SAN DIEGO MARIPOSA 
Calochortus weedit Wood 
The San Diego mariposa has a very restricted range, being con- 
fined to the desert regions of San Diego County, California, and adja- 
cent Lower California. It loves the steep, dry slopes of the arroyos, 
whete its long stems wave gracefully in the breezes that blow fit- 
fully over the country. The grasslike leaves often turn brown before 
the flowets have opened. The San Diego mariposa differs from some 
of its Californian relatives in having its flower cups adorned with 
beardlike hairs grouped about the nectar gland at the base of each 
petal. 
The specimen sketched was obtained in the outskirts of San Diego, 
California.
