and flexible leaves narrowed be! nv and by the very slender and thread- 

 like filaments on the margin, cont/asting strikingly from the coarse threads 

 of baccata. The pods are oblong and not pear-shaped and conspicuously 

 fleshy pulpy Avith sweet and edible pulp nearly half an inch thick. The 

 pods are pendent. The flow^er cluster is scarcely peduncled. Flowers not 

 seen. The leaves of both species are bluish, and not apple-green as in 

 Mohavensis. This tree has the same habit of growth as Y. brevifolia and 

 often is 20-30 feet hish.

CALOCHORTUS SPLENDENS X PLUMMERAE 



■i 



At the Bum Devore California. May 20, 1928. Plants about 2 feet 

 high, iT5t'ally a half higher than C. splendens, and usually with strap- 

 sbap-d root leaves as in Plummei-ae. Flowers vary from the size of 

 splenden.s to a half larger, bright pink -purple as in splendens. Glands 

 absent, replaced by a purple smooth spot. Lower half of petal long- 

 wlute-hatry within, as in splendens, and not yellow as in Plummarae. 

 The whole appearance of the plant is that of a robust C. splendens with 

 strap-sIiarK>d loaves, but has onion-like leaves. At first this seemed a 

 valid srecics, but further search showed intergradcs with small glands. 

 S. Plumnierae comes into bloom just before C. splendens goes out, and 

 grows m the same locality with C. splendens. 



Warhir.gtonia filifera. An examination of the flowers of this species 

 m the probable tj-pe locality shows that the perianth is made up of two 

 distmct STts of .3 each, the outer set being cordate or very broadly ovate, 

 and barely 1 mm. long and erect. The inner set has triangular parts 

 which are acute and closely reilexed, white. The stamens have another 

 about 1 mni. long and linear and versatile, and brownish. The pistil 

 seems abortive though present. No female flowers were found, and no 

 fertile fiower^; cither. This accords with my obser^-ations of the var. 

 bonora% where the flowers are often dioecious or monoecious. But I 

 have not .seen fertile flowers so far. 



Eo-lhca edulis. The flowers of this species are greenish white. The 

 outer perianth members are as in Washingtonia. The inner ones are
