Octolepidoideae
Octolepidoideae is a subfamily and one of the earliest branches of the Thymelaeaceae family. This species inherited multiple morphological character states from its ancestor, Thymelaeaceae. The calyx of a typical octolepidoideae is 5-merous. Researchers have found the species to contain 4-merous and 6-merous calyces, albeit they remain rarer. The pollen of most octolepidoideae are provided with small spinule Spinules are small spines or thorns (vertebral columns) that are part of biological and manmade structures. The word originates from the Latin word and is often used in botany and zoology. The presence or absence of spinules, and their shape, can ...s on the outer covering of their pollen grains.

Thymelaeaceae
The Thymelaeaceae are a cosmopolitan family of flowering plants composed of 50 genera (listed below) and 898 species.Zachary S. Rogers (2009 onwards)A World Checklist of Thymelaeaceae (version 1) Missouri Botanical Garden Website, St. Louis. It was established in 1789 by Antoine Laurent de Jussieu.Antoine Laurent de Jussieu ''Genera Plantarum'', page 76. Herrisant & Barrois, Paris. The Thymelaeaceae are mostly trees and shrubs, with a few vines and herbaceous plants. Description This is not intended as a full botanical description, but only as a few notes on some of the conspicuous or unusual traits of the family when ''Tepuianthus'' is excluded. The bark is usually shiny and fibrous. Attempts to break the stem often result in a strip of bark peeling down the side.Ernst Schmidt, Mervyn Lotter and Warren McCleland The number of stamens is usually once or twice the number of calyx lobes. If twice, then they often occur in two well separated series. Exceptions include ''Gonystylu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gonystylus Miquelianus
''Gonystylus'' is a southeast Asian genus of about 30 species of hardwood trees also known as ramin, melawis (Malay) and ramin telur (Sarawak). Description Ramin is native to Malaysia, Singapore, Indonesia, Brunei, the Philippines, and Papua New Guinea, with the highest species diversity on Borneo. It is related to '' Arnhemia'', ''Deltaria'', ''Lethedon'' and ''Solmsia''. Ramin is a medium-sized tree, attaining a height of about 24 m (80 ft) with a straight, clear (branch-free), unbuttressed bole about 18 m (60 ft) long and 60 cm (2 ft) in diameter. The trees are slow-growing, occurring mainly in swamp forests. Species ''The Plant List'' recognises 32 accepted species: * ''Gonystylus acuminatus'' * ''Gonystylus affinis'' * ''Gonystylus areolatus'' * ''Gonystylus augescens'' * ''Gonystylus bancanus'' * ''Gonystylus borneensis'' * ''Gonystylus brunnescens'' * ''Gonystylus calophylloides'' * '' Gonystylus calophyllus'' * '' Gonys ...

Subfamily (biology)
In biological classification, a subfamily (Latin: ', plural ') is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus. Standard nomenclature rules end subfamily botanical names with "-oideae", and zoological names with "-inae". See also * International Code of Nomenclature for algae, fungi, and plants * International Code of Zoological Nomenclature * Rank (botany) * Rank (zoology) In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system consists of species, genus, family, order, class, phylum, kingdom, domain. While olde ... Sources {{biology-stub ...

Calyx (botany)
A sepal () is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom., p. 106 The term ''sepalum'' was coined by Noël Martin Joseph de Necker in 1790, and derived . Collectively the sepals are called the calyx (plural calyces), the outermost whorl of parts that form a flower. The word ''calyx'' was adopted from the Latin ,Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 not to be confused with 'cup, goblet'. ''Calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet', and the words have been used interchangeably in botanical Latin. After flowering, most plants have no more use for the calyx which withers or becomes vestigial. Some plants retain a thorny calyx, either dried or live, as ...

Spinule
Spinules are small spines or thorns (vertebral columns) that are part of biological and manmade structures. The word originates from the Latin word and is often used in botany and zoology. The presence or absence of spinules, and their shape, can differentiate species and is used to describe and distinguish anatomical features. The development of spinules in the eye may be affected by dopamine, circadian rhythms, and exposure to light or dark environments, according to a studies of controlling mechanisms. liquid-crystal displays (LCDs) can employ an anisotropic Anisotropy () is the property of a material which allows it to change or assume different properties in different directions, as opposed to isotropy.
