epiphyllous |
|
position |
|
Upon the leaves, or partially adnate thereto and apparently arising therefrom. |
naked 1 |
|
architecture |
|
Lacking a covering that might have been expected. |
catadromous |
|
venation |
|
Having the first lateral vein in each pinna or primary segment of the frond arise from its midvein on the side toward the base of the frond, the pinnule or secondary segment that it leads to often disproportionately larger than the next distal ones. |
semicircular |
|
arrangement |
bundle scars |
Forming an incomplete circle, like the letter C. |
non-porous |
|
porosity |
|
Lacking vessels, the tracheary elements limited to tracheids and, sometimes, fiber-tracheids. |
chambered |
|
architecture |
pith |
Interrupted by cavities that are more or less regularly spaced along the axis and that result from disintegration of tissue prior to axis maturity. |
obterete |
|
solid shape |
|
Inversely terete. |
deliquescent 1 |
|
architecture |
axis, laminar vein |
Branching laterally and repeatedly such that the initial axis loses its prominence over the length of the structure and seems to dissolve into the succesive orders of branches. See also excurrent. |
lineolate 2 |
|
relief |
|
Finely lineate, the depressions or protrusions short and often irregularly oriented. |
fixation |
|
CHARACTER |
|
Mode of attachment to a supporting structure. |
radiate 1 |
|
architecture |
capitulum (head) |
Bearing one or more peripheral series of florets that are pistillate (either fertile or sterile) or neuter and that have zygomorphic corollas, and one or more central series of bisexual or functionally staminate florets that have actinomorphic corollas; in Asteraceae (Compositae). |
homochlamydeous |
|
architecture |
flower |
Having a perianth undifferentiated into distinct proximal and distal envelopes (calyx and corolla); composed of tepals, all essentially alike. |
diffuse |
|
architecture |
plant, stem |
Having branches remote and divergent to divaricate. |
suprafoliar |
|
position |
|
Upon the stems, each directly above (distal to) and very near a point of leaf insertion. |
flaccid |
|
texture |
|
Limp, sometimes appearing withered or shrunken. See also tumid (swollen, turgid). |
cleistogamous |
|
reproduction |
flower |
Having the perianth remaining closed through anthesis, preventing deposit of pollen from other flowers, thus only self-pollination possible. |
bifacial |
|
architecture |
|
Having two opposite broad surfaces that differ distinctly in appearance. |
fluted |
|
solid shape |
|
Having rounded to angular longitudinal grooves. |
spongy |
|
texture |
|
Soft, light, discontinuous but cohesive, and somewhat resilient. |
woody clump |
|
nominative |
plant |
An aggregate of woody main stems that arise from belowground organs derived from a single progenitor; the members of a clump are individually tree- or shrub-like and sometimes become physically separate over time. See also bush, frutex, shrub, subshrub, suffrutex, tree, undershrub. |
inferior 2 |
|
position |
ovary |
Wholly enclosed by a floral tube casing, the distal portions of the perianth and/or androecium thus arising from its apex. |
parietal |
|
placentation |
|
Upon the inner wall surface of a unilocular ovary, thus peripheral within the locule. |
tetradynamous |
|
architecture |
flower, androecium |
Diadelphous with four stamens in one set and two in the other. See also didynamous. |
conoidal |
|
solid shape |
|
Generally but not strictly conic. |
bursicle |
|
STRUCTURE |
|
A pouch- or flap-like protrusion from the stigma that encloses the caudicle of a pollinium. |
