Western Szech'uan: west of Tachien-lu, Tongolo, moorland 
thickets and heaths, alt. 3300-4300 m., June and September 1908 
(No. 1328; bush 1-2 m. tall, flowers rose-pink); without precise 
locality, alt. 3500 m., June 1904 (Veitch Exped. No. 3929). 
: The size of the calyx varies considerably in this species as it does in all species 
in which the bud-scales and bracts subtending the flowers are persistent. The 
small, pale pink flowers readily distinguish this plant from its Chinese allies. It 
is, however, very closely allied to R. fragrans Maximowicz which has large, more 
Tugulose leaves, larger flowers and a different calyx. 
Sect. 2. LEPIPHERUM G. Don (Osmothamnus Maxim). 
Corolla funnelform to campanulate-rotate, stamens exceeding its tube; flowers 
terminal. Leaves densely lepidote on both surfaces except in Group e. 
Group a. 
Stamens slightly exceeding the tube, style shorter than the tube of the purple 
Corolla, not villose at the mouth.

Western Szech'uan: north of Tachien-lu, Ta-p'ao-shan, moor- 
lands, alt. 4000-5000 m., July 7, 1908 (No. 3466; bush 30 cm.-1 m. 
tall, flowers purple); grass lands around Tachien-lu, alt. 3600-5000 m., 
June 1904 (Veitch Exped. No. 3934). 
This is a very common alpine shrub in the neighborhood of Tachien-lu. We 
find the characters on which R. blepharocalyz Franchet is founded are not con- 
— On specimens before us, flowers on the same branch have the calyx- 
3 small, non-ciliolate, with marginal scales and sparingly ciliolate lobes with 
1. Without marginal scales; while others have very markedly ciliolate calyx-lobes. 
Size the calyx varies considerable even on the same shoot, as it does in all these
