p- 293. Banks of Comale Creek. August, September. 
(592.) Tepnrosia LinpuHeimert (sp. nov.): caule pros- 
trato nunc adscendente flexuoso ramoso pube brevi tomentu- 
loso; foliolis 7-13 late obovatis cuneatisve sepe retusis mu- 
cronulatis subtus preesertim incano-sericeis; stipulis brevibus 
subulatis; racemis laxe multifloris; lobis calycis subulatis 
tubo sublongioribus ; legumine pube brevi densa velutino. — 
Muskit prairies, on the Liano. August. (Also gathered by 
Mr. Wright in Western Texas.) Stems rather stout, 3 or 4 
feet long, from a tuberous and ligneous root. Leaflets 8 to 12 
or sometimes 18 lines in length, roundish-obovate or broadly 
cuneiform ; the pairs rather distant on the rachis. Raceme 
7-9 inches long, exceeding the leaves, 20—30-flowered. 
Corolla nearly as large as that of T’. onobrychoides, over half 
an inch broad, purple. 
372. Psoravea cusprpaTa, Pursh. Fl. 2, p. 741; Torr. & 
Gr. Fl. 1, p. 688. P. cryptocarpa, Torr. & Gr. l. c. p. 301. 
P. Reemeriana, Scheele in Linnea, 21, p. 463.1 New Braun- 
fels; sparsely on rocky prairies. May, June. “Flower 
entirely blue.”” — The caudex or root often bears a globular 
tuber, as in P. esculenta, &c. The spikes become oblong or 
cylindrical, and looser in fruit ; the bracts are ovate-oblong or 
obovate, and abruptly cuspidate-acuminate ; the calyx is some- 
what gibbous, and its lower lobe soon elongated; points in 
which the species is not quite correctly described in the Flora. 
The legume is utricular, membranaceous and fragile. 
(593.) PsoraLea cypHocaLyx (sp. nov.): striguloso-sub- 
cinerea, caulibus e caudice lignescente tuberifero erectis sim- 
plicibus; foliis digitatis 3—5-foliolatis; foliolis linearibus 
(majoribus 3-pollicaribus) mucronulatis supra glabratis nigro- 
glandulosis; stipulis subulatis; spicis longiuscule pedunculatis 
1 The Indigofera Lindheimeriana, Scheele in Linnea, I. c. is evidently I. Anil, L. 
8. polyphylla, DC., which I have from Texas by Mr. Wright (although neither Dr. 
Engelmann nor I have received it from Mr. Lindheimer,) and also from South Caro- 
lina, where, according to Mr. Ravenel it occurs not uncommonly in cultivated fields.
