Type of inflorescence in which all pedicles (floral stalks) eradiate from a common point. E.g., geranium, gardenia. One can also say the umbel is a raceme whose axis did not elongate: the younger flowers are in the center and the older gradually distal. (Also see Raceme, Inflorescence).
Undulated
Leaf or petal with wavy margin. The term is not applied to serrated or toothed margins.
Unisexual
Monoecious or Dioecious plants in which the flower are male or female; flower that is not hermaphroditic, but is either male or female. (compare with Hermaphrodite).
Fruit: Any adult ovary containing mature seeds. The outer cover can be smooth and fleshy, like berries; or dry, like the Streptocarpus; organ resulting from the development of a flower’s ovary, generally following fertilization, although in some cases the fruit can result from the development of the ovary determined by a different stimulus than fertilization.
