174 Plante Lindheimeriane. 
Drummondii, Torr. & Gray, Fl. 1. p. 690, sine descr. E. 
Texana, Scheele in Linnea, 21. p. 462. — Rocky precipices, 
Upper Guadaloupe. August. Also gathered by Mr. Wright. 
“Shrub 4 to 7 feet high." Vexillum barely emarginate. 
Style little curved at the apex. Ovary with two collateral 
ovules. Legume linear and arcuate or sabre-shaped, com- 
pressed, 5 or 6 lines long, sessile, glandular, dotted, with a 
single oblong seed pendulous from near the apex, empty 
below, agreeing with those of E. amorphoides, as described 
by Schauer, and as observed in Mexican specimens of Coul- 
ter's Collection. ‘The foliage is rather smoother, the vexillum 
less notched, and the style less hooked than in the Hartwe- 
gian specimens of E. amorphoides ; but those of Coulter and 
of Dr. Edwards are intermediate ; so that I have no reason to 
think that the Texan plant is a distinct species. 'The tenth 
stamen is scarcely free in either. All the specimens show an 
oval gland near the apex of the style. — A second species, 
however, with a 4-ovulate ovary, gathered by Dr. Wislizenus, 
has been characterized by Dr. Engelmann, as below.! 
T Amorpua rnuTICOsA, Linn. ; var. subglabra; foliolis el- 
lipticis retusis supra nitidis. — On a creek near Fredericks- 
burg. June. — One of the forms of this polymorphous spe- 
cies, nearly the same as the A. nana, Bot. Mag. t. 2112. 
(595.) A. rguTICOsa, Linn.; var. subglabra; foliolis ob- 
longis seu lineari-oblongis. A. Lewisii, Lodd.! Cat. — New 
Braunfels. Like the last, except that the leaflets are narrower 
and seldom .retuse. I know of no constant characters for 
distinguishing ..4. glabra, Desf., A. Caroliniana, Croome, 
1 * E. spinosa (n. sp.): fruticosa; ramis squamosis rachidi spicarum persistente 
lignosa spinosis ; foliis 6-8 jugis; foliolis minutis ovatis acutis adpresse pilosis ; spicis 
een calycis obconico-campanulati dentibus triangularibus obtusis insequali- 
vexillo profunde bilobo; staminibus subdiadelphis; orario 4-ovulato et stylo 
spice uncinato gin — On Lite Encinillas, north of Chihuahua, Dr. Wislizenus; 
r, August and September.— A rough looking, in many respect: ible 
sah, 2- 3 feet ime with black bark. Leaves 4 to 6 or 7 lines long: leaflets 1— 14 
lines long. Spikes an inch long, with a stout persistent rachis ; flowers at first white, 
rose-colored : uppermost (vexillary) filament shortest and almost free, adhering t 
the tube only ata base: style strongly hooked." — Engelm. Mss. — — ^ —
