| Tasmania has
three species of Digitaria. These are weeds with the very distinctive habit of the
inflorescence being an erect stalk ending in digitate (i.e. arranged
like fingers) cluster of spikes. The plant are loosely tufted. The leaves are up to 15cm long
and up to 8mm wide. The spikelets are groups of two or three, and appressed
to one side of a zig-zag axis.
Cynodon dactylon also
often has obviously digitate inflorescences, but is a mat forming
species with obvious stolons. Digitaria sanguinalis is
summer grass. |
