Actephila Collinsiae
''Actephila'' is a genus of plants in the family Phyllanthaceae, first described as a genus in 1826. It is one of 8 genera in the tribe Poranthereae, and is most closely related to ''Leptopus''. The name of the genus is derived from two Greek words, ''akte'', "the seashore", and ''philos'', "loving". It refers to a coastal habitat.Umberto Quattrocchi. 2000. ''CRC World Dictionary of Plant Names'' volume I. CRC Press: Boca Raton; New York; Washington,DC;, USA. London, UK. (vol. I). (see ''External links'' below). ''Actephila'' consists of monoecious trees, shrubs, and subshrubs. The genus is not well understood and is in much need of revision. It is native to Southeast Asia, China, the Himalayas, Papuasia and northern Australia. ;Species ;Formerly included moved to other genera: ''Cleidion Excoecaria Pentabrachion Phyllanthus ''Phyllanthus'' is the largest genus in the plant family Phyllanthaceae.

Herbarium
A herbarium (plural: herbaria) is a collection of preserved plant specimens and associated data used for scientific study. The specimens may be whole plants or plant parts; these will usually be in dried form mounted on a sheet of paper (called '' exsiccatum'', plur. ''exsiccata'') but, depending upon the material, may also be stored in boxes or kept in alcohol or other preservative. The specimens in a herbarium are often used as reference material in describing plant taxa; some specimens may be types, some may be specimens distributed in series called exsiccatae. The same term is often used in mycology to describe an equivalent collection of preserved fungi, otherwise known as a fungarium. A xylarium is a herbarium specialising in specimens of wood. The term hortorium (as in the Liberty Hyde Bailey Hortorium) has occasionally been applied to a herbarium specialising in preserving material of horticultural origin. History The making of herbaria is an ancient phenome ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monoecious
Monoecy (; adj. monoecious ) is a sexual system in seed plants where separate male and female cones or flowers are present on the same plant. It is a monomorphic sexual system alongside gynomonoecy, andromonoecy and trimonoecy. Monoecy is connected to anemophily. It can prevent self-pollination in an individual flower but cannot prevent self-pollination between male and female flowers on the same plant. Monoecy in angiosperms has been of interest for evolutionary biologists since Charles Darwin. Terminology Monoecious comes from the Greek words for one house. History The term monoecy was first introduced in 1735 by Carl Linnaeus. Darwin noted that the flowers of monoecious species sometimes showed traces of the opposite sex function. Monoecious hemp was first reported in 1929. Occurrence Monoecy is most common in temperate climates and is often associated with inefficient pollinators or wind-pollinated plants. It may be beneficial to reducing pollen-stigma i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
