Key to Tasmanian Dicots
Typha (Xanthorrhoeaceae) 4b:363  
The only genus of Typhaceae is Typha. Tasmania has two native and one introduced species of Typha. These are all emergent aquatics (though the introduced species occasionally grows in damp ground). They are large, erect plants (up to 3m tall, and with stems 2-3 cm thick) with long, grass-like leaves in two rows. The stems are topped by the unmistakeable inflorescence, which comprises a compact sausage-like section of tiny female flowers (this section is thicker than the stalk) topped by a thinner, more diffuse male section. In fruit the female section forms a mass of furry, wind-dispersed seeds.
