68 PRAEGER—SOME ASIATIC SEDUMS. 
In the present paper 12 new species are described and figured, 
of which 8 belong to the section Rhodiola, which is essentially 
Asiatic in distribution, and is proving to be extensively developed 
in the W. China-Tibet region, and to offer there many interest- 
ing and puzzling forms. ‘The additional members of it now 
studied have not led me to alter the tentative views I expressed 
in a recert paper * as to the extent and classification of this diffi- 
cult and complicated group. At the one end of the series, which 
I take to be the most evolved, stand S$. roseum and its allies; at 
the opposite end the Rhodiolas appear to pass into the Seda 
Genuina, forms like S. limuloides having affinities in its growth- 
form (on which the classification of Sedums has always been 
based, the flowers providing no sure ground for sub-division) to 
Rhodiolas like S. Praegerianum and S. Balfouri on the one hand, 
and on the other to some of the Mexican Seda Genuina. 
The following notes relate only to sheets now for the first time 
determined, or of which previous determinations are revised. 
Plants which were already correctly named in the collections 
are not included, except where, as in the case of S. Leveilleanum 
or S. orichalcum, their characters and affinities are discussed. 
I have not included additional stations for certain species which 
are- now known to be of common occurrence in the areas 
concerned 
The information given on the labels is given verbatim, any 
additional remarks by myself being included in parenthesis.

In the fetct- mentite i (Maire) the inflorescence is very 
strong, and the leaves, while frequently normal (as figured in. 
Proc. R. Irish Acad. xxv, Sect. B. pl. iii), tend to be shorter 
d broader, with a retuse, not pointed, apex. In the latter 
sheet (Carles) these features are emphasised, all the leaves being
