Herbarium and living specimens of this species were obtained by Dr. Rose at San 
Bartolome Bay, Lower California, in 1911 (No. 16188), some of which afterwards flowered 
in cultivation and were used in preparing the above description. The largest plants seen 
by him were up to about 4 dm. high, but the species may reach greater development. 
Dr. Rose also collected this species at Abreojos Point, Lower California, March 16, 
1911 (No. 16249). H is apparently common along the west coast of Lower California, 
usually growing at low elevations and as a rule forming the dominant feature of the 
landscape.
