Lady Fern
''Athyrium'' (lady-fern) is a genus of about 180 species of terrestrial ferns, with a cosmopolitan distribution. It is placed in the family Athyriaceae, in the order Polypodiales. Its genus name is from Greek '' a-'' ('without') and Latinized Greek ''thyreos'' ('shield'), describing its inconspicuous indusium (sorus' covering). The common name "lady fern" refers in particular to the common lady fern, ''Athyrium filix-femina''.Entry "lady fern", ''New Oxford American Dictionary 3rd edition'' (2010) by Oxford University Press, Inc. ''Athyrium'' species are used as food plants by the larvae of some Lepidoptera species including the small angle shades and ''Sthenopis auratus ''Sthenopis pretiosus'', the gold-spotted ghost moth, is a species of moth of the family Hepialidae.

Wissahickon Schist
The Wissahickon Formation is a mapped bedrock unit in Pennsylvania, New Jersey, and Delaware. It is named for the Wissahickon gorge in Fairmount Park, Philadelphia. In Maryland formations, the term "Wissahickon" is no longer used. Rocks in this classification have since been divided into several units, such as Lower Pelitic Schist and Prettyboy Schist. Description The Wissahickon is described as a pelitic schist and gneiss with interlayers of quartzite. Color is highly variable as is the mineralogy.Blackmer, G.C., (2005). Preliminary Bedrock Geologic Map of a Portion of the Wilmington 30- by 60-Minute Quadrangle, Southeastern Pennsylvania. Pennsylvania Geologic Survey, Open-File Report OFBM-05-01.0. A general description for the unit is a silver to brown garnet mica-schist. Metamorphic grade The highly variable nature of this rock type is also why the metamorphic grade is also complex. The existence of the minerals biotite, garnet, staurolite, and kyanite all imply a low-inter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smilax
''Smilax'' is a genus of about 300–350 species, found in the tropics and subtropics worldwide. In China for example about 80 are found (39 of which are endemic), while there are 20 in North America north of Mexico. They are climbing flowering plants, many of which are woody and/or thorny, in the monocotyledon family Smilacaceae, native throughout the tropical and subtropical regions of the world. Common names include ''catbriers'', ''greenbriers'', ''prickly-ivys'' and ''smilaxes''. ''Sarsaparilla'' (also zarzaparrilla, sarsparilla) is a name used specifically for the Jamaican '' S. ornata'' as well as a catch-all term in particular for American species. Occasionally, the non-woody species such as the smooth herbaceous greenbrier (''S. herbacea'') are separated as genus ''Nemexia''; they are commonly known by the rather ambiguous name ''carrion flowers''. Greenbriers get their scientific name from the Greek myth of Crocus and the nymph Smilax. Though this myth has numerous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Polypody
''Polypodium'' is a genus of ferns in the family Polypodiaceae, subfamily Polypodioideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). The genus is widely distributed throughout the world, with the highest species diversity in the tropics. The name is derived from Ancient Greek ''poly'' (πολύ) "many" + ''podion'' (πόδιον) "little foot", on account of the foot-like appearance of the rhizome and its branches. They are commonly called polypodies or rockcap ferns, but for many species unique vernacular names exist. They are terrestrial or epiphytic ferns, with a creeping, densely hairy or scaly rhizome bearing fronds at intervals along its length. The species differ in size and general appearance and in the character of the fronds, which are evergreen, persisting for 1–2 years, pinnate or pinnatifid (rarely simple entire), and from 10–80 cm or more long. The sori or groups of spore-cases (sporangia) are borne on the back of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chestnut Oak
''Quercus montana'', the chestnut oak, is a species of oak in the white oak group, ''Quercus'' sect. ''Quercus''. It is native to the eastern United States, where it is one of the most important ridgetop trees from southern Maine southwest to central Mississippi, with an outlying northwestern population in southern Michigan. It is also sometimes called rock oak because of its presence in montane and other rocky habitats. Description As a consequence of its dry habitat and ridgetop exposure, the chestnut oak is not usually a large tree, typically growing to tall; specimens growing in better conditions can grow up to tall. They tend to have a similar spread of . A 10-year-old sapling grown in full sun will stand about tall. This species is often an important canopy species in an oak-heath forest. It is readily identified by its massively-ridged dark gray-brown bark, the thickest of any eastern North American oak. The leaves are long and broad, shallowly lobed with 10– ...

Beech
Beech (''Fagus'') is a genus of deciduous trees in the family Fagaceae, native to temperate Europe, Asia, and North America. Recent classifications recognize 10 to 13 species in two distinct subgenera, ''Engleriana'' and ''Fagus''. The ''Engleriana'' subgenus is found only in East Asia, distinctive for its low branches, often made up of several major trunks with yellowish bark. The better known ''Fagus'' subgenus beeches are high-branching with tall, stout trunks and smooth silver-grey bark. The European beech (''Fagus sylvatica'') is the most commonly cultivated. Beeches are monoecious, bearing both male and female flowers on the same plant. The small flowers are unisexual, the female flowers borne in pairs, the male flowers wind-pollinating catkins. They are produced in spring shortly after the new leaves appear. The fruit of the beech tree, known as beechnuts or mast, is found in small burrs that drop from the tree in autumn. They are small, roughly triangular, and edible, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tulip Tree
''Liriodendron'' () is a genus of two species of characteristically large trees, deciduous over most of their populations, in the magnolia family (Magnoliaceae). These trees are widely known by the common name tulip tree or tuliptree for their large flowers superficially resembling tulips. It is sometimes referred to as tulip poplar or yellow poplar, and the wood simply as "poplar", although not closely related to the true poplars. Other common names include canoewood, saddle-leaf tree, and white wood. The two extant species are ''Liriodendron tulipifera'', native to eastern North America and ''Liriodendron chinense'', native to China and Vietnam. Both species often grow to great size, the North American species may reach as much as in height. The North American species is commonly used horticulturally, the Chinese species is increasing in cultivation, and hybrids have been produced between these two allopatrically distributed species. Various extinct species of ''Liriode ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
