Actaea Podocarpa
''Actaea podocarpa'', the mountain bugbane or mountain black-cohosh, is a species of flowering plant in the buttercup family. It is native to the eastern United States, where it is found in the Appalachian Mountains The Appalachian Mountains, often called the Appalachians, (french: Appalaches), are a system of mountains in eastern to northeastern North America. The Appalachians first formed roughly 480 million years ago during the Ordovician Period. They ..., with a disjunct population in Illinois. It is found in rich, mesic forests often in boulder-strewn coves. ''Actaea podocarpa'' is a large perennial herb. It is one of the later flowering of the eastern ''Actaea'', producing white flowers in summer through fall. References podocarpa Flora of the United States {{Ranunculales-stub ...

Ranunculaceae
Ranunculaceae (buttercup or crowfoot family; Latin "little frog", from "frog") is a family of over 2,000 known species of flowering plants in 43 genera, distributed worldwide. The largest genera are ''Ranunculus'' (600 species), ''Delphinium'' (365), ''Thalictrum'' (330), ''Clematis'' (325), and ''Aconitum'' (300). Description Ranunculaceae are mostly herbaceous annuals or perennials, but some are woody climbers (such as ''Clematis'') or shrubs (e.g. ''Xanthorhiza''). Most members of the family have bisexual flowers which can be showy or inconspicuous. Flowers are solitary, but are also found aggregated in cymes, panicles, or spikes. The flowers are usually radially symmetrical but are also found to be bilaterally symmetrical in the genera ''Aconitum'' and ''Delphinium''. The sepals, petals, stamens and carpels are all generally free (not fused), the outer flower segments typically number four or five. The outer stamens may be modified to produce only nectar, as in Aqui ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Appalachian Mountains
The Appalachian Mountains, often called the Appalachians, (french: Appalaches), are a system of mountains in eastern to northeastern North America. The Appalachians first formed roughly 480 million years ago during the Ordovician Period. They once reached elevations similar to those of the Alps and the Rocky Mountains before experiencing natural erosion. The Appalachian chain is a barrier to east–west travel, as it forms a series of alternating ridgelines and valleys oriented in opposition to most highways and railroads running east–west. Definitions vary on the precise boundaries of the Appalachians. The United States Geological Survey (USGS) defines the ''Appalachian Highlands'' physiographic division as consisting of 13 provinces: the Atlantic Coast Uplands, Eastern Newfoundland Atlantic, Maritime Acadian Highlands, Maritime Plain, Notre Dame and Mégantic Mountains, Western Newfoundland Mountains, Piedmont, Blue Ridge, Valley and Ridge, St. Lawrence Valley, Appalac ...

Actaea (plant)
''Actaea'', commonly called baneberry, bugbane and cohosh, is a genus of flowering plants of the family Ranunculaceae, native to subtropical, temperate and subarctic regions of Europe, Asia and North America. Taxonomy The genus was redefined to include ''Cimicifuga'' and ''Souliea'' in the 1990s (Compton et al. 1998, Compton & Culham 2002, Gao et al. 2006, RHS Plant Finder, 2007) based on combined evidence from DNA sequence data, similarity in biochemical constituents and on morphology returning it to the original Linnean concept of the genus. The number of species in ''Actaea'' is to 25–30 using this concept. Other botanists (e.g., Hoffman 1999, Wang et al. 1999, Lee & Park 2004, Wang et al. 2009) reject this merger because only one group (''Actaea'') have fleshy fruit while the remainder have dry fruit. However, this narrower generic concept works for only a single morphological character and other characters such as number of carpels moves the generic boundary. The genus ...
