Cautleya
''Cautleya'' is a small genus of perennial plants of the family Zingiberaceae (the ginger family), found in the eastern Himalayas through to China and Vietnam. It consists of two species of high-altitude tropical and temperate plants, native to cool forest areas – an unusual habitat for members of the Zingiberaceae. They are grown as ornamental flowering plants. Description ''Cautleya'' species grow from short rhizomes which have thick, fleshy roots. They have "pseudostems" formed by the tightly wrapped basal sheaths of their leaves. Depending on the species, the pseudostems may be high. Individual leaves consist of a sheath and a blade. At the junction of the sheath and blade, there is a stalk ( petiole), which may be very short or absent. The plants die back in the winter with shoots appearing again in spring. The yellow or orange flowers appear in the summer and are grouped into a spike (inflorescence). Each flower is surrounded by a persistent coloured bract. The sepals a ...

Cautleya Gracilis
''Cautleya gracilis'' is a perennial herbaceous plant in the family Zingiberaceae (the gingers). It is found in the Himalayas through to south China and Vietnam. It is cultivated as an ornamental garden plant, hardy to a few degrees of frost. Description What appear to be stems in ''Cautleya'' species are actually "pseudostems" formed by the tightly wrapped bases or sheaths of the leaves. In ''C. gracilis'', the pseudostems are tall, with some purely sheathing leaves at the base. Other leaves also have blades, free from the pseudostem, long by wide. The inflorescence is a spike, with typically 2–10 loosely spaced flowers in ''C. gracilis'' var. ''gracilis'' and 15–20 more tightly spaced flowers making a compact "head" in ''C. gracilis'' var. ''robusta''. Each yellow or orange flower has a complex structure. A green bract surrounds the sepals, which are largely fused, forming a tubular calyx, split along one side, which is longer than the bract, being long ...

Cautleya Spicata
''Cautleya spicata'' is a perennial herbaceous plant in the family Zingiberaceae (the gingers). It is found in the Himalayas through to China (Yunnan). It is cultivated as an ornamental garden plant, hardy to a few degrees of frost. Description What appear to be stems in ''Cautleya'' species are actually "pseudostems" formed by the tightly wrapped bases or sheaths of the leaves. In ''Cautleya spicata'', the pseudostems are tall. There are 4–7 leaves with a stalk ( petiole) long between the sheath that forms part of the pseudostem and the blade which is free. The leaf blades are long by wide. The inflorescence appears in July in the native habitat of the species and takes the form of a dense spike about long. Each flower has a complex structure. A red bract surrounds the sepals, which are largely fused, forming a tubular calyx, split along one side. The calyx is shorter than the bract, being long. Inside the calyx, the three petals are fused at the base to form a tube a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roscoea
''Roscoea'' is a genus of perennial plants of the family (biology), family Zingiberaceae (the ginger family). Most members of the family are tropical, whereas ''Roscoea'' species are native to mountainous regions of the Himalayas, China and its southern neighbours. ''Roscoea'' flowers superficially resemble orchids, although they are not related. The flowers of ''Roscoea'' have a complicated structure, in which some of the showy coloured parts are not formed by petals, but by staminodes, sterile stamens which have evolved to become like petals. Some species are grown as ornamental plants in gardens. Description ''Roscoea'' is found from Kashmir through the Himalayas to Vietnam, extending northwards into China. There are up to 22 recognized species, of which 8 are endemic to China. Typically they grow in grassland, in Scree, screes or on the edges of deciduous woodland at heights of , coming into growth at the start of the monsoon season. Species of ''Roscoea'' are small perenni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proby Cautley
Sir Proby Thomas Cautley, KCB (3 January 1802 – 25 January 1871), English engineer and palaeontologist, born in Stratford St Mary, Suffolk, is best known for conceiving and supervising the construction of the Ganges canal during East India Company rule in India. The canal stretches some 350 miles between its headworks at Haridwar and, after bifurcation near Aligarh, its confluences with the Ganges river mainstem in Kanpur and the Yamuna river in Etawah.Stone (2002) p.18 At the time of completion, it had the greatest discharge of any irrigation canal in the world. Proby Cautley was educated at Charterhouse School (1813–18), followed by the East India Company's Military Seminary at Addiscombe (1818–19). After less than a year there, he was commissioned second lieutenant and dispatched to India, joining the Bengal Presidency artillery in Calcutta. In 1825, he assisted Captain Robert Smith, the engineer in charge of constructing the Eastern Yamuna canal, also called ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zingiberaceae

Aril
An aril (pronounced ), also called an arillus, is a specialized outgrowth from a seed that partly or completely covers the seed. An arillode or false aril is sometimes distinguished: whereas an aril grows from the attachment point of the seed to the ovary (from the funiculus or '' hilum''), an arillode forms from a different point on the seed coat. The term "aril" is sometimes applied to any fleshy appendage of the seed in flowering plants, such as the mace of the nutmeg seed. Arils and arillodes are often edible enticements that encourage animals to transport the seed, thereby assisting in seed dispersal. Pseudarils are aril-like structures commonly found on the pyrenes of Burseraceae species that develop from the mesocarp of the ovary. The fleshy, edible pericarp splits neatly in two halves, then falling away or being eaten to reveal a brightly coloured pseudaril around the black seed. The aril may create a fruit-like structure, called (among other names) a ''false fruit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bract
In botany, a bract is a modified or specialized leaf, especially one associated with a reproductive structure such as a flower, inflorescence axis or cone scale. Bracts are usually different from foliage leaves. They may be smaller, larger, or of a different color, shape, or texture. Typically, they also look different from the parts of the flower, such as the petals or sepals. A plant having bracts is referred to as bracteate or bracteolate, while one that lacks them is referred to as ebracteate and ebracteolate, without bracts. Variants Some bracts are brightly-coloured and serve the function of attracting pollinators, either together with the perianth or instead of it. Examples of this type of bract include those of ''Euphorbia pulcherrima'' (poinsettia) and ''Bougainvillea'': both of these have large colourful bracts surrounding much smaller, less colourful flowers. In grasses, each floret (flower) is enclosed in a pair of papery bracts, called the lemma (lower bract) and p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hedychium
''Hedychium'' is a genus of flowering plants in the ginger family Zingiberaceae, native to lightly wooded habitats in Asia. There are approximately 70-80 known species, native to India, Southeast Asia, and Madagascar. Some species have become widely naturalized in other lands, and considered invasive in some places. The genus name ''Hedychium'' is derived from two ancient Greek words, meaning "sweet" and meaning "snow". This refers to the fragrant white flower of the type species '' H. coronarium''. Common names include garland flower, ginger lily, and kahili ginger. Members of the genus ''Hedychium'' are rhizomatous perennials, commonly growing tall. Some species are cultivated for their exotic foliage and fragrant spikes of flowers in shades of white, yellow and orange. Numerous cultivars have been developed for garden use, of which 'Tara' has gained the Royal Horticultural Society's Award of Garden Merit. Though reasonably hardy down to , it requires a sheltered position a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Molecular Phylogenetics
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.
