NortH CAROLINA.—Without locality or number, Ashe (distributed as A. 
georgiana Small). 
Frorma.—Lake Co., Eustis, Hitchcock, vii. 94; Nash, no. 261 (see also the 
undetermined forms). 
A. virgata typica is a species witn rather broad ovate or elliptic-ovate leaflets; 
but there are the following southern rorms (from Florida) which differ in smaller, 
more elliptic-lanceolate leaflets with more cuneate base. I cannot say yet 
whether they represent a gooa variety.

n Biltm. Bot. Stud. 1:139. 1902, Boynron describes as a new species A. 
nitens from Waynesboro, Georgia. Unfortunately I have no type specimen at 
hand. It is possible that A. mitens is a good but very local species, distinguished 
by its glossy twigs, its thinner leaflets, and its more falcate nearly glandless 
legumes; but all these characters are rather slight ones. 
I have before me two different specimens which I cannot identify with any 
other form mentioned here; the first probably may belong to A. mitens; the second 
is a very striking form, most resembling A. paniculata (nervis foliolorum subtus 
elevatis), but the leaflets are rather thin and glabrescent. 
TENNESSEE.—Cocke Co., Kearney, no. 641 (also somewhat resembles A. 
glabra). 
FLoripa.—Chattahoochee River, Bush, no. 13. 
13. A. LAEVIGATA Nutt., Torr. et Gray. Fl. N. Am. 1:306. 1838. 
The type was found on the “banks of the Arkansas, near Salt River.”” The 
description given by NurTratt is not clear. He says “leaflets distant, elliptical- 
oblong, attenuated below;” and also “with large distant and very obtuse leaf- 
lets.” Torrey and Gray did not see this species, and it seems to me very difficult 
to clear it up without an original specimen. The interpretation of A. /aevigata 
given by Boynton in SMALt’s Flora (625) is probably not correct; but if it is, 
A. calijornica and A. laevigata would be very nearly allied! 
I myself believe that a specimen collected by an unknown gentleman on the 
banks of the Little Mamelle River, Arkansas, July 1825, which I found in Herb. 
Engelmann under no, 1043, with the determination A. laevigata Nutt., may be 
the true species of NuTTALL. Most of the leaflets are large and broad-elliptical 
with a round or slightly cuneate base. Some leaflets are more ‘‘suborbicularia” 
or more “‘late ovato-lanceolata.”” The apex is rounded and “fere semper leviter 
emarginata.”’ e leaflets are rather thin, but firm and smooth and ‘‘fere 
trima.” The small fruits are the same as those of typical A. texana. 
Another quite glabrous specimen is that which has been collected by E. Hall, 
no. 128, eastern Texas, Creek bank, Houston: foliolis minoribus, ad 3.5 
1.8 magnis. ellipticis, basis subrotundatis vel subcuneatis, apice rotundatis
