Himalayan Rhodiolas are in cultivation, and they are interesting 
plants. Farther north, in Tibet and Afghanistan, some very pecuUar 
Sedums occur, such as 5. Balfouri, S. Hohsonii, S. Karpelesae, S. 
pachyclados, which I group with the Rhodiolas. For the rest, the 
Himalayan and Tibetan flora includes a few of the Japonica series 
(which find here their western hmit), a few small annuals, and some 
miscellanea, such as the Telephium S. Ewersii. Altogether close on 
fifty species are found within this region, almost all of them being 
perennials ; about a dozen of them are in cultivation. 
China. 
In Forbes and Hemsley's " Enumeration of the Plants of China " 
(which included the area extending from Formosa on the south to 
Korea on the north), published in 1887, 28 species constituted the list 
of Sedums. The floral wealth of the interior of China was at that 
time unknown. Since then the extraordinary results of the botanical 
explorations of Henry, Wilson, Forrest, and the French missionaries 
have been pubUshed ; hundreds of new plants have been described, 
and among them are at least 90 new species of Sedum. Most of these 
are from the inaccessible western provinces, and have been described 
almost entirely from dried specimens. Very few of them are as yet 
in cultivation. Many are small plants of the Japonica section, of 
no great horticultural importance ; but they include a number of 
Rhodiolas, and some very interesting plants alHed to the section 
Telephium, for which two new sections of the genus, Pseudorhodiola * 
and Giraldiina.t have been created ; one species belonging to the first 
of these groups (S. yunnanense var. valerianoides) is in cultivation. 
The earliest Sedums to come to us from China were spectabile and 
sarmentosum, and up to the present few have followed them. Not 
more than 30 of the 120 or so species known to occur in China are at 
present in cultivation. While the Japonica section cannot be expected 
to yield much of garden value, we may look for some interesting species 
among the Chinese Rhodiolas. Some of the Chinese Sedums, such as 
S. Chaneti and S. limuloides^ are very curious plants indeed.

In Japan, the latest census (by Matsumura, 1912) puts the
