Thismia rodwayi
Thismia rodwayi, also known as a fairy lantern, is a non-chlorophyllous plant belonging to the Burmanniaceae family, found in the Australian states of Tasmania, Victoria and New South Wales, and in several locations in New Zealand.
The small number of known individuals of this species has put it under Schedule 5 (Rare) of the Tasmanian Threatened Species Protection Act 1995. However, Thismia rodwayi is not considered threatened by the International Union for Conservation of Nature (IUCN).
Thismia rodwayi is a small reddish-yellowish flower – the lantern – seemingly without stem and leaves. The plant most often emerges from the forest floor or lies hidden under the litter. As it does not contain any chlorophyll, the mature plant consists of a flower stalk and roots, both devoid of chlorophyll.
As a mycoheterotroph, Thismia Rodwayi is associated with a fungus, which is the true saprophyte. Its whole life cycle, and especially its reproduction, is still mostly unknown.
Thismia rodwayi is, as botanist Mark Wapstra puts it, 'aptly described' by its common name: fairy lantern. It is a very small flower, only visible as an orange and red obovate floral tube of 10 to 18 mm in length. This flower is surmounted by six perianth lobes: three inner lobes curving inward, and three outer ones spreading outward.
The flower lies atop a 0.5 to 3 cm long colourless and subterranean flower stem which bears six bracts, increasing in size toward the flower. The flower stem arises from the juncture of the 1 to 1.5 mm thick and 4 to 15 cm long roots.
Each individual plant usually produces only one flower per bloom cycle, occasionally two; plants can be found in groups of 2 to 5 (and up to 12) in an area of less than 1 m2.
Thismia rodwayi occurs in wet eucalyptus forests, mainly Eucalyptus obliqua, E. regnans, E. delegatensis and E. viminalis, between 100 and 650 m above sea level. The potential habitat in Tasmania is estimated with the RFA (Regional Forest Agreement), such as "tall E. obliqua forest" (OT) or "wet E. viminalis forest" (VW). As occurrence data for the species are sparse, the potential habitat is much more widespread than the flower itself.
