248 DR. M. T. MASTERS ON THE SOUTH AFRICAN SPECIES 
cies between the inner series of glumes and the stamens or the 
staminodes is of interest, as it may possibly represent an outer 
series of stamens alternating with those usually present, which are 
opposite to the inner glumes. Should this view of the nature of 
the disk be correct, the normal symmetry of the flower would be 
restored. 
R.? restuc#rormis, Nees, MS. Culmis cxspitosis, erectis, sub- 
compressis (sesquipedalibus, diametro penne corvinz), simplicibus vel

obtusiusculo longe setaceis; spiculis pluribus, in cymam densam 
terminalem obovatam aggregatis, singulis erectis, plurifloris, eylın-

femineo chartaceis); filamentis capillaribus; antheris oblongis, apicu-

In the absence of ripe fruit, there remains a doubt whether 
this very distinct-looking species belong really to this genus or 
not. So far as I have been able to ascertain, Nees has nowhere 
published the species under either of the names affixed to it in 
his handwriting in Dr. Sonder's herbarium. The female plant 
almost precisely corresponds with the male, mutatis mutandis. 
In the male plant the flowers are somewhat curved laterally, so 
that one of the outer lateral glumes becomes thereby much more 
conduplieate than the other.
