FEATURE |
|
The more or less central point within a starch grain of intracellular origin, about which the successive layers of starch were accreted more or less symmetrically. |
|
perfect |
|
architecture |
flower |
Having functional pistil(s) and functional stamen(s) both present, thus bisexual (hermaphroditic). |
|
subpetiolar |
|
insertion |
|
Just below the point of petiole insertion. |
|
accrescent |
|
duration |
structure |
Increasing further in size after the bearing structure has become functionally mature; esp. a calyx after anthesis. |
|
symmetric(al) 2 |
|
architecture |
flower |
Having the perianth members in whorls that are actinomorphic and equal in number of members. |
|
hygroscopic |
|
architecture |
structure |
Increasing or decreasing in size according to the presence or absence of surrounding moisture, due to differential swelling or shrinking of component anatomical structures. |
|
retrorse |
|
orientation |
|
Directed generally backward, toward the proximal end of the context of reference, parallel or at an acute angle to the bearing structure. |
|
branch |
|
STRUCTURE |
|
Any higher-order division of or outgrowth from an axis, vein or veinlet when such division or outgrowth is equivalent in nature to the structure of origin. |
|
palate |
|
STRUCTURE |
|
The lower, prominent labium (lip) of a personate (gaping, ringent) corolla. |
|
chalaza pl. chalazae, chalazas |
|
STRUCTURE |
|
The basal (proximal) portion of an ovule, adjacent to its junction with the funiculus. |
|
cleistogamous |
|
reproduction |
flower |
Having the perianth remaining closed through anthesis, preventing deposit of pollen from other flowers, thus only self-pollination possible. |
|
cap cell |
|
STRUCTURE |
|
The single cell, or one of the several cells, forming the uppermost (distal) portion of an antheridial wall. |
|
thallus 1 pl. thalli |
|
STRUCTURE |
|
The vegetative portion of a shoot when not differentiated into stem and leaves; esp. in Lemnaceae. |
|
diplotegium pl. diplotegia |
|
nominative |
fruit |
A pyxis with accessory tissue adnate to the pericarp; derived from an inferior ovary. |
|
catadromous |
|
venation |
|
Having the first lateral vein in each pinna or primary segment of the frond arise from its midvein on the side toward the base of the frond, the pinnule or secondary segment that it leads to often disproportionately larger than the next distal ones. |
|
column 2 |
|
STRUCTURE |
|
A fused androecium (connate stamens) closely surrounding but free from the gynoecium; esp. in Malvaceae. |
|
gynoecium pl. gynoecia var. gynaecium |
|
STRUCTURE |
|
The pistil(s) of a single flower together with any ontogenetically equivalent or subordinate structures present, taken collectively; the total female (ovule-producing) structural complement of a single flower. It may include one to many pistils, each simple or compound. |
|
intruded |
|
placentation |
|
Upon partial septa excrescent from the wall of a compound, unilocular ovary. |
|
radicle |
|
STRUCTURE |
|
The primary root, or its primordium, in an embryo; the portion of an embryo axis that develops into the root. |
|
vascular bundle |
|
STRUCTURE |
|
A discrete strand of conducting tissues (xylem, phloem) and associated cells (e.g., cambium) within a stem or other axial structure. |
|
elliptic(al) 1 |
|
arrangement |
bundle scars |
Forming an ellipse |
|
cupule |
|
STRUCTURE |
|
A cup-like structure inserted at the base of a fruit, partially enclosing it or not; composed of a persistent, usually dried, sometimes hardened involucre, perianth, or portion thereof, the constituent parts often coalescent, yielding a unitary structure. |
