SAXIFRAGACEAE. — DEUTZIA 149 
2-4 mm. longi, stellato-pilosi. Inflorescentia corymbosa, pluriflora, stellato-pilosa, 
breviter pedunculata; calyx ut pedicelli breves extus dense stellato-pilosus dentibus 
late triangularibus dimidium tubum subaequantibus; petala late oblonga, 6-7 mm. 
longa, alba, extus stellato-pilosa; stamina petalis triente v. fere dimidio breviora, 
filamentis exterioribus apice bidentatis dentibus elongatis acutiusculis antheram 
breviter stipitatam subaequantibus v. paullo superantibus, interioribus lanceolatis 
antheram circa medium affixam gerentibus; styli 3, staminibus paullo breviores, 
3 mm. longi. Capsula matura desideratur. 
Yunnan: Szemao, mountain forests, alt. 1600 m., A. Henry (No. 10786, in 
Herb. Arnold Arboretum.) 
Most nearly related to D. Fargesii Franchet, which differs in its narrower and 
smaller leaves glabrous above and with the hairs beneath having 6—7 rays and in 
the much larger and looser inflorescence. The inflorescence of D. Henryi is borne on 
Short branchlets with undeveloped leaves springing from the end of shoots with 
mature leaves, rarely axillary; this would tend to show that the foliage is persistent 
and that the flowers appear very early in spring, but the whole appearance of foliage 
and inflorescence suggests more a case of abnormal autumnal flowering. 
19b. Deutzia aspera Rehder, n. sp. 
Frutex ramis robustis erectis; ramuli hornotini annotinique verrucis in apice 
pilos stellatos gerentibus dense obsiti ideoque asperi; gemmae perulis lanceolatis 
acuminatis parce stellato-pilosis v. exterioribus fere glabris. Folia decidua, ovato- 
oblonga v. elliptico-ovata, acuminata, basi late cuneata, rarius rotundata, argute 
serrulata, 3-5 cm. longa et 1.5-2 cm. lata, supra obscure viridia, venis venulisque 
impressis et pilis sparsis 4-6-radiatis conspersa, subtus viridia, sparsissime pilis 
8-10-radiatis et papillis crebris praedita, nervis utrinsecus 5-6 subtus elevatis; 
petioli circiter 5 mm. longi, stellato-pilosi. Inflorescentia corymbosa, convexa, 
multiflora, dense verrucosa ut ramuli, in apice ramulorum elongatorum sessilis; 
flores desunt. Capsula pedicello 5-8 mm. longo circa medium bracteas lineari- 
lanceolatas gerenti insidens, subglobosa, pilis stellatis minutis obtecta, circiter 5 
mm. diam., calyce stylisque persistentibus coronata; calycis dentes lanceolatae, 
acuminatae, 2.5 mm. longae; styli plerumque 4, rarius 3, circiter 3 mm. longi. 
Yunnan: south of Red River from Manmei, alt. 2000 m., A. Henry (No. 9475, in 
Herb. Arnold Arboretum). 
Most nearly related to D. discolor Hemsley, but easily distinguished from that 
Species and its allies by the leaves being only sparingly furnished with stellate 
hairs beneath and therefore green, and by the rough branchlets. In its sparingly 
pubescent leaves it resembles D. purpurascens (Franchet) Rehder, which differs 
in its stellate hairs having only 5 to 7 rays.
