SAXIFRAGACEAE. — DEUTZIA 9 
Western Szech’uan: Chin-ting-shan, thickets, alt. 1200-1500 m., 
May 25, 1908 (No. 2895). 
Differs from the type chiefly in its elongated filaments much exceeding the 
anthers as well in the interior as in the exterior stamens, in the smaller cymes and 
in the green only sparingly stellate-pubescent under side of the leaves. This may 
be a distinct species, if the characters should prove to be constant, but as the ma- 
terial at hand is meagre and does not seem of quite normal development, it may be 
referred provisionally to D. setchuenensis as a variety.

Western Hupeh: Fang Hsien, thickets, alt. 900-1500 m., June 
1910 (No. 4486). — Originally introduced into cultivation from east- 
ern Szech'uan. 
Differs from the type chiefly in the denser more or less heteromorphous pu- 
bescence of the leaves and the many-flowered inflorescence with the pedicels as 
long orshorter than the calyx. Deutzia corymbiflora erecta Lemoine differs slightly 
in its more ascending branchlets, smaller inflorescence and narrower leaves with 
Sometimes nearly homomorphous pubescence. The Deutzia figured by Burvenich 
(in Rev. Hort. Belg. XXVII. 157, t.) as D. corymbiflora does not belong here, but is 
apparently D. purpurascens (Franchet) Rehder or one of its hybrids. 
Deutzia coriacea Rehder, n. sp. 
Frutex metralis ramulis annotinis cinereo-fuscis peridermate tarde 
decorticante, hornotinis fusco-flavidis glabris. Gemmae parvae perulis 
4 exterioribus stellato-pilosis. Folia coriacea partim per secundum 
annum persistentia, ovata, acuminata, basi rotundata v. late cuneata, 
spinoso-dentata, 3-5.5 em. longa et 2-3 em. lata, supra glaberrima, 
nitida, flavido-viridia, subtus pallide viridia, pilis minutis, 5—7-radiatis 
conspersa, utrinsecus 4-6-costata; petioli purpurascentes, glabri, 
5-7 mm. longi. Cymae e gemmis lateralibus et terminalibus aphyllis 
orientes, peduneulo 2-5 mm. longo, rarius longiori insidentes, 5-9- 
florae; flores desiderantur. Capsulae breviter pedicellatae, ovoideo- 
hemisphericae leviter costatae, cirea 4 mm. longae, pube homomorpha 
stellato vestitae; calycis dentes capsula dimidio breviores, late triangu- 
lares, erecti v. leviter ineurvi ; Styli 3, cirea 2 mm. longi, persistentes.

„Deutzia coriacea is a very striking species with its coriaceous Justrous almost 
Spiny foliage; it is most nearly related to D. Fargesii Franchet, which is easily dis-
