Facing away from the stem of a plant (especially denoting the lower surface of a leaf).
Narrow with a sharp stiff point.
A simple, dry, one–seeded (one–celled) fruit
Having a low pH, opposite of basic or alkaline.
Pointing towards, or on the side of, the apex
Gradually tapered to a point. Sharply pointed.
Pointed or sharp, tapering to a point with straight sides.
Fusion of unlike parts, e.g. stamens fused to petals.
A plant that grows in the wild in New Zealand but which was introduced to the country by humans.
An organism that releases compounds that are toxic to other species.
The release by an organism of compounds that are toxic to other species.
Attached singly at each node but changing from one side of a stem to the other.
Honeycombed with ridged partitions.
clasping or surrounding the stem
Asexual fruiting stage, usually of an ascomycete fungus.
Rejoining after branching, as in some leaf veins.
A plant that completes its complete life cycle within the space of a year
Plants that lose their over-wintering leaves rapidly in the first half of the growing season. Annual evergreens never present a leafless appearance, but are closer in a functional sense to a deciduous plant than they are to multi-annual evergreens.
Line of thickened cells that governs the release of spores from a sporangium

When the flower is fully developed and functioning. The time of pollination or bloom.

Plural of apex. Tip, the point furthest from the point of attachment
Bearing a short slender and flexible point.
A form of reproduction whereby seed is formed without the usual mode of sexual fusion

Growing, or living in, or frequenting water. Applied to plants and animals and their habitats. Opposite of terrestrial (land living).
Female reproductive organ of a fern formed on the prothallus
Curved into an arch.
An often fleshy appendage on the outside of a seed.

Growing obliquely upward.
Vegetative reproduction, lacking sexual involvement by sperm or egg cells

Bearing a small, ear-shaped appendage.
Of or relating to organisms (as green plants) that can make complex organic nutritive compounds from simple inorganic sources by photosynthesis
A stiff or bristle like projection often from the tip or back of an organ
The upper angle between the leaf and the stem.
The longitudinal supporting structure around which organs are borne, e.g., a stem bearing leaves.
