|
deciduous 1 |
|
duration |
structure |
Separating and falling away from the bearing axis, organ or plant prior to senescence of the latter, usually by developing an anatomically distinct, transverse, basal zone of cells (abcission layer), where separation occurs. See also seasonally deciduous. |

|
position |
|
Upon and surrounding the stem. |
|
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). |
|
praemorse |
|
apex |
|
Truncate with the distal margin irregular or ragged, as if chewed. |
|
unifacial |
|
architecture |
|
Having two opposite broad surfaces that are essentially similar in appearance. |
|
banded |
|
coloration |
|
Broadly striped; having one or more elongate, relatively broad and, when multiple, more or less parallel, areas of contrasting hue and/or intensity. |
|
heterotrophic |
|
nutrition |
plant |
Dependent upon other organisms for some or all of its essential nourishment, assimilating such materials either directly from the other organisms, living or dead, or from their products. |
|
secund 1 |
|
architecture |
inflorescence |
Having the pedicels oriented such that the main bodies of all the flowers lie to one side of the bearing axis. |
|
floral |
|
insertion |
|
Upon, within, or associated with the flowers. |
|
pseudopetiolate |
|
architecture |
leaf |
Having a distinctly constricted, more or less stalk-like, proximal portion that is evolutionarily derived from the blade, the original petiole reduced to the point of absence or vestigiality; esp. in Poaceae (Gramineae). |
|
collar 1 |
|
STRUCTURE |
|
The free portion (if any) of a floral tube, distal to its casing and/or neck when one or both is/are present. |
|
septifragal |
|
dehiscence |
fruit |
Splitting through the exterior wall suture(s) but not the septum(-a), the valves of the wall then separating from the septum(-a) and the locules thus opened directly to the outside. |
|
syngenesious |
|
fusion |
flower, androecium |
Having the anthers connate or coherent and forming a ring. |
|
akene |
|
nominative |
fruit |
See achene. |
|
matted |
|
habit |
plants |
Growing in extensive, low, dense aggregations, sometimes with the stems of different plants intertwined. |
|
bulb |
|
STRUCTURE |
|
A thickened underground perennating structure consisting of a stem with numerous closely proximate nodes bearing many tightly imbricate, thickened, often fleshy, foliaceous organs containing large amounts of stored food, usually in the form of starch; the whole usually enveloped and protected by imbricated scarious or fibrous foliaceous organs. |
|
integumentary |
|
derivation |
aril |
Produced from or a modification of one or both seed integuments. |
|
elater 1 |
|
STRUCTURE |
|
An elongate cell with a helical, hygroscopic thickening in its wall, contained within a sporangium, expanding and contracting with changes in humidity and aiding dispersal of the spores; esp. in Hepaticae. |
|
androecial tube |
|
STRUCTURE |
|
The tubular portion of an androecium in which the component structures have fused with one another laterally over part or all their lengths. |
|
microsporocarp |
|
STRUCTURE |
|
A sporocarp that bears only microsporangia. |
|
corm |
|
STRUCTURE |
|
A short, thickened, solid, usually subterranean, sometimes fleshy stem base containing stored carbohydrates and serving as a perennating organ. |
