I have little doubt that this is De Notaris’ deua superba from . 
Upper Nubia, which I know only from the description in Ann. Sc. 
Nat. Ser. IIL, XIX. p. 369, a description wich is a mixture 
of accurate observation and sin gular misconception. De Notaris 
describes the spikelets as 3-flowered, viz. with a * neuter " flower 
at the base of the pale of the male flower and appressed to it, and 
consisting of a very short fleshy earshaped * ‘ pale KU He mistook 
sepesi a mee for an additional ** neuter "' flower. ve the

also due to erroneous observation, the fan of the keels and the 
side parts often overlapping in such a way as to produce the 
impression of several lateral nerves. Otherwise, De Notaris’ des- 
cription answers almost exactly that given here of T. gigantea.

I found the nodes always perfectly glabrous, with a single 
exception, in which near the base of a culm there were a few s 
hairs present.
