172 ORCHIDS OF THE CAPE PENINSULA. 
leaves are generally broader than in the allied species. Small 
specimens have occasionally only four flowers, but generally they bear 
more than six, and frequently ten or twelve. In one season I saw a 
considerable number of specimens on which all the flowers, or so far 
as I examined them, had two pollinary glands. 
In my herbarium isa single 2-flowered scape of a Disa belonging to 
this group, which was gathered on the slopes of the Devil’s Peak, in 
the valley leading from Cape Town up to the neck between it and 
Table Mountain, in March, 1884, by Dr. R. Marloth. It has a 
8-lobed galea, the middle lobe longer and subacute, the side lobes 
rounded and spreading; the lip appears to be oval, entire and straight; 
the petals similar to those of D. graminifolia, with which species it 
was found growing. I did not see the specimen until it was dried, and 
am unwilling to dissect or describe it until more shall be found. 
Meantime it is commended to the research of younger botanists and 
Orchid-lovers.

The bright orange-red flowers, and the long, thin, straight spur 
readily distinguish this species from any other. It is allied to the
