1917] Fernald,— A Variety of Spiraea latifolia 255 
defined. From the original description of S. salicifolia, y latifolia Ait., 
“racemis paniculatis,” upon which S. latifolia (Ait.) Borkh. was 
based, it is apparent that Aiton was describing the common plant 
with definitely paniculate inflorescences. The two varieties of the 
species may therefore be designated 
SPIRAEA LATIFOLIA, var. typica. S. salicifolia, y latifolia Ait. Hort. 
Kew. ii. 198 (1789). S. latifolia (Ait.) Borkh. Handb. Forstbot. 1871

Var. septentrionalis, n. var., inflorescentiis primariis cylindricis vel 
subcylindricis.
