Diagnostics:

Paspalum longifolium is most easily distinguished by its inflorescence, which have branched into alternating rows bearing purplish spikelets. The junction of each spike with the inflorescence stalk have prominent erect hairs. Vegetatively, the leaves are long, erect, and folded at the mid-vein. The side of the leaf shealth is lined by a margin of white hairs.


Interesting Facts:

Gilliland (1971) stated that the Long Leafed Paspalum is often found at wet areas, though those I have seen are on pretty much dry land.
