Hepatica Doda
''Hepatica'' (hepatica, liverleaf, or liverwort) is a genus of herbaceous perennials in the buttercup family, native to central and northern Europe, Asia and eastern North America. Some botanists include ''Hepatica'' within a wider interpretation of '' Anemone''. Description Bisexual flowers with pink, purple, blue, or white sepals and three green bracts appear singly on hairy stems from late winter to spring. Butterflies, moths, bees, flies and beetles are known pollinators. The leaves are basal, leathery, and usually three-lobed, remaining over winter. Taxonomy ''Hepatica'' was described by the English botanist Philip Miller in 1754. It was proposed as a subgenus of '' Anemone'' in 1836, but later segregated into genus ''Hepatica''. Taxa , Kew's Plants of the World Online (POWO) accepts 7 species and one hybrid in the genus ''Hepatica'': One infraspecific taxon is also recognized by POWO: * ''Hepatica nobilis'' var. ''japonica'' ** Synony ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
