146 WILSON EXPEDITION TO CHINA 
DEUTZIA Thunb. 
Determined by ALFRED REHDER. 
After the publication of my Synopsis of the Chinese Deutzias (see p. 15-25) I 
had the opportunity of examining the material of this genus in the Herbarium of 
the Muséum d’ Histoire Naturelle at Paris, where I found several undescribed 
species; and a further examination of our unnamed specimens of the Henry col- 
lection resulted in bringing to light several Deutzias, three of which proved to be 
undescribed. The descriptions of these new species and varieties are published 
here as a supplement to my Synopsis of this genus. 
7. Deutzia pilosa Rehder. See p. 18. 
Deutzia pilosa, var. ochrophloeos Rehder, n. var. 
A typo recedit pilis simplicibus v. fasciculatis patentibus ramulorum inflores- - 
centiaeque brevioribus et pallidioribus flavidis, folis paullo longius petiolatis 
densius pubescentibus supra pilis plerumque 5-radiatis subtus plerumque 6-radiatis, 
rarius 7-radiatis conspersis, corymbis plurifloris, dentibus staminum exteriorum 
antheram non superantibus. 
Kwei-chau: Kwei-yang, “mont du Collége à la cascade," May 18, 1898, E. 
Bodinier (No. 2216, in Herb. Mus. Paris). 
This variety differs from the type chiefly in the shorter and paler yellowish 
pubescence, in the hairs of the lower surface having generally 6 rays and in the 
larger inflorescence. No. 2216 is represented in the Herb. Mus. Paris by two 
specimens, one having broader ovate leaves, the largest being 6 cm. long and 4 
em. broad, the other having smaller ovate-oblong leaves.
