20 WILSON EXPEDITION TO CHINA 
styli 3, stamina subaequantes. Capsula hemispherica, 4 mm. diam., lobis reflexis 
deciduis. 
= Yunnan: Mengtze, “N. Mts.", alt. 1800 m., A. Henry (No. 9475°). 
Differs from the type chiefly in its few-flowered inflorescence, white petals, and 
in the apex of the filaments or of the teeth of the filaments being obtuse. Possibly 
a distinct species. 
15. Deutzia Wilsonii Duthie in Bot. Mag. CXXXII. t. 8083 (1906). 
Eastern Szech’uan: South Wushan, cliffs, May 1901, E. H. Wilson (Veitch 
Exped. No. 1916*). In cultivation; raised from seed collected by E. H. Wilson 
(Veitchian nurseries, Combe Wood). 
This and the following three species are closely related to D. discolor Hemsley, 
and I am not yet quite convinced that they are really specifically distinct; the 
characters on which they are based seem to be rather slight and inconstant, but 
as the material I have seen of each of these species is rather scant, I do not feel 
justified to make a change, until more and completer material is available.

Raised from seed collected by E. H. Wilson in Hupeh and cultivated in the 
Veitchian nurseries, Combe Wood: Ex hort. Veitch. No. 1182/2, June 6, 1905 (Herb.

Western Hupeh: without locality, June 1900, E. H. Wilson (Veitch Exped. 
No. 940); June 1901 (No. 1998). Raised from seed collected by Farges in Szech'uan 
and first distributed by Lemoine of Nancy. 
18. Deutzia reflexa Duthie in Gard. Chron. ser. 3, XL. 238 (1906). 
Raised from seed collected by E. H. Wilson in Hupeh and cultivated in the 
Veitchian nurseries, Combe Wood; Wilson, No. 1253, June 2, 1910 (W. J. Bean in 
Herb. Kew.). 
19. Deutzia discolor Hemsley. See p. 12. 
19 x 20. Deutzia discolor X mollis Rehder, n. hybr. 
: Frutex ramulis junioribus parce stellato-pilosis, annotinis peridermate castaneo 
in lamellas tenues soluto. Folia oblonga, acuminata, basi late cuneata v. rotun- 
data, argute serrulata, 4.5-6 cm. longa et 1.5-2.2 em. lata, supra pilis 4-5-radiatis 
conspersa, subtus molliter pubescentia, pilis 7-10-radiatis (plerumque 8-radiatis) 
radio centrali praesertim ad nervos instructis obtecta; petioli pilis heteromorphis 
praediti, 3 mm. longi. Cyma convexa multiflora; calycis dentes ovato-oblongi, 
abrupte acuminati, tubum pube homomorpha obtectum aequantes; petala 5-6 mm. 
longa, ovato-oblonga, aestivatione plerumque valvata, sed etiam partim imbricata; 
stamina petalis triente breviora, filamentis staminum exteriorum interdum e basi 
dilatata sensim attenuata sed saepius subito contractis et angulatis, interiorum 
plerumque infra apicem in dentes brevissimos productis, antheris sterilibus; styli 
tres, stamina paullo superantes.

Wilson’s No. 1917 is quoted by the author of D. mollis as belonging to that 
species and it looks indeed at the first glance only like a slight variation, but a closer 
examination reveals certain features which indicate at once its hybrid origin, 
particularly the irregular aestivation and the sterile anthers. All the other char- 
acters in which the plant in question differs from D. mollis point toward D. discolor 
as the other parent; the stellate hairs of the under side of the leaves have 12-14
