(seq. 4)

I am very much obliged to you for communicating the names and num-
bers of the plants figured in Abbots Insects. I have seen them but only with
half a look at D. Bartons, he did not seem willing to let me have a copy
of the names and numbers, however I put down from the 104, about 50 which
I could remember without remembering the number. I had written twice to Mr.
Oemler for a compleat copy of both, happily, you have anticipated my wishes
and have my best thanks. Amongst those I put down there is but one wanting
the Ammannia humilis, the rest I find in your letter.
We agree almost in every plant 6 is certainly Asclepias tuberosa L not curass [curassavica].
Tilea 11 has on one tree folia pubescentia and argendea 19 Robinia I have seen
a specimen from Kramsch which seems to differ from R [Robinia] pseudoacacia, viscosa and
hispida I named it in MS rosea. Hedysarum 20 is neither Walters nor Willdenows
paniculatum. Glycine 22 can this be tomentosa erecta Mich? the real reticulata Swarz
is caule volubile according to Persoon. Vitis 28 agrees very well with our labrusca
commonly called Foxgrape of which we have many varieties black white, green ber-
ries. Gaura 31. 99. biennis L. angustifolia M. I put down as 2 different species.
41. Vitis vulpina L. however when I sent our Vitis vulpina Smith answered a exactly
vulpina L. probably he took both for one species Viburnum prunifolium 53 here also
2 species are mixed this is not our common prunifolium. Quercus 56 discolor wild
Quercus 59 nana wild. Helianthus 64 divaricatus L. a bad name Anonym. 68 is the
same shrub we have by the name of Lyonia. Willdenow names it in his Enume-
ratio horti regii Berol. Mylocarium ligustrinum. The figure is bad Bartram
in his Travels mentions it p. 31. Seed vessel like Buck wheat. It grows in Georgia
My specimen I had from D Brickell. Smith returned nT. 68 of Abbot as the plant
which he then intended to name Walteriana —
Populus 71, is exactly angulosa Michaux not angulata Willd. and hardly of Aiton
Willdenow names the Poplar cultivated on the streets of Philadelphia (geminis resi-
nosis foliis cordatis margine pubescentibus subtus candicantibus) angulata.
Smith in one of his letters writes of Poplar I know nothing. There is a
miserable uncertainty amongst the Botanists. When Michaux fil. publishes his
figures I expect something certain. How many species of Populus have you?
Hedysarum. 84. Linne had 2 species under one number for marilandicum
84 is cili-
are of Willdenow, the true one is figured by Dillen.
when ever I come to Philadelphia I will try to have a second sight of the figures.

Has Mr. Abbot continued his figures? and is he able to mention any particulars
of his plants? By his vulgar names you may clear many of our doubts we are not as acquainted with those names.

Mr. Lyon I hear is lately returned to this country. He could give a good
deal of information on many of our new especially southern plants which
he exported to England, some are allready in Donns Catalogue. I hope to see
him next May or hear from him by letter although he is very shy
Kin is still alive, he insists that all his Vaccinia are really distinct species
and is rather distinguished that I doubt of it. He complains bitterly that he is
robbed whenever he makes excursions to any distant place, however he intends
another journey to the southwards. I wish great success to him as he is poor
and in difficulties.

Of your dubious plants in Catesby I know none for certain 92 Plumeria rubra is
a Bahama plant 75 Bumelia salicifolia likewise 72 Cypripedium would come nearest
to a caule but the description mentions folia cantina allerna, can it be parviflorum
which I have never seen alive, 52 has the habitus of an Andromeda, 30 a Vir-
giny plant unknown to me Habit of Laurus 28 Phaseolus unknown.
The Pancratium carolinianum Catesb. is not amongst my specimens, mine is Spa-
tha biflora mexicanum Mich.

Donn in his new Edition of Cambridge Plants has a number of N. American new
species which I do not know by their present name. Can you explain them?
Veronica romana, Houstonia divaricata, Pulmonaria mollis, Phlox pyramidalis, suffruticosa
Celastrus bullatus, Viola pygmaea, Ampleopsis hirsuta, Gentiana fimbriata (crinita?)
Viburnum alnifolium, Pancratium rotatum, Prinos lanceolatus, Vaccinium crassifolium
Menzisia globularis, Laurus geniculata, aestivalis (2) Podalyria virginica, Cassia
discolor. Lythrum triflorum. Mespilus prunifolia, Rosa serotina, stricta, Rubus purpureus
Sarracenia adunca, Clematis pensylva [pensylvanica], cylindrica, triternata, Stachys intermedia.
Thymus grandiflorus ♂, Scutellaria pubescens, serrata, Hibiscus incanus, Fumaria for-
mosa, Dolichos miamensis (Glycine umbellata?) Trifolium involucratum, Hypericum pyra-
midatum, elatum, Inula glandulosa, Rudbeckia lobata, Silphium varians
Quercus candida, Juglans minima, hispida, pubescens. Mimosa divaricata, Miamensis
Corypha hystrix, minor. If you have sent some of them pray mention the numbers.
I suppose many of them Mr. Lyon exported.

Since my last I had no opportunity to see anything new. Should I live
and get time to visit my friends at Philadelpha I expect some acquisi-
tions. Mr. Zaccheus Collins continues to be an excellent correspondent, much
like our mutual friend D. Baldwin. If you write to him remember my
best respects. I only wait to hear whether he has arrived at St. Marys, and
then I will write a long letter full of enquiries. He is in an excellent situa-
tion to collect the many species of Fucus and Conferva unknown with us.

With sentiments of great respect and my best wishes for your health and a quick continuation of correspondence I remain
dear Sir
Your most obedient humble servant

As you probably have not the Enumeratio plantarum horti regii botanici Bero-
