Rein Orchid
''Piperia'' is a former genus within the orchid family Orchidaceae that has since been subsumed under ''Platanthera''. These plants are known as rein orchids. They are native to western North America, especially California and the Pacific Northwest. This former genus has the following characteristics: (a) a bisexual perennial nongreen plant that grows from buried tubers; fruit capsule bearing numerous minute seeds; (c) pollen that is sticky, and which is removed as sessile anther sacs; and (d) stigma fused with its style into a column. There were a total of ten species in the genus ''Piperia'', which is named for American botanist Charles V. Piper. The genus members manifest generally cylindrical spikes or racemes. The subsurface architecture of these terrestrial wild orchids consists of a rhizome structure, from which emanate tubers. The rhizome extracts nutrients from fungal intermediates and may also store some of these nutrients. A basal rosette of leaves develops ...

Raceme
A raceme ( or ) or racemoid is an unbranched, indeterminate type of inflorescence bearing flowers having short floral stalks along the shoots that bear the flowers. The oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. Examples of racemes occur on mustard (genus ''Brassica'') and radish (genus ''Raphanus'') plants. Definition A ''raceme'' or ''racemoid'' is an unbranched, indeterminate type of inflorescence bearing pedicellate flowers (flowers having short floral stalks called ''pedicels'') along its axis. In botany, an ''axis'' means a shoot, in this case one bearing the flowers. In indeterminate inflorescence-like racemes, the oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. A plant that flowers on a showy raceme may have this reflected in its scientific name, e.g. the species ''Cimicifuga racemosa''. A compou ...

Platanthera Yadonii
''Platanthera yadonii'', also known as Yadon's piperia or Yadon's rein orchid, is an endangered orchid endemic to a narrow range of coastal habitat in northern Monterey County, California. In 1998 this plant was designated as an endangered species by the United States government, the major threat to its survival being continuing land development from an expanding human population and associated habitat loss. One of the habitats of Yadon's piperia, the Del Monte Forest near Monterey, California, is the subject of a federal lawsuit, based upon endangerment of this organism along with several other endangered species. This wildflower may lie dormant in a given year and not emerge above the soil surface from its tuberous substructure. After leafing out in the spring, it will produce flowers on erect spikes, each flower possessing both green and white petals. It prefers sandy soils, and subsists on nutrient extraction from intermediate fungal organisms. Description Along ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

They are pollinated Pollination is the transfer of pollen from an anther of a plant to the stigma of a plant, later enabling fertilisation and the production of seeds, most often by an animal or by wind. Pollinating agents can be animals such as insects, birds, ... by geometrid moths. Refer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
