          can certainly see nothing in our tree to warrant the
 name of nigra.  The fruit is the size of the common
 garden plum, of a bright reddish orange color - and
 is much admired when fully ripe, though it has a
 thick [coniaceous?] skin, which if chewed is rather [acerbic?]
 & astringent. Muhlenberg certainly must have seen the 
 plum; but he, nor no other Botanist that I know of, 
 notices Marshall's description; which is a good one.
 I should be pleased to hear when we may expect to
 see the next member of your Flora; as I shall look
 for it with great interest.  I am not aware that I
 can furnish any thing worthy of your notice for it;
 or I should do so with great pleasure.
 I will however just mention here,
 that in your localities of [Talinum
 aurantifolium?], you may give this, as
 one where it is very abundant, on
 our Serpentine rocks.  Among those yet
 to appear in your work, I may also mention
 the following, as seeming to me most remarkable in
 our vicinity - though perhaps common elsewhere - [viz?]
 [mentha borealis?] - [Pycranthernum muticum,Mx.?] -Buch-
 nera americana - Gerandia auriculata (never found, but once &
 then a fine specimen in 1816) - Cardamine rotundifolia - Arabis
 lyrata - Cordyalis cucullaria - Polygala senega - Crotalaria parviflora-
 Stylosanthis hispida -[ Phaseolus parvulus?] - [Orchis ciliaris?], O. fi-
 boriata - O. tridentata - O. lacera & O. herbiola - Triphora pendula-
 Ostrya virginiana - Populus grandidentata, & P. heterophylla -
    I hope you will not think my long epistles too
 great a bore - for when I get on these topics, nothing
 but the limits of the paper can stop my desultory
 remarks.  It will give me great pleasure to hear from
 you ; & I beg you to accept the [ap..?] of my great report,
 Dr. Jn. Torrey. West Point.           Wm. Darlington
