184 PlanUt Lindheimeriana. 



dris ; leguminibus linearibus elongatis rectis v. rectiusculis 

 acuminatis lasvibus 10 -20-spermis ; seminibus rhombeo- 

 orbiculatis. — Rocky soil, and on grassy slopes, near New 

 Braunfels. August, chiefly in fruit. Also near Austin, 

 Mr. Charles Wright. — A well marked species, which Scheele 

 has described from some of the rather imperfect fruiting 

 specimens gathered by Lindheimer in 1846, in which the 

 legumes are sometimes only an inch and a half long, and a 

 little falcate. But in better specimens, particularly in those 

 of 1847, the pods are straight, from two to three inches long, 

 often 20-seeded. The seeds are not obovate-elliptical, but 

 roundish-obovate, or somewhat rhombic by mutual pressure. 

 It is distinguished from all the species I am acquainted with 

 by its downy stems and minute gland ; from D. depresses by 

 its pointed pods. — D. depressus, Kunth, is common at Key 

 West and Cape Florida, and occasionally comes from Texas. 

 There, however, a more common species is the allied D. 

 acuminatus, Benth. in Jour. Bot. 4, p. 357, which is readily 

 known by its shorter, falcate, and pointed pods. In culti- 

 vation it is prostrate. D. reticulatus, Bcnth., has also been 

 received from Mr. Wright. 



3S6. D. brachylobus, Benth. Mimoscce, in Jour. Bot. 4. 

 p. 358. D. falcatus, Scheele in Linnaa, 21, p. 455. Wet 

 soil near Comale Creek, &c. May, in flower; August, in 

 fruit. This does not grow in dry, rocky soil, nor the forego- 

 ing in wet places, as is stated by Scheele, who has evidently 

 transposed the tickets of these two plants. 



387. Acacia Rcemeriana, Scheele in Linntea, 21. p. 456. 

 Rocky soil, near San Antonio, and from New Braunfels to 

 the Guadaloupe. April, in flower ; June, in fruit (605). — 

 This would appear to be the Acacia Roemeriana of Scheele, 

 said to have been gathered near Austin by Mr. Romer, except 

 that the flowers are " yellowish-white " (Lindh.) instead of 

 rose-color, and the leaves usually bear three pairs of pinnae. 

 The leaflets, 4 to 5 lines long, are membranaceous in the flow- 

 ering specimens, but firmer in those in fruit. The species be-
