stigmatic |
|
habit |
trichome |
Borne on the surface of the stigma and serving to hold pollen deposited there, variously shaped, often glandular, sometimes contractile. |
microsporocarp |
|
STRUCTURE |
|
A sporocarp that bears only microsporangia. |
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. |
cylindric(al) |
|
solid shape |
|
Solid and transversely round with a more or less uniform diameter, the ends blunt. |
digamous |
|
reproduction |
inflorescence |
Bearing flowers of two differing sexual constitutions; esp. in Asteraceae (Compositae). |
mucronate |
|
apex |
|
Terminating abruptly in a short, hard point that is a continuation of vascular tissue. See also apiculate, mucronulate. |
sympodial |
|
architecture |
axes |
Branching laterally, each axis of each apparent order of branches comprising a series of laterally derived segments each of which functioned in turn as the distal leader, the apical meristem of each segment dominant until supplanted by that of the next. See also monopodial. |
obvolute 2 |
|
vernation |
|
Conduplicate with the lateral edges of each leaf alternately overlapping those of the oppositely oriented, distally next adjacent one. |
superposed 2 |
|
insertion |
buds |
Axillary in pairs, one member of each pair directly above the other. |
obdeltate |
|
plane shape |
|
Approximately equilaterally triangular, broadest distally, and regularly attenuate to an angular base; inversely deltate; equilaterally cuneate. |
throat 1 |
|
STRUCTURE |
|
The far distal portion of a perianth, calyx, or corolla tube, or of a leaf sheath, surrounding the orifice of the tube or sheath, sometimes constricted relative to the diameter of the main body of the tube or sheath; except in disc florets of Asteraceae (Compositae). |
eusporangiate |
|
reproduction |
|
Having relatively large sporangia each of which develops from a group of initial cells that, by periclinal divisions, give rise to an outer layer of primary cells and an inner layer of sporogenous cells; in Psilotophyta, Lycopodiophyta, Equisetophyta, and some Polypodiophyta. |
divaricate |
|
arrangement |
|
Strongly divergent. |
petiolar |
|
insertion |
|
Upon or otherwise directly associated with the petioles. |
terminal |
|
insertion |
|
Apical and with the same developmental axis as the whole, of which it is the distalmost portion or appendage. |
epigynous |
|
insertion |
perianth, calyx, corolla, androecium |
Having its proximal portion adnate to the full length of the gynoecium, the free portion thus arising from the apex of the gynoecium. See also hypogynous, perigynous. |
petiolar |
|
position |
|
Upon or otherwise directly associated with the petioles. |
ostiole |
|
STRUCTURE |
|
The distal aperture of a syconium (fig); in Ficus (Moraceae). |
tubercle |
|
FEATURE |
|
A small, rounded, knot-like swelling or wart-like protrusion. |
berry |
|
nominative |
fruit |
Indehiscent, few- to many-seeded, and derived from a single, simple or compound ovary; fleshy throughout except for the seeds. See also hesperidium, pepo. |
perennial 2 |
|
nominative |
plant |
Of perennial duration. |
velum pl. vela |
|
STRUCTURE |
|
A membranous adaxial flap or fold of vegetative tissue wholly or partly covering the sporangial cavity of a sporophyll; in Isoëtaceae. |
tree |
|
nominative |
plant |
Perennial, woody, more or less erect, relatively tall, with one or more distinct aboveground portions each with a single, relatively stout, columnar, main stem (trunk or bole) that bears branches. See also bush, frutex, shrub, subshrub, suffrutex, undershrub, woody clump. |
bud-scale scar |
|
FEATURE |
|
A scar on a stem due to abscission of a bud scale. The scar(s) encircle(s) the axis to which the bud was terminal, each single scar having an outline like that of a transverse section through the base of the bud scale that was inserted there. Sets of bud scale scars (one set per bud) usually delimit seasonal stem growth increments in temperate zone taxa. |
foliose 1 |
|
architecture |
stem |
Bearing many leaves. |
