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.

 and first distributed by Lemoine of Nancy.

 19 X 20. Deutzia discolor X mollis Rehder, n. hybr. 



Frutex ramulis junioribus parce stellato-pilosis, annotinis peridermate castaneo 

 in lamellas tenues soluto. Foha oblonga, acuminata, basi late cuneata v. rotun-

 abrupte acuminati, tubum pube homomorpha obtectmn 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

Western Hupeh: June 1901, E. H. Wilson (Veitch Exped. No. 1917) (Herb. 

 Arnold Arboretum.). 



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
