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. 
+ Amorpua FruTicosa, Linn.; var. subglabra; foliolis el- 
lipticis retusis supra nitidis. — On a creek near F'redericks- 
burg. June.—One of the forms of this polymorphous spe- 
cies, nearly the same as the A. nana, Bot. Mag. t. 2112. 
(595.) A. rruticosa, 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 A. glabra, Desf., A. Caroliniana, Croome, 
1 “E, spinosa (n. sp.): fruticosa; ramis squakgosis rachidi spicarum persistente AA 
lignosa spinosis; foliis 6-8-jugis ; foliolis minutis ovatis acutis adpresse pilosis ; spicis 
paucifloris; calycis obconico-campanulati dentibus triangularibus obtusis insequali- 
bus; vexillo profunde bilobo; staminibus subdiadelphis; ovario 4-ovulato et stylo 
apice uncinato pilosis.— On Lake Encinillas, north of Chihuahua, Dr. Wislizenus ; 
in flower, August and September. — A rough looking, in many respects, remarkable 
shrub, 2-3 feet high, with black bark. Leaves 4 to 6 or 7 lines long: leaflets 1-13 
lines long. Spikes an inch long, with a stout persistent rachis: flowers at first white, 
then rose-colored : uppermost (vexillary) filament shortest and almost free, adhering to 
the tube only at its base: style strongly hooked.” — Engelm. Mss.
