Stenia Pastorellii
:''The grass moth genus ''Stenia'' is probably a junior synonym of '' Dolicharthria''; see there. ''Stenia'' is a genus in the orchid family (Orchidaceae). It was established by John Lindley in 1837. These epiphytic plants occur in warm, humid habitats of Trinidad and the Amazonian slope of the northern Andean region in South America. This genus as a rule lacks pseudobulbs and consequently produces tufted fan-like growths of fairly erect narrow, short leaves, and conforms to the sympodial method of growth. ''Stenia'' plants produce a short, creeping or erect, single-flowered inflorescences, growing laterally. The flowers are medium-sized, with equal petals and sepals. All members of this genus have their flowers dominated by the large, shoe-like, concave labellum (lip) with a disc-like, toothed crest. The flowers have four elongate pollinia, with the upper pollinia long and narrow. They occur at any time of the year, though slightly more concentrated during summer in culti ...

Grass Moth
The Crambidae are the grass moth family of lepidopterans. They are variable in appearance, the nominal subfamily Crambinae (grass moths) taking up closely folded postures on grass stems where they are inconspicuous, while other subfamilies include brightly coloured and patterned insects which rest in wing-spread attitudes. In many classifications, the Crambidae have been treated as a subfamily of the Pyralidae or snout-moths. The principal difference is a structure in the tympanal organs called the praecinctorium, which joins two tympanic membranes in the Crambidae, and is absent from the Pyralidae. The latest review by Munroe and Solis, in Kristensen (1999), retains the Crambidae as a full family. The family currently comprises 15 subfamilies with altogether 10,347 species in over 1,000 genera.

Flower
A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Angiospermae). The biological function of a flower is to facilitate reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) resulting from cross-pollination or allow selfing (fusion of sperm and egg from the same flower) when self-pollination occurs. There are two types of pollination: self-pollination and cross-pollination. Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is when pollen is transferred from the anther of one flower to the stigma of another flower on a different individual of the same species. Self-pollination happens in flowers where the stamen and carpel mature at the same time, and are positi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pollinium
A pollinium (plural pollinia) is a coherent mass of pollen grains in a plant that are the product of only one anther, but are transferred, during pollination, as a single unit. This is regularly seen in plants such as orchids and many species of milkweeds (Asclepiadoideae). Usage of the term differs: in some orchids two masses of pollen are well attached to one another, but in other orchids there are two halves (with two separate viscidia) each of which is sometimes referred to as a pollinium. Most orchids have waxy pollinia. These are connected to one or two elongate stipes, which in turn are attached to a sticky viscidium, a disc-shaped structure that sticks to a visiting insect. Some orchid genera have mealy pollinia. These are tapering into a caudicle (stalk), attached to the viscidium. They extend into the middle section of the column. The pollinarium is a collective term that means either (1) the complete set of pollinia from all the anthers of a flower, as in Asclepiadoideae ...
