Funicle (funiculus)
|
The cord that attaches the ovule and subsequently the seed to the fruit wall. |
|
|
Funneliform
|
Usually referring to a corolla in the shape of a funnel but can also be applied to other structures with a similar shape. |
|
|
Fused (fusion)
|
Referring to similar structures fused to each other, such as the petals of a sympetalous corolla. Same as connate. Compare with adnate and connivent. |
|
|
Gamopetalous corolla
|
Having petals united for at least part of their length. Same as sympetalous; Opposite of polypetalous and choripetalous. |
|
|
Gamosepalous calyx
|
Having sepals united for at least part of their length. Same as synsepalous calyx. |
|
|
Globally symmetrical pollen
|
In the Malpighiaceae, pollen with the pores not all in the same plane and the ectoapertures, if present, variously oriented. |
|
|
Glume
|
A bract at the base of a spikelet in the Poaceae. |
|
|
Gynobasic style
|
Referring to a style arising from the base of the ovary. Gynobasic styles are of two types: 1) the style is inserted laterally at the base of a syncarpous ovary as in Chrysobalanaceae and Rhabdodendraceae 2) the style arises from the center of an apocarpous ovary as in many species of Lamiaceae. |
|
|
Gynoecium (plural = gynoecia)
|
The collective term for the pistillate structure (the pistils) of the flower. Compare with androecium. |
|
|
Gynoecium apocarpous
|
Referring to a gynoecium of distinct carpels; e.g., many species of Annonaceae, Crassulaceae, Menispermaceae, Ranunculaceae, Rosaceae, etc. Compare with syncarpous. |
|
|
Gynoecium syncarpous
|
A gynoecium composed of fused carpels. |
|
|
Gynophore
|
Stalk of the ovary; e.g., in Capparaceae and Simaroubaceae. Same as stipe. |
|
|
Gynostegial corona
|
A corona derived from the gynostegium. |
|
|
Gynostegium
|
The structure formed by the fusion of the stamens and the stigmatic region of the gynoecium in the Apocynaceae subfamily Asclepiadoideae. Compare with column in the Orchidaceae. |
|
|
Gynostemium
|
In the Aristolochiaceae, a structure formed by the fusion of the stamens to the style and stigma. |
|
|
Haplostemonous
|
Referring to an androecium with a single series of stamens in one whorl. |
|
|
Heteranthery (adj. = heterantherous)
|
A flower that contains two types of pollen, one that germinates and is found in anthers and another that does not germinate and is found antherodes; the latter serves as a pollinator reward. |
|
|
Heteranthery (heterantherous)
|
Heteromorphic stamens of a species of Swartzia from an unvouchered plant from Amazonas, Brazil. This is also called heteranthery and when there are only two variations in the morphology of a structure it can also be referred to as dimorphic. This species is apocarpic as evidenced by the separate styles, a rare occurence in legumes which in general have species with a single pistil. Same as differentiated anthers. |
|
|
Heterochlamydeous
|
Referring to a flower with differentiated calyx and corolla; same as biseriate perianth. Compare with monochlamydeous. |
|
|
Heterogamous
|
Having flowers of two or more different types; e.g., the heads of certain Asteraceae with both ligulate and disk flowers. |
|
|
Heteromorphic stamens
|
Stamens of two distinct types; one type usually bears fertile pollen and the other type bears sterile or fodder pollen; e.g., Lecythis zabucajo (Lecythidaceae) and species of Senna (Fabaceae). |
|
|
Homogamous
|
Possessing flowers of one kind; e.g., the heads of certain Asteraceae with only disk flowers; referring to flowers in which the anthers release pollen at the same time as the stigma(s) is (are) receptive. |
|
|
Homostyly
|
A condition in which the style and stamen lengths are more or less the same in all individuals of a species. Opposite of heterostyly. |
|
|
Honey guide
|
Same as nectar guide. |
|
|
Hood
|
One of five hollow chambers of the corona of some species of Apocynaceae subfamily Asclepiadoideae; see androecial hood. |
