and the Rio Grande; Jiine. (957.)— The leaflets are pale and cinercoiis (not 

 bright green) above as well as beneath, otherwise the specimens accord pretty well 

 with Kunth's description of C. pulchella, of which it is probably only a variety. 



C. ANGusTiFOLiA, H. B. K l. c. ; Gmy, l. c. (cum char.). Eocky sides of moun- 

 tains, at the head of the Limpio; June, in flower and fruit. (958.) — Except that 

 the flowers are not so large, our specimens admirably agree with Kunth's dcscrip- 

 tion, especially in the particulars in which they diffbr from the narrow-leaved 

 species described below, The linear and falcate legumes (which were before un- 

 known in the genus) I have already described. Plants raised from seeds taken 

 from these specimens have the earlier leaves broadly oval (7 or 8 lines long) ; the 

 succeeding ones oblong, and finally linear.

 Aug. % (a. 959. /8. 960.) S. Mountain ravines, on the Sonoita, near Deserted Rancho, 

 Sonora; Sept., in fruit. (961.) — The leaves in all the forms are some of them 

 often 4 - 5-foIiolate, the additional leaflets being inserted with the lateral pair, which 

 are separated from the terminal one by a rhachis of 2 or 3 lines in length. The 

 minute, strigose pubescence of the stem is retrorse. Stipules lanceolate-subulate, 

 strigulose, very small. Pedicels 2 or 3 lines long, shortcr than the calyx ; which in 



a. and /5. is 5 or 6 lines long, its upper lobe entire. CoroIIa violet-purple in thc dried 

 specimens. Legume about 2 inches long, 2 lines wide, straight, less compressed 

 than in C. angustifolia, cinereous with the same fine pubescence as the calyx, 10 - 

 14-seeded. Seeds subrotund, with a small hilum, not strophiolate. The root is 

 said to be thickened or somewhat tubcrous, and to penetrate very deeply. — In the 

 glabrous upper surface of the leaves, and in the fine and close pubesccnce of the 

 calyx, this plant agrees with the character of C. intennedia, H. B. K., with which it 

 should be compared, notwithstanding the size and shape of the leaflets, which in 

 C. intermedia are said to be only from 9 to 14 lines long. The straight pod, and 

 the characters furnished by the pubescence, sufficiently distinguish it from C. angus- 



tifolia. 



Peteria scoparia, Grai/^ Pl IVright. p. 50. Stony hills near Smith's Eun and 

 Eagle Springs, between the Limpio and the Rio Grande ; June. Also between 

 Frontera and the Mimbres, New Mexico; July. (962.) — A well-marked, new 

 genus. The flowers are tinged with purple.
