Olacaceae
Olacaceae is a family of flowering plants in the order Santalales. They are woody plants, native throughout the tropical regions of the world. , the circumscription of the family varies; some sources maintain a broad family, others split it into seven segregate families. Taxonomy The 1998 APG system and the 2003 APG II system assign it to the order Santalales in the clade core eudicots. Prior to the advent of molecular data, the circumscription of the family Olacaceae varied widely between different authorities.Valéry Malécot and Daniel L. Nickrent. 2008. "Molecular Phylogenetic Relationships of Olacaceae and Related Santalales". ''Systematic Botany'' 33(1):97-106. Among these various classifications, about 30 genera were included in the family. 15 genera are recognized for Olacaceae by the Germplasm Resources Information Network. The phylogenetic investigation published in 2008 recovered seven clades that were well-supported by molecular and morphological characters, but ...

Santalales
The Santalales are an order (biology), order of flowering plants in the dicotyledons. Well-known members of the Santalales include Santalum, sandalwoods and the many species of mistletoes. The order has a cosmopolitan distribution, but is heavily concentrated in tropical and subtropical regions. It derives its name from its type genus, ''Santalum'' (sandalwood). Overview Many of the members of the order are parasitic plants, mostly hemiparasites, able to produce sugars through photosynthesis, but tapping the stems or roots of other plants to obtain water and minerals; some (e.g. ''Arceuthobium'') are obligate parasites, have low concentrations of chlorophyll within their shoots (1/5 to 1/10 of that found in their host's foliage), and derive the majority of their sustenance from their hosts' vascular tissues (water, micronutrient, micro- and macronutrients, and sucrose). Most have seeds without testa (botany), testae (seed coats), which is unusual for flowering plants. Classif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schoepfia
''Schoepfia'' is a genus of small hemiparasitic trees, flowering plants belonging to the family Schoepfiaceae. The genus has long been placed in the Olacaceae family. Description Plants in this genus are small trees or shrubs which exhibit heterostyly - individuals can have both often cylindrical brachystylous (short styled) flowers and somewhat bell-shaped dolichostylous (longer styled) flowers. In most plants where heterostyly occurs, there is a sexual differentiation between flower types, the brachystylous flowers being functionally male, or one type of flower is cleistogamous or self-fertile. In ''Schoepfia'' species both flowers are bisexual and can form fruit, the reason for two flower forms is mysterious. The flowers are fragrant and small. They arise from a short Peduncle (botany), peduncle which grows from the leaf axils of a stem. The peduncle is subtended by persistent, imbricate perular bracts. The flower is subtended by a three-lobed epicalyx, it is composed of a b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ochanostachys
''Ochanostachys'' is a genus of flowering plants with a single species, ''Ochanostachys amentacea''. The genus is placed in the family Olacaceae in the APG IV system and by sources that use it.

Harmandia Mekongensis
''Harmandia mekongensis'' is a species of flowering plants. It is the only species in the monotypic genus of ''Harmandia''. In the APG IV system, the genus is placed in the family Olacaceae. Other sources place it in the segregate family Aptandraceae. Its native range is Indo-China to Sumatra, Malay Peninsula and Borneo in western Malesia. Taxonomy The genus name of ''Harmandia'' is in honour of Jules Harmand (1845–1921), a French naval doctor and naturalist, who collected plants in south-east Asia, Japan and present-day Sri Lanka. The Latin specific epithet of ''mekongensis'' is named after the Mekong River from where the plant was collected. It was first described and published in Bull. Mens. Soc. Linn. Paris Vol.2 on page 770 in 1889. Description The tree grows to a height between 6 and 40 metres. Its bark is flaky comprising an outer pale layer and a whitish or yellowish inner layer, the wood is pale yellow. The oblong or lanceolate leaves with 5–9 cm long and ...

Malania
''Malania oleifera'' is a species of plant in the Olacaceae family, the only species in the genus ''Malania''. It is a medium-sized tree, tall, that is endemic to southern China where it can be found in Western Guangxi and South-Eastern Yunnan provinces. Known as "garlic-fruit tree" or ‘suantouguo’ (蒜头果) by local communities due to its garlic-shaped fruits, it is threatened by logging and habitat loss. Notable for its substantial phytochemical value, its seed has the highest-known proportion of nervonic acid (C24H46O2, PubChem CID: 5281120). Nervonic acid is an important component in myelin Myelin Sheath ( ) is a lipid-rich material that in most vertebrates surrounds the axons of neurons to insulate them and increase the rate at which electrical impulses (called action potentials) pass along the axon.
