THE NEVADA WILD ALMOND # 
The wild almond (Pis. XI and XII, figs. 1 and 2), the most striking 
of all the dry-fruited members of the plum family occurring in the 
United States, was first described by Asa Gray from specimens sent him 
by Dr. C. E. Anderson, collected near Carson, Nev., 1863-1866, and was 
named in honor of Dr. Anderson. 
From field notes and abundant herbarium material collected by the 
writer in person or supplied by Mr. E. W. Hudson, important characters 
heretofore unnoted are brought out and this species is redescribed as 
follows: 
Primus andersonii Gray.

A spiny, much-branched, interlocking shrub 1 or 2 meters high, or, rarely, more 
smooth, erect, and treelike, reaching 3 meters or over; bark of young branches grayish 
green to reddish or yellowish brown, glabrous, on older wood breaking into coarse, 
dark-gray scales. The leaves are convolute in the bud, broadly or narrowly spatulate, 
with rounded or acute apex and short petiole, finely serrulate or entire, often with a 
pair of small glands near the base, 1 to 4 cm. long; yellowish or grayish green, leathery, 
glabrous, or faintly pilose at the base; stomates present in the upper epidermis. 
The flowers, appearing with the leaves, are perfect, 1.5 to 2 cm. in diameter, on 
slender glabrous pedicels, 1.5 cm. or less in length, solitary or fascicled; calyx tube 
short, campanulate, leathery, glabrous, or rarely with pedicel and calyx cup puberu- 
lous; lining nectariferous; the lobes triangular with ciliate margins, often persistent 
on mature fruit; petals from pale to deep-rose color, or rarely white, oval, 6 to 10 mm. 
long, narrowing abruptly to a short claw; stamens 20 to 30; style equal to or longer than 
the stamens; glabrous or only the lower one-fourth hairy; ovary pubescent. 
Fruit roundish or obliquely unsymmetrical, compressed, often with a marked 
winglike ventral expansion, abruptly rounded to an apiculate apex; base distinctly
