142 WILSON EXPEDITION TO CHINA 



1907 (No. 254, in part). Western Szech'uan: near Tachien-lu, 

 thickets, alt. 2300 m., June 1908 (No. 1879, in part). 



Lonicera Henryi, var. subcoriacea Rehder, n. var. 



A typo recedit foliis subcoriaceis nitidulis majoribus ovato-oblongis 

 6-10 cm. longis et 2.5-4 cm. latis omnino glabris costa media supra 

 strigillosa excepta. Ramuli in parte superiore dense strigillosi, in in- 

 feriore plerumque glabri; petioli dense strigillosi, pedunculi hirti, 

 bracteae bracteolaeque ciliatae; flores 2 cm. longi, tubo quam limbus 

 longiore. 



Western Szech'uan: Yung-ching Hsien, thickets, alt. 1800-2100 

 m., September 1910 (No. 4097); Wa-ssu country, W6n-chuan Hsien, 

 alt. 1200-1800 m., July 1908 (No. 1879, in part); near Mong-kong Ting, 

 thickets, alt. 1500-1800 m., June 18, 1908 (No. 1879, in part). 



In the shape of the foliage this variety resembles very much L. fuchsioides 

 Hemsley, but that species is easily distinguished by the perfectly glabrous branch- 

 lets and inflorescence, by the larger flowers and by the looser and more elongated 

 terminal inflorescence. No. 1879 forms a transition to the type, as the leaves of 

 the lateral flowering branchlets are narrower, often slightly ciliate, and pubescent on 

 the midrib beneath.

Lonicera similis Hemsley, var. Delavayi Rehder n. var. 

 Lonicera Delavayi Franchet in Jour, de Bot. X. 301 (1896). 



Western Hupeh: Fang Hsien, thickets, alt. 1800 m., October 



1907 (No. 589); July 1907 (No. 1869). Western Szech'uan: Hung- 

 ya Hsien, sandstone boulders," alt. 300-1200 m., June and September 



1908 (No. 936). 



Lonicera Delavayi differs from L. similis only in the absence of the pubescence, 

 and as many specimens are intermediate between the two in the amount of pu- 

 bescence, it seems more natural to treat L. Delavayi only as a glabrous or gla- 

 brescent variety of L. similis. 



Lonicera japonica Thunberg, Fl Jap. 89 (1784). 

 Western Hupeh: around Ichang, common, alt. 300-600 m., May
