|
Relatively thin with opposite, round, broad faces, one convex and one concave (as viewed externally), the circumferential edge angular or rounded; like a meniscus. See also discoid (disciform), lenticular (biconvex, lens-shaped), patelliform (kneecap-shaped). |
|
involucre 1 |

One or more closely proximate whorls, or a compact spiral, of bracts immediately subtending an inflorescence, the bracts sometimes leaf-like, sometimes petaloid. |
|
pericarp |
|
STRUCTURE |
|
The portion of a fruit wall that is derived from the ovary wall; consisting of three more or less distinct tissue layers (exocarp or epicarp, mesocarp, and endocarp) that may or may not differ greatly in structure and/or function; the wall of a fruit, excluding any tissues of extra-ovarian (accessory) origin. |

|
architecture |
flower, androecium |
Having stamens unequal in size and/or shape. |
|
monolete |
|
architecture |
spore |
Having a single linear tetrad scar (surficial ridge or angle resulting from ontogenetic coherence with others produced from the same spore mother cell). |
|
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. |
|
thallus 2 pl. thalli |
|
STRUCTURE |
|
The main body of a gametophyte, bearing rhizoids, gametangia (antheridia and/or archegonia), and/or gemmae cups; usually thin and more or less planate, inconspicuous, and growing appressed to or beneath the substrate surface; in Psilotophyta, Lycopodiophyta, Equisetophyta, Polypodiophyta. See also prothallus. |
|
arrangement |
|
CHARACTER |
|
Disposition of equivalent structures with respect to one another (positions/insertions and/or orientations, regarded collectively) within some explicit or implicit standard context. Overlaps conceptually with habit, insertion, orientation, position, and shape. |
|
haplomorphic |
|
architecture |
flower |
Having the members of each set of basic floral structures numerous and spirally arranged, the flower hemispheric to conoidal overall. |
|
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. |
|
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. |
|
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). |
|
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). |
