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

 are cqually succulent, those of the upper leaves often acute, while the lower are 



obtuse or retuse.

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



Thc specimens gathered by Dr. Grcgg, near Monterey, Saltillo, and Parras, with 

 thc foliagc densely silky-canesccnt when young, but glabrate or glabrous when old, 

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



rcferred to S, secundiflora.

 fruit, and arc 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.

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

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 



upper part of the branches and the petioles), and for the 



pinna, which is two or three inches in length, and 

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

* Hoffmanseggla melanosticta (Pomaria melanosticta, Schauer in Li^incea, 20. p. 748) was gathered 

 by Gregg at Bucna Vista (No. 292), and in a valley near Azufrora (No. 497), Northem Mexico. AI- 

 though allied to H. Jamesii, it is rcadily distinguishcd 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 onthe petioles and branches (as is alsothe case in H 

 Jamesu) ; m all other respects it perfectly accords with Schauer's description.
