Scientific Name: Atriplex griffithsii Standley
Synonyms: Atriplex lentiformis (Torrey) S. Watson ssp. griffithsii (Standley) Hall & Clements; A. lentiformis var. griffithsii (Standley) L. Benson; A. torreyi S. Watson var. griffithsii (Standley) Brown
Vernacular Name: Griffith's saltbush
R-E-D Code: 1-2-2
Description: Gray-green shrub to 1 m tall, much-branched; leaves short-petiolate or sessile, elliptic-ovate to narrowly oblong, about 1-2 cm long, grayish with a fine scurf; plants unisexual, the flowers in small clusters in more or less profuse terminal panicles; staminate perianth 4- or 5-cleft, minute; pistillate flowers without perianth; fruiting bracts broadly heart-shaped, flat or convex on sides, united at base, 4-5 mm long, 4-6 mm wide. Flowers August and September.
Similar Species: The common four-wing saltbush, A. canescens, is the only other large shrubby saltbush in the area. Its fruiting bracts have four well-developed wings.
Distribution: New Mexico, Luna and Hidalgo counties; southeastern Arizona, Cochise County.
Habitat: Saline playa margins where plants are not submerged for long periods of time.
Remarks: This shrub is common on playa margins within its area of geographic distribution, acting as a seral species in disturbed areas. It is not known whether the species is present in similar habitats in adjacent Mexico. The species was not treated in Martin and Hutchin's, A Flora of New Mexico.
Conservation Considerations: Many Atriplex provide excellent forage in arid lands. There is no information as to the forage value of this species or how it responds to intensive browsing.
