Conocephalum
''Conocephalum'' is a genus of complex thalloid liverworts in the order Marchantiales and is the only extant genus in the family Conocephalaceae.AKIYAMA, H. (2022). Morphological and ecological diversification of Conocephalum conicum complex in Japan and Taiwan. ''Humans Nat'', ''32'', 1-45. Some species of ''Conocephalum'' are assigned to the ''Conocephalum conicum'' complex, which includes several cryptic species. ''Conocephalum'' species are large liverworts with distinct patterns on the upper thallus, giving the appearance of snakeskin. The species ''Conocephalum conicum'' is named for its cone-shaped reproductive structures, called archegoniophores. Common names include snakeskin liverwort, great scented liverwort and cat-tongue liverwort. Species of ''Conocephalum'' are relatively common and widely distributed throughout North America, Europe and East Asia. ''Conocephalum'' often occurs in moist and shaded habitats and are also found in open woodlands, sandy banks, wet roc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Marchantiales
Marchantiales is an order of thallose liverworts (also known as "complex thalloid liverworts") that includes species like ''Marchantia polymorpha'', a widespread plant often found beside rivers, and '' Lunularia cruciata'', a common and often troublesome weed in moist, temperate gardens and greenhouses. As in other bryophytes, the gametophyte generation is dominant, with the sporophyte existing as a short-lived part of the life cycle, dependent upon the gametophyte. The genus ''Marchantia'' is often used to typify the order, although there are also many species of ''Asterella'' and species of the genus ''Riccia'' are more numerous. The majority of genera are characterized by the presence of (a) special stalked vertical branches called archegoniophores or carpocephala, and (b) sterile cells celled elaters inside the sporangium. Phylogeny (extant Marchantiales) Based on the work by Villarreal et al. 2015 Phylogeny (extant and extinct Marchantiales) Extinct complex thalloid ...

Complex Oil Bodies
The oil bodies of liverworts, occasionally dubbed “complex” for distinction, are unique organelles exclusive to the Marchantiophyta. They are markedly different from the oil bodies found in algae and other plants in that they are membrane-bound, and are not associated with food storage. The organelles are variable and present in an estimated 90% of liverwort species, often proving taxonomically relevant. As a whole, the formation and function of the organelles are poorly understood. Complex oil bodies are recognized as sites of isoprenoid biosynthesis and essential oil accumulation, and have been implicated with anti-herbivory, desiccation tolerance, and photo-protection. Structure and content The oil bodies of liverworts are recognizable using light microscopy, and they were first officially described in 1834 by Huebener from the plant ''Mylia'' ''taylorii''. They were noted as transparent drops, with a shining, membranous texture. They are secretory organelles bound by a si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liverworts
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 differ ...

Calcareous
Calcareous () is an adjective meaning "mostly or partly composed of calcium carbonate", in other words, containing lime or being chalky. The term is used in a wide variety of scientific disciplines. In zoology ''Calcareous'' is used as an adjectival term applied to anatomical structures which are made primarily of calcium carbonate, in animals such as gastropods, i.e., snails, specifically about such structures as the operculum, the clausilium, and the love dart. The term also applies to the calcium carbonate tests of often more or less microscopic Foraminifera. Not all tests are calcareous; diatoms and radiolaria have siliceous tests. The molluscs are calcareous, as are calcareous sponges ( Porifera), that have spicules which are made of calcium carbonate. In botany ''Calcareous grassland'' is a form of grassland characteristic of soils containing much calcium carbonate from underlying chalk or limestone rock. In medicine The term is used in pathology, for example i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...
