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 Wen-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. muUiflora 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. Veiichiana 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. muUiflora. 

 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.
