insertion |
perianth, calyx, corolla, androecium |
Entirely free from the gynoecium or any floral cup, arising from a level proximal or lateral to the base of the gynoecium. See also epigynous, perigynous. |
|

|
insertion |
|

|
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. |
|
inflexed |
|
orientation |
|
Bent adaxially at some point along its length. |
|
full |
|
extent |
|
Reaching from the ovary wall or pericarp to the center of the ovary or fruit and from the apex to the base of its interior, thus separating adjacent locules completely. |
|
radiant 1 |
|
architecture |
capitulum (head) |
Bearing one or more peripheral series of florets that are bisexual, pistillate, or neuter and that have relatively large actinomorphic corollas, and one or more central series of usually bisexual florets that have relatively small actinomorphic corollas; in Asteraceae (Compositae). |
|
intruded |
|
placentation |
|
Upon partial septa excrescent from the wall of a compound, unilocular ovary. |
|
perfect |
|
architecture |
flower |
Having functional pistil(s) and functional stamen(s) both present, thus bisexual (hermaphroditic). |
|
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. |
|

structure of aquatic plant |
Above the water surface. |
|
…angular 1 |
|
arrangement |
bundle scars |
Forming a figure with the number of sides indicated by the prefix. |
|
germination 2 |
|
CHARACTER |
|
The process wherein the contents of a spore begin active growth, exiting the confines of the spore wall via a pore or crack and giving rise to a gametophyte. |
|
reclining |
|
habit |
axis |
Inserted above substrate level and recurved, the distal portion procumbent. |
|
suprabracteal |
|
position |
|
Upon the axes, each directly above (distal to) and very near a point of bract insertion. |
|
spathulate |
|
plane shape |
|
See spatula-shaped, spatulate. |
|
epipterous |
|
solid shape |
|
Alate with a single terminal wing. |
|
apiculate |
|
apex |
|
Terminating abruptly in a short, slender, angular tip that is not notably harder or stiffer than the main body of the structure. See also mucronate, mucronulate. |
|
rhizoid |
|
STRUCTURE |
|
Any structure that is similar to a root in appearance and function but that is not a true root ontogenetically and anatomically, especially one produced from a gametophyte thallus. |
|
spirolobal |
|
arrangement |
cotyledons |
Incumbent and folded together transversely. |
