|
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. |
|
cylindric(al) |
|
solid shape |
|
Solid and transversely round with a more or less uniform diameter, the ends blunt. |
|
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. |
|
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. |
|
cauline |
|
insertion |
|
Upon, arising from, or otherwise directly associated with the stem. |
|
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. |
|
aerial |
|
location |
|
Above ground or water level. |
|
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. |
|
sapwood |
|
STRUCTURE |
|
That portion of the wood (xylem) of a stem or root whose cells are still living and functional; concentric about the heartwood once the latter has begun to form. |
|
indeterminate |
|
development |
|
Having the lateral (peripheral, basal, or proximal) portions differentiating first and the terminal (central, apical, or distal) portion later, development thus proceeding sequentially upward or inward. |
|
isostemonous |
|
architecture |
flower, androecium |
Having the stamens essentially alike in size and shape. |
|
smooth 2 |
|
relief |
bark |
Unfissured; not cracked or split to any significant degree. |
|
levering |
|
habit |
trichome |
Forming part of a pappus and reflexing at maturity, thus helping to loosen the individual fruit (cypsela) from the capitulum (head); in Asteraceae (Compositae). |
|
siliceous |
|
texture |
epidermis, trichome |
Containing deposits of silica, thus hardened and abrasive. |
|
aristate 2 |
|
apex |
pappus scale |
Terminating in one or more awn- or bristle-like appendages. |
|
silicle |
|
nominative |
fruit |
Like a silique, but only slightly longer than broad to broader than long; esp. in Brassicaceae (Cruciferae), Capparaceae. |
|
aromatic |
|
odor |
|
Having a distinct odor; usually restricted to pleasant odors. |
|
spinescent |
|
architecture |
|
Becoming spinose. |
|
staminodial |
|
position |
|
Upon or otherwise directly associated with the staminodes. |
|
subtending |
|
position |
|
Arising from the axis just below and very near to the base of some other specified lateral structure. This term is meaningless if the structure that is subtended is not indicated. |
|
diplecolobal |
|
arrangement |
cotyledons |
Incumbent but with the cotyledons folded together twice or more, the folds transverse. |
