limb. The only species of Haworthia recorded from out- 
side South Africa is the Angolan H. angolensis, Baker, but 
it now appears that this exception is only apparent, for 
fH. angolensis has been transferred by Berger to his 
genus Chortolirion as C. angolense. The genus Chortolirion. 
Berger, was founded for the reception of those species 
referred by Baker and Engler to Haworthia which differ 
from the true Haworthias in having their leaves narrow 
and comparatively thin above, but wide and conniving 
in a balb-like fashion below. The subject of our plate, 
H. Chalwini, is a very striking species of columnar habit; 
it bears most resemblance to //. Reinwardtii, Haw., with 
which it agrees in the bronze-purple colour of the leaves 
and in the pearly protuberances on their under and 
outer surface. The material for our figure has been 
derived from a plant raised from a cutting presented 
by Dr. Marloth in 1913. This plant flowered in a 
succulent house at Kew for the first time in 
October, 1916.
