Ovules bent over through 180 degrees to lie alongside its stalk (funicle).
Androecium: All the male reproductive organs of a flower, the stamens.
Gynoecium: All the female reproductive organs of a flower, comprising one or more free or fused carpels.
A column on which stamens and carpels are borne.
A plant producing seeds enclosed in an ovary. A flowering plant.
A plant that completes its life cycle from germination to death within one year.
The terminal part of the male organs (stamen), usually borne on a stalk (filament) and developing to contain pollen.
(singular antheridium). The male reproductive structure in moss and fern gametophytes
The period of flowering; from the opening of the flower bud to the setting of the seed.
The pigment usually responsible for pink, red, purple, violet and blue colors in flowering plants.
Occuring opposite the petals, on the same radius, as distinct from alternating with the petals.
Having one or more apertures.
Apex: The tip of an organ; the growing point.
Apical: Pertaining to the apex.
Mucronate: Tipped with a short, sharp, abrupt point (mucro).
Apiculate: Ending abruptly in a small, slender point
Acuminate: Narrowing gradually to a point.
With carpels free from each other.
Reproduction by seed formed without sexual fusion. (adj. Apomictic).
Living in water.
(singular archegonium). The female reproductive structure in moss and fern gametophytes.
A small, well-defined area on a surface, as the area between the veinlets of a leaf or the region of a cactus bearing the flowers and/or spines.
A fleshy or sometimes hairy outgrowth from the hilum or funicle of a seed.
Auricle: Small ear-like projections at the base of a leaf or leaf blade or bract.
Auriculate: Which has auricles.
A stiff, bristle-like extension to an organ, usually at the tip.
Axil: The upper angle formed by the union of a leaf with the stem.
Axillary: A bud, a flower or an inflorescence that originates where the leaf attaches to the axis.
A type of placentation in which the ovules are borne on placentas on the central axis of an ovary that has two or more locules.
A stem of lignous plant or the main or central stem of a herbaceous plant or of an inflorescence.
In mangrove forests, we can recognize three zones : the mangrove proper, the back mangroves and the slightly or not saline soils. The back-mangrove is a bushy, discontinuous vegetation type with Avicennia here and there and few other halophytes species.
Borne at or near the base.
Having the placement at the base of the ovary.
