STRUCTURE |
|
A portion of a lamina that is prolonged and adherent to the supporting axis beneath the point of vascular insertion. |
pseudoterminal |

|
Only apparently terminal; originally subapical but displaced toward the apex by differential growth during development. |
ceraceous 2 |
cereous, waxen, waxy |
texture |
|
Having the consistency of wax. |
lentiginose |
= dusty, lentiginous |
coating |
|
Covered with a more or less even deposit of minute, dry, macroscopically indistinguishable particles. See also pulverulent (granuliferous, powdery), which is not clearly distinct in its application. |
transverse 2 |
|
orientation |
|
Perpendicular to the long axis of the context of reference. |
maturation |
|
CHARACTER |
|
Timing of the attainment of functional maturity, sometimes relative to other structures, sometimes as to constituent structures relative to each other. |
flabellate |
= fan-shaped, flabelliform |
solid shape |

Strongly compressed, broadest near the apex and attenuate to a narrow base, plaited longitudinally, the alternating folds radiating from the base, the whole basically triangular in broad aspect; like a partially expanded folding fan. |
scutellate |
= platter-shaped, scutelliform |
solid shape |
|
Relatively thin with opposite broad oval faces, shallowly concave-convex; like a serving platter. See also scutate (buckler-shaped, scutiform), which is not clearly distinct in its application. |
basal |
< proximal |
position |
|
At or very near the developmental origin (base) of a structure. |
bracteate |
= bracted |
architecture |
|
Bearing or subtended by one or more bracts. |
inframedial |
|
insertion |
|
Slightly below the middle of the structure in point. |
superaxillary |
|
position |
|
Internodal but close to and directly above the axil(s). |
endosperm |
= albumen |
STRUCTURE / SUBSTANCE |
|
A genetically triploid (3n chromosomes) nutritive tissue in a seed; containing stored carbohydrate and/or oil utilized by the embryo prior to and especially upon germination; derived from fusion of the two polar nuclei (n + n chromosomes) of the embryo sac with a sperm nucleus from the pollen tube (n chromosomes). See also perisperm. |
resin |
|
SUBSTANCE |
|
A substance of high molecular weight consisting of organic acids, esters, and/or terpenes, produced within plant tissue and exuded from wounds as a liquid that hardens to an amorphous glassy state upon exposure. |
composite |
= compound |
architecture |
|
Unitary as a whole but comprising two or more equivalent substructural entities, these topologically distinct (e.g., leaflets in a compound leaf) or not (e.g., carpels in a compound pistil). |
crista pl. cristae |
= crest |
STRUCTURE |
|
A laterally elongate, relatively thin, irregular or notched, apical protrusion. |
six-… |
= hexa… |
prefix |
|
Indicating presence of or constitution by six entities of the type denoted by the term's stem; as in six-angled, six-sepaled, six-styled. |
hastula pl. hastulae, hastulas |
= ligule misapplied |
STRUCTURE |
|
An outgrowth or enation from the petiole apex at its junction with the adaxial surface of a palmate leaf blade; often woody in texture; variously shaped, its adaxial outline usually resembling an inverted V or U, or a semicircle with the opening proximal; esp. in Arecaceae (Palmae). |
phyllopodium pl. phyllopodia |
|
STRUCTURE |
|
A stem-like axis composed of fused leaf bases; esp. in Arecaceae (Palmae), Musaceae. |
lanciform |
= lancehead-shaped, lanceoloid |
solid shape |
|
Considerably longer than broad, compressed or not, broadest near the base and somewhat concavely attenuate to the apex, the attenuation in all median longitudinal planes or else largely confined to one, depending upon the extent of compression, if any. See also oblanciform (oblanceoloid). |
thrice-… |
= tri…, triple-… |
prefix |
|
Indicating presence of three hierarchical orders of the type of entity or pattern denoted by the term's stem; as in thrice-pinnate. See also three-… (tri…). |
female |
= feminine |
reproduction |
|
Of the sex that produces megaspores and ova. |
scabrid |
= rough, scabrate, scabridous, scabrous |
relief |
|
Having small, stout, stiff, more or less acute protrusions. |
ostiole |
|
STRUCTURE |
|
The distal aperture of a syconium (fig); in Ficus (Moraceae). |
