Dear Sir, Thank you for the links. I think they have made a grave mistake. It is ok whatever genus name they want to put, Coix and Chionachne may be treated under the same genus, though there are characters sufficient enough to treat them differently. However, both koenigii and gigantea are entirely different species. The main difference between the two genera are the shape and position of the 'bead', i.e, the female spikelet. In Coix, it is enclosed by the leaf sheath modified involucre to look like a spherical ovate to orbicular bead and completely exserted, whereas in Chionachne, the female spikelet is a compressed, oblong bead and not exserted completely and the leaf sheath is not modified into an involucre . Another major difference is the presence of stinging hairs in Chionachne, whereas Coix does not have such hairs. Hence Coix is more palatable and a good fodder, whereas Chionachne is not. Coix is more common in moist and waterlogged and abandoned agriculture fields, canal banks, etc., wheras Chionachne is a species found in similar habitat in forest areas. Regards... Manoj Chandran
