WOOTON AND STANDLEY—NEW PLANTS FROM NEW MEXICO. 183 
Padus virens Wooton & Standley, sp. nov. 
A tree 7 meters high or less, with a smooth, reddish brown trunk and 
slender, slightly drooping branches; young branchlets and racemes glabrous; 
leaves ovate, obovate, or oval, 5 or 6 cm. long, acutish or slightly acuminate, 
truncate or usually rounded at the base, thin, bright green, shining, of about 
the same color on both surfaces, finely crenulate-serrate with appressed teeth; 
petioles slender, glabrous, one-third to one-half as long as the blades; leaves 
glabrate in age, when young with a rather abundant tawny tomentum along 
the midvein, some of this persistent at maturity; flowers in slender, loose 
racemes; pedicels slender, 5 or 6 mm. long; hypanthium glabrous, saucer- 
shaped, 5 mm. broad, the lobes triangular, acute; petals 4 mm. long, obovate; 
fruit black, glabrous, globose, 7 or 8 mm. in diameter, sessile in the hypan- 
thium. 
Type in the U. 8S. National Herbarium, no. 560917, collected at Van Pattens

This has passed as P. capuli, a Mexican species, from which our plant 
differs in its broader leaves with the midvein tomentose instead of glabrous. 
In the Organ Mountains this species occurs in abundance in the opening of the 
canyon in which Van Pattens Camp is located. It is known from only this one 
locality in the range, where it grows along with Quercus grisea and Q. ari- 
zonica. Attempts have been made to use the trees as stocks for grafting va- 
rious fruits but they have been unsuccessful. 
The material from the western part of the State may represent a different 
species. It is usually much smaller, only a tall shrub, and its leaves are 
narrower, thicker, not so bright a green, and on shorter petioles. 
Padus pumicea Wooton & Standley, sp. nov. 
Branches stout, numerous, ascending, dark reddish brown, the younger ones 
finely pubescent; petioles mostly one-fifth as long as the blades, sometimes 
longer, finely pubescent, each bearing two large glands; leaf blades obovate or 
oblong, averaging about 45 mm. long, rounded or truncate at the base, acute 
or acuminate, finely serrulate to the base with incurved teeth, bright green 
and glabrous above, finely pubescent and of the same color beneath, often 
becoming glabrate; flowers not seen; racemes stout, few-fruited, finely pubescent 
near the base, glabrous above; pedicels stout, glabrous, much shorter than the 
fruit; seeds globose, 6 or 7 mm. in diameter. 
Type in the U. S. National Herbarium, no. 563903, collected at the “ Craters,” 
Valencia County, July 28, 1906, by E. O. Wooton. 
ADDITIONAL SPECIMENS EXAMINED: Mountains south of Canjilon, August 17, 
1904, Wooton 2706. 
From al our pubescent species this differs in having the leaves of about the 
same color on both surfaces. The fruits, too, are very few and the pedicels 
remarkably short. The branches are very densely furnished with leaves, so 
that in general appearance this is unlike any of our other chokecherries.
