thrice-… |

STRUCTURE |
|
A laterally elongate, relatively thin, irregular or notched, apical protrusion. |
carpophore 3 |
= columella; < stalk |
STRUCTURE |
|
The stalk supporting a mericarp after dehiscence of a schizocarpic fruit, the central axis of the fruit having split longitudinally to yield two or four such stalks; composed of receptacular and (primarily) gynoecial tissues; esp. in Apiaceae (Umbelliferae). |
basifixed |

ostiole |
|
STRUCTURE |
|
The distal aperture of a syconium (fig); in Ficus (Moraceae). |
epidermal cell |
|
STRUCTURE |
|
Any of the unspecialized cells of an epidermis; i.e., any other than stomatal guard cells or cells directly associated with trichomes. While the latter specialized cells are also properly epidermal cells, they are treated separately for descriptive purposes and, for the sake of convenience, use of the general term is restricted to the unspecialized cells that constitute the bulk of an epidermis. |
prolate |
|
plane shape |
|
Symmetrically elongate parallel to the developmental or polar axis. |
prolate |
|
solid shape |
|
Symmetrically elongate parallel to the developmental or polar axis. |
fringe |
= fimbria |
STRUCTURE |
|
A marginal series or cycle of regular, slender, closely adjacent, more or less flexible segments or protrusions, when treated as an aggregate structure. |
sheath (leaf) |
|
STRUCTURE |
|
The lower (basal or proximal), fundamentally laminar but strongly involute portion of one of the non-petiolate leaves characteristic of most monocotyledons (Liliidae); distinct from the leaf blade, which, when present, is borne distally upon it; analogous, though not necessarily homologous, with a petiole; usually more or less completely enclosing a portion of the stem above the node from which the leaf is borne. |
perianth tube |
|
STRUCTURE |
|
A relatively narrow, fully connate portion of a syntepalous (gamotepalous) perianth proximal to a broader portion (limb) that comprises the distinct or connate distal portions of the tepals. |
filamentous |
|
texture |
|
Composed of filiform (thread-like) strands with no intervening tissue. |
adaxial |
= ventral (not recommended) |
position |
|
On or pertaining to the side or portion of a lateral structure that faces (or would face) toward the bearing axis when (or if) the axis of the lateral structure is (or were) oriented in the same general direction as the bearing axis. |
knobby |
= knotty, nodose |
solid shape |
|
Having knob-shaped (gongylodate, gongyloid, knot-shaped, nodiform) protrusions. See also nodulose. |
tendril |
|
STRUCTURE |
|
A slender stem branch, modified leaf, or portion of a leaf that twines about a supporting structure. |
raphides sing. raphis |
|
STRUCTURE |
|
Needle-like crystals of calcium oxalate contained within the cells of some plants; esp. in Araceae. |
canalicular |
|
insertion |
|
Upon or otherwise directly associated with the channel of a petiole or petiolule. |
axehead-shaped |
= dolabrate |
solid shape |
|
Like an axe head oriented cutting edge downward. |
multi… |
= many-…, pluri…, poly… |
prefix |
|
Indicating presence of or constitution by a relatively large number of entities of the type denoted by the term's stem; as in multicarpellate, multicellular, multifacial, multiseriate. See also oligo… (few-…). |
wall (fruit, ovary, pollen, spore) |
|
STRUCTURE |
|
The exterior layer of tissue(s) enclosing anatomically distinct interior tissues and sometimes fluid and/or one or more cavities. |
spongy |
|
texture |
|
Soft, light, discontinuous but cohesive, and somewhat resilient. |
lineolate 2 |
|
relief |
|
Finely lineate, the depressions or protrusions short and often irregularly oriented. |
tuber |
|
STRUCTURE |
|
An enlarged, basically subterranean stem segment or thallus outgrowth containing a high proportion of storage tissue and functioning as a perennating and often vegetatively propagative structure. |
runner |
= stolon |
STRUCTURE |
|
A slender stem that grows horizontally upon or just beneath the ground surface, rooting at the nodes and giving rise to erect shoot segments at some nodes and/or at its apex. |
