Blasiaceae
Blasiaceae is a family of liverworts with only two species: ''Blasia pusilla'' (a circumboreal species) and '' Cavicularia densa'' (found only in Japan). The family has traditionally been classified among the Metzgeriales, but molecular cladistics suggests a placement at the base of the Marchantiopsida Marchantiopsida is a class of liverworts within the phylum Marchantiophyta. The species in this class are known as complex thalloid liverworts. The species in this class are widely distributed and can be found worldwide. Phylogeny Based on the w ....

Cavicularia Densa
''Cavicularia densa'' is the only species in the liverwort genus ''Cavicularia''. The species was first described in 1897 by Franz Stephani, and is endemic to Japan, where it grows on fine moist soil. Plants are thalloid and flattened, with distinct upper and lower surfaces and a faint central strand. Thin scales grow from the underside in two rows, and in the region between the scales and the central strand are small ear-shaped ''domatia'' which harbor colonies of the blue-green alga ''Nostoc''. The plants are dioicous, with the male antheridia and female archegonia produced by separate plants. Plants may also reproduce asexually from multicellular gemmae produced in crescent-shaped receptacles on the thallus surface. The spores are spherical and apolar, with a surface devoid of ornamentation except for tiny papillae. Gametophyte development is endosporic, so that cell divisions begin inside the spore wall. This pattern of development is normally found in liverworts from xeri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marchantiopsida
Marchantiopsida is a class of liverworts within the phylum Marchantiophyta. The species in this class are known as complex thalloid liverworts.

Metzgeriales
Metzgeriales is an Order (biology), order of Marchantiophyta, liverworts. The group is sometimes called the simple thalloid liverworts: "thallus, thalloid" because the members lack structures resembling stems or leaves, and "simple" because their tissues are thin and relatively cellular differentiation, undifferentiated. All species in the order have a small gametophyte stage and a smaller, relatively short-lived, sporophyte, spore-bearing stage. Although these plants are almost entirely restricted to regions with high humidity or readily available moisture, the group as a whole is widely distributed, and occurs on every continent except Antarctica. Description Members of the Metzgeriales typically are small and thin enough to be translucent, with most of the tissues only a single cell layer in thickness. Because these plants are thin and relatively undifferentiated, with little evidence of distinct tissues, the Metzgeriales are sometimes called the "simple thalloid liverwor ...

Blasia Pusilla
''Blasia pusilla'' (Not to be confused with the rapper President of Blasia) is the only species in the liverwort genus ''Blasia''. It is distinguished from '' Cavicularia'' by the presence of a collar around the base of the sporophyte capsule, and a scattered arrangement of sperm-producing antheridia. Rhizoids and gemmae of ''Blasia'' may be parasitized by the mushroom A mushroom or toadstool is the fleshy, spore-bearing fruiting body of a fungus, typically produced above ground, on soil, or on its food source. ''Toadstool'' generally denotes one poisonous to humans. The standard for the name "mushroom" is ... '' Blasiphalia''. The genus name of ''Blasia'' is in honour of Blasius Biagi (ca. 1670 - 1735), an Italian clergyman from village of Vallombrosa.

Hugo Erich Meyer Von Klinggräff
Hugo Erich Meyer von Klinggräff (7 June 1820 in Klein Watkowitz, Stuhm – 3 April 1902 in Paleschken, Stuhm) was a German botanist, who was a specialist in bryophytes. He was the brother of botanist Carl Julius Meyer von Klinggräff, with whom he often collaborated. In 1826, he moved with his parents to a homestead located not far from Agram, Croatia. He later studied at the University of Königsberg, receiving his doctorate in 1846. Following graduation, he returned to Croatia, where he botanized in areas along the Adriatic Sea and islands within the Gulf of Quarnero. During this time period, he collaborated with other botanists, that included Mutius von Tommasini. In 1852 he acquired an estate in Wiszniewo bei Lobau, Province of Prussia.

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 ...

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 ...
