- Note
- After looking at all the East African material available, a few hundred specimens, I believe that for East Africa we are dealing with a single taxon, rotundus, with a few colour forms (and this was the basis on which specimens were mostly sorted, I think), and some variability in spikelet length and cross-section (the latter character used for distinguishing tuberosus) as well as in glume length. I am quite unable to write any key to the various forms that works on the bulk of the material; of course, the extremes are distinct, but there are more intermediate specimens than there are extreme ones. There are no constant qualitative characters separating the taxa, and hardly any convincing quantitative ones, either; geographically and habitat-wise there are no differences. Therefore I am reducing these names into synonyms of rotundus. Regarding the merkeri taxon, C.B. Clarke, when describing his new species C. merkeri only compared it to an unknown taxon, C. neuerensis; he gave the length of the culm as 30 cm. Kükenthal in E.P. 4, 20 (101) combined what was a full species ( merkeri) into a subspecies of rotundus. He did not give a key, but from his brief descriptions we can see he thought this subspecies differed from the typical one in longer culms (45–60 cm rather than 15–30 cm), and darker-coloured spikelets (dark dull red, rather than brown or dull red). Haines & Lye distinguished these two subspecies (again, without giving a key) by ‘its shorter glumes with a usually much darker colour’: glumes 2.7–3.2, rather than 3.3–4.3 mm; description of glume colour in the text overlaps for the two subspecies. Haines & Lye kept up four subspecies and varieties, based on Kükenthal taxa; Kükenthal had combined these taxa into C. rotundus. Differences between the taxa were only expressed in short sentences (rather than a key) and these have given me problems. Colour and degree of compression of the spikelet, plus glume length and glume apex configuration, were the characters used to distinguish these four taxa. Finally the taxon tuberosus was distinguished from rotundus by the original author, Rottbøll, based on a leafy (not almost leafless) culm base, a sub-simple anthela, and terete spikelets. Haines & Lye suggested that this subspecies “is very closely related to subsp. rotundus” but kept the taxa separate based on slightly longer and more acute glumes, and less terete spikelets, in tuberosus. A taxon decribed from coastal Kenya, var. taylorii, was said to differ in the tall culms (30–50 cm, quite within the range of typical rotundus); the large congested head, 3–6 cm wide of many crowded up to 3 cm long spikelets (again, well within normal range) and obtuse glumes 4–5 mm long (rather on the long side, but not excessively so). It was known only from the type.

- Note
- This is a very variable species, particularly as regards the colour and size of the glumes. The following subspecies apparently occur in Somalia: subsp. rotundus with 3.3–4.3 mm long light to dark reddish brown glumes, subsp. tuberosus (Rottb.) Kük. with 3.7–4 mm long light brown to uncoloured glumes, and subsp. merkeri (C.B. Cl.) Kük. with 2.7–3.2 mm long dark reddish brown to almost blackish glumes. Most collections are, however, too young to be referable to any of the subspecies.
