 p. 293. Banks of Comale Creek. August, September. 



(592.) Tephrosia Lindheimeri (sp. nov.) : caule pros- 

 trate- nunc adscendente flexuoso ramoso pube brevi tomentu- 

 loso; foliolis 7-13 late obovatis cuneatisve ssepe retusis mu- 

 cronulatis subtus prsesertim 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. Psoralea cuspidata, Pursh. Fl. 2, p. 741 ; Torr. fy 

 Gr. Fl. 1, p. 688. P. cryptocarpa, Torr. fy Gr. 1. c. p. 301. 

 P. Roemeriana, Scheele in Linnaa, 21, p. 463. * New Braun- 

 fels ; sparsely on rocky prairies. May, June. " Flower 

 entirely blue." — The caudex or root often bears a globular 

 tuber, as in P. esculcnta, &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 Linnwa, I. c. is evidently I. Anil, L. 

 ,5. poh/phylla, 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.
