A trailing shrub upon rocks in ravines, abundant on Mount Victoria 
and some other places in Hong-Kong, flowering in June, fruiting in 
December. The globose capsule and fringed seeds had at first induced 
me to refer it generically to Coptosapelta of Korthals, a Borneo plant, 
described as having a similar trailing habit and leaves of the same shape. 
As however the flowers of the latter genus are unknown, the fructifica- 
tion is terminal, racemose, and bracteate, and the capsule woody, it is 
probable that the flowers will show still more marked generic differ- 
ences. Besides, I do not understand the dehiscence of the capsule de- 
scribed as “in mericarpia duo loculicida," unless it be that each valve - 
of the capsule carries with it the half of each placenta, which is not the 
case in our plant. Among older genera, Thysanospermum comes nearest 
to the American genus Manettia, in which the wing of the seeds is also. 
sometimes toothed, but the habit, the corolla, and capsule show abun: 
dant points of generic distinction. ;
