No. 12,932. Aug. 1914. 
This species, of which seedlings have been raised from 
Forrest’s seeds, is one of the Selense series, and promises to be 
an acquisition to our gardens. It is a low-growing shrub with 
small neat leaves and bears many-flowered trusses of flowers, 
the colour of which is probably pink, and it produces narrow 
sickle-shaped dark purple fruits. Forrest’s specimens are all in 
fruit or passing into fruit, and the flowers available are shrivelled 
around the ovaries beginning to develop into fruit. Some 
modification of the description given above may be necessary, 
therefore, when more satisfactory flowers are forthcoming. 
In Forrest’s collection are two plants which resemble Rh. 
rhaibocarpum, but which in default of better illustration 1 
hesitate to identify with it. They are ticketed :— 
E.N.W. Yunnan. Kari Pass. Mekong-Yangtze divide. Alt. 
11,000 ft. Lat. 27° 40’ N. Amongst mixed scrub. Shrub of 
4-6 ft. Infruit. G. Forrest. No. 12,950. Aug. 1914. 
E.N.W. Yunnan. Shweli-Salween divide. Alt. 12,000 it. 
Lat. 28° ro’ N. Open rhododendron forest. Shrub of 8-10 
ft. Foliage only. G. Forrest. No. 13,560. Oct. 1914. 
Both of them have leaves approaching more nearly the 
elliptic, and the remarkable biform indumentum of shoot and 
leaf-petiole seen in Rh. rhaibocarpum does not show on them. 
There are, however, no young spring shoots, and we know this 
indumentum soon falls off. No. 12,950 wants the yellow cauli- 
flower-glands of the leaf under-surface. No. 13,560 is specially 
noticeable because of the russet autumn-tint of the older leaves. 
Coming from the Kari Pass, as does Rh. rhaibocarpum, No. 12,959 
may be merely a local divergent from the type. No. 13,560 aS 
a Shweli-Salween divide plant is more likely to be distinct. 
From the specimens of both of them good seeds have been 
extracted and one may hope for germination. 
_ There is yet another plant represented in Forrest’s collec 
tion by two sets of specimens (in foliage only) which also 
belong to the Selense series. The tickets on the specimens

W. Yunnan. Western flank of the Shweli-Salween divide.
