Wislizenus from the Potomac. — That is spineless or has rarely a single stout brownish yellow spine not "a few small spines" — Why do you say: {Opuntia rafinesquei} "probably in Virginia" — It certainly grows in Kentucky, but I do not know any thing of a more eastern locality Raf. himself confounded both species and perhaps probably to {Opuntia} tuna, cultivated in Italy for {Opuntia} vulgaris # {Oxybaphus} nyctagineus grows in Illinois, opposite here. — # or was Millers name: {Opuntia} vulgaris posterior to Rafinesque's?? Rafinesque. ————— Additions to Flora from the neighborhood of St Louis Clematis pitcheri — ({Clematis} viorna I have never seen here) Ranunculus micranthus Trautvetteria palmata Beardstown, Geyer Convolvulus carolinus Southern Illinois Nasturtium sessiliflorum, {Nasturtium} obtusum {Nasturtium} curvisiliqua Draba brachycarpa Viola delphiniifolia Hypericum drummondii (so far only found west of the Mississippi, in Missouri) Anychia capillacea, a good species Sida hispida (so far only west of the Mississippi and destroyed on its original locality — within the present city of St Louis Linum boottii Rhamnus lanceolata Ampelopsis cordata Phaseolus leiospermus
