cymulose |
|
architecture |
inflorescence |
Comprising one or more cymules. |
pliestesial |
|
duration |
plant |
Perennial and monocarpic, living several to many years before reproducing sexually, dying promptly thereafter. |
caducous |
|
duration |
structure |
Deciduous upon or immediately after emergence, with little or no evident senescence beforehand. |
annual 1 |
|
duration |
plant, stem |
Normally living one year or less; growing, reproducing, and dying within one cycle of seasons. |
oblong 2 |
|
solid shape |
|
Compressed-ellipsoid, the sides approximately parallel from near one end to near the other. See also ellipsoid(al). |
subpetiolar |
|
position |
|
Just below the point of petiole insertion. |
pappus pl. pappi |
|
STRUCTURE |
|
A set of one or more awns (aristae, bristles, setae) or scales at the summit of an inferior ovary just beneath or outside the free portion of the corolla; persisting in the fruit (cypsela) and often aiding wind or animal dispersal; in Asteraceae (Compositae). Considered by some to be an evolutionarily modified upper calyx portion, the lower portion having been incorporated into the floral tube casing adnate to the ovary wall; considered by others to be an outgrowth from the ovary wall. |
non-porous |
|
porosity |
|
Lacking vessels, the tracheary elements limited to tracheids and, sometimes, fiber-tracheids. |
pseudopetiole |
|
STRUCTURE |
|
A distinctly constricted, more or less stalk-like, proximal portion of a leaf, evolutionarily derived from the blade, the original petiole reduced to the point of absence or vestigiality; esp. in Poaceae (Gramineae). |
strict |
|
course |
|
Lacking any curve or bend. |
homochlamydeous |
|
architecture |
flower |
Having a perianth undifferentiated into distinct proximal and distal envelopes (calyx and corolla); composed of tepals, all essentially alike. |
basiscopic |
|
orientation |
subordinate structure |
Directed, facing, or pointing ("looking") toward the base of the bearing structure. |
persistent |
|
duration |
structure |
Remaining attached and conspicuous until the bearing structure reaches maturity. |
spicule |
|
STRUCTURE |
|
A small, fine, stiff, acute protrusion that resembles a little spike. |
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. |
foliose 1 |
|
architecture |
stem |
Bearing many leaves. |
superior 1 |
|
insertion |
indusium |
Inserted at or near the apex of the sorus, distal to the sporangia. |
spicy |
|
odor |
|
Pleasantly pungent, reminiscent of spices. |
foliose 2 |
|
architecture |
thallus |
Having leaf-like lobes; in Hepaticae. |
superior 2 |
|
position |
ovary |
Not enclosed to any degree by a floral tube casing, the perianth and/or androecium thus arising beneath (proximal to) it. |
unifacial |
|
architecture |
|
Having two opposite broad surfaces that are essentially similar in appearance. |
throat 1 |
|
STRUCTURE |
|
The far distal portion of a perianth, calyx, or corolla tube, or of a leaf sheath, surrounding the orifice of the tube or sheath, sometimes constricted relative to the diameter of the main body of the tube or sheath; except in disc florets of Asteraceae (Compositae). |
pyxis pl. pyxides |
|
nominative |
fruit |
Like a capsule but circumscissile, the one or more seeds being released from the locule(s) upon separation of the distal, cap-like portion of the pericarp. See also diplotegium. |
glome |
|
nominative |
inflorescence |
A rounded cluster of sessile or subsessile flowers that are inserted very close together and oriented divergently, the whole more or less hemispheric and sessile or subsessile. |
tuber |
|
STRUCTURE |
|
An enlarged, basically subterranean stem segment or thallus outgrowth containing a high proportion of storage tissue and functioning as a perennating and often vegetatively propagative structure. |
