from a woody root, very slender and wiry, decumbent, somewhat hairy 
(with the characteristic hairs of the order); leaves on short but distinct 
petioles, slightly cordate at base, ovate-oblong, very slightly mucronate, 
pale and veiny beneath, 9-18’ long. Normal flowers with 10 large glands 
on the base of the calyx-lobes; petals clawed, glandular fimbriate above ; 
stamens monodelphous at base only, perfect anthers 3, imperfect (on fila- 
ments about the same length) 2; “fruit of a single carpel, of nearly the same 
form as in A. Hartwegiana, but more even, with rounded and only slightly 
margined sides” (Gray); three or four together terminating filiform pedicels 
on foliaceous or bracted peduncles, or on slender pedicels from the axils of 
the leaves. Abnormal flowers on slender peduncles, which are terminated 
by a pair of bracts 4’ long and half as wide, from between which the 
short pedicel and its flower arise. (627.) Sanoita Valley, Southern Arizona.
