relief |
|
Finely foveate (pitted). |

Abruptly enlarged distally to a relatively short, terminal portion that is basically round in transverse section. |
ligule 4 |
|
STRUCTURE |
|
The distal, relatively flat portion of the zygomorphic corolla of a ligulate floret, terminating in 5 teeth or lobes; in Asteraceae (Compositae). |
valleculate |
= colpate, fossulate, furrowed, grooved, sulcate |
architecture |
|
Having one or more relatively narrow and shallow longitudinal depressions; esp. fruits of Apiaceae (Umbelliferae). |
macrosporangium pl. macrosporangia (not recommended) |
= megasporangium |
STRUCTURE |
|
A sporangium that produces megaspores. |
aculeate |
= spinose, spiny |
margin |
|
Having slender, stiff, sharp projections oriented in the general plane of the structure. |
aril 1 (broad sense) |
> arillode, arillus |
STRUCTURE |
|
An appendicular structure that wholly or partly envelops a seed and is produced from or a modification of the funicle, raphe, outer integument, or (in some Pinophyta) a subtending involucre; usually fleshy or pulpy, sometimes spongy or tufted-capillate, often brightly colored. |
macrospore (not recommended) |
= megaspore |
STRUCTURE |
|
A female spore; a spore of the larger of two types produced by the sporophytes of a heterosporous taxon; produced in a megasporangium; giving rise upon germination to a megagametophyte. |

= bracteole; < bract |
STRUCTURE |
|
A diminutive bract, or a bract that is smaller than others present. |
nodose |
= knobby, knotty |
solid shape |
|
Having nodiform (gongylodate, gongyloid, knob-shaped, knot-shaped) protrusions. See also nodulose. |
chamber (not recommended) |
= cell (not recommended), locule |
FEATURE |
|
Any structurally distinct compartment within an anther, ovary, fruit or other organ; not necessarily having any evolutionary integrity. |
paraphysis pl. paraphyses |
|
STRUCTURE |
|
An elongate, multicellular, sterile structure borne between sporangia within a sorus; in Polypodiophyta. |
corolla pl. corollae, corollas |
|
STRUCTURE |
|
Collectively, the petals of a flower, whether distinct or connate; the inner or distal envelope of a differentiated perianth, whether the other envelope (calyx) is actually present or is deemed to be absent due to evolutionary reduction. |
pollinarium pl. pollinaria |

STRUCTURE |
|
