The following definitions are taken from Guide to the Vascular Plants of Florida (1st ed., 1998) by Richard P. Wunderlin.

  • apex – The tip.
  • alternate – Situated one at each node.
  • bipinnate – Compound leaves divided into segments (pinnae) with each segment again divided into segments.
  • blade – The expanded part of a leaf or petal.
  • crenate – Toothed with shallow, rounded teeth; scalloped.
  • crown – Mass of foliage and branches growing upward from the trunk of the tree.
  • drupe – A fleshy fruit in which the seed is surrounded by a hard covering; usually one-seeded.
  • entire – A margin without teeth, lobes, or divisions.
  • frond – Leaf of a fern or palm.
  • glabrous – Without hairs.
  • herbaceous – Lacking persistent woody parts.
  • inflorescence – A cluster of flowers arranged on an axis.
  • lacerate – Torn, or with an irregularly jagged margin.
  • lanceolate – Lance-shaped; broadest near the base, gradually tapering to an apex.
  • leaflet – A unit of a compound leaf; secondary leaf.
  • midrib – The main vein of a leaf or leaflet.
  • node – The place on the stem where a leaf or branch is attached.
  • opposite – Situated directly across from each other at the same node or level.
  • odd-pinnate – A pinnately compound leaf terminating with a single leaflet. 
  • ovate – Egg-shaped in outline; broader below the middle and rounded at both ends.
  • palmate – Lobed, divided, or veined in a radiate or digitate manner.
  • panicle – A branching, racemose inflorescence.
  • pedicel – Stalk of one flower in an inflorescence.
  • peltate – Attached to the stalk away from the margin toward the center.
  • petaloid – Petal-like in texture and color.
  • pinna (pl. pinnae) – The primary divisions or leaflets of a pinnately compound leaf.
  • pinnate – A compound leaf divided once, with the leaflets arranged on both sides of the axis.
  • rachis – The primary axis of an inflorescence or a pinnately compound leaf.  
  • rhizome – A horizontal stem, often underground.
  • rosette – A cluster of leaves arranged in a circle at the base of a plant.
  • serrate Toothed along the margin with sharp, forward-pointing teeth.
  • sessile – Without a stalk.
  • sheath – Any long, tubular organ surrounding another organ.
  • smooth – A surface not rough to the touch.
  • spike – An unbranched, elongate, indeterminate inflorescence with sessile flowers.
  • spikelet – A secondary spike; the floral unit of the Poaceae (Grass family), consisting of the rachilla , glumes, and one or more florets.
  • sporangium (pl. sporangia) – A spore case.
  • spore – The one-celled reproductive structure of the sporophyte generation.
  • terminal – At the tip.
  • trichome – A hair.
  • truncate – With the base or apex nearly straight across.
  • tuber – A short, congested, storage organ, usually an underground part of the root or rhizome, more rarely an aerial structure, used for reproduction.
  • umbel – An inflorescence in which the pedicels arise from a common point.
  • undulate – With wavy margin or surface.
  • whorled – Arranged with three or more leaves at a node or another common point.
