 2. p. 177, is no more than a variety, and scarcely a permanent one, of L. subcarno- 

 sus ; as an inspection of the original specimens shows. The leaflets of both forms 

 are equally succulent, those of the upper leaves often acute, vphile the lower are 

 obtuse or retuse. 



144. SopHORA (Dermatophyllum) speciosa, Benth. in PL Lindh. 2. p. 178. Der- 

 matophyllum speciosum, Scheele in Linncea, 21. p. 459. Western Texas ; common. 



— The specimens gathered by Dr. Gregg, near Monterey, Saltillo, and Parras, with 

 the foliage densely silky-canescent when young, but glabrate or glabrous when old, 

 belong, I suspect, to a mere variety of the Texan plant, and both are probably to be 

 referred to S. secundiflora.

 390; Gray, PI. Fendl. p. 38. New Mexico; coll. of 1851. — The specimens are in 

 fruit, and are the first which have been obtained in this condition. The canescent 

 pods ripen only one seed, either at the base or in the middle, forming an ovate and 

 pointed articulation from 3 to 5 lines long.

 38, Sf PI. Lindh. 2. p. 178. Prairies, east of El Paso, Oct.; in fruit. Also in the 

 collection of 1851. — Some of the stipules show one or two setaceous teeth on each 

 side. The vexillum is often dotted with black glands.* 



146. H. CAUDATA {Gray, PI. Lindh. 2. p. 179): frutescens, glaberrima; stipulis 

 bracteisque cordato-ovatis integris scariosis brevibus deciduis ; petiolis ramulisque 

 glandulis parvis stipitatis rariter muricatis; pinnis 2-3-jugis 8-10-foliolatis cum 

 imparl elongata 24 - 30-foliolata ; foliolis omnino eglandulosis glaberrimis crassius- 

 culis rotundatis oblique subcordatis' venosis; racemo sparsifloro; calycibus sparse 

 glandulosis ; legumine acinaciformi dilatato glabrato glandulis subsessilibus asperato. 



— Sandy soil, between the Rio Grande and Nueces, Texas, Sept. ; principally in 

 fruit. — A foot or more in height. This species is remarkable for its smoothness 

 (some small tack-shaped glands only occurring on the calyx, or a few still minuter 

 ones scattered on the upper part of the branches and the petioles), and for the 

 elongation of the terminal pinna, which is two or three inches in length, and 

 bears many pairs of leaflets ; while the lateral ones are scarcely an inch long. The 

 leaflets are about two lines in length, crowded, thickish, obscurely mucronulate, 

 subsessUe, oblique. Eaceme sparsely 6 - 9-flowered. Legume not stipitate, nearly 

 two inches long and two thirds of an inch wide, flat, reticulated, furfuraceous- 

 glandular, and roughened with subsessile, blackish glands ; the upper suture 

 straight, except the incurved apex. There are no expanded flowers; the raceme 

 of one specimen bears unopened flower-buds. 



* HofTmanseggia melanostlcta (Pomaria melanosticta, Schauer in Linnma, 20. p. 748) was gathered 

 by Gregg at Buena Vista (No. 292), and in a valley near Azufrora (No. 497), Northern Mexico. Al- 

 though allied to H. Jamesii, it is readily distinguished by its larger and fewer leaflets (only 6 or 8 to each 

 pinna), and larger, more muricate, and straighter pods. In one specimen the pod is over an inch and a 

 half long. There are a few sessile black glands on the petioles and branches (as is also the case in H. 

 Jamesii) ; in all other respects it perfectly accords with Schauer's description.
