8 WILSON EXPEDITION TO CHINA 
Western Hupeh: north and south of Ichang, alt. 900-1400 m., 
June and December 1907 (No. 767). 
Differs from the type chiefly in the leaves being on their under side only spar- 
ingly stellate-pubescent and therefore green, and in the looser and broader panicles. 
Deutzia pilosa Rehder, n. sp. 
Frutex metralis ramulis fuscis, junioribus pilis longis patentibus 
ferrugineis instructis, secundo anno tarde glabrescentibus. Folia 
brevissime petiolata, membranacea, ovata v. ovali-ovata v. oblongo- 
ovata, longe acuminata acumine saepe falcato, basi rotundata v. 
subcordata, argute mucronulato-serrulata, 3-6.5 cm. longa et 1.5-3 
em. lata, concoloria, supra pilis stellatis 3—4-radiatis et insuper radio 
centrali longiore instructis, subtus pilis 4—6-radiatis radio centrali in- 
structis conspersa et ad venas pilis simplicibus patentibus praedita; 
petioli dense pilosi, 1-2 mm. longi. Cyma 3-9-flora, rarius uniflora, 
bracteis lineari-lanceolatis v. ebracteata, pilis ferrugineis patentibus 
instructa, pedunculo gracili, 1.5-3.5 cm. longo; flores graciliter pedi- 
cellati; dentes calycis late ovati subito breviter acuminata, tubo 
dense pube homomorpha v. interdum heteromorpha obtecto dimidio 
breviores; petala oblongo-ovata, circa 8 mm. longa, extus dense stel- 
lato-pilosa; stamina petalis fere dimidio breviora, filamentis exteriorum 
manifeste dentatis dentibus lanceolatis faleatis antheram fere ses- 
silem multo superantibus, interiorum lanceolatis antheram faciei 
interiori cirea medium affixam gerentibus; styli 3-4, staminibus multo 
breviora, 1.5 mm. longa. Capsula subglobosa, cirea 5 mm. diam., 
calycis dentibus persistentibus incurvis. 
Western Szech'uan: west of Kuan Hsien, thickets, alt. 1200- 
1500 m., June 19, 1903 (No. 2896, type); Mt. Omei, May 1904 (Veitch 
Exped. No. 4884). 
In its spreading pilose ferrugineous pubescence and its long peduncled few- 
flowered inflorescence this is very unlike any other species. No. 4884 differs 
from the type somewhat in the heteromorphous pubescence of the calyx and in the 
less marked development of the central ray of the hairs on the upper side of the 
leaves. 
Deutzia setchuenensis Franch., var. longidentata Rehder, n. var. 
Folia ovata v. oblongo-ovata, rarius oblongo-lanceolata, 4-8 em. 
longa, concoloria, supra pilis plerumque 4-radiatis, subtus plerumque 
6-radiatis, 5-7-radiatis rarius 8-radiatis interspersis, radio centrali 
destitutis conspersa. Cyma pauciflora, longe pedunculata, pedicellis 
gracilibus; filamenta staminum exteriorum dentibus lanceolatis an- 
theram multo superantibus, interiorum lanceolata antheram faciei in- 
teriori infra medium affixam gerentia; ceterum ut in typo.
