2-4 mm. longi, stellato-pilosi. Inflorescentia corymbosa, pluriflora, stollato-pilosa, 

 breviter pedunculata; calyx ut pcdicelli 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 branclilets 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 flowermg. 



196. Deutzia aspera Rehdfer, 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 

 eerrulata, 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 cLrciter 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; styU 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 steUate hairs having only 5 to 7 rays. 



22 b. Deutzia calycosa Rehder, n. sp. 



Frutex erectus ramis satis robustis; ramuli hornotini initio sparse stellato-pilosi, 

 mox glabrescentes, purpureo-brunnei, annotini epidermate lamellis tenuibus 

 decorticante; gemmae perulis ovato-lanceolatis acuminatis stellato-pilosis. Folia 

 decidua, ovato-oblonga v. ovato-lanceolata, acuminata, basi rotundata v. late 

 cuneata, argute serrulata, 4-7 cm. longa et 1.2-2.5 cm. lata, v. interdum 10:4, 

 supra obscure viridia, satis dense pilis 4-6-radiatis plurimis radio centrali instructis 

 conspersa, subtus cinereo-viridia v. cinerascentia ob pilos 6-10-radiatos radio 

 centrali elongato instructos molliter pubescentia, ner\'is utrinsecus 5-6 supra im- 

 pressis subtus elevatis; petioli 3-5 mm. longi, laxe stellato-pilosi. Inflorescentia 

 cormybosa, convexa et fere paniculiformis, multiflora, sparse stellato-pilosa, in 

 apice ramulorum sessilis; pedicelli plerumque graciles, ad 1.5 mm. longi, sursum 

 densius stellato-pilosi; calyx extus dense pube manifesto heteromorpha vestitus, 

 dentibus lineari-lanceolatis 5-7 mm. longis tubum duplo superantibus purpurascen-
