SAXIFRAGACEAE. — DEUTZIA 7 
Deutzia Schneideriana Rehder, n. sp. 
Deutzia staminea Hemsley in Jour. Linn. Soc. XXIII. 277 (not R. Brown) (1888). 
Deutzia crenata Hemsley, l. c. (in part as to the Hupeh specimens) (not Siebold 
& Zuccarini). fs 
Frutex 1-2 m. altus ramulis fusco-purpureis, initio sparse stellato- 
pilosis, mox glabrescentibus, vetustioribus griseo-brunneis cortice 
detersili. Gemmae pluri-perulatae, stellato-pilosae. Folia subchar- 
tacea, elliptico-ovata, interdum ovata v. elliptico-oblonga, breviter 
acuminata, basi late cuneata v. interdum rotundata, argute serru- 
lata, 3.5-7 cm. longa et 1.5-3 cm. lata, supra pilis 5-6-radiatis laxe 
conspersa, subtus eanescentia v. albida, dense pilis 12-14-radiatis ob- 
tecta, ad venas pilis longis simplicibus instructa, utrinsecus 4—6-cos- 
tata; petioli parce stellato-pilosi, 3-4 mm. longi. Inflorescentia late 
paniculata, 3-6 cm. longa; calyx hemisphericus, dense stellato-pilosus 
dentibus triangularibus tubum subaequantibus; petala oblonga, 
circa 10 mm. longa, extus stellato-pilosa; stamina longiora petalis 
quarta parte breviora v. interdum fere aequantia, filamentis dilatatis 
apice manifeste dentatis dentibus antheram vix attingentibus; styli 
plerumque 3, graciles, stamina subaequantes. Capsula hemispheriea, 
apice leviter contracta, 5-7 mm. diam., calyce deciduo. 
Western Hupeh: Chang-o Hsien, thickets, alt. 900-1200 m., 
June 1907 (No. 2889, type) ; without locality, June 1901 (Veitch Exped. 
No. 2152, 215295); Ichang, A. Henry (No. 3571); without locality, 
A. Henry (No. 1968). 
Most nearly related to D. scabra Thunberg, which is easily distinguished by the 
leaves being only sparingly stellate-pubescent and therefore green on the under- 
Side, without simple hairs on the veins, by their crenulate-serrate margin with ap- 
pressed serratures and by the narrow, nearly cylindric panicles, while the related 
D. hypoleuca Maximowicz differs in its five styles and narrow panicles. I take 
pleasure in associating with this species the name of Mr. C. K. Schneider whose 
“Beitrag zur Kenntnis der Gattung Deutzia” (in Mitt. Deutsch. Dendr. Ges. XIII. 
172-188 (1904) is a valuable contribution to the knowledge of this genus. 
Deutzia Schneideriana, var. laxiflora Rehder, n. var. 
A typo differt praecipue foliis subtus viridibus, sparsius stellato- 
pilosis, paniculis laxioribus latioribusque. Frutex 2-2.5 m. altus. 
Folia oblongo-lanceolata, acuminata, basi rotundata v. late cuneata, 
remote et irregulariter denticulata, 5-7 cm. longa et 1.5-2.3 cm. lata, 
supra pilis 4—5-radiatis sparsius, subtus pilis 10-12-radiatis densius 
conspersa. Panicula 6-9 cm. longa et 5-8 cm. lata, ramulis infimis 
floribus inclusis 4-5 em. longis; petala 12-14 mm. longa, acutiuscula. 
Capsula 5 mm. diam. Ceterum ut in typo.
