 stipules linear, ciliolate, 2-3 mm. long ; flowers 2-3 mm. long, 

 axillary, nodding, on filiform finely puberulent peduncles, which 

 are less than 1 cm. long ; bracts on the peduncles slightly below

The type locality is Cape San Lucas, Lower California, from

 in this paper. 



It should be noted here that some of the specimens show two 

 sets of leaves that are quite different in general shape and aspect. 

 The older leaves may be described as thin, membranous, with 

 veins prominent beneath; alternate, ovate-lanceolate to linear- 

 lanceolate, gradually tapering to the apex, more abruptly tapering 

 at the base and decurrent on the petiole, dentate with prominent 

 unequal rather distant teeth, 3-6 cm. long, 1-2 cm. wide, with 

 petiole 0.5-1 cm. long. The younger or later leaves are mostly
