Oxybaphus nyctagineijs, Swcei; Choisy, I. c. Western Texas and New ]\Iexico ; also in the 

 adjoining Mexican States of Chihuahua and Cohahuila, near the Eio Grande. An extremely 

 variable species, as is shown by Dr. Gray in his note below, 



Oxybaphus hirsutus (Siveet; Choisy^ L c) : caule pilis patentibus hispido ; foliis lanceolatis 

 pilosis utriusque angustatis brevipetiolatis margine undulatis ciliatisque; involucris subsolitaris 

 axillaribua ; pedunculis (3-4 linearibus).demum reflexis ; involucris subtrifloris ; fructu hirsuto 

 inter costas corrugato. — Gravelly hills on the Limpio, &c., July; Bigeloio, Wright. Stem 

 12-15 inches high, apparently sometimes assurgent, branching from the base, hispid with 

 short-spreading or reflexed hairs. Leaves 2-2^ inches long, and 1-5 Imes 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 2^ lines long, obovate.

 Texas, New Mexico and Chihuahua ; June — September. 



Oxybaphus coccineus (n. sp.): glaberrimus; caule gracili ramosissimo erecto; foliis linearibus 

 elongatis integerrimis ; panicula terminali laxa ; involucris 3-floris campanulatis 5-fidis, segmentis 

 acutis ; perigonio infundibuliforrai (coccineo) involucro 4-5-ties longiore ; fructu clavato-oblongo 

 profundesulcato. Hill sides, Copper Mines, and on the Mimbres ; Wright, (No. 1723) Thtrher, 

 Bigelow. Highlands between the Nueces and San Pedro ; April — June ; Schott. Santa Cruz 

 Mountains, Sonora ; Capt. E. K. Smith. Eoot ligneous, black and tortuous. Stems 12-18 

 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, o-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. 



Allionia i^'carnata, Linn,; Choisyy I. c. Sandy river-banks and on gravelly hill-sides. 

 Common in New Mexico, western Texas, and Chihuahua, westward to Sonora and California ; 

 flowering from April to September. (No. 1716, Wright.) The 3 leaves of the involucre are
