Huperzia Subintegra
''Huperzia'' is a genus of lycophyte plants, sometimes known as the firmosses or fir clubmosses; the ''Flora of North America'' calls them gemma fir-mosses. This genus was originally included in the related genus ''Lycopodium'', from which it differs in having undifferentiated sporangial leaves, and the sporangia not formed into apical cones. The common name ''firmoss'', used for some of the north temperate species, refers to their superficial resemblance to branches of fir (''Abies''), a conifer. , two very different circumscriptions of the genus were in use. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), ''Huperzia'' is one of three genera in the subfamily Huperzioideae of the family Lycopodiaceae. Most species in the subfamily are placed in the genus ''Phlegmariurus''. ''Huperzia'' is left with about 25 species, although not all have been formally transferred to other genera. Other sources recognize only ''Huperzia'', which then has about 340 species. Mor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Jacob Bernhardi
Johann Jakob Bernhardi (1 September 1774, in Erfurt – 13 May 1850, in Erfurt) was a German doctor and botanist. Biography Johann J. Bernhardi studied Medicine and Botany at the University of Erfurt, and after graduation practiced medicine for a time in his native city. In 1799 he was named director of the botanical garden at ''Gartenstraße'', and in 1809 was appointed professor of botany, zoology, mineralogy and materia medica at the university. He served as director of the botanical garden until his death in 1850, being buried in the central avenue of this botanical garden. Throughout his life thanks to acquisitions and interchanges with other botanists, he assembled a considerable herbarium of 60,000 plants with specimens from North America, South America, Asia, and Africa. After his death this herbarium did not remain in Germany but due to the efforts of George Engelmann, who, in 1857, shortly after the death of Bernhardi bought the complete herbarium for the amount of 600 do ...

Type Species
In International_Code_of_Zoological_Nomenclature, zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological Type (biology), type wiktionary:en:specimen, specimen (or specimens). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the International Code of Nomenclature for algae, fungi, and plants, code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name with that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have suc ...

Huperzia Australiana
''Huperzia australiana'' is a species of small terrestrial plant, a firmoss, in the Lycopodiaceae (clubmoss) family. It is native to Australia and New Zealand. Distribution and habitat The plant occurs at sheltered sites in subalpine and subantarctic regions, in grasslands and around bogs, up to 2000 m above sea level. Description ''Huperzia australiana'' has decumbent stems with densely tufted, erect branches up to 300 mm long, usually branched 2 or 3 times. The leaves are crowded, appressed to spreading, 5–9 mm long, 0.5–1.5 mm wide in the middle and tapering to a point. It reproduces vegetatively through the often numerous small bulbils which form along the stem. The sporophylls are similar to the foliage leaves; no strobili are formed; the bright yellow, kidney-shaped sporangia are produced in the upper leaf axils. References australiana Australiana is anything pertaining to Australian culture, society, geography and ecology, especia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Huperzia Appalachiana
''Huperzia appalachiana'' is a species of clubmoss. Description The original description is:Stems tufted to shortly decumbent (), erect portions of stem tall. Stems appear to live for definite periods (about 10 years of spore production), then senesce and the entire plant dies. New stems produced by gemmae, which fall at base of older plant. Growth during juvenile period erect. Stems showing no annual constrictions. Mature portion of stem with markedly small leaves. Leaves ascending to spreading in juvenile portion, ascending to appressed in mature portion. Plants uniformly green to yellow-green. Adaxial leaf surfaces with large number of stomates (35-60 per half leaf). Leaf margin entire with occasional small papillae formed by marginal Range Restricted to acidic rock at high elevations along the lower Appalachians, and to northern latitudes elsewhere, generally near the Canadian border in Vermont, Maine, and Michigan, and up into the Canadian Shield. Habitat Acidic rock, oc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Phylloglossum
''Phylloglossum'', a genus in the clubmoss Family (biology), family Lycopodiaceae, is a small plant superficially resembling a tiny Poaceae, grass plant, growing with a rosette of slender leaf, leaves 2–5 cm long from an underground bulb-like root. It has a single central stem up to 5 cm tall bearing a spore-producing cone at the apex, and was previously classified variously in the family Lycopodiaceae or in its own family the Phylloglossaceae, but recent genetics, genetic evidence demonstrates it is most closely related to the genus ''Firmoss, Huperzia'' and is a sister clade to the genus ''Phlegmariurus'', which was formerly included in ''Huperzia''. Morphological characters, as well as molecular characters based on ''rbc''L data, support the close relationship of ''Phylloglossum'' to ''Huperzia''. Similarities in spore morphology, sporangial epidermis morphology, phytochemistry, and chromosome number indicate that ''Phylloglossum'' and ''Huperzia'' are closely rela ...
