Serpentine Ridge Nature Preserve
The Serpentine Ridge Nature Preserve is a 40 acres woodland in the North Shore of Staten Island between Howard Avenue at the top of the ridge and Van Duzer Street at the bottom of the hill. The Serpentine Ridge plays an important part in Staten Island's ecosystem and biodiversity and maintains significant geological features. The Serpentine Ridge is a steep terrain on the east shore of the island within the Grymes Hill and Silver Lake neighborhoods of Staten Island. The area is notable for its variety of ecosystems including wooded hillsides, glacial sinkholes, and bare serpentine rock. The area is part of Staten Island's Special Hillsides Preservation District. The district was established to preserve the hilly terrain and unique natural features of the region, by reducing hillside erosion, landslides, and excessive storm-water runoff. Most of its land remains in a natural state, thus the area is covered with native vegetation. The Serpentine Art and Nature Commons owns approximate ...

State Line Serpentine Barrens
State Line Serpentine Barrens is a tract of serpentine barrens in Pennsylvania and Maryland in the eastern United States. The protected area is actually an assemblage of six tracts owned by a combination of the Nature Conservancy, the State of Pennsylvania, two counties, a township, and private owners.

Serpentine Soil
Serpentine soil is an uncommon soil type produced by weathered ultramafic rock such as peridotite and its metamorphic derivatives such as serpentinite. More precisely, serpentine soil contains minerals of the serpentine subgroup, especially antigorite, lizardite, and chrysotile or white asbestos, all of which are commonly found in ultramafic rocks. The term "serpentine" is commonly used to refer to both the soil type and the mineral group which forms its parent materials. Serpentine soils exhibit distinct chemical and physical properties and are generally regarded as poor soils for agriculture. The soil is often reddish, brown, or gray in color due to its high iron and low organic content. Geologically, areas with serpentine bedrock are characteristically steep, rocky, and vulnerable to erosion, which causes many serpentine soils to be rather shallow. The shallow soils and sparse vegetation lead to elevated soil temperatures and dry conditions. Due to their ultramafic origin, ser ...

Isotria Verticillata
''Isotria verticillata'', commonly known as the large whorled pogonia and purple fiveleaf orchid, is an orchid species native to eastern North America. Distribution The orchid's native range is across the Eastern United States in the Appalachian Mountains, the central and eastern Great Lakes region, and elsewhere from Maine south to Florida, and westward from Michigan south to Texas. It is also native to Ontario, Canada. It grows in acidic soils in forests and in peat bogs. Description ''Isotria verticillata'' is a terrestrial orchid spreading by underground rhizome In botany and dendrology, a rhizome (; , ) is a modified subterranean plant stem that sends out roots and shoots from its nodes. Rhizomes are also called creeping rootstalks or just rootstalks. Rhizomes develop from axillary buds and grow hori ...s. Its leaves are green above, waxy and a bit whitened below. The flowers are yellowish-green, up to 110 mm (4.3 inches) across. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adiantum Pedatum
''Adiantum pedatum'', the northern maidenhair fern or five-fingered fern, is a species of fern in the family Pteridaceae, native to moist forests in eastern North America. Like other ferns in the genus, the name maidenhair refers to the slender, shining black stipes. Description ''A. pedatum'' grows tall, and is deciduous. Taxonomy ''Adiantum pedatum'' was described by Linnaeus in ''Species Plantarum'' in 1753 (the official starting point of modern botanical nomenclature). He referred to earlier descriptions, all based on material from eastern North America. Linnaeus' own herbarium contains one specimen, collected by Pehr Kalm. Specimens collected in Unalaska and Kodiak Island by Chamisso and Langsdorf were referred to as ''Adiantum boreale'' by Presl in 1836, although he did not provide a species description to accompany the name. Ruprecht, in 1845, called the Alaskan material ''A. pedatum'' var. ''aleuticum'', and created var. ''kamtschaticum'' for mater ...

Deparia Acrostichoides
''Deparia acrostichoides'', commonly called silvery glade fern or silvery spleenwort, is a perennial species of fern. Its range include much of the eastern United States and Canada, from Ontario to Nova Scotia, and Georgia to Louisiana and eastern Asia in China, Russia, Japan and Korea. The name silvery comes from the fact that the indusia on the underside of the leaf have a silver color when the sori are close to ripening. Description Silvery spleenwort has pinnately divided yellowish green leaves arising from a stout, green, slightly brown hairy and scaly stem. The stem is typically grooved on the upper side, much shorter than the leaf blade and darker colored near its base, being dark red or brown, as the stem reaches the leaflets it becomes a pale green color. The leaves are broadest in the middle with a long pointed tip and tapering base with the lowest pair of leaflets generally pointing downward. The tapering and downward pointed bottom leaves are a diagnostic characteri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cystopteris Fragilis
''Cystopteris fragilis'' is a species of fern known by the common names brittle bladder-fern and common fragile fern. It can be found worldwide, generally in shady, moist areas. The leaves are up to 30 or 40 centimeters long and are borne on fleshy Petiole (botany), petioles with few or no long hairs.

Sanguinaria Canadensis
''Sanguinaria canadensis'', bloodroot, is a perennial, herbaceous flowering plant native to eastern North America. It is the only species in the genus ''Sanguinaria'', included in the poppy family Papaveraceae, and is most closely related to ''Eomecon'' of eastern Asia. ''Sanguinaria canadensis'' is sometimes known as Canada puccoon, bloodwort, redroot, red puccoon, and black paste. Plants are variable in leaf and flower shape, and have been separated as a different subspecies due to these variable shapes, indicating a highly variable species. In bloodroot, the juice is red and poisonous. Products made from sanguinaria extracts, such as black salve, are escharotic and can cause permanent disfiguring scarring. Although preliminary studies have suggested that sanguinaria may have potential applications in cancer therapy, clinical studies are lacking, and its use is not recommended. Description Bloodroot grows from tall. It has one large basal leaf, up to across, with five t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhus Aromatica
''Rhus aromatica'', the fragrant sumac, is a deciduous shrub in the family Anacardiaceae native to North America.(1) (2) It is found in southern Canada (Alberta to Quebec) and nearly all of the lower 48 states except peninsular Florida. Fragrant sumac is a woody plant with a rounded form that grows to around to tall and to wide. The plant develops yellow flowers in clusters on short lateral shoots in March through May. The flower is a small, dense inflorescence that usually opens before the plant's leaves do. The species is polygamodioecious (mostly dioecious, primarily bearing flowers of only one sex, but with either a few flowers of the opposite sex or a few bisexual flowers on the same plant). Male (staminate) flowers develop in yellowish catkins, while female (pistillate) flowers develop in short bright yellow panicles at the ends of branches. Pollinated flowers develop clusters of to hairy red drupes containing a single nutlet during June through August. The fru ...
