Standley — New Trees and Shrubs from Mexico. 133 



Guadalupe Canyon is on the border between Sonora and New Mexico. 

 In the Hora of New Mexico* the writer reported this plant from that 

 State as V. californica (Torr.) Sarg. , upon the basis of Dr. Mearns' pub- 

 lished notes. Upon examination of the specimens, however, it is evident 

 that theSonoran plant is different from that species, which occurs farther 

 west. In V. californica the lower surface of the leaves is covered with a 

 fine, close, persistent, white tomentum, the leaves are much larger, the 

 petioles twice as long or longer, and the inflorescence broad and many- 

 flowered. 



Odostemon longipes Standley, sp. nov. 



Branches dark gray or blackish; leaves 20-30 cm. long, the rachisvery 

 slender, somewhat flexuous, glaucescent, the leaflets usually 11 or 13, dis- 

 tant, sessile or the lowest short-petiolate, the upper ones slightly smaller 

 than the lower, the lowest pair borne 4-5.5 cm. from the base of the 

 rachis; leaflets narrowly oblong, lance-oblong, or ovate-oblong, 3.2-5.5 

 cm. long, 0.8-2 cm. wide, acute or acutish at the base, rounded or obtuse 

 at the apex, mucronulate, entire, subcoriaceous, glabrous, dull, pale 

 green above, glaucescent beneath, the venation prominent and finely 

 reticulate on both surfaces ; flowers racemose, the racemes 15-22 cm. long, 

 long-pedunculate, the rachis very slender, the flowers few, remote, the 

 pedicels slender, glaucescent, 1.5-2 cm. long; fruit subpyriform, about 1 

 cm. long, very glaucous; seeds obovoid, compressed, about 7 mm. long 

 and 3.5 mm. wide, dark brown, dull.

 Ramon, Durango, Mexico, in 1906, by Edward Palmer (no. 103). 



Related to O. chococo (Schlecht. ) fbut in that species the pedicels are 

 usually less than half as long, and the leaflets deep green, very lustrous 

 on the upper surface, and with less prominent venation. The present 

 species is a large shrub or small tree, for a section of the bright yellow 

 wood is 7.5 cm. in diameter. 



Odostemon quinquefolius Standley, sp. nov. 



Large shrub, glabrous throughout; leaves 9-15 cm. long, the rachis 

 stout, the leaflets 5, distant, subequal, sessile, the lowest pair borne 3-4.5 

 cm. from the base of the rachis; leaflets oblong-ovate to ovate-oval, 3-5.3 

 cm. long, 1.5-4 cm. wide, rounded or broadly cuneate at the base, obtuse 

 or acutish at the apex, coarsely dentate, with 7-10 large spreading spine- 

 tipped teeth on each side, coriaceous, green, lustrous, the venation 

 prominent and finely reticulate on both surfaces ; inflorescence racemose, 

 the racemes 7-11 cm. long, long-pedunculate, densely many-flowered, 

 the rachis stout, the pedicels 2-5 mm. long, furnished with 2 small 

 bractlets near the middle, the bracts small, ovate-acuminate; outer sepals 

 small, oval, acute, the inner ones oval, obtuse; stamens bidentate.
