|
Whorled and with members not overlapping, adjacent members laterally contiguous at their margins. |
|
acuminate |
= concave-tapered |
apex |
|
Gradually diminishing in width or diameter to a slender tip, the sides longitudinally concave. Corresponds with attenuate for base shape. |
|
aril 2 (strict sense) |
= arillus |
STRUCTURE |
|
An appendicular structure that wholly or partly envelops a seed and is an outgrowth from the funicle or raphe, and thus is ontogenetically derived from the placenta; usually fleshy or pulpy, sometimes spongy or tufted-capillate, often brightly colored. |
|
macrosporocarp (not recommended) |
= megasporocarp |
STRUCTURE |
|
A sporocarp that bears only macrosporangia (megasporangia). |
|
bractlet 2 |
= bracteole, prophyll(um); < bract |
STRUCTURE |
|
A second- or higher-order bract within, and subtending some portion of, an aggregate branching structure, especially when subtending a flower. |
|
nodule |
|
STRUCTURE |
|
A small nodiform (gongylodate, gongyloid, knob-shaped, knot-shaped) segment or protrusion; esp. in roots of Fabaceae (Leguminosae) and harboring nitrogen-fixing bacteria. |
|
corolla tube 1 |
|
STRUCTURE |
|
A relatively narrow, fully connate portion of a sympetalous (gamopetalous) corolla proximal to a broader portion (limb) that comprises the distinct or connate distal portions of the petals; except in bisexual or staminate disc florets of Asteraceae (Compositae). |
|
ray 1 |
< primary axis |
STRUCTURE |
|
A first-order axis within a compound umbel. |
|
scalloplet |
= crenule |
FEATURE |
|
A diminutive scallop (crena). See also sawtooth, sawtoothlet, tooth (dens), toothlet. |
|
floral cup 1 (broad sense) |
= floral tube, hypanthium (broad sense) |
STRUCTURE |
|
A complex structure comprising fused portions of the perianth and/or androecium of a flower, sometimes also including receptacular tissue; surrounding and wholly, partly, or not at all adnate to the gynoecium; subdivided morphologically into casing, collar and/or neck; sometimes bearing free distal portions of the constituent structures. |
|
solid shape |
|
CHARACTER |
|
Overall three-dimensional form or aspect(s) thereof. Overlaps conceptually with architecture, arrangement, habit, insertion, orientation, position, relief, and texture (as to thickness). |
|
stone |
= pyrene |
STRUCTURE |
|
The hard inner portion of a drupe, consisting of osseous endocarp and included seed. |
|
incurved |
|
orientation |
|
Curving adaxially. See also decurved. |
|
terete |
|
solid shape |
|
Elongate and transversely round, gradually attenuate from base to apex; attenuate-cylindric or attenuate-tubular, broadest at the base. See also obterete. |
|
gynophore |
= hypogynium; < stalk, stipe (broad sense, not recommended) |
STRUCTURE |
|
The basal portion of an ovary when constricted and stalk-like above the level of perianth insertion, bearing the main body of the pistil at its summit. |
|
indehiscent |
|
dehiscence |
|
Not splitting or forming an aperture at maturity, the contents being released for dispersal only after decay, digestion, or erosion of the structure. |
|
uncinate |
= hamate, hooked |
apex |
|
Having a recurved terminal portion that resembles a hook. |
|
bicolor(ous) |
< discolor(ous) |
coloration |
|
Having two surfaces of different colors; esp. leaves with differently colored adaxial and abaxial surfaces. |
|
abaxial |
= dorsal (not recommended) |
position |
|
On or pertaining to the side or portion of a lateral structure that faces (or would face) away from the bearing axis when (or if) the axis of the lateral structure is (or were) oriented in the same general direction as the bearing axis. |
|
apical |
< distal |
position |
|
At or very near the developmental end or tip (apex) of a structure. |
|
bifurcate |
< forked, furcate |
apex |
|
Having two terminal, antrorse branches or divisions arising from a common point or level, like the prongs of a fork. |
|
muticous |
|
apex |
|
Lacking a distinct terminal point (when one might be expected). |
|
conjugate |
= geminate, paired |
arrangement |
|
Inserted by pairs, the members of each fused or not. |
|
pithy |
= medullose |
texture |
|
Loose or spongy internally, denser and firmer externally. |
|
decussate |
|
arrangement |
|
Opposite with successive pairs radially oriented at right angles to one another, thus polystichous with four equidistant ranks. |
