Vernacular names

Campynema is a genus in the family Campynemataceae first described in 1805.[1][3] It contains only one known species (monotypic), Campynema lineare, endemic to the island of Tasmania in Australia.[2][4] Its closest relative is Campynemanthe, endemic to New Caledonia,[5] sole other genus of the family.

Campynema lineare

C. lineare, also known as the green mountain lily,[6][7] is a small inconspicuous erect herb that grows to 15–30 cm in height. Its leaves consist of a single, curved basal leaf, with smaller leaves ascending up the flower stem.[7] It is most distinguishable by its striking green flower, which blooms in summer.[7] The flower is usually solitary, with 6 green tepals, sometimes with a burgundy tinge and developing brown edges with age,[7] lacking apparent nectaries.[8] The anthers are dorsifixed, styluli are free but thickened and contiguous below. The seeds are numerous and are flattened, sometimes almost discoid, with a spongy outer coat.[8] It is a geophyte,[9] and its leaves are deciduous in winter.

C. lineare is approximately 57 million years old.[10] It is considered to a key member of Tasmania's palaeoendemic flora.[10] A study of the gene sequences of RuBisCO in C. lineare, found that the familyCampynemataceae is the oldest of the order Liliales.[11]

C. lineare was once considered to be part of the family Liliaceae.[7]

Distribution

C. lineare can be found in boggy sites in the central, western and central mountains of Tasmania, mostly in the subalpine and alpine regions.[12] It is most commonly found in herbfields, heathlands, cushion plant communities, and lake edges.[13]
Threats and Conservation

C. lineare is not considered under any specific threats due to being situated predominantly in protected areas,[14] however some of the habitats in which it is found are predicted to decline due to climate change.[15] The most likely declines in Australian alpine ecosystems have been shown to be in alpine herbfield and cushion plant communities.[15] Due to its palaeoendemic status, the Tasmanian Parks and Wildlife Service consider C. lineare to be of high conservation significance.[14]
