Holcus (Poaceae) 4b:243 |

Tasmania has
two introduced species of fog grass (Holcus). One
species (H. lanatus, Yorkshire Fog) is a very common weed of
pastures, roadsides and waste ground. The species are moderately
large grasses with softly hairy leaves that are up to 1cm wide. The
inflorescence is a large panicle that is fairly compact, becoming
more spreading with age. The spikelets are small (~5mm long) and
have two flowers (rarely three, but in this case the third floret is
tiny and lacking any reproductive parts). The key feature is that
the lower flower is hermaphrodite, whereas lacks an ovary. The
glumes are larger than the flowers, which have very short awns. |
