Leaf shape
In botany, the following terms are used to describe the '''shape of plant leaf|leaves''':
- Acicular (''acicularis''): Slender and pointed, needle-like
- Acuminate (''acuminata''): Tapering to a long point
- Aristate (''aristata''): Ending in a stiff, bristle-like point
- Bipinnate (''bipinnata''): Each leaflet also pinnate
- Compound: The combination of one leaflet arrangement within an arrangement at a larger level; e.g.:"bipinnate, twice-pinnate: the leaflets are themselves pinnately-compound"
- (''cordata''): Heart-shaped, stem attaches to cleft
- Cuneate (''cuneata''): Triangular, stem attaches to point
- Deltoid (''deltoidea''): Triangular, stem attaches to side
- Digitate (''digitata''): Divided into finger-like lobes
- Elliptic (''elliptica''): Oval, with a short or no point
- Falcate (''falcata''): sickle-shaped
- Flabellate (''flabellata''): Semi-circular, or fan-like
- Hastate, spear-shaped (''hastata''): Pointed, with barbs, shaped like a spear point, with flaring pointed lobes at the base
- Lance-shaped, lanceolate (''lanceolata''): Long, wider in the middle
- Linear (''linearis''): Long and very narrow
- Lobed (''lobata''): With several points
- Obcordate (''obcordata''): Heart-shaped, stem attaches to tapering point
- Oblanceolate (''oblanceolata''): Top wider than bottom
- Oblong (''oblongus''): Having an elongated form with slightly parallel sides
- Obovate (''obovata''): Teardrop-shaped, stem attaches to tapering point
- Obtuse (''obtusus''): With a blunt tip
- Orbicular (''orbicularis''): Circular
- Ovate (''ovata''): Oval, egg-shaped, with a tapering point
- Palmate (''palmata''): consisting of leaflets
- Pedate (''pedata''): Palmate, with cleft lobes
- Peltate (''peltata''): Rounded, stem underneath
- (''perfoliata''): Stem through the leaves
- Pinnate (''pinnata''): Two rows of leaflets
- odd-pinnate, imparipinnate: pinnate with a terminal leaflet
- paripinnate, even-pinnate: pinnate lacking a terminal leaflet
- pinnatifid and pinnatipartite: leaves with pinnate lobes that are not discrete, remaining sufficiently connected to each other that they are not separate leaflets.
- bipinnate, twice-pinnate: the leaflets are themselves pinnately-compound
- tripinnate, thrice-pinnate: the leaflets are themselves bipinnate
- tetrapinnate: the leaflets are themselves tripinnate.
- Pinnatisect (''pinnatifida''): Cut, but not to the midrib (it would be pinnate then)
- Reniform (''reniformis''): Kidney-shaped
- Rhomboid (''rhomboidalis''): Diamond-shaped
- Round (''rotundifolia''): Circular
- Sagittate (''sagittata''): Arrowhead-shaped
- Spear-shaped: see Hastate.
- Spatulate, spathulate (''spathulata''): Spoon-shaped
- Subulate (''subulata''): Awl-shaped with a tapering point
- Sword-shaped (''ensiformis''): Long, thin, pointed
- Trifoliate, ternate (''trifoliata''): Divided into three leaflets
- Tripinnate (''tripinnata''): Pinnately compound in which each leaflet is itself bipinnate
- Truncate (''truncata''): With a squared off end
- Unifoliate (''unifoliata''): with a single leaf
