Treubia Lacunosa
''Treubia lacunosa'' is a species of liverwort in the family Treubiaceae that is found across New Zealand in moist shady areas on logs or soil. The organism is relatively complex for a liverwort, and hosts endosymbiotic fungi which provide it with growth-inhibiting nutrients. Description ''Treubia lacunosa'' grows flat along the ground with a single fleshy but brittle axis. Two rows of lobes extend laterally outwards from this axis, and there are small upright lobules at the base of each. The entire liverwort is around 1.5 cm wide and 4–9 cm long. There are mucus-covered hairs around the rhizoids and sex organs. The sporophyte rises from around the apex of the lobe, and has a very large seta and relatively small foot. Taxonomy The diversity of ''Treubia lacunosa'' may actually consist of two species, since there are two separate populations of the species in New Zealand. One grows primarily in sheltered forest areas, while the other is found in more open and exposed habitat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Treubia Scapanioides
''Treubia scapanioides'' is a species of liverwort in the family Treubiaceae. Until recently, the genus was placed in the order Metzgeriales. There are only 6 species in the genus ''Treubia''. Five are native to Australasia but ''T. scapanioides'' is known only from Chile.Schuster, Rudolf M. (1992). The Hepaticae and Anthocerotae Hornworts are a group of non-vascular Embryophytes (land plants) constituting the division Anthocerotophyta (). The common name refers to the elongated horn-like structure, which is the sporophyte. As in mosses and liverworts, hornworts have ... of North America (Volume 5 ed.). pp. 332–333.

Marchantiophyta
The Marchantiophyta () are a division of non-vascular land plants commonly referred to as hepatics or liverworts. Like mosses and hornworts, they have a gametophyte-dominant life cycle, in which cells of the plant carry only a single set of genetic information. It is estimated that there are about 9000 species of liverworts. Some of the more familiar species grow as a flattened leafless thallus, but most species are leafy with a form very much like a flattened moss. Leafy species can be distinguished from the apparently similar mosses on the basis of a number of features, including their single-celled rhizoids. Leafy liverworts also differ from most (but not all) mosses in that their leaves never have a costa (present in many mosses) and may bear marginal cilia (very rare in mosses). Other differences are not universal for all mosses and liverworts, but the occurrence of leaves arranged in three ranks, the presence of deep lobes or segmented leaves, or a lack of clearly diff ...

Dioicous
Dioicy () is a sexual system where archegonia and antheridia are produced on separate gametophytes. It is one of the two main sexual systems in bryophytes. Both dioicous () and monoicous gametophytes produce gametes in gametangia by mitosis rather than meiosis, so that sperm and eggs are genetically identical with their parent gametophyte. Description Dioicy promotes outcrossing. Sexual dimorphism is commonly found in dioicous species. However, according to Bernard Goffinet sexual dimorphism is rare in dioicous moss species. Dioicy is correlated with reduced sporophyte production, due to spatial separation of male and female colonies, scarcity or absence of males. The term dioecy is meaningless for bryophytes because it refers to the sexuality of sporophytes. Nonetheless dioecy and dioicy are comparable in many respects. Etymology The words dioicous and di(o)ecious are derived from οἶκος or οἰκία and δι- (di-), twice, double. (''(o)e'' is the Latin way of tra ...

Gametophyte
A gametophyte () is one of the two alternation of generations, alternating multicellular organism, multicellular phases in the life cycles of plants and algae. It is a haploid multicellular organism that develops from a haploid spore that has one set of chromosomes. The gametophyte is the Sexual reproduction of plants, sexual phase in the life cycle of plants and algae. It develops sex organs that produce gametes, haploid sex cells that participate in fertilization to form a diploid zygote which has a double set of chromosomes. Cell division of the zygote results in a new diploid multicellular organism, the second stage in the life cycle known as the sporophyte. The sporophyte can produce haploid spores by meiosis that on germination produce a new generation of gametophytes. Algae In some multicellular green algae (''Ulva lactuca'' is one example), red algae and brown algae, sporophytes and gametophytes may be externally indistinguishable (isomorphic).
