|
dimidiate |
|
plane shape |
|
Halved, figuratively; bilaterally asymmetric, nearly or wholly lacking one side as implicitly compared with some corresponding bilaterally symmetric structure, real or imagined. |
|
antipetalous |
|
insertion |
equivalent floral structures |
Each inserted directly above or below a petal. In place of this term, the phrase "opposite the petals" is often used, but that contradicts the sense of opposite as otherwise employed (arrangement of lateral structures along an axis) and should be avoided. |
|
stipule scar |
|
FEATURE |
|
A scar on a stem or petiole due to abscission of a stipule; having an outline like that of a transverse section through the base of the stipule inserted there; variously disposed, usually in pairs, adjacent to a point of leaf insertion, sometimes confluent with the leaf scar, sometimes confluent with stipule scars associated with an opposite leaf, the two sets of scars then more or less encircling the axis. |
|
clustered 1 |
|
arrangement |
|
Disposed in one or more aggregates, the members of each inserted close together, thence widely divergent from one another. |
|
palmatipinnate |
|
architecture |
foliaceous structure |
Compound with two orders of leaflets, the first order palmate, the second pinnate. |
|
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. |
|
arcuate 1 |
|
course |
|
Curving more or less regularly in one direction. |
|
foliose 2 |
|
architecture |
thallus |
Having leaf-like lobes; in Hepaticae. |
|
mamma pl. mammae |
|
STRUCTURE |
|
A rounded-conoidal protrusion, resembling the breast of a mammal. |
|
infrafoliar |
|
position |
|
Upon the stem directly below a leaf insertion. |
|
asymmetric(al) 1 |
|
plane shape |
|
Not divisible into essentially equal halves along any line or plane. |
|
meniscoid |
|
solid shape |
|
Relatively thin with opposite, round, broad faces, one convex and one concave (as viewed externally), the circumferential edge angular or rounded; like a meniscus. See also discoid (disciform), lenticular (biconvex, lens-shaped), patelliform (kneecap-shaped). |
|
succulent |
|
texture |
|
Herbaceous and juicy, often thickened (incrassate). |
|
involucre 1 |
|
STRUCTURE |
|
One or more closely proximate whorls, or a compact spiral, of bracts immediately subtending an inflorescence, the bracts sometimes leaf-like, sometimes petaloid. |
|
pericarp |
|
STRUCTURE |
|
The portion of a fruit wall that is derived from the ovary wall; consisting of three more or less distinct tissue layers (exocarp or epicarp, mesocarp, and endocarp) that may or may not differ greatly in structure and/or function; the wall of a fruit, excluding any tissues of extra-ovarian (accessory) origin. |
|
enlarged |
|
size |
|
Unusually or unexpectedly large. |
|
monopodial |
|
architecture |
axes |
Branching laterally, each axis of each order of branches produced by a single, persistently dominant, apical meristem. See also sympodial. |
|
costal |
|
insertion |
|
Upon or otherwise directly associated with the costa(e) of a laminar structure. |
|
pilosulous |
|
pubescence |
|
Finely pilose. |
|
watery |
|
texture |
|
Liquid and weakly cohesive, flowing freely; like water. This term often implies also transparency. |
|
epulvinate |
|
architecture |
inflorescence axis, petiole |
Lacking a pulvinus. |
|
nectar |
|
SUBSTANCE |
|
An aqueous exudate of high sugar content. |
|
rhytidomal |
|
insertion |
|
Within, upon, or otherwise directly associated with the bark. |
|
acropetal |
|
development |
|
Proceeding toward the apex, thus more advanced basally or proximally than apically or distally within a given frame of reference. |
|
lateral |
|
position |
|
To, toward, at, or upon a side, not apical or basal. |
