Lophocolea semiteres, sometimes known as the southern crestwort,[1] is a species of liverwort native to Australia, New Zealand, South Africa, South America, and a number of sub-Antarctic Islands.[2]

Description

Lophocolea semiteres, being a bryophyte, is a small, non-vascular plant that has a prostrate growth habit, creeping across its substrate. The plants are yellowish in colour and have rounded lateral leaves with mostly entire margins, but these become progressively emarginate to distinctly bi-lobed nearing terminal archegonia, which are surrounded by a leafy perianth.[2][3] Male plants are more common and highly distinctive.[1] Antheridia are borne intercalary on shoots, protected by modified saccate leaves.[2]

Range

The native range of Lophocolea semiteres is pan-south-temperate. In New Zealand, it is found on the main North, South, and Stewart Islands, as well as the offshore Campbell, Chatham, and Kermadec Islands.[2] It grows in all states and territories of Australia, other than the Northern Territory and Queensland.[4] The type locality of the species is Teufelsberg, in southern Africa.[5] L. semiteres also occurs in southern South America and southern temperate oceanic islands.[2] It has been introduced to Europe and the British Isles and is there considered an invasive species.[1][6]

Habitat & Ecology

As Lophocolea semiteres is a xeric-tolerant species of liverwort, it is one of the most widespread and common members of the Lophocoleaceae, if not the Jungermaniineae, particularly in Australia.[2][7] It may be found growing on soil, mortar, in lawns and gardens, but also in moist indigenous forests.[2][4] In its introduced range it grows generally on earthy or sandy banks.[1]

Etymology

The specific epithet refers to a shape - 'semiterete', meaning half-cylindrical.[8] This may refer to the shape of plant shoots, but was not recorded in the species protologue.[5]

Taxonomy

Lophocolea semiteres was first described from South Africa (now Namibia) in 1829 as Jungermannia semiteres.[5] While included in Chiloscyphus as C. semiteres by some authors,[9][10][11] others prefer to segregate the genera.[12][13] L. semiteres contains the following varieties:[2]

  • Lophocholea semiteres var. semiteres
  • Lophocolea semiteres var. retusa
