26 WEST AMERICAN OAKS. 



Habitat. The type above described is one of the less common trees of the Island 

 of Santa Cruz, off the southern coast of California. I know not of its occurrence else- 

 where, but expect it will be found upon the adjacent mainland. The few individuals seen 

 by me on the island were growing upon stream-banks, in good soil, were shapely trees, 

 apparently in healthy and vigorous condition, but bearing little fruit or none. 



Along with this I place a similar small tree which is no rarity along stream-banks in 

 the southern part of the State. I may name it var. elegantula of the present species. Its 

 leaves are not spatulate, but lance-oblong in outline, and are coarsely and sharply toothed 

 or lobed from base to apex. This species might pass for an arborescent Q. dumosa were it 

 not deciduous. There are specimens of it in the herbarium of the California Academy, 

 collected by myself in Temecula Cafion, San Diego County, 1885 ; others are there ob- 

 tained by Mrs Curran, iu Kern County, a year later, I think.
