Steml-% ft., apparently geniculately ascending, smooth, purplish ; nodes glabrous. 

 Leaves 2-3 by ^-| in., flat, green, smooth, 5-7-nerved and striate, midrib slender; 

 base rounded or narrowly cordate ; sheath purple, margin fimbriately ciliate ; 

 ligule a row of hairs. Panicle 4 in., branches in 6-8 rather distant fascicles of two 

 or three, lowest 2^ in. long. Spikelets very pale ; gl. I very deciduous (so that the 

 mature spikelet appears 3-glumed), but leaving a distinct scar ; II more coriaceous, 

 nerves more distinct ; III and its palea sometimes very small and empty. A very 

 curious grass.

Stem geniculate and ascending below, leafy usually up to the panicle. Leaves 

 membranous and sheaths glabrous ciliate or hairy above or all over ; ligule very 

 short, ciliate. Panicle ovoid. Spikelets variable in size ; gl. II very persistent. 

 llesembles Sphcerncaryum elegans and often mixed with it in Herbaria. As Trimen 

 has pointed out (Journ. Linn. Soc. 1. c.) this, according to Herbi, Linn. & FL Zeyl. 

 is P. arborescens, Linn., described as being as high as the loftiest trees. This error has 

 no doubt originated from its having been accidentally assorted with an Arundinaria 

 in Herb. Linn.
