Widely differing in shape as the leaves of this species do from 
ose of Leucodon tomentosus, there yet is a close affinity be- 
tween the two plants, and it is the more satisfactory to find how 
nearly their peristomes agree together. The present plant is 
very beautiful, of a bright shining yellow colour in the leaves, 
while the lower parts of the stem are covered with a ferruginous 
down. J
