Bearing mamillae. |
tuberous 2 |
|
architecture |
structure |
Resembling a tuber in shape and texture, but not ontogenetically such; esp. roots. |
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. |
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. |
smooth 2 |
|
relief |
bark |
Unfissured; not cracked or split to any significant degree. |
dichlamydeous |
|
architecture |
flower |
Having a perianth differentiated into a distinct calyx (sepals) and corolla (petals). |
involucre 2 |
|
STRUCTURE |
|
One or more closely proximate whorls, or a compact spiral, of bracts (phyllaries) surrounding (proximal to) the compound receptacle (torus) and florets of a capitulum (head); in Asteraceae (Compositae). |
actinodromous |
|
venation |
|
Having three or more primary veins that diverge radially from a point at or above the base of the blade and run toward the margin, reaching it or not. |
alternate 2 |
|
arrangement |
structures in multiple whorls |
Having those of each whorl staggered radially in relation to those of the adjacent whorl(s). |
spinescent |
|
architecture |
|
Becoming spinose. |
laminar 2 |
|
solid shape |
|
Relatively very thin with parallel opposite broad faces, the whole plane or variously curved. Structures to which this term, along with any other three-dimensional ones, is applicable are often also described as though only two-dimensional, using terms that are implicitly understood to refer only to the outline of the broad faces. |
retuse |
|
apex |
|
Round overall with an obtuse terminal sinus. |
secund 2 |
|
architecture |
stem |
Having the petioles oriented such that the main bodies of all the leaves lie to one side of the bearing stem. |
velum pl. vela |
|
STRUCTURE |
|
A membranous adaxial flap or fold of vegetative tissue wholly or partly covering the sporangial cavity of a sporophyll; in Isoëtaceae. |
angular |
|
plane shape |
|
Having sides that meet at acute or obtuse angles. |
indehiscent |
|
dehiscence |
|
Not splitting or forming an aperture at maturity, the contents being released for dispersal only after decay, digestion, or erosion of the structure. |
umbilicate |
|
solid shape |
|
Having a relatively small, transversely round, central depression in an essentially round broad face. |
legume |
|
nominative |
fruit |
Dry, septicidal, one-loculed and derived from a single, superior, simple ovary; dehiscing along two sutures, one abaxial, one adaxial; in Fabaceae (Leguminosae). See also loment. |
oblanceolate |
|
plane shape |
|
Inversely lanceolate (lancehead-shaped). |
polygamous |
|
reproduction |
taxon |
Having both bisexual and unisexual flowers, borne on the same or on different plants. |
flanged |
|
plane shape |
|
Having a relatively broad circumferential rim or ridge that protrudes laterally. |
V-form |
|
arrangement |
bundle scars |
Disposed in an open-ended triangular pattern, like the letter V. |
prophyllar |
|
insertion |
|
Upon or otherwise directly associated with the prophylls (bracteoles, bractlets). |
muriculate |
|
relief |
|
Finely muricate. |
eucamptodromous |
|
venation |
|
Having a single median primary vein that branches to either side along the length of the lamina, the secondary veins upwardly arcuate, gradually becoming indistinct interior to the margin, and serially interconnected by cross-branches without formation of marginal loops. |
