228 DR. M. T. MASTERS ON THE SOUTH AFRICAN SPECIES 
it may be distinguished by the vertieillate ascending, not spread- 
ing branches. Both the species just named vary a great deal in 
their degree of luxuriance and in the absence or presence of 
leaves.

Lamarck's figure evidently belongs to the plant subsequently 
referred to R. echinatus by Kunth, which must now be abandoned. 
Lamarck's name has precedence over that of Sprengel (see E. 
Sprengelii, Mast.). The female plant is not yet known; it may 
probably, when discovered, turn out to be a species of Hypodiscus 
rather than of Restio.

The two forms here associated appear at first sight sufficiently 
distinct; but a more careful examination will show that the only 
points of difference between the two consist in this, that the 
male spikelets are &maller than the female, and are moreover very 
numerous and densely crowded together, while in the female 
plant the spikelet is comparatively large and solitary or geminate. 
In all other essential points the two plants agree, and hence I 
have ventured to combine them into a single species.

The variety B, considered by Steudel to form a distinet species, 
diders from Thunberg’s plant in having broadly oblong obtuse 
glumes. Probably this is the normal condition of the species, the 
linear filiform state being simply the result of arrested growth.
