Sphaerocarpales
Sphaerocarpales is an order of plants within the liverworts. Approximately twenty species are in this order which is sub-divided into four families: Monocarpaceae, Sphaerocarpaceae and Riellaceae, as well as the extinct family Naiaditaceae. The inclusion of the Naiaditaceae is uncertain, and the family has sometimes been assigned to the Calobryales.

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 ...

Approximately ten species are included in this family, most of them in the genus ''Sphaerocarpos ''Sphaerocarpos'' is a genus of plants known as bottle liverworts. There are eight or nine species in this genus. Classification ''Sphaerocarpos'' is one of two extant genera in the famly Sphaerocarpaceae.

Distribution The majority of species in the family occur along the western edge of the Americas, from Washington to central Chile. However, the type species for ''Sphaerocarpos'', ''S. michelii'', is native to Europe. The weedy species '' Sphaerocarpos texanus'' is distributed widely in fields and gardens of North America, western Europe, and Mediterranean Africa. It may have been introduced with soil brought with crops or garden plants imported from the Americas. Classification The group was recogni ...

Riella
''Riella'' is a genus in the liverwort family Riellaceae, and includes about eighteen species. Plants in the genus are small and grow submerged in shallow temporary pools. Although the genus is widely distributed in the Northern Hemisphere, locating populations is often difficult. Its occurrence is sporadic and local, and the tiny plants are ephemeral. The ornamented spores remain viable for several years, allowing the plants to survive annual drying of their habitat. The plants are easily grown in laboratory cultures. Description ''Riella'' plants are small, usually or less, and thalloid, with an appearance like an immature alga. The plant consists of an erect central axis ("stem") that is commonly forked, but only sparingly, and the plants are bright green. The stem bears a thin dorsal lamina or "wing", which being on only one side gives the plant an asymmetrical appearance. This lamina is ruffled or undulate. Early descriptions of the species '' Riella helicophylla'' o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Order (biology)
Order ( la, wikt:ordo#Latin, ordo) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between Family_(biology), family and Class_(biology), class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. Fo ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes 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 ...
