174 Plantcs Lindheimeriance. 



Drummondii, Torr. fy Gray, Fl. 1. p. 690, sine descr. E. 

 Texana, Scheele in Linncea, 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. 1 



f Amorpha fruticosa, 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. fruticosa, 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 squamosis rachidi spicarum persistente 

 lienosa 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 subdiadelplu's; ovario A-oridalo et t.tylo 

 apice uncinate 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 - 1| 

 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.
