The somewhat peculiar Crassula here figured was origin- 
ally discovered in Little Namaqualand by the late Sir 
Henry Barkly, who communicated it to Kew in 1875. The 
plants here figured were received at Kew from Professor 
H. H. W. Pearson, of Cape Town, in January, 1911; they 
formed part of a collection made during the Percy Sladen 
Expedition, and were found by Mr. Pillans, a member of 
the party, on a ridge four miles to the south-east of 
Bakhuis. Grown in a house devoted to succulent plants, 
these specimens flowered in March, 1911. While under 
these conditions the flowers produced have been white, there 
is reason to think that when fully exposed to sun and air 
in their native habitat the petals assume a reddish tinge. 
The stems too, as compared with those of the specimens 
collected by Barkly, are unusually long ; the original ones 
are only 1-14 inches high. Like other species of Crassula 
with a compact pyramidal habit, C. Barklyi is of slow 
growth and is prone, after flowering, to lose its vigour. 
The requirements of this and its nearer allies are best met 
Frsrvary, 1912.
