426 WILSON EXPEDITION TO CHINA 
Western Szech’uan: south-east of Tachien-lu, thickets, alt. 
2000-2300 m., June and October 1908 (No. 1316, type); west and 
near Wén-ch’uan Hsien, thickets, alt. 2000-2300 m., July 1908 (No. 
2275); south-east of Tachien-lu, thickets, alt. 2300-2600 m., October 
1910 (No. 4406); Mupin, woodlands, alt. 2000-2500 m., September 
1910 (No. 4224). 
This species is distinguished by its glabrous calyx and ovary and by the leaves 
being hairy on the veins only. In this respect it resembles C. Henryi Hemsley and 
C. multiflora Hance, but the first differs from it in its perfectly free, elongated ovary 
and ovate-oblong sepals, and the second in its entire nectaries and indistinctly 
toothed calyx. It seems more closely related to C. sinensis Hemsley, which differs, 
however, in the pubescent cuneate leaves and in the usually pubescent calyx and 
ovary, and to C. Veitchiana Bean which is easily distinguished by the densely 
pubescent calyx and ovary and larger fruit. Our material consists of old flowers 
from which the petals and stamens have fallen, and of fruiting specimens only. 
No. 4224 differs slightly in having most of the leaves nearly orbicular and the 
apex of the shoot and the young leaves on the under surface hairy all over; the 
older leaves, however, are glabrous. Young seedlings sometimes exhibit this same 
phenomenon as is shown by specimens before us, raised from No. 1316. 
This new species is very floriferous and quite common in the margins of woods 
and thickets throughout western Szech’uan. We have pleasure in naming it for 
Miss Ellen Willmott, who exhibited a plant of it before the Royal Horticultural 
Society of London on March 5, 1912, under the erroneous name of C. multiflora. 
The flowers were described as bright ‘yellow and very fragrant. A photograph of 
this plant is reproduced under the same name in Gardeners’ Magazine LV. 191.
