Flora
|
A book in which all of the species of a given group of plants for a given geographic area are described and illustrated to some extent. In addition, dichotomous keys used for indentification are provided. |
|
|
Floral aromas
|
Aromas emitted by plants to attract pollinators. These aromas can be extracted from plants by enclosing the flowers in bags or glass globes and then pumping the air from around the flowers through a tube with adsorbents. The samples are passed though a Gas Chromatograph and the chemical composition of the aromas of different flowers are identified by comparing the samples with a database of known compounds (Knudsen & Mori, 1996). There is a correlation between different floral aromas and the pollinators that visit the flowers. |
|
|
Floral cavity
|
A minute cavity on the dorsal side of Wolfia and Wolfiella (Lemnaceae) in which flowers are produced; note that vegetative buds are not produced in this cavity. |
|
|
Floral tube
|
A tube formed by the fusion of sepals, petals, or both, or as an outgrowth of the hypanthium. Nectar often accumulates within the floral tube. |
|
|
Floret
|
In the Poaceae, the term includes the lemma and palea as well as the enclosed flower; sometimes used to refer to the flowers of Asteraceae. |
|
|
Flower bisexual
|
A flower with a functional androecium (the male part of the flower and all parts derived from it) and a functional gynoecium (the female part of the flower). |
|
|
Flower oxidizes bluish-green
|
When the flower is bruised, the color at the point of the bruise turns bluish-green. |
|
|
Flowering associated with leaf flush
|
A phenological strategy in which a tree drops its leaves, flowers when the canopy is leafless or partially leafless, and flushes new leaves after flowering or flowers at about the same time that new leaves are flushed; i.e., there is some association between flowering and leaf fall and flush. |
|
|
Flowering not associated with leaf flush
|
A phenological strategy in which there is no apparent relationship between leaf drop, leaf flush, and flowering. |
|
|
Flowering plant
|
A plant whose seeds are borne within a fruit derived from a carpel or carpels. |
|
|
Flowering plant life cycle
|
Referring to the alternation of generations between the gameophyte (haploid) and sporophyte (diploid) stages of a floweirng plant. The most conspicuous stage of the life cycle is the sporophyte generation whereas the gametophyte generation is small and inconspicuous. Flowering plants are heterosporous because they have two different kinds of spores, the pollen grain and the embryo sac which contains a egg. |
|
|
Fluted
|
Same as sulcate. |
|
|
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. |
