Thunbergia Wightiana
''Thunbergia bicolor'', also known as the bicolour clock vine, is a species of flowering plant within the family Acanthaceae. Description Leaves The leaves of ''Thunbergia bicolor'' are paired at a node and borne opposite to each other. They are oval to triangular in shape, with a pointed tip and a base that can be either truncate or rounded. The leaves are palmately veined and the veins radiate out from a central point like the fingers of a hand. The leaf margins are crenate, exhibiting shallow rounded teeth along the edges. Flowers The flowers of this ''Thunbergia bicolor'' are borne in hanging clusters known as axillary pendent racemes. These clusters are positioned in the leaf axils, where the leaf meets the stem. The flowers are accompanied by conspicuous bracts that are roughly 2-2.5 cm in diameter. These bracts have a cordate-orbicular shape, with the upper half displaying an orange-red coloration while the lower half is pale yellow. The calyx, which forms the oute ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acanthaceae
Acanthaceae is a family (the acanthus family) of dicotyledonous flowering plants containing almost 250 genera and about 2500 species. Most are tropical herbs, shrubs, or twining vines; some are epiphytes. Only a few species are distributed in temperate regions. The four main centres of distribution are Indonesia and Malaysia, Africa, Brazil, and Central America. Representatives of the family can be found in nearly every habitat, including dense or open forests, scrublands, wet fields and valleys, sea coast and marine areas, swamps, and mangrove forests. Description Plants in this family have simple, opposite, decussated leaves with entire (or sometimes toothed, lobed, or spiny) margins, and without stipules. The leaves may contain cystoliths, calcium carbonate concretions, seen as streaks on the surface. The flowers are perfect, zygomorphic to nearly actinomorphic, and arranged in an inflorescence that is either a spike, raceme, or cyme. Typically, a colorful bract subtends ea ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
India
India, officially the Republic of India (Hindi: ), is a country in South Asia. It is the seventh-largest country by area, the second-most populous country, and the most populous democracy in the world. Bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast, it shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the north; and Bangladesh and Myanmar to the east. In the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives; its Andaman and Nicobar Islands share a maritime border with Thailand, Myanmar, and Indonesia. Modern humans arrived on the Indian subcontinent from Africa no later than 55,000 years ago., "Y-Chromosome and Mt-DNA data support the colonization of South Asia by modern humans originating in Africa. ... Coalescence dates for most non-European populations average to between 73–55 ka.", "Modern human beings—''Homo sapiens''—originated in Africa. Then, int ...

South Western Ghats Montane Rain Forests
The South Western Ghats montane rain forests is an ecoregion in South India, covering the southern portion of the Western Ghats in Karnataka, Kerala and Tamil Nadu at elevations from . Annual rainfall in this ecoregion exceeds . Setting The ecoregion is the most species rich in peninsular India, and is home to numerous endemic species. It covers an area of . It is estimated that two-thirds of the original forests have been cleared, and only 3,200 square kilometers, or 15% of the intact area, is protected. The southern portion of the Western Ghats contains the highest peaks in the range, notably Anamudi in Kerala, at 2695 meters elevation. The Ghats intercept the moisture-laden monsoon winds off the Arabian Sea, and the average annual precipitation exceeds 2,800 mm. The northeast monsoon from October to November supplements the June to September southwest monsoon. The South Western Ghats are the wettest portion of peninsular India, and are surrounded by drier ecoregions to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thunbergia
''Thunbergia'' is a genus of flowering plants in the family Acanthaceae, native to tropical regions of Africa, Madagascar and southern Asia. ''Thunbergia'' species are vigorous annual or perennial vines and shrubs growing to 2–8 m tall. The generic name honours the Swedish naturalist Carl Peter Thunberg (1743-1828). Its members are known by various names, including thunbergias and clockvine. ''Thunbergia'' on its own usually refers to ''Thunbergia grandiflora'', while ''Thunbergia alata'' is often known as black-eyed Susan vine or just black-eyed Susan (not to be confused with other flowers called black-eyed Susan). Orange clockvine is the name of ''Thunbergia gregorii''. ''Thunbergias'' are frequent garden escapes, becoming invasive species; ''T. grandiflora'', ''T. fragrans'', and ''T. laurifolia'' are considered weeds in Australia. Selected species *''Thunbergia alata'' Bojer ex Sims *''Thunbergia annua'' Hochst. ex Nees *''Thunbergia atriplicifolia'' E.Mey. ex Nees *'' ...
