Protogynous: (of dichogamous plants) having female parts of flowers developed before male parts, e.g. having flowers that function first as female and then change to male or producing pollen after the stigmas of the same plant are receptive. [6] Subandroecious: having mostly male flowers, with a few female or bisexual flowers. [24]
Diagram of flower parts. In botany, floral morphology is the study of the diversity of forms and structures presented by the flower, which, by definition, is a branch of limited growth that bears the modified leaves responsible for reproduction and protection of the gametes, called floral pieces.
The column, or technically the gynostemium, is a reproductive structure that can be found in several plant families: Aristolochiaceae, Orchidaceae, and Stylidiaceae. It is derived from the fusion of both male and female parts ( stamens and pistil ) into a single organ. [ 1 ]
Autoicous – produces male and female sex organs on the same plant but on separate inflorescences. Bract – leaf is present below the flower. Cladautoicous – male and female inflorescences are on separate branches of the same plant. Dioicous – having two forms of gametophyte, one form bearing antheridia and one form bearing archegonia.
Lower part of spathe cut open – showing in succession (from below) female flowers, male flowers, and sterile flowers forming a ring of hairs borne on the spadix, 4. Spike of fruits Many small rodents appear to find the spadix particularly attractive; finding examples of the plant with much of the spadix eaten away is common.
Male flower. Antennaria plantaginifolia is dioecious, meaning that the male and female flowers are borne on separate plants. It often forms colonies, sometimes consisting entirely of male or female plants. It does so in part through vegetative reproduction. Stolons emerging from the basal rosette take root and develop into new plants.
Boophone disticha is a bulbous tropical and subtropical flowering plant, endemic to Africa.Commonly called the century plant [4] or tumbleweed, [3] Boophone disticha was first collected in 1781 from South Africa by Swedish botanist Carl Peter Thunberg and described by Carl Linnaeus as Amaryllis disticha. [2]
Rhexia mariana is a perennial plant. [10] Each flower is perfect, containing both male and female parts. [10] Bees are the main pollinators, their buzzing is what triggers the plant to eject pollen. [10] The roots of this plant often grow laterally. [7]
