aquatic |
|
habit |
plant |
Growing in water. |
style |
|
STRUCTURE |
|
A narrow, usually elongate, ontogenetically distal portion of a simple or compound pistil, overtopping the ovary and bearing one or more stigmas; arising from the summit of the ovary, but sometimes apparently from its base at maturity to ontogenetic displacement from its primordial distal position. In a compound pistil the various simple (carpellary) components of the style(s) may not be connate over their entire lengths; the pistil is then regarded as having a branched style or styles. |
basicaulous |
|
insertion |
|
At or very near the stem base. |
muricate |
|
relief |
|
Having short, hard, more or less acute, transversely round protrusions overall. See also muriculate. |
syncolpate |
|
architecture |
pollen grain |
Having two or more fused or confluent surficial grooves (colpi). |
embryotega pl. embryotegae, embryotegas |
|
STRUCTURE |
|
A small, hardened, lid-like portion of the testa (seed coat) at the micropyle of some seeds, detaching at germination. |
axile |
|
placentation |
|
Upon the central axis of a compound, plurilocular ovary. |
odor |
|
CHARACTER |
|
Olfactory stimulation. |
suprabasal |
|
position |
|
Just above the base of the structure in point. |
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. |
dyadal |
|
arrangement |
pollen |
Cohering and shed in pairs, each tetrad having separated into halves. |
partial |
|
extent |
|
Not reaching fully from the ovary wall or pericarp to the center of the ovary or fruit and/or from the apex to the base of its interior, thus not completely separating adjacent locules, which are recognized and delimited by extrapolating from the incomplete septal boundary(ies), the ovary or fruit nonetheless effectively unilocular. |
tiered |
|
arrangement |
|
In two or more rows that are arrayed one above another. |
epiphyllous |
|
position |
|
Upon the leaves, or partially adnate thereto and apparently arising therefrom. |
phanerocotyloid |
|
germination |
seed |
Having the cotyledon(s) emerging from the seed coat. |
perianth |
|
STRUCTURE |
|
Collectively, all the sterile, primary, lateral organs (tepals, or sepals and/or petals) of a flower; inserted upon the floral axis immediately beneath (proximal to) the reproductive organs (androecium and/or gynoecium) and surrounding them, often protectively; lacking in some taxa; the individual members typically laminar and more or less foliaceous; widely regarded as consisting of the evolutionarily modified leaves of a fertile shoot; the constituent members undifferentiated with respect to one another, or else differentiated into more or less distinct floral envelopes (calyx and corolla), one or the other of which is deemed lacking in some taxa due to evolutionary reduction following differentiation. |
utricle |
|
nominative |
fruit |
Dry, indehiscent, one-seeded and with the pericarp thin and free from the seed; derived from a single, superior, simple ovary. |
placenta pl. placentae, placentas |
|
STRUCTURE |
|
An ovule-bearing zone of the tissue surface bordering an ovary locule; of merely topographic, not histological, significance; may be a part of the ovary wall proper or an extension from it, or a part of the central axis of the ovary or an extension from it. |
cochlear |
|
aestivation |
|
Imbricate with one member larger than and exterior to the others, parallel to one that is internal to all the others, strongly incurved, and enclosing the others. |
floating 2 |
|
location |
|
At or upon the surface of water. |
pseudolamina pl. pseudolaminae |
|
STRUCTURE |
|
The expanded part of a phyllode (phyllodium), resembling a blade but evolutionarily derived from the petiole. |
ramal |
|
insertion |
|
Upon or otherwise directly associated with the stem branches. |
pyramidal |
|
solid shape |
|
Transversely triangular or polygonal, broadest at the base and regularly attenuate to an angular apex, all faces essentially plane. |
repand |
|
margin |
|
Gently or shallowly sinuate. |
integument |
|
STRUCTURE |
|
A distinct layer of tissue that encloses and serves to protect the other tissues of an organ, especially a seed. |
