Content
Description
Annual with fibrous roots (perennial under favourable circumstances?).

Asia-Tropical, warm regions of the whole world present
Widely spread, in the warm regions of the whole world; throughout Malesia, but apparently nowhere common.
Notes
Polymorphic. C. novae-hannoverae BOECK., with few-flowered spikelets and narrow, dense spikes, cannot be separated satisfactorily from typical C. odoratus. In MAYR 230 from New Guinea, Arfak Mts, 1900-2100 m, the tips of the glumes do not reach the bases of those above, thus exposing a part of the rachilla, a character also found in the N. American C. engelmannii STEUD.
