Androphore
|
A stalk elevated above the point of perianth attachment and supporting the stamens; e.g., the united filaments of species of Menispermaceae and Myristicaceae. |

Androphore
|
A stalk elevated above the point of perianth attachment which supports the stamens. |
|
|
Anemophily (anemophilous)
|
Pollination by the wind, i.e., the movement of pollen by the from the stamens of a flower to the stigma of another flower. This includes movement for the anther to the stigma of the same flower, from the anther to the stigma of another flower on the same plant, or from the anther of a flower on one plant to the stigma of a flower on another plant. Same as wind pollination. |
|
|
Aneomochory (nemochorous)
|
Referring to a fruit or seed adapted for dispersal by wind. |
|
|
Angiosperm
|
A flowering plant whose seeds are borne within a fruit derived from a carpel or carpels. |
|
|
Anisocytic stomata
|
Referring to a stomatal type in which one of the subsidiary cells surrounding a stomate is smaller than the other epidermal cells. |
|
|
Anisocytic stomata
|
Referring to a stomatal type in which one of the subsidiary cells surrounding a stomate is smaller than the other epidermal cells. |
|
|
Anisophylly (anisophyllous)
|
With two leaves of a pair differing in shape and/ or size; this is relatively common in species of Melastomataceae.. |
|
|
Annual
|
Plant with a life cycle of one year or less from seed to maturity and death. Compare with biennial and perennial. |
|
|
Anomocytic stomata
|
Referring to a stomatal type in which the subsidiary cells surrounding a stomate are not differentiated from the other epidermal cells. |

Anomocytic stomata
|
Referring to a stomatal type in which the subsidiary cells surrounding a stomate are not differentiated from the other epidermal cells. |
|
|
Ant dispersal
|
Referring to the process in which ants carry away diaspores from parent plants thereby effecting dispersal of those plants. The ants are usually attracted to fleshy structures associated with seeds such as elaiosomes. |
|
|
Antepetalous
|
Referring to structures, usually stamens, inserted opposite or facing the petals. |
|
|
Anterior end of flower
|
The most distal end of the flower but not including inner coils, i.e., the end of a zygomorphic-flowered Lecythidaceae into which a pollinator enters to reap a pollinator reward. |
|
|
Anterior hood extension
|
An extension of the ligule beyond the point where the androecial hood splits into two extensions, this extension is the uppermost division of the androecial hood split and extends forward from the split. |
|
|
Antesepalous
|
Referring to structures, usually stamens, inserted opposite or facing the sepals. |
|
|
Anther
|
The pollen-bearing part of the stamen. |
|
|
Anther
|
The pollen-bearing part of the stamen. |
|
|
Anther connective
|
The tissue that connects the thecae on one side of an anther to the thecae on the other side. |
|
|
Anther dehiscence lateral
|
Referring to the anthers of many flowering plants that open along the side. |
|
|
Anther dehiscence lateral
|
Anthers that dehisce by lateral slits. |
|
|
Anther dehiscence poricidal
|
Anthers that open (dehisce) and release pollen via a terminal pore. |
|
|
Anther theca (pl. = thecae)
|
The chambers of an anther in which the pollen is produced. Same as pollen sac. |
|
|
Anther versatile
|
A stamen in which the filament is attached to the anther above the base of the anther. |
|
|
Antheridium (plural = antheridia)
|
Referring to a multicellular haploid structure in which sperm is produced in mosses, hepatics, ferns, and relatively few vascular plants. |
