SATYRIUM. 119 
character of erect and reflexed bracts used by Lindley for a secondary 
division is inconvenient in use owing to the fact of the position of the 
bracts changing as the flowering proceeds, and in some cases it is not 
easy to decide whether the bracts are patulous or erect. 
A better subdivision may be found in the leaves. I propose to take 
one group (Humistrate), in which there are one, or more usually two, 
radical leaves, which lie flat upon and appressed to the ground; and a 
second (Adscendentes), in which the leaves are mostly more than two, 
and are erect or ascending : in no species with which I am acquainted 
is there any doubt as to which of these two subdivisions it should be 
referred. 
Distrisution.—About 57 described species are admitted. Of these 
our list includes 18 found on the Peninsula; 20 are scattered over the 
remainder of extra-tropical South Africa, chiefly along the coast 
districts to Natal; 5 are Angolan; 4 Abyssinian; 1 from Kilimanjaro 
Mt.; 6 from the Mascarene Islands; and 8 from British India. 
Besides the above there are several undescribed species from the 
Zambesi Region.
