unisexual |
|
reproduction |
|
Having functional reproductive structures of only one sex. See also imperfect, pistillate, staminate. |
septal |
|
position |
|
Upon or otherwise directly associated with the septum or septa. |
paraphysis pl. paraphyses |
|
STRUCTURE |
|
An elongate, multicellular, sterile structure borne between sporangia within a sorus; in Polypodiophyta. |
incurved |
|
orientation |
|
Curving adaxially. See also decurved. |
continuous 1 |
|
architecture |
inflorescence |
Having the flowers or branch units distributed evenly along the axis, with no significant interruption. |
pseudobulb |
|
STRUCTURE |
|
An enlarged internode of an aboveground stem, storing water and photosynthate, resembling a bulb; esp. in Orchidaceae. |
reproduction |
|
CHARACTER |
|
Type, morphology, disposition, function and/or dissemination of reproductive structures. |
geminicolpate |
|
architecture |
pollen grain |
Having four or more surficial grooves (colpi) disposed in pairs. |
eccentric |
|
position |
|
Having a center or axis of symmetry not coincident with that of the context of reference. |
decompound |
|
architecture |
|
Comprising two or more orders of equivalent substructural entities; multiply compound. |
lemma pl. lemmata, lemmas |
|
STRUCTURE |
|
The proximal bract of the (usually) two that immediately subtend the flower in a grass (Poaceae) floret; the other is the palea. |
column 2 |
|
STRUCTURE |
|
A fused androecium (connate stamens) closely surrounding but free from the gynoecium; esp. in Malvaceae. |
polygamous |
|
reproduction |
taxon |
Having both bisexual and unisexual flowers, borne on the same or on different plants. |
salt-excreting |
|
exudation |
|
Accumulating salt and discharging it directly to the exterior in a concentrated aqueous solution, the salt then crystallizing on the exterior following evaporation of the fluid medium; when salt-excreting glands are indicated in the nominative, usually they are called simply salt glands. |
diaphragmed |
|
architecture |
pith |
Uninterrupted by cavities but heterogeneous in texture at axis maturity, with sectors of spongy tissue separated by relatively thin transverse plates of denser tissue that occur at the nodes or are otherwise regularly spaced along the axis. |
stilt root |
|
STRUCTURE |
|
A relatively stout or strong adventitious root arising from a woody stem branch and extending downward directly toward the substrate, within which it ultimately becomes anchored, thus supporting the branch of origin; as in some Ficus (Moraceae). |
disciform 2 |
|
architecture |
capitulum (head) |
Bearing one or more peripheral series of florets that are usually pistillate and that have relatively slender actinomorphic corollas, and one or more central series of florets that are bisexual or functionally staminate and that have relatively broader actinomorphic corollas; in Asteraceae (Compositae). |
hirsute |
|
pubescence |
|
Bearing coarse, rough, elongate, more or less erect, capillate trichomes. See also hirtellous. |
acetabuliform |
|
solid shape |
|
Transversely circular, broader than long, widest near or at the middle, relatively thin-walled, the hollow interior open distally; like a shallow bowl with strongly incurved sides. |
…faced |
|
solid shape |
|
Having relatively large, flat or shallowly curved portions of the external surface that are bounded by more or less distinct angular discontinuities in that surface, of the number indicated by the prefix; as in three-faced. |
epidermal cell |
|
STRUCTURE |
|
Any of the unspecialized cells of an epidermis; i.e., any other than stomatal guard cells or cells directly associated with trichomes. While the latter specialized cells are also properly epidermal cells, they are treated separately for descriptive purposes and, for the sake of convenience, use of the general term is restricted to the unspecialized cells that constitute the bulk of an epidermis. |
striped |
|
coloration |
|
Having one or more elongate, relatively narrow and, when multiple, more or less parallel, areas of contrasting hue and/or intensity. |
bursicle |
|
STRUCTURE |
|
A pouch- or flap-like protrusion from the stigma that encloses the caudicle of a pollinium. |
aromatic |
|
odor |
|
Having a distinct odor; usually restricted to pleasant odors. |
perennial 2 |
|
nominative |
plant |
Of perennial duration. |
