548 WILSON EXPEDITION TO CHINA 



This is not closely related to any other species, and is well characterized by its 

 narrow, glabrous leaves, the glabrous 5-merous flowers and by their narrow lobes 

 often nearly half as long as the tube.

Western Szech'uan: Tung River valley, alt. 700 m., May 1904 (Veitch 

 Exped. No. 4431). 



This is a very distinct species well characterized by its thin light green rather 

 large leaves marked with conspicuous white veins and by the peduncled head of 

 yellow flowers. The whole plant is quite glabrous except the winter-buds. 



Daphne leuconeura, var. Mairei Leveille & Rehder, n. var. 



A typo recedit rhachi inflorescentiae et ramuhs junioribus et foliis juvenilibus 

 sparse strigoso-villosis.

The leaves in Maire's specimens are very young and they may present further 

 differences when fully grown.

 Northern Shensi: G. Giraldi (No. 5995, ex Nitsche). 



According to Nitsche the style in this species is comparatively long, the length 

 being given in the description as 0.5 mm., though in the accompanying note he 

 says that it is often as long as the ovary; the only other species of Daphne with a 

 similar long style is D. tenuiflora, Bureau & Franchet.

It is possible that Wilson's No. 4614 enumerated under D. gemmata belongs to 

 this species of wliich I have seen only a photograph of the type specimen and that 

 D. gracilis and D. gemmata are forms of one species. According to Pritzel's original 

 description this species has 4-merous flowers, but Nitsche states that all the flowers 

 examined by him proved to be 5-merous. I believe Nitsche's statement to be cor-
