|
capitulescence |
|
architecture |
|
Mode or progressive pattern of bearing capitula (heads); most appropriately described using adjectival terms; esp. in Asteraceae (Compositae). |
|
pilose |
|
pubescence |
|
Bearing relatively sparse, soft, slender, more or less erect capillate trichomes. See also pilosulous. |
|
neck (floral tube) |
|
STRUCTURE |
|
The solid, usually constricted portion of a floral tube sometimes present between casing and collar when those are both present. |
|
cauline |
|
insertion |
|
Upon, arising from, or otherwise directly associated with the stem. |
|
lateral |
|
insertion |
|
To, toward, at, or upon a side, not apical or basal. |
|
planoconcave |
|
solid shape |
|
Relatively thin with opposite broad faces, one plane and one concave. |
|
extravaginal |
|
insertion |
|
Distal to or outside the leaf sheath. |
|
nutlet |
|
nominative |
fruit |
A small, relatively hard-coated mericarp; esp. in Lamiaceae (Labiatae), Verbenaceae. |
|
cylindric(al) |
|
solid shape |
|
Solid and transversely round with a more or less uniform diameter, the ends blunt. |
|
levering |
|
habit |
trichome |
Forming part of a pappus and reflexing at maturity, thus helping to loosen the individual fruit (cypsela) from the capitulum (head); in Asteraceae (Compositae). |
|
stamen |
|
STRUCTURE |
|
A seed-plant organ that produces and releases pollen; usually comprising a stalk (filament) that bears a locular structure (anther) containing sporogenous tissue; however, the filament may be lacking and the anther sessile, or the stamen may be undifferentiated, the whole then consisting of microsporangia embedded in or borne upon the surface of a more or less planate body of sterile tissue; one of the constituent organs of a bisexual or a staminate flower; may be distinct or else connate with one or more others and/or may be free or else adnate with one or more other floral structures. |
|
obvolute 1 |
|
arrangement |
cotyledons |
Having each cotyledon folded inward longitudinally, the two facing one another with their edges overlapping alternately (each enveloping one side or the other). |
|
basifixed |
|
fixation |
|
Attached at its base. |
|
truncate 2 |
|
base |
|
Having a generalized proximal boundary that is more or less straight or plane and approximately perpendicular to the central axis. |
|
dimidiate |
|
solid shape |
|
Halved, figuratively; bilaterally asymmetric, nearly or wholly lacking one side as implicitly compared with some corresponding bilaterally symmetric structure, real or imagined. |
|
flesh |
|
STRUCTURE |
|
Tissue that is fairly firm and dense, juicy or at least moist, and easily cut. |
|
location |
|
CHARACTER |
|
Position with respect to aspects of environmental context. |
|
adnate |
|
fusion |
dissimilar structure(s) |
Intimately fused with or to one or more other dissimilar structures, the connection(s) with strong histological continuity. See also connate. |
|
follicetum pl. folliceta |
|
STRUCTURE |
|
An aggregate of follicles produced from a single flower with multiple simple pistils. |
|
sub-basifixed |
|
fixation |
|
Attached just above its base. |
|
complete |
|
architecture |
flower |
Having all sets of basic floral structures (calyx and corolla, or else undifferentiated perianth; androecium; and gynoecium) present and functionally normal. |
|
inframedial |
|
insertion |
|
Slightly below the middle of the structure in point. |
|
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. |
