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.
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 family Campynemataceae is the oldest of the order Liliales. [11]
C. lineare was once considered to be part of the family Liliaceae. [7]
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]
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]
