| Tasmania has a
single introduced species of the large African genus of orchids,
Disa (Disa bracteata). This is the only species of orchid
known to be naturalised in Tasmania. This weedy species has large,
dense
erect flowering stems (up to 75 cm tall) with numerous small,
greenish
flowers. The inflorescence somewhat resembles an asparagus spear. It resembles some Microtis species, but the flowers
have small, yellow tongue-like labella (and the flowers are no
inverted). The leaves are narrow, with many veins. |
