bristle 1 |
= arista, awn, seta |
STRUCTURE |
|
A slender, more or less straight and stiff, fine-pointed, terminal or subterminal appendage or prolongation, sometimes a continuation of the bearing structure's central primary vein, as on a glume, lemma, or palea in Poaceae (Gramineae). |
|
nucellus pl. nucelli |
|
STRUCTURE |
|
The distinct, genetically diploid tissue layer immediately surrounding the embryo sac of an ovule; often considered equivalent to a megasporangium wall. |
|
partial |
|
extent |
|
Not reaching fully from the ovary wall or pericarp to the center of the ovary or fruit and/or from the apex to the base of its interior, thus not completely separating adjacent locules, which are recognized and delimited by extrapolating from the incomplete septal boundary(ies), the ovary or fruit nonetheless effectively unilocular. |
|
corticate |
= hard-coated |
texture |
|
Having a hard exterior layer and a distinct, softer interior. |
|
reclinate |
|
vernation |
|
Each with its blade oriented downward and parallel to the proximal portion of its distally recurved petiole. |
|
epirhizal |
|
insertion |
|
Upon or arising from the roots. |
|
scarious |
|
texture |
|
Very thin, dry, and not green. |
|
hair-like |
= capillary, capillate |
solid shape |
|
Finely filiform; resembling a hair. |
|
strict |
|
course |
|
Lacking any curve or bend. |
|
indusium pl. indusia |
|
STRUCTURE |
|
A protective membrane that is an outgrowth from the epidermis and covers a sorus during its maturation; in Polypodiophyta. |
|
tessellate 1 |
= checkered |
coloration |
|
Having a pattern of more or less regularly disposed square zones of contrasting hues and/or intensities. |
|
unguis pl. ungues |
= claw |
STRUCTURE |
|
The abruptly much narrower proximal portion, when present, of a laminar structure, esp. a petal; of variable shape itself, but usually attenuate toward the base. |
|
lemma pl. lemmata, lemmas |
|
STRUCTURE |
|
The proximal bract of the (usually) two that immediately subtend the flower in a grass (Poaceae) floret; the other is the palea. |
|
…lobed |
? …cleft, …fid, …lobate, …parted, …partite, …segmented |
plane shape |
|
Having the number of lobes indicated by the prefix; as in five-lobed. |
|
bladder |
= ampulla |
STRUCTURE |
|
A small, membranous, hollow, flask-shaped, insectivorous structure borne on a submerged leaf; esp. in Lentibulariaceae. |
|
near-bald |
= glabrate |
pubescence |
|
Nearly glabrous, with only a very sparse covering of trichomes. |
|
cauline |
|
insertion |
|
Upon, arising from, or otherwise directly associated with the stem. |
|
palmatifid |
|
plane shape |
|
Palmately lobate; having three or more lobes whose longitudinal axes radiate from a common point. |
