Acrobolbus pseudosaccatus, synonym Tylimanthus pseudosaccatus, is a bryophyte, a species from the liverwort family Acrobolbaceae.[1] The family grows on logs, rocks, and soil. Under certain circumstances, however, they are epiphyte, growing on other plant species.[2]

Description[edit]

The leaves of Acrobolbus pseudosaccatus have a shallow depression at the tip, and the margin is finely toothed.[2] The leaves are very fine and are translucent green. Plants are also robust in size. The finely toothed margins distinguish TylimaAcrobolbusnthus pseudosaccatus from other members in the Acrobolbaceae family.[3] The most distinctive feature, however, is the reproductive structure. The position of the reproductive structures most accurately distinguishes Acrobolbus pseudosaccatus from any other species.[4] The sporophyte (reproductive structure) develops in a pouch at the shoot apex structure.[2]

Taxonomy[edit]

The species was first described in 1963, as Tylimanthus pseudosaccatus.[5] The genus Tylimanthus was later synonymized with Acrobolbus,[6] and Tylimanthus pseudosaccatus was transferred as Acrobolbus pseudosaccatus in 2015.[5][7]

Distribution and habitat[edit]

Acrobolbus pseudosaccatus is located in the Southern Hemisphere, found in Australia.[8] They are endemic to south-east Australia in New South Wales, Victoria, and Tasmania. Their habitat requirement consists of environments which retain moisture.[9] Mostly in forests, wet sclerophyll forests or they could also be found in rainforests. The liverworts are found in environments which are either middle-aged or old-growth forests, as these provide the bryophytes with protection.[10]

Liverworts are significant in their habitats as their presence in an environment offers microhabitats.[11] The importance of the microhabitats is that it creates an environment which is essential for the survival of other organisms.[12] These organisms include protozoa, invertebrates, and eukaryotes.[13] The reasoning for why they create important microhabitats is due to bryophytes been nitrogen fixers.[12] Other organisms depend on nitrogen as it allows for those species to grow and develop, overall improving the quality of the soil.
