11. P. maculatus, Scheele in Linnea, 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. 
+ P. piversirotius was found on the Liano; and Aptos 
rusEeRosA and Curroria Mariana on the Pierdenales.

reo-tomentosa, trifoliolata; foliolis ovalibus retusis setaceo- 
mucronatis supra cinereo-puberulis subtus sericeo-canescenti-

rantibus ; legumine eximie falcato sericeo folia excedentébum\|€ 
—Lablab Texanus, Scheele in Linnea, 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 2% 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, Micha. Mr. Scheele, with his usual wisdom, 
provisionally refers the plant (without fruit) to Lablab !
