| Tasmania has
six
native species of Stylidium. These are
characterised by the trigger plant habit- where the flowers have the
style and stamens fused together to form a column that springs
across the flower when its bottom is tickled. Three species are
perennial rosette plants with numerous leaves. These are the very
widespread and common, S. graminifolium, which has
leaves less than 3mm wide; S. dilatatum, which is common in
dry places and has leaves more than 3mm wide; and S. armeria,
which has thick, broad leave and short thick flowering stalks and
grows on rocks in the salt spray zone of the west, south and far
south-eastern coasts. The other three species are small ephemeral
plants with few leaves.
n.b. Stylidium inundatuam is probably not native to Tasmania
(specimens previously identified as such were probably another of
the ephemeral species). |
