Perfect: (of flowers) see bisexual. [6] Polygamodioecious: mostly dioecious, but with either a few flowers of the opposite sex or a few bisexual flowers on the same plant. [2] Polygamomonoecious: see polygamous. [6] Or, mostly monoecious, but also partly polygamous. [2] Polygamous: having male, female, and bisexual flowers on the same plant. [6]
A single plant can bear both male and female flowers, from mid-spring to mid-summer. Some plants may produce bisexual flowers as well, thus totaling three types of flower on a single plant. The flowers are white to cream in color and range from 10 millimeters (0.4 inch) to 30 millimeters (1.2 inches) in length. [7]
Flowers are often short-lived, lasting for a day or less. The flowers of Commelinaceae are ephemeral, lack nectar , and offer only pollen as a reward to their pollinators. Most species are hermaphroditic , meaning each flower contains male and female organs, or andromonoecious, meaning that both bisexual and male flowers occur on the same plant.
Floral sexuality is related to the presence or absence of the reproductive whorls: androecium and gynoecium. Flowers that have both whorls (i.e., will produce both male and female gametes) are said to be perfect, bisexual, monoclinous or, more frequently, hermaphrodites, as is the case with potato flowers (Solanum tuberosum, Solanaceae
The flower is bisexual, it contains 5 stamens, the pistil is fused of five carpels, and the ovary is inferior. A floral formula is a notation for representing the structure of particular types of flowers .
The flowers would have tended to grow in a spiral pattern, to be bisexual (in plants, this means both male and female parts on the same flower), and to be dominated by the ovary (female part). As flowers grew more advanced, some variations developed parts fused together, with a much more specific number and design, and with either specific ...
The flowers are bisexual and are arranged in cymes in leaf axils or on the ends of branchlets. The four sepals are fused, at least at the base, forming a cup-shaped calyx. The four petals are usually fused for most of their length to form a tubular corolla and the eight stamens are free from each other.
The lower, or proximal, cincinnus bears 1 to 4 bisexual flowers and is nearly included in the spathe, while the upper cincinnus has 1 to 2 male flowers and is about 8 mm (0.31 in) long. [2] [4] The individual flowers are subtended by bracteoles that fall off early in development.
