3_jQdm j^ diameter, the folds 75-80, deciduously tomentose toward 

 the base beneath, cleft little more than one-third toward the base, 

 not filiferous except for an occasional single filament in the sinuses 

 of some of the folds: peduncles declined, exceeding the leaves; 

 primary divisions 6-8, each bearing 5-10 separated thryses, which 

 are mostly exceeded by their narrow, deciduous, chartaceous bracts; 

 flowers nearly sessile: calyx tubular-campanulate, 3"^^ long, the 

 short rounded lobes lacerate: tube of corolla 3^"^ long, its lobes erect, 

 narrowly lanceolate, 6-7"""^ long: filaments subulate, 3^"^ long, 

 the versatile anthers 4"^"^ long: seeds broadly ovate, 6-7 by 5 

 somewhat rugose on the raphal face. 



Described from cultivated trees growing in San Bernardino and Riverside, 

 California; probably indigenous in northern Lower California. 



This palm is readily distinguished from W, filijera and its varieties by its 

 slender trunk and smaller and less deeply divided leaves, which are without fila- 

 ments and on shorter petioles. It is a tree of rapid growth and has been exten- 

 sively planted in recent years in southern California, under the mistaken name 

 of W. robusta, the true W. rohista being known as IF. filifera. According to the 

 report of a reliable dealer, the seed from which the older trees were grown was 

 procured from indigenous groves in canons, running to the sea, on the coast of 

 Lower California, somewhere between the international boundary and Ensenada. 

 Cultivated trees, which now have been fruiting for a number of years, are the 

 present sources of the commercial seed. Much has been gathered from two 

 noble trees, among the oldest in cultivation, which ornament the lawn of Mn 

 D. W. McLeod, of Riverside.

This species is readily separable from the others by the obtuse 

 juncture of the petiole with the blade. I have seen only young plants, 

 and their leaves are very abundantly filiferous.
