BOTANY. 155 
Datura Тномавп, Torr. Bot. Pacific R. Road Rep. 5, р 362. Borders of the Colorado, near 
Fort Yuma; Schott. Mr. Thurber collected at Coratlitas in Chihuahua, 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. 
NICOTIANA PANDURATA, Dunal, 1. c. p. 569.  Alluvions of the lower Rio Grande, Western 
Texas, and in the Mexican States on the west. Not very distinct from N. Roemeriana, Scheele. 
No. 630 and 3000 Berlandier's Coll. (from Matamoras) we think should be referred here.

NIEREMBERGIA (LEPTOGLOssIS) VISCOSA (n. sp.): viscoso-pubescens ; foliis elliptis-oblongis acutius- 
culis basi angustatis, inferioribus longiuscule petiolatis; floribus subaxillaribus; pedicellis 
calyce infundibuliformi-campanulata subeequalibus ; calycis laciniis oblongis acutis tubo dimidio 
brevioribus ; tubo corolls elongato gracili apice gibboso.—Rocky hills, mouth of the Pecos, and 
on Devil's river, western 'l'exas; Bigelow. (No. 535, WrigM.) 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 gibbous 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 oblong, a little curved, strongly corrugated transversely and 
somewhat spirally. Embryo moderately curved. 
WITHANIA P SORDIDA, Dunal, 1. с., p. 456. Western Texas from New Mexico to the lower 
Rio Grande ; near Monterey, Neuvo Leon; Dr. Edwards. Balson de Mapini; Gregg. (Nos. 
531, 532, 533, 1596, and 1598, the last a broad leaved form, Wright. Хо. 616, Fendler, N. — 
Mex.) Perennial; villous pubescent, the pubescence partly glandular. Leaves 1-14 inch 
long. Pedicels 6-10 lines long. Calyx broadly campanulate, villous; corrolla 6 lines in 
diameter, dull yellow. Fruit the size of a large pea. 
WITHANIA? Coronorus. Solanum Coronopus, Dun. in DC Prodr. 13, pars 1 р. 64. Along the Rio 
Grande and its tributaries, from El Paso to Laredo, April—July. (Nos. 534, 1593, and 1594, 
- Wright. Мов. 14 and 480, Coll. 1846, and 484, Coll. 1847-8, Lindheim. No. 675, Fendl., N. 
| Mex. Nos. 666 and 3023, Berlandier. No. 1252, Coult. Mex.) Root 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 аге 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 doubttully to Withania. The calyx increases with the fruit,
