cleistogamous |
|
reproduction |
flower |
Having the perianth remaining closed through anthesis, preventing deposit of pollen from other flowers, thus only self-pollination possible. |
stylopodium pl. stylopodia |
|
STRUCTURE |
|
A discoid enlargement at the base of the styles; esp. in Apiaceae (Umbelliferae). |
tortuous |
|
course |
|
Strongly irregular with sharp bends and/or curves. |
resinous 2 |
|
texture |
|
Having the consistency of resin. |
hydathode |
|
STRUCTURE |
|
A multicellular, anatomically distinctive structure located within a leaf at its periphery, its cells surrounding a central canal that opens to the exterior, through which water is actively discharged under humid conditions that impede the rate of transpiration; this liquid discharge is termed guttation. |
knee 2 |
|
STRUCTURE |
|
An emergent portion of an otherwise normally submerged secondary root of a wetland tree, resembling a bent human knee. |
vestiture |
|
STRUCTURE / SUBSTANCE |
|
See vesture. |
concentric |
|
position |
|
Having a center or axis of symmetry coincident with that of the context of reference. |
cyme |
|
nominative |
inflorescence |
Determinate and constituting a compound dichasium or monochasium, the flowers maturing from the center outward (i.e., the distal or inner flowers maturing first); often more or less flat-topped. See also cymule, dichasium, helicoid cyme, monochasium, rhipidium, scorpioid cyme. |
lineate 1 |
|
coloration |
|
Having very narrow, straight, clear or colored lines that contrast with the ground color. |
column 2 |
|
STRUCTURE |
|
A fused androecium (connate stamens) closely surrounding but free from the gynoecium; esp. in Malvaceae. |
ringed |
|
relief |
bark |
Fissured, mainly horizontally, with at least some of the fissures individually encircling the stem more or less completely. |
saprophytic |
|
nutrition |
plant |
Heterotrophic and obtaining essential nourishment directly from the decomposing remains of other organisms. |
opaque |
|
coloration |
|
Not transmitting light. |
simple 2 |
|
architecture |
trichome |
Unicellular and unbranched. |
mamma pl. mammae |
|
STRUCTURE |
|
A rounded-conoidal protrusion, resembling the breast of a mammal. |
pseudobulb |
|
STRUCTURE |
|
An enlarged internode of an aboveground stem, storing water and photosynthate, resembling a bulb; esp. in Orchidaceae. |
amphimictic |
|
reproduction |
taxon, plant |
Reproducing sexually. |
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. |
bract 2 (strict sense) |
|
STRUCTURE |
|
Any primary or first-order lateral structure ontogenetically and anatomically analogous with, and therefore presumably homologous with, but relatively smaller than, a leaf, especially when subtending an inflorescence, other reproductive structure, or portion thereof; putatively, an evolutionarily reduced leaf. |
squarrose |
|
orientation |
lateral structure |
Having the proximal portion appressed and the distal portion deflexed, the latter more or less perpendicular to the surface of the bearing structure. |
suprafoliar |
|
position |
|
Upon the stems, each directly above (distal to) and very near a point of leaf insertion. |
parasitic |
|
nutrition |
plant |
Heterotrophic and obtaining essential nourishment directly from other living organisms that derive no reciprocal benefit. |
discal |
|
position |
|
Upon or otherwise directly associated with the floral disc. |
anisosepalous |
|
architecture |
flower, perianth, calyx |
Having sepals unequal in size and/or shape. |
