|
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. |

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. |
|
leaf-opposed |
|
position |
|
Nodal and directly opposite the leaf. |
|
unciform |
= hook-shaped |
solid shape |
|
Very slenderly elongate with a more or less straight proximal portion and a recurved terminal portion, the whole resembling a hook. |
|
trigonous |
= three-angled, triquetrous; > deltoid, obdeltoid |
solid shape |
|
Elongate with three sides that meet at acute or obtuse angles. |
|
abaxial |
= dorsal (not recommended) |
insertion |
|
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 |
insertion |
|
At or very near the developmental end or tip (apex) of a structure. |
|
lip cell |
|
STRUCTURE |
|
Either of a pair of adjacent, narrow, transversely oriented, thick-walled cells bordering the pore (stomium) of a sporangium. |
