inflorescence of Cynodon.’’ Subsequently in Genera Plantarum, 
vol. iii. p. 1164 (1883), he emphasised this point and distinguished the 
ustralian group as a section, Brachyachne, from the rest of Cynodon 
(section Fibichia), adding these words: “sectiones . . . VIX non pro 
generibus propriis habendae,” and under Brachyachne, ‘‘Sectio a 
Microchloa vix nisi habitu et inflorescentia differt.” 
To those Australian species have now to be added M. obtusiflora, 
Benth., and the species figured here, both African. The spikelets of all 
those species imilar in struct d g t that they have 
to be grouped together in one superior unit, and this should be, in 
my opinion, of genericrank. The sharply keeled, not dorsally rounded 
upper glume, and the peculiar orientation of the spikelets, distinguish 
it from Microchloa and Rendlia, whilst the inversion of the proportion 
of the sizes of the glumes and the floret, as well as the delicate texture 
of the latter, exclude it from Cynodon. The rhachilla is continued 
more or less beyond the floret in all the species, as is also the case 
in Microchloa and Cynodon Dactylon, Pers., and C. transvaalensis, 
Burtt-Davy, but not in C. incompletus, Nees.—O. Starr.

tinuation of rhachilla; 4, lower glume; 5, upper glume; 6, valve; 7, valvule 
(4-7 flattened out). All enlarged.
