Plant Characteristics:  Erect shrub, 2-4 dm. tall, gray scurfy, spineless; lvs. alternate, lower 10-17 mm. long, 2-4 mm. wide, oblong to lanceolate, some with tooth at leaf base,  petioled, scurfy both sides, upper 6-8 mm. long, 2-3 mm. wide, lanceolate to linear lanceolate, without teeth, petioled, the petiole of upper and lower lvs. 2-4 mm. long; plants both dioecious and monoecious; staminate fls. in dense, naked terminal spikes, pistillate in axillary clusters; fruiting bracts sessile or nearly so, rhombic, 5-8 mm. long, 5-7 mm. wide, inflated but not globose, united on lower half, minutely pitted; seeds light brown.  (my description).

 

Habitat: Victoria and New South Wales, Australia.   Blooms and fruits in winter in California.

 

Name:  Atriplex, the ancient Latin name.  (Munz, Flora So. Calif. 352).  Greek, rhagodes, like grapes. (Jaeger 220).  Possibly referring tot he clusters of fruiting bracts.  (my comment).

 

General:  Found only in Big Canyon where it appears to have been introduced at the time the freshwater pond was built in the early 1980's.  The plant has become common in one section of the canyon.   This plant was unidentified until 2003 even though it has been checked in the keys for Southern Australia, Central Australia, the Soviet Union, Palestine, South Africa and Texas.  It is not listed in Flora Europea.  The bracts are similar to those of A. semibaccata except they are not red in fruit.  One wonders where the people who supply these plants or their seeds, get them.  Also introduced with this Atriplex were Encelia farinosa x californica, Centaurea muricata and probably Nolana acuminata. (my comments).           In 2003, Andy Sanders of the University of California, Riverside, identified this plant as Atriplex rhagodioides, an Australian native.  Further study indicates that A. rhagodioides has been misidentified and should be Atriplex nummularia (Dr. S. Jacobs 10/16/85).
