|
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. |
|
vascular bundle |
|
STRUCTURE |
|
A discrete strand of conducting tissues (xylem, phloem) and associated cells (e.g., cambium) within a stem or other axial structure. |
|
elongate |
|
solid shape |
|
Longer in one dimension than in any other. |
|
andropetalous 2 |
|
derivation |
flower, perianth, corolla |
Having some or all petals derived from stamens. |
|
ray floret |
|
STRUCTURE |
|
A floret that has a zygomorphic corolla, is pistillate (either fertile or sterile) or neuter, and is borne in a radiate capitulum (head) peripheral (proximal) to the disc florets; in Asteraceae (Compositae). |
|
superposed 2 |
|
position |
buds |
Axillary in pairs, one member of each pair directly above the other. |
|
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). |
|
canalicular |
|
position |
|
Upon or otherwise directly associated with the channel of a petiole or petiolule. |
|
petiolar |
|
insertion |
|
Upon or otherwise directly associated with the petioles. |
|
sorus pl. sori |
|
STRUCTURE |
|
A cluster of sporangia borne upon a fertile frond, usually on its abaxial surface; often covered during maturation by a protective membrane, the indusium, that is an outgrowth from the epidermis; in Polypodiophyta. |
|
epigynous |
|
insertion |
perianth, calyx, corolla, androecium |
Having its proximal portion adnate to the full length of the gynoecium, the free portion thus arising from the apex of the gynoecium. See also hypogynous, perigynous. |
|
antrorse |
|
orientation |
|
Directed forward or upward, toward the distal end of the context of reference, parallel or at an acute angle to the bearing structure. |
|
revolute 1 |
|
margin |
|
Rolled inward abaxially. |
|
syncolporate |
|
architecture |
pollen grain |
Syncolpate, each groove containing a pore. |
|
laminar 1 |
|
position |
|
Upon or otherwise directly associated with the lamina (blade) of a foliaceous structure. |
|
excurrent |
|
architecture |
axis, laminar vein |
Branching laterally such that the initial axis retains its prominence over the length of the structure, the succesive orders of branches relatively smaller. See also deliquescent. |
|
areolate |
|
relief |
|
Having numerous, small, irregularly disposed, transversely angular, shallow depressions or low protrusions overall. |
|
haft |
|
STRUCTURE |
|
The narrow portion of a structure that is notably constricted. |
|
obovate |
|
plane shape |
|
Inversely ovate (egg-shaped). |
|
decussate |
|
arrangement |
|
Opposite with successive pairs radially oriented at right angles to one another, thus polystichous with four equidistant ranks. |
|
linear 2 |
|
plane shape |
|
Elongate and narrow with the sides more or less straight and parallel over most of its length. |
|
stephanocolporate |
|
architecture |
pollen grain |
Stephanocolpate, each groove containing a pore. |
|
fissure |
|
FEATURE |
|
A relatively narrow, split or crack in the outer tissue(s) of a structure. |
|
trilete |
|
architecture |
spore |
Having a triradiate tetrad scar. |
|
dichotomous |
|
architecture |
axis |
Branching by division of the apical meristem producing two coordinate but not necessarily equal derivatives from each division. |
