436 WILSON EXPEDITION TO CHINA 



alba, calycis dentes paullo superantia; stamina circiter 15, longiora 

 dentibus calycis fere aequilonga, antheris purpureis; ovarium glabrum 

 apice longe piloso excepto, stylo faucem paullo superante. Fructus 

 deest. 



Western Szech'uan: Pan-lan-shan, west of Kuan Hsien, thickets, 

 alt. 2300-3000 m., June 21 and September 1908 (No. 2382). 



Neillia rihesioides seems most nearly related to N. sinensis Oliver, which differs 

 in its slender pedicels, longer calyx-tube, with longer lanceolate teeth, and in 

 the glabrous leaves. Our specimens of Wilson's No. 2382 contain two branches, 

 one with a glabrous calyx-tube which I consider the typical form, and one with a 

 somewhat shorter, finely pubescent calyx-tube only 4.5 mm. long.

Many of the specimens differ from the original description in having the calyx- 

 tube furnished with long gland-tipped bristles, otherwise the specimens from the 

 different provinces are remarkably uniform in foliage and flowers. A specimen 

 from Yunnan, however, seems so different that it should be distinguished at least 

 as a variety, and its description may be added here. 



Neillia sinensis, var. caudata Rehder, n. var. 



A typo differt foliis manifeste trilobatis longe caudato-acuminatis, majoribus 

 ad 11 cm. longis, lobis acuminatis, floribus brevius pedicellatis pedicellis 2-3 mm. 

 longis, tubo calycis breviore circiter 8 mm. longo glanduloso-setoso. 



Yunnan: Mengtze, east mountains, alt. 2000 m., A. Henry (No. 9669; shrub, 

 3 m., flowers pink). 



In foliage this variety resembles N. thyrsiflora G. Don, which also occurs in 

 Yunnan and is represented by Henry's No. 12275 from Szemao, No. 9149 from 

 Mengtze and by No. 13653 from south of the Red River; the flowers, however, 

 differ but little from those of A'^. sinensis. 



There is another specimen of Neillia from Yunnan collected by A. Henry near 

 Mengtze which represents a new species, the description of which is appended 

 here.
