3G2. Borders of the Colorado^ near 



Fort Yuma ; Scliott, Mr. Thurber collected at Corallitas in Chilmaliua, a Datura resembling 

 this species, but with the capsule armed with only a few (about 20) very long and rigid slightly 

 pubescent prickles. Both may be extreme forms of D. Stramonium.

NiEREMBERGiA (Leptoglossis) \T[scosA (n. sp.): viscoso-pubescens ; foliis elliptis-oblongis acutius- 

 culis basi angustatis, inferioribus longiuscule petiolatis ; floribus subaxillaribus ; pedicellis 

 calyce infundibulifornii-campanulata suba3C[ualibu8 ; calycis laciniis oblongis acutis tubo dimidio 

 brevioribus ; tubo corolla? elongato gracili apice gibboso. — Rocky hills, mouth of the Pecbs, and 

 on Devil's river, western Texas; Bigeloiv. (No. 535, Wright.) Root often annual, but some- 

 times, apparently, perennial. Stem 6-10 inches high, usually branching from the root. 



Leaves 8-10 lines long and 2-4 lines wide. Pedicels often extra-axillary, shorter than the 

 leaves. Calyx funnelform-campanulate, about four lines long. Corolla nearly an inch long, 



the very slender tube more than twice the length of the calyx, saccate and somewhat ^yirbous at 

 the throat; limb purple, more than half an inch in diameter, rather unequally 5-lobed, the 

 lobes roundish and entire. Stamens inserted in the succate throat of the corolla and included, 



two of them with short curved filaments and large roundish 2-celled anthers, 2 others with 

 straight filaments and much smaller 1-celled anthers, the 5 stamen a mere abortive filament. 



Ovary ovate acute; style elongated and filiform; stigma dilated and somewhat petaloid, 2-lobed 

 at the base, truncate and 2-lipped at the summit. Capsule much smaller than the fructiferous 

 calyx, roundish ovate. Seeds oblongs a little curved, strongly corrugated transvert-ely and 

 somewhat spirally. Embryo moderately curved.

 Mex.) Perennial ; villous pubescent, the pubescence partly glandular. Leaves 1-1^ inch 

 long. Pedicels 6-10 lines long. Calyx broadly campanulate, villous ; corroUa 6 lines in 



diameter, dull yellow. Fruit the size of a large pea. 



WiTHANiA? CoRONOPUS. Solauum Coronopus, Dun. in DC Prodr. 13, pars 1 p. 64. Along the Kio

Mex. Nos, 666 and 3023, Berlandier. No. 1252, Coult. Mex.) Boot annual? Plant roughish 

 with minute short and thick hairs, which are bifurcate at the summit. Leaves lanceolate, 1-1| 

 inch long, more or less deeply pinnatifid or merely toothed, the upper part often linear and 

 entire. Flowers solitary, on slender pedicels which are at length reflexed. Corolla dull yellow, 

 about 6 lines in diameter. Fruit globose, the size of a large pea, nearly white when mature, 

 about two-thirds covered with the calyx. This plant is certainly a congener of the last, which 

 we have followed Dunal in referring doubtluUy to Withania. The calyx increases with the fruit,
