﻿44 Small: Studies in 



Enogonum stellatam and later to R tripoduin. Professor Greene 

 has lately said* that it cannot be associated with E. stellatum, and 

 to prevent the excellent E. tripoduin from becoming a composite 

 species we must describe it as new. Besides the less strict habit 

 and the broader leaves, the glabrous calices serve as a ready means 

 of separation between this species and E. tripodum. 



The original specimens were gathered by Professor Greene on 



ilton, California.

Perennial, matted, densely woolly-tomentose. Stems much 

 branched, woody below: leaves crowded, spatulate, 5-8 mm. long, 

 obtuse, wooly ; blades thick, slightly revolute, narrowed into winged 

 petioles: scapes erect, 1-1.5 cm. long, topped by a head of several 

 involucres: involucres turbinate-companulate, 3-4 mm. high, 

 partially deciduous; segments 5 triangular, green, shorter than 

 the hyaline tube: calices oblong-campanulate, 2.5-3 mm. long, 

 v.llous within and without, the hairs often pointing downward ; 

 segments oblong, obtuse, erect, twice as long as the tube, the 

 inner 3 narrower than the outer: filaments slender, exserted, vil-
