A cup-shaped staminate perianth with dorsal, fleshy, crestate appendages is present only in Endolepis dioica. |
|
Males produce only staminate flowers with stamens and no vestigial pistils. |
|
It was difficult to determine the duration of the staminate and pistillate phases in L. spicata because of pollinator activity. |
|
In a hermaphroditic plant, flowers are first staminate, then pistillate, and the sexual stages do not overlap within the flower. |
|
Pistillate flowers are initiated on the lower portion of the inflorescence and staminate flowers are initiated on the distal portion. |
|
Bract length was measured from the base of the bract to the apex of the midrib for both pistillate and staminate plants. |
|
By contrast, staminate flowers may occur on one plant and pistillate flowers on another, as in willows, poplars, and mulberries, which are dioecious. |
|
Finally, there is the trimonoecious group, which has a mixture of staminate, pistillate, and hermaphroditic flowers all on the same plant. |
|
Aging flowers along the indeterminate racemes shift from being staminate to carpellate. |
|
Anatomy of staminate flower ontogeny of the pecan as determined by scanning electron microscopy. |
|
Flowers last about 4 days, with 2 days spent in a staminate phase, followed by 2 days in a pistilate phase. |
|
We found that fruit set occurs after removal of either the distal spadix or the staminate flowers but not after removal of both. |
|
Factors that influence the duration of the staminate and pistillate phases of Lobelia cardinalis flowers. |
|
The scales of the staminate aments when mature are broadly ovate, rounded, yellow or orange color below the middle, dark chestnut brown at apex. |
|
Begonia sabahensis and B. calcarea are closely allied species with orange and yellow flowers respectively, borne on separate umbellate staminate and unifloral carpellate inflorescences. |
|
Begonia piring has paired carpellate flowers with 5 tepals borne beneath a larger staminate inflorescence and hence is likely affiliated with Begonia sect. |
|
The females lay their eggs in holes pierced in staminate buds. |
|
In banana and coconut flowers of both sexes are found in the same inflorescence, the staminate flowers at the tip and the pistillate flowers at the base. |
|
The eggs hatch in about 8-12 days, and the tiny larvae soon spin silken hibernation shelters in old staminate flower cups, under bark scales or lichens, and in bark crevices. |
|
The staminate inflorescences are large, showy, loose, axillary, cymose panicles, while the pistillate ones are small, obscure, congested, axillary, spicate cymes. |
|
|
Staminate flowers taken from herbarium specimens showed structurally complete stamens releasing large numbers of pollen grains. |
|
Staminate catkins are 2-3 mm in diameter with tricolpate platanaceous pollen within elongate anthers. |
|
Staminate aments are pendulous, clustered or solitary in the axils of the last leaves of the branch of the year or near the ends of the short lateral branchlets of the year. |
