Term	Definition
Flying buttress	Buttress of a tree trunk that is elevated above the ground. Compare with plank buttress and running buttress.
Fodder pollen	Pollen that does not germinate and serves as a pollinator reward. This has been demonstrated in Couroupita guianensis and Lecythis pisonis (Mori et al., 1980) and is hypothesized for other species that appear to have staminodes on the inside of a flat hood or in stamens on the ligular side of the staminal ring.

Foliaceous	Leaflike; often used to describe cotyledons.
Foliolate	With leaflets; e.g., 3-foliolate or trifoliolate is a leaf with three leaflets.
Follicle	A dry or somewhat fleshy or leathery, dehiscent fruit formed from a single carpel and opening along a ventral suture; e.g., the fruit of Apocynaceae subfamily Asclepiadoideae.
Forb	Any non-woody flowering plant that is not a grass, sedge, or rush
Forb	A herbaceous flowering plant that is not graminoid (grasses, sedges and rushes).
Formicarium (plural = formicaria)	An ant domatium which is usually a swollen chamber associated with the petioles (e.g., species of Hirtella and Tococoa) or a hollow stem (e.g., Tachigali and Cecropia).

French spikes (= griffes or grimpettes in French)	Two iron spikes in the form of a half circle with three spikes at the apex and three spikes opposite a small platform that the collector stands on. These spikes are made by Lacoste et fils (12 av. Pasteur, 24160 Excideuil, France) and can be purchased through their web site at www.lacoste-outillage.com.

Fruto sincárpico	Es un fruto compuesto que tiene los carpelos connados; procede de un gineceo sincárpico
Fugacious	Falling off early. Same as caducous.
Functionally indehiscent fruit	A circumscissile fruit that opens via an operculum (lid) but the seeds are trapped inside because the size of the opening is smaller than the size of the seeds.
Funicle	The cord that attaches the ovule and subsequently the seed to the fruit wall.
Funicle (funiculus)	The cord that attaches the ovule and subsequently the seed to the fruit wall.
Funículo	Es la estructura filamentosa que conecta al óvulo con el ovario y subsecuentemente a la semilla con la pared del fruto
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.
Gamete	A haploid (n) reproductive cell, two of which fuse to form a diploid (2n) zygote.
Gametophyte	The gamete-producing haploid phase (n) of a plant's life cycle.
Gamopétala	Igual a simpétala
Gamopetalous corolla	Having petals united for at least part of their length. Same as sympetalous; Opposite of polypetalous and choripetalous.

Glándula	Estructura secretoria, como un nectario floral o extrafloral. Un cuerpo glandular ya sea que secrete o no; por ejemplo, el corpúsculo que conecta los dos polinios de las Apocynaceae subfamilia Asclepiadoideae
Glandular trichome	Hairlike outgrowths of the epidermis with bulbous expansions at their apices that presumably secretes substance that maket difficult for insect predators to eat the plant.
Glandular trichomes	Hairlike outgrowths of the epidermis with bulbous expansions at their apices.
Globose	Referring to a spherical solid shape.
Glume	A bract at the base of a spikelet in the Poaceae.
Ground layer	A hypothetical stratum of tropical rain forests consisting of herbs and other small plants that grow close to the ground. Same as ground story.

Growth form	The life form of a plant; e.g., herb, tree, or shrub. Same as habit.
Guard cells	Two cells that flank each side of the stomatal opening. These cells control the input and output of carbon dioxide and oxygen and the output of water by opening and closing at different times of the day.
