LEGUMINOS^E. 



(590.) Vicia Leavenworthii, Torr. fy Gr. I. c. W. Texas. 



367. Phaseolus retusds, Benfh. PL Hartw. No. 59, p. 

 11. P. maculatus, Scheele in Linnaa, 21. p. 465. On rocky 

 or gravelly soil in the dry bed of the Cibolo River. June, 

 September. " Prostrate ; the stems often running for twenty 

 feet." In cultivation it is more or less voluble. The leaflets 

 are thicker in texture and more reticulated than those of P. 

 perennis, not acuminate, but obtuse or many of them retuse. 

 They are more dilated at the base than in my specimen of 

 Hartweg's plant, but otherwise, there is little perceptible dif- 

 ference. Mr. Wright met with it all the way to the Rio 

 Grande, and Dr. Wislizenus in Chihuahua. 



f P. diversifolius was found on the Liano ; and Apios 

 tuberosa and Clitoria Mariana on the Pierdenales. 



368. Galactia Texana: procumbens, subvolubilis, cine- 

 reo-tomentosa, trifoliolata ; foliolis ovalibus retusis setaceo- 

 mucronatis supra cinereo-puberulis subtus sericeo-canescenti- 

 bus ; racemis paucifloris folio brevioribus petiolum raro supe- 

 rantibus ; legumine eximie falcato sericeo folia excedentibus. 

 — Lablab Texanus, Scheele in Linnma, 21, p. 467. — New 

 Braunfels. August. Root ligneous. Leaflets 1 to 1| inch 

 long, in appearance intermediate between those of G. mollis 

 and G. canescens, less whitened beneath than in the latter. 

 Flowers little larger than those of G. mollis, with hirsute, more 

 attenuated and longer calyx-lobes. Legumes 2g inches long, 

 linear, strongly falcate, densely silky, 9-10-seeded. I do 

 not observe the muricate-tuberculate sutures mentioned by 

 Scheele. Seeds oval, chestnut-colored, with a brown hilum, 

 not strophiolate. The species is nearest allied to what I take 

 to be G. mollis, Michx. Mr. Scheele, with his usual wisdom, 

 provisionally refers the plant (without fruit) to Lablab !
