arcuate 2 |
|
plane shape |
|
Elongate and more or less regularly curved from one end to the other, one side convex, the opposite concave. |
involucel |
|
STRUCTURE |
|
One or more closely proximate whorls of bractlets (bracteoles, prophylls) immediately subtending (below or outside) a subordinate portion of an inflorescence that is subtended as a whole by an involucre, the bractlets often leaf-like, sometimes petaloid. |
stilt-rooted |
|
architecture |
plant |
Bearing and partly supported by stilt roots. |
obovate |
|
plane shape |
|
Inversely ovate (egg-shaped). |
staminal |
|
insertion |
|
Upon or otherwise directly associated with the stamens. |
herbaceous 1 |
|
habit |
plant |
Having no significant degree of secondary growth in any part of the shoot, which thus does not develop woody (lignified) tissue. |
beard |
|
STRUCTURE |
|
A growth of relatively long, erect, flexible, capillary trichomes from one or more limited sectors of a structure's surface. |
strobiloid |
|
architecture |
flower |
Characterized by a general lack of adnation among the different sets of basic floral structures, any significant degree of fusion limited to connation within sets, thus with ovary(ies) superior and lacking a floral tube. |
pappose |
|
architecture |
flower, fruit |
Bearing a pappus; esp. in Asteraceae (Compositae). |
puberulent |
|
pubescence |
|
Finely pubescent in the restricted sense of that term. |
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. |
gummy |
|
texture |
|
Highly viscous and sticky, liquid or more or less deformably solid, sometimes more or less elastic. |
indusium pl. indusia |
|
STRUCTURE |
|
A protective membrane that is an outgrowth from the epidermis and covers a sorus during its maturation; in Polypodiophyta. |
scape |
|
STRUCTURE |
|
A leafless, essentially naked, inflorescence-bearing stem (or peduncle) arising directly from a caudex or rhizome, its point of insertion slightly beneath, at, or slightly above the substrate surface. |
enzymatic |
|
exudation |
|
Secreting a digestive exoenzyme; in carnivorous plants. |
sympodial |
|
architecture |
axes |
Branching laterally, each axis of each apparent order of branches comprising a series of laterally derived segments each of which functioned in turn as the distal leader, the apical meristem of each segment dominant until supplanted by that of the next. See also monopodial. |
muticous |
|
apex |
|
Lacking a distinct terminal point (when one might be expected). |
coronal |
|
position |
|
Upon or otherwise directly associated with the corona. |
superposed 2 |
|
insertion |
buds |
Axillary in pairs, one member of each pair directly above the other. |
lamellate |
|
apex |
laminar structure |
Having two small terminal plates of tissue closely parallel to one another and perpendicular to the plane of the lamina. |
nodulose |
|
solid shape |
|
Diminutively nodose; esp. roots of Fabaceae (Leguminosae), the nodules harboring nitrogen-fixing bacteria. |
glandular 2 |
|
exudation |
|
Anatomically distinct and producing and exuding a particular substance. |
xerocleistogamous |
|
reproduction |
flower |
Normally chasmogamous but facultatively cleistogamous during drier than normal periods. |
diplostemonous |
|
architecture |
flower, androecium |
Having the stamens dicyclic, the proximal whorl with members directly above the sepals, the distal whorl with members directly above the petals. See also obdiplostemonous. |
fixation |
|
CHARACTER |
|
Mode of attachment to a supporting structure. |
