only in the more glabrous branchlets, leaves and bracts, which are a little broader 
toward the base. The gland is the same in both. Only the c? sex is known. 
There may be other forms of S. gracilistyla Miquel or hybrids of it with different 
species. I mention a 9 specimen of Wilson's from Hondo: slopes of Fuji-san, 
abundant, above 800 m., May 8, 1914, bush 1.8-3.6 m. tall, in which the ovaries 
have a distinct pedicel nearly as long as the gland; the style is only half as long as the 
ovary, and the bracts are very acute and black in the upper part. The leaves are 
bad half grown and are entire, with a pubescence very much like that of the typical 
orm,

I place S. Pierotii Miquel in this section and keep separate sect. Caesiae (see p. 
173). Probably also such species as S. myrtillacea Andersson and S. Bockii Seemen 
and their relatives should be referred to distinct sections.

So far as I can judge mainly from plants cultivated in the Arnold Arboretum it is 
8 good species, easily iistingulihed pee S. purpurea Linnaeus and S. Miyabeana 
en. The mature leaves are broadest below the middle, and their serration is 
ne (5-6 teeth in 1 em.) than in S. Miyabeana Seemen, where the leaves are 
roadest at or above the middle and have a coarser serration (about 3 teeth in 1 
= 2 - The young twigs of S. Pierotii are pubescent, and often glabrous and yellow
