From efi thread :

Saccharum ravennae has become rather rare nowadays may be due to filling up of terai grasslands and expansion of roads. It is a very tall grass and can be identified by the small awn projecting out of the spikelet in addition to the hairs. It has decompound panicles (branched and rebranched) whereas S.spontaneum has unbranched panicle branches almost like a raceme. The leaves of Saccharum ravennae are also broader. The panicles are purplish in S.r and silvery in S.spontaneum.
