gynomonoecious |
|
reproduction |
taxon |
Having all plants with both bisexual flowers and pistillate ones. |
plicate 1 |
|
aestivation |
|
Valvate with each member strongly infolded longitudinally. |
amphibious |
|
habit |
plant |
Able to live in either aquatic or terrestrial habitats; e.g., adapted to periodic inundation on floodplains. |
aquatic |
|
habit |
plant |
Growing in water. |
gamophyllous |
|
architecture |
plant, shoot axis, involucre |
Having pairs or whorls of leaves or bracts that are connate at their edges. |
flanged |
|
solid shape |
|
Having a relatively broad circumferential rim or ridge that protrudes laterally. |
aristate 2 |
|
apex |
pappus scale |
Terminating in one or more awn- or bristle-like appendages. |
peripheral |
|
position |
|
Upon or otherwise directly associated with the outer surfaces or regions of a three-dimensional structure. Although use of this term in two-dimensional contexts is technically correct, traditionally the term marginal is preferred in such cases. |
lumen pl. lumina |
|
FEATURE |
|
A space enclosed by the wall(s) or membrane(s) of a structure. |
subtending |
|
insertion |
|
Arising from the axis just below and very near to the base of some other specified lateral structure. This term is meaningless if the structure that is subtended is not indicated. |
glomerulate |
|
architecture |
inflorescence |
Comprising one or more glomerules; esp. in Asteraceae (Compositae). |
subtending |
|
position |
|
Arising from the axis just below and very near to the base of some other specified lateral structure. This term is meaningless if the structure that is subtended is not indicated. |
glomerule |
|
nominative |
inflorescence |
A compact cluster of capitula (heads), sometimes subtended by an involucre; thus, a compound capitulum (head); esp. in Asteraceae (Compositae). |
callus |
|
FEATURE |
|
A small, relatively hard covering, outgrowth, or swelling of tissue; esp. in axes of grass (Poaceae) inflorescences just distal to points of eventual disarticulation. |
umbel |
|
nominative |
inflorescence |
Pedunculate, determinate or indeterminate, simple or compound and apparently polychotomous, with one or more pedicellate flowers terminating each ultimate axis, the pedicels of each such floral set and the branches (rays) arising from each axial subdivision diverging from each other like the ribs of an umbrella, the whole plane, convex or concave distally. |
synandrous |
|
architecture |
flower, androecium |
Having the stamens connate. |
suprabracteal |
|
insertion |
|
Upon the axes, each directly above (distal to) and very near a point of bract insertion. |
rhachis |
|
STRUCTURE |
|
See rachis. |
smooth 1 |
|
relief |
|
Even or unrelieved overall. Strictly applied, this term refers only to the surface proper; however, it is often used to mean glabrous as well. |
foliar |
|
position |
|
Upon or otherwise directly associated with the leaves. |
terminal |
|
insertion |
|
Apical and with the same developmental axis as the whole, of which it is the distalmost portion or appendage. |
wiry |
|
architecture |
axis |
Relatively very narrow and elongate, tough, and resiliently flexible. |
intercostal |
|
position |
|
Between the costae. |
rounded |
|
base |
|
Convex overall and more or less regularly curved. |
basipetal |
|
development |
|
Proceeding toward the base, thus more advanced apically or distally than basally or proximally within a given frame of reference. |
