carpellate การใช้

• The carpellate flowers have been interpreted differently.
• It is dioecious, i . e . with staminate and carpellate flowers on separate plants.
• Carpellate flowers are roughly 3 to 4 mm in diameter, with 7 or 8 tepals.
• Ovary 4 or 5 (-8 or more ) carpellate; styles free or rarely connate at base.
• The flower has a syncarpous gynoecium ( fused-carpellate ovary ) with 5 carpels and has parietal placentation.
• Plants have either bisexual flowers or both staminate ( " male " ) and carpellate ( " female " ) flowers.
• Flowers may appear in early March to late May in rotund-ovate, three carpellate subsessile fruits 5 to 8 mm long.
• On either side of the solitary carpellate flower there are two branches each with five or six staminate ( " male " ) flowers arranged at 1 3 mm intervals.
• They have separate " male " ( staminate ) and " female " ( carpellate ) flowers, mostly on the same plant ( i . e . they are mostly monoecious ).
• Structurally, the flowers may be bisexual, consisting of two stamens and an ovary, or may be male ( staminate ), lacking a functional ovary, or female ( carpellate ), lacking functional stamens.
• Heads may have florets of one sexual morphology  all bisexual, all carpellate or all staminate ( when they are called homogamous ), or may have mixtures of two or more sexual forms ( heterogamous ).
