Trithuria austinensis is a species of aquatic plant in the family Hydatellaceae endemic to Western Australia. [1]
Trithuria austinensis is an annual herb with green to red, 20–40 mm long, linear leaves. [2]
It is a dioecious species [3] [2] and in large populations male and female plants occur at equal rates. [4] The peduncles of the reproductive units ("flowers") are 10–50 mm long. In male plants, the 2-8 reproductive units consist of 2-4 4.2–7.2 mm long, and 1.0–3.0 mm wide bracts, and 3-15 stamens. In female plants, the up to 30 reproductive units are composed of 3-4 bracts, and 17-22 carpels. The bracts of the female reproductive units exhibit two different shapes. [2]
