PRAEGER—SOME ASIATIC SEDUMS. 81 
pubescence of leaf and stem in S. purpureoviride divides it easily 
from S. bupleuroides and S. discolor.

large flowers). 
There can be no doubt that ae rariflorum, N. E. Brown, which 
was described from an immature specimen (Herb. Kew) and is 
now in cultivation at Kew, is referable here. S. Farreri, W. W. 
Sm., also comes so close that it cannot be considered distinct. 
S. dumulosum is evidently a variable species as regards the 
length of the parts of the flower and the erosion of its petals, but 
all the specimens examined are easily referable to a well-marked 
general type characterised by linear leaves, congested inflores- 
cence, linear-deltoid acute sepals, lanceolate or ovate-lanceolate 
acuminate flagellate erect petals, and short quadrate scales. The 
variations referred to as noted in the specimens examined may 
be shown as follows (measurements in mm.

Another variable feature is in the stems, which are sometimes 
mammillate near the base, sometimes smooth. The stems vary 
in height from 3 inches (Hugh) to 9 inches (Clemens), but this 
probably is due to habitat. Farreri is a handsome, stout form, 
with long sepals and broad strongly eroded petals ; but in view of 
the variability in these respects of the examples of dumulosum 
Available, it seems better not to award it varietal rank till we 
know more about the species.
