prairies. Shrubby, many stems form a large ligneous root, 

 one or two feet high. Upper surface of the leaves smooth, 

 and with the petals, destitute of the black glands. "Petals 

 yellow; stamens red." 1 



380. Cassia (Cham^senna) Lindheimeriana (Scheele in 

 Ldnncea, 21. p. 457) : perennis, undique tomento sericeo mol- 

 lissimo albicans ; foliolis 6-S-jugis oblongis utrinque obtnsis 

 basi inaequalibus aristato-mucronatis subtus argenteo-sericeis ; 

 glandula cum stipite tomentoso setiformi inter omnia paria ; 

 stipulis subulatis caducis; racemis folium aequantibus pluri- 

 floris ; legumine lato-lineari complanato parce pilosulo. — 

 Rocky plains and margin of woods, New Braunfels, &c. 

 September. Also found by Mr. Wright from San Marcos to 

 the Rio Grande. — Stems 4 or 5 feet high, from a thick, 

 perennial root, clothed like the petioles, peduncles, stipules, 

 &c. with a dense velvety tomentum. Leaflets from one to 

 nearly two inches in length, silky above, silvery-sericeous 

 beneath, tipped with a very conspicuous mucro. The seti- 

 form gland, with its stipe, between each pair, is a line long. 

 Petals golden yellow with dark veins, half an inch in length. 

 Anthers 7, chocolate-colored ; the three upper stamens rudi- 

 mentary. Legumes 2 inches long, over 2 lines wide. Seeds 

 as in the section. — A species apparently allied to C. argentea 

 and C. mollissima, H. B. K. 



1 The subjoined, very distinct species, comes from the southern borders of Texas. 



Hoffmanseggia CAUDATA (sp. nov.): frutescens ; ramis glaberrimis superne ra- 

 chique foliorum glandulis minimis rariter conspersis ; foliis bipinnatis ; pinnis2-3- 

 jugis abrupte 8- 10-foliolatis, cum impari elongata 24-30-juga; foliolis glaberrimis 

 omnino glandulosis rotundatis oblique subcordatis venosis ; stipulis bracteisque cadu- 

 cis ; racemo sparsifloro; legumine acinaciformi dilatato glanduloso. — Sandy soil, 

 between the Nueces and the. Rio Grande, Texas, Mr. Charles Wright. August, 

 September. — 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, 

 thickish, obscurely mucronulate, subsessile, oblique. Raceme sparsely 6-9-flowered. 

 Legume nearly two inches long and two thirds of an inch wide, flat, reticulated, fur- 

 furaceous-glandular, and roughened with subsessile blackish glands. There are no 

 expanded flowers ; the raceme of one specimen bears unopened flower-buds.
