Johannes Jacobus Smith
Johannes Jacobus Smith (Antwerp 29 June 1867 – Oegstgeest 14 January 1947) (sometimes written as Joannes Jacobus Smith) was a Dutch botanist who, between years 1905 to 1924, crossed the islands of the Dutch East Indies (mainly Java), collecting specimens of plants and describing and cataloguing the flora of these islands. The standard botanical author abbreviation J.J.Sm. is applied to plants described by J.J. Smith. The description of the flowers of the western half of New Guinea (then a Dutch territory) is largely based on his work. He was, next to Rudolf Schlechter, the most prolific author on New Guinea orchids. He also described numerous plants from other families, such as Ericaceae and Euphorbiaceae. Biography Smith was born in Antwerp where his father worked in the postal department. The family moved to Utrecht in 1872 and to Amsterdam in 1875. He took an interest in growing plants and keeping animals. One of his secondary school teachers was Jan Costerus who advised hi ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (). The term angiosperm is derived from the Ancient Greek, Greek words (; 'container, vessel') and (; 'seed'), meaning that the seeds are enclosed within a fruit. The group was formerly called Magnoliophyta. Angiosperms are by far the most diverse group of Embryophyte, land plants with 64 Order (biology), orders, 416 Family (biology), families, approximately 13,000 known Genus, genera and 300,000 known species. They include all forbs (flowering plants without a woody Plant stem, stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. Angiosperms are distinguished from the other major seed plant clade, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orchidaceae
Orchids are plants that belong to the family (biology), family Orchidaceae (), a diverse and widespread group of flowering plants with blooms that are often colourful and fragrant. Orchids are cosmopolitan distribution, cosmopolitan plants that are found in almost every habitat (ecology), habitat on Earth except glaciers. The world's species richness, richest diversity of orchid genera and species is in the tropics. Orchidaceae is one of the two largest families of flowering plants, the other being the Asteraceae. It contains about 28,000 currently accepted species in 702 genera. The Orchidaceae family encompasses about 6–11% of all species of seed plants. The largest genera are ''Bulbophyllum'' (2,000 species), ''Epidendrum'' (1,500 species), ''Dendrobium'' (1,400 species) and ''Pleurothallis'' (1,000 species). It also includes ''Vanilla (genus), Vanilla'' (the genus of the Vanilla planifolia, vanilla plant), the type genus ''Orchis'', and many commonly cultivated plants s ...

Chroniochilus Ecalcaratus
''Chroniochilus'' is a genus of flowering plants from the orchid family, Orchidaceae. It contains 5 species, native to Yunnan, Thailand, Malaysia and Indonesia.

Stamen
The stamen (: stamina or stamens) is a part consisting of the male reproductive organs of a flower. Collectively, the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains sporangium, microsporangia. Most commonly, anthers are two-lobed (each lobe is termed a locule) and are attached to the filament either at the base or in the middle area of the anther. The sterile (i.e. nonreproductive) tissue between the lobes is called the Connective (botany), connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The size of anthers differs greatly, from a tiny fraction of a millimeter in ''Wolfia'' spp up to five inches (13 centimeters) in ''Canna iridiflora'' and ''Strelitzia nicolai''. The stamens in a flower ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vandeae Genera
The Vandeae is a large monophyly, monophyletic Tribe (biology), tribe within the family of orchids. Scope This tribe contains 1,700 - 2,000 species in more than 150 genera. Epiphytic These orchids are pantropical epiphytes and occur in tropical Asia, the Pacific Islands, Australia and Africa. Many of these orchids are horticulture, horticulturally important, especially ''Vanda'' and ''Phalaenopsis''. Subtribes This tribe is subdivided into four subtribes: *Subtribe Adrorhizinae *Subtribe Aeridinae (formerly, illegitimate subtribal name Sarcanthinae): largest subtribe with more than 1,000 species in 103 genera, including about 200 hybrid species; occurs mostly in Asia and Australia and with a few in Africa. They are distinguished from the other subtribes by having an entire rostellum, a relatively small Spur (biology), spur formed by the lip, and four (or two) pollinium, pollinia. *Subtribe Angraecinae Summerh.: about 400 species in 19 genera.
