OXYBAPHUS NYCTAGINEUS, Sweet; Choisy, l.c. Western Texas and New Mexico; also in the 
adjoining Mexican States of Chihuahua and Cohahuila, near the Rio Grande. An extremely 
variable species, as is shown by Dr. Gray in his note below. 
OXYBAPHUS HIRSUTUS (Sweet; Choisy, 1. c.): caule pilis patentibus hispido ; foliis lanceolatis 
pilosis utriusque angustatis brevipetiolatis margine undulatis ciliatisque ; itvolucris subsolitaris 
axillaribus ; pedunculis (3-4 linearibus) demum reflexis ; involucris subtrifloris ; fructu hirsuto 
inter costas corrugato.—Gravelly hills on the Limpio, &c., July; Bigelow, Wright. Stem 
12-15 inches high, apparently sometimes assurgent, branching from the base, hispid with 
short-spreading ог reflexed hairs. Leaves 2-21 inches long, and 4-5 lines wide in the middle; 
the uppermost ones more undulate than the lower. Peduncles slender, in the axils of the upper 
leaves ; the uppermost ones appearing clustered from the branches being undeveloped. Involucre 
hairy, at length broadly campanulate and reticulate. Flowers all fallen in our specimens. 
Fruit 22 lines long, obovate.

inches high, slender terete, paniculately branched above. Leaves 2-3 inches long, and mostly 
about a line wide, but sometimes 2 lines. Inflorescence a loose cymose panicle. Involucres 
sometimes solitary in upper axils and the pedicels recurved. Perianth about three-fourths of an 
inch long, funnel-form, with a long narrow tube; the limb of a bright crimson, 5-lobed, with 
the lobes notched. Stamens and style exserted. Fruit pubescent, strongly 5-ribbed and slightly 
rugose. This species is almost intermediate between Oxybaphus and Quamoclidion.
