Trithuria lanterna is a species of plant in the family Hydatellaceae endemic to Australia.[3]
Description
[edit]Vegetative characteristics
[edit]Trithuria lanterna is a 10 mm tall and 30 mm wide,[4] annual herb[5][6] with very short stems bearing fibrous roots and basal, linear,[5] 5–18 mm long, and 0.8 wide leaves.[5][7] It often displays red colouration.[5]
Generative characteristics
[edit]It is a monoecious species with bisexual reproductive units ("flowers").[6] The several, sessile[5] reproductive units have 2–4[6] lanceolate, 2–3 mm long involucral bracts,[5] 1–2 stamens with 0.6–1.0 mm long anthers attached to[6] up to 1.5 mm long filaments, as well as 6-20 carpels. The ovoid-trigonous, 0.4 mm long, and 0.2 mm wide fruit with three prominent ribs is indehiscent,[5] or at least in one case dehiscent.[6] The ovoid, 0.3 mm long, translucent seed with a dark apex[5] is smooth.[5][6] Flowering occurs from April to June.[7][8]
Distribution
[edit]It is native to the Northern Territory, Queensland, and Western Australia.[3]
Taxonomy
[edit]It was published by David Alan Cooke in 1981.[3][5] The type specimen was collected by R.L. Specht on Bickerton Island in the Gulf of Carpentaria, South Bay, Northern Territory, Australia on the 14th of June 1948.[5][6] It is placed in Trithuria sect. Hamannia.[9]
Etymology
[edit]The specific epithet lanterna, from the Latin lanterna meaning lantern, refers to the morphology of the pericarp, which has a three-windowed structure resembling a lantern.[5]
Conservation
[edit]It is not threatened.[8] The Nature Conservation Act status is least concern.[1] Likewise, the IUCN conservation status is least concern (LC).[2]
Ecology
[edit]It occurs in ephemeral pools,[10] seasonal swamps dominated by Melaleuca leucadendron,[5] and stream margins.[8]
