Notes

Also closely related to and possibly not specifically distinct from C. amabilis . The latter species, not known from Malesia, is mainly characterized by the very shortly mucronulate, golden or ferrugineous glumes. How- ever, in an Australian variety of C. castaneus: var. brevimucronatus , the glumes are also but shortly mucronate, and this variety is therefore only distinguishable from C. amabilis by the slightly smaller, dark glumes and the somewhat smaller nut and anther.
