S. obovata is closely related to S,glabrescens, but differs in the 

 larger leaves, which are densely villous-pubescent above. It re- 



sembles also S. dumosa but its leaves are decidedly glandular- 



atomiferous. The following specimens are referred to it : 



California: Woods on Truckee River, July 17, 1886, Sojme 



(type); Bear Valley, Calaveras County, Aug. 23, 1892, Geo. 



Hansen 2J4. 



Spiraea fissa Lindl. has been improperly understood. By the 



courtesy ofthe Director of the Kew Gardens, the New York Botan- 



ical Garden has received a fine tracing of the type and also some 



F 



fragments. Kuntze's type o{ Schi::onottis argcnteus alpestrisxs now 

 in the herbarium ofthe N. Y. Botanical Garden and there is also a 

 duplicate of Holodistus argenteus bifrons Focke. The former is 

 merely a reduced form and the latter a rather luxuriant one of S, 

 fissa. Neither deserv^es even a varietal rank. Kuntze recognized 

 also a van fissus^ based on Spiraea fissa Lindl. Although he 

 placed the two varieties in different divisions of the key, they can 

 not be separated. The key is not workable, and as he cites no 

 specimens, some of his varieties will remain unknown. The van 

 alpestris is the only one represented in his herbarium. 



6', vebttina is a closely related species, which has been con- 



fused with it and with 5. argeiitea.
