S. obovata is closely related to S.glabrcscens, but differs ni the 

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

 sembles also 5. diimosa but its leaves are decidedly glandular- 

 atomiferous. The following specimens are referred to it :

Spiraea fissa Lindl. has been improperly understood. By the 

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

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

 fragments. Kuntze's type of Schizonotiis argenteus alpestris is now 

 in the herbarium of the N. Y. Botanical Garden and there is al.so a 

 duplicate of Holodisais argenteus bifrons Focke. The former is 

 merely a reduced form and the latter a rather luxuriant one of 5. 

 fissa. Neither deserves even a varietal rank. Kuntze recognized 

 also a var. 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 var. 

 alpestris is the only one represented in his herbarium. 



5. vehitina is a closely related species, which has been con- 

 fused with it and with .S". argcntea. It has the habit of S. fissa,
