STRUCTURE |
|
A small bladder-like part consisting of an enclosing wall or covering and an empty or fluid-filled interior, sometimes turgid; esp. in citrus fruits (hesperidia). |
|
scar |
|
FEATURE |
|
A discontinuity in surface color and/or relief due to abscission of a structure formerly borne there. |
|
asymmetric(al) 1 |
|
plane shape |
|
Not divisible into essentially equal halves along any line or plane. |
|
replicate |
|
vernation |
|
Each with the distal portion of its blade recurved, paralleling and contiguous with the proximal portion. |
|
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. |
|
valvate 3 |
|
dehiscence |
anther |
Poricidal with the pores formed by the raising of small flaps (valves) in the exterior wall. |
|
intercostal |
|
insertion |
|
Between the costae. |
|
cell 1 |
|
STRUCTURE |
|
Any of the basic structural/functional units that collectively or individually make up the various tissues of a plant; comprising, at least while physiologically active, a nucleus with included genetic material (chromosomes), a surrounding cytoplasm with included organelles (e.g., ribosomes, mitochondria, plastids), an enclosing membrane, and an exterior cellulosic wall. |
|
beard |
|
STRUCTURE |
|
A growth of relatively long, erect, flexible, capillary trichomes from one or more limited sectors of a structure's surface. |
|
lacuna pl. lacunae |
|
FEATURE |
|
A hole or cavity; an empty space surrounded by tissue in two or three dimensions. |
|
cleistogamous |
|
reproduction |
flower |
Having the perianth remaining closed through anthesis, preventing deposit of pollen from other flowers, thus only self-pollination possible. |
|
jacket cell |
|
STRUCTURE |
|
Any of the cells forming the portion of an antheridial wall between the basal cells and the cap cell(s). |
|
soboliferous |
|
architecture |
plant |
Having several, loosely clumped, principal stems that arise from a common underground stem system, each distinct above ground level. |
|
…ciliate |
|
architecture |
|
Bearing the number of cilia indicated by the prefix. |
|
silique |
|
nominative |
fruit |
Dry, septifragal, two-loculed and derived from a single, superior, compound ovary; much longer than broad; dehiscing along two sutures, one adaxial, one abaxial, leaving a single persistent septum (replum) after the two valves of the pericarp have fallen away; esp. in Brassicaceae (Cruciferae), Capparaceae. See also silicle. |
|
spinose 1 |
|
apex |
|
Terminating in a rigid, tapering, sharp continuation of the central primary vein. See also spinulose. |
|
corolla tube 1 |
|
STRUCTURE |
|
A relatively narrow, fully connate portion of a sympetalous (gamopetalous) corolla proximal to a broader portion (limb) that comprises the distinct or connate distal portions of the petals; except in bisexual or staminate disc florets of Asteraceae (Compositae). |
|
mixed-craspedodromous |
|
venation |
|
Having a midvein that branches to either side along the length of the lamina, the secondary veins running thence toward the margin, some becoming indistinct before reaching it, others terminating there. |
|
cypsela pl. cypselae |
|
nominative |
fruit |
Like an achene but derived from an inferior, bicarpellate ovary and with accessory perianth tissue adnate to the pericarp; esp. in Asteraceae (Compositae). |
|
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. |
|
ovary |
|
STRUCTURE |
|
The proximal portion of a pistil (either simple or compound) within which the ovules are borne; usually of somewhat greater diameter and/or volume than the remainder of the pistil. |
|
emersed |
|
location |
structure of aquatic plant |
Above the water surface. |
|
oil-secreting |
|
exudation |
|
Producing and exuding an oily substance, often aromatic; when oil-secreting glands are indicated in the nominative, often they are called simply oil glands. |
|
exfoliating |
|
relief |
bark |
Shallowly and distantly fissured, falling away in thin, relatively large patches or sheets. |
|
epipterous |
|
solid shape |
|
Alate with a single terminal wing. |
