Scientific name: Thomasia gardneri
Common name: Mt Holland Thomasia
Mt Holland Thomasia was a low, erect shrub, growing up to 50 cm in height. The fine branches, leaves and flower-heads were covered with small scales bordered with short hairs. The ovate-oblong shaped leaves were up to 2 cm long and 8 mm wide. The flowers were arranged in either one or two flower-heads at the ends of the branches. Each flower had pink sepals, approximately 1 cm long, with prominent veins and scales on the outside. The sepals were divided into five lobes. The five small petals, about 1.5 mm long, were rounded and tapered at the base. The anthers (pollen producing part of flower) were oblong in shape. The ovary was densely covered with scales (Brown et al. 1998).
Mt Holland Thomasia was collected only once in 1929 from near Mt. Holland, Western Australia, approximately 350 km east of Perth (Brown et al. 1998; Paust 1974).
There are no details of the habitat in which Mt Holland Thomasia was found (Brown et al. 1998).
Mt Holland Thomasia was recorded flowering in September (Brown et al. 1998).
The reasons for the extinction of Mt Holland Thomasia are unknown (Brown et al. 1998)
