The interesting Mesembryanthemum which occupies the 
lower half of our plate is another of the fruits of the 
Percy Sladen Memorial Expedition to the Orange River, 
led in 1910-11 by Professor Pearson of Cape Town. 
Like its companion this species, J/. stylosum, is a hitherto 
uncharacterised one, belonging to the same natural group, 
though in this instance the welding of the two leaves 
forming each corpusculum is much less complete and the 
resultant bodies are deeply 2-lobed at the apex. J. 
stylosum was collected on the plains between Chubiessis 
and Stinkfontein in Little Namaqualand, and the plant 
from which our illustration has been prepared formed 
part of the same munificent accession to the succulent 
collection at Kew for which the institution is indebted to 
the Percy Sladen Trust and to the travellers who, thanks 
to their assistance, were enabled to investigate so 
thoroughly the vegetation of a considerable portion of 
western Cape Colony. The flowers in M. stylosum are 
bright yellow; they open in the day time and only in 
bright sunshine. They last for five to six days and are 
JANUARY, 1915.
