In some species of plants, the flowers are imperfect or unisexual: having only either male (stamen) or female (carpel) parts. If unisexual male and female flowers appear on the same plant, the species is called monoecious. [27] However, if an individual plant is either female or male, the species is called dioecious.
Close-up of a Schlumbergera flower, showing part of the gynoecium (specifically the stigma and part of the style) and the stamens that surround it. Plant reproductive morphology is the study of the physical form and structure (the morphology) of those parts of plants directly or indirectly concerned with sexual reproduction.
The species is monoecious and forms imperfect flowers. Both male and female flowers are found on the current year's growth. The male flowers are long-stalked catkins, developing at the shoot base. [6] The female flowers are in short spikes on peduncles at the end of the shoot. Flowering occurs from April to May, shortly after the leaves have ...
Flowers: Zantedeschia is monoecious, in which separate male (staminate) and female (pistillate) flowers ("imperfect" or "unisexual" flowers) are carried on the spadix. The flowers are small and non-blooming without a perianth.
The zygomorphic flowers of Impatiens are protandric (male becoming female with age). The calyx consists of five free sepals, of which one pair is often strongly reduced. The non-paired sepal forms a flower spur-producing nectar. In a group of species from Madagascar, the spur is completely lacking, but they still have three sepals. The crown ...
