Key to Tasmanian Dicots
Iridaceae 4b:167
Although the Iris family (Iridaceae) is only a small family in Tasmania, with 6 native and 18 introduced species prominent family it is quite prominent. Some of the native species are very abundant in their habitats (e.g. Diplarrhena spp.) and some of the introduced species are widespread and significant weeds.

The leaves of most species (except Moraea  which have conventional leaves) are very distinctive. They are flat and the same on both surfaces, but are split at the base so that they form a sheath around the stem. They are typically long and narrow more or less clustered at the bases of the stems and are often in two rows, so that the stem+leaves take a flattened, fan-like form. The irises mostly have conspicuous flowers with variously coloured petals/sepals. All except Isophysis have inferior ovaries, and the species all have either 2 or 3 stamens.
