|
connective |
|
STRUCTURE |
|
The tissue between and joining the laterally opposed thecae of an anther, connecting them with the distal end of the staminal filament when the latter is present. |
|
spinulose |
|
architecture |
|
Finely spinose. |
|
coronal |
|
position |
|
Upon or otherwise directly associated with the corona. |
|
deciduous 2 |
|
habit |
plant |
Perennial and having all leaves separating and falling away during a particular portion of the yearly cycle, especially the autumn or the dry season, between growing seasons. Semantically, this term is properly applied only to the entity that falls, not to the structure that it separates and falls from; in traditional usage, though, the term has been applied to trees and other perennial plants that shed all their leaves at some time during the yearly cycle. |
|
oblate |
|
solid shape |
|
Symmetrically elongate and broader than long perpendicular to the developmental or polar axis. |
|
node |
|
STRUCTURE |
|
One of the evident sectors of a stem that occur sequentially along its length and from which leaves (megaphylls) and lateral branches arise exogenously. The anatomy of nodes differs from, but is not abruptly distinct longitudinally from, that of the intervening sectors (internodes), with which it is smoothly confluent and from which is distinguished by the lateral transit and egress of vascular traces interconnecting the stem and the leaves and branches that it bears. |
|
disc 2 var. disk |
|
STRUCTURE |
|
Collectively, the disc florets of a capitulum (head), or the surface presented by them. |
|
synstemonous |
|
architecture |
flower, androecium |
Having two or more stamens, some or all of them connate. |
|
endophytic |
|
habit |
|
Growing within some portion of another, unrelated, living plant. |
|
trichotomocolpate |
|
architecture |
pollen grain |
Having a triradiate surficial groove (colpus). |
|
explosive |
|
dehiscence |
|
Opening abruptly with almost instantaneous aperture formation and release of accumulated structural tensions, the contents thus forcibly expelled. |
|
episepalous |
|
position |
|
Upon the sepals, or partially adnate thereto and apparently arising therefrom. |
|
piliferous |
|
apex |
|
Having a distinct, fine, weak, hair-like portion or protrusion. |
|
fissure |
|
FEATURE |
|
A relatively narrow, split or crack in the outer tissue(s) of a structure. |
|
perigynium 1 pl. perigynia |
|
STRUCTURE |
|
Two whorls of bracts, scales or setae immediately subtending the ovary, sometimes cupulate (cup-shaped) or ampulliform (flask-shaped, lageniform) and investing the fruit (achene); in Cyperaceae. |
|
versatile |
|
fixation |
|
Attached in a manner allowing free rotation and declination. |
|
perigynium 2 pl. perigynia |
|
STRUCTURE |
|
A phyllary (involucral bract) or palea (pale, palet) that fully encloses a cypsela; in Asteraceae (Compositae). |
|
polygamodioecious |
|
reproduction |
taxon |
Basically dioecious but with some plants bearing some bisexual flowers. |
|
planoconcave |
|
solid shape |
|
Relatively thin with opposite broad faces, one plane and one concave. |
|
proliferous |
|
reproduction |
plant, structure |
Bearing plantlets, as from the leaf margin in some Kalanchoë (Crassulaceae). |
|
hemispheric(al) |
|
solid shape |
|
Half-spheric(al); broadest at the base and uniformly rounded to the apex, circular in any transverse section, and half-circular in any median longitudinal section. |
|
bract 2 (strict sense) |
|
STRUCTURE |
|
Any primary or first-order lateral structure ontogenetically and anatomically analogous with, and therefore presumably homologous with, but relatively smaller than, a leaf, especially when subtending an inflorescence, other reproductive structure, or portion thereof; putatively, an evolutionarily reduced leaf. |
|
raceme |
|
nominative |
inflorescence |
An elongate, unbranched main axis bearing pedicellate flowers inserted singly along it. |
|
biennial 1 |
|
duration |
plant, stem |
Normally living two years; germinating or forming and growing vegetatively during one cycle of seasons, then reproducing sexually and dying during the following one. |
|
ridged |
|
solid shape |
|
Having one or more ridges; esp. fruits of Apiaceae (Umbelliferae). |
