the Pecos; Aug. Also in tlie collection of 1851. — Slirul) from one to tlirce feet 

 high, erect, much branched. Leaves simple, 3 to 4 or 5 lines long, silvery-canes- 

 cent, like the branchlets, peduncles, and outside of the calyx, with avery fine matted 

 pubescence. Sepals 5, purple inside ; four of them nearly equal, lanceolatc from a 

 broad base, acuminate, about 3 lines long, the fifth smaller and Hnear. The thrce 

 upper petals very small, linear-spatulate, appearing likc sterile filaments. Stamcns 

 wholly distinct, the two intermediate rather shorter. Fruit beset with small and 

 slender prickles, which are glochidiate at the apex only. — Except that thc lcavcs 

 are not villous, this species is scarcely at variance with the imperfect charaetcr of K. 

 pauciflora, DC; but the drawing upon which that species was founded represcnts 

 a low or procumbent plant, much like the K. secundiflora. Specimens just reccivcd 

 in Mr. Wrighfs collection of 1851 appear to show that K. secundiflora and K. 

 lanceolata are hardly specifically distinct. — K. cinerea, Schauer^ with trifoliolate 

 leaves, is also in Coulter's Mexican collection (No. 735), from Zimapan.

• P. sinuatus, NutLj of which I have fine specimens frora Rugers Florida collection, No. 132, is widely 

 different from P, perennis ; but is apparently closely allied to P. pedicellatus, Benfh, The leaflets of 

 some of thelower leaves are rounded, retuse, and entire. 



Phaseolus bilobatus, Engelm. in Wisliz. Mem. K Mex.p. 109, is evidently the same as P. heterophyl- 

 lus, Benth. Fl. Hartio. No. 50, and apparently also of Willdenow, who describes the leaflets as linear- 

 oblong, and the root as perennial (not annual, as De Candolle states) : in Hartweg's specimens it is 

 tuberous.
