rosette |
|
STRUCTURE |
|
A set of leaves that are strongly congested and disposed in radial symmetry about the main stem at or very near its base, seeming to arise at the same level and often overlapping laterally; esp. the overwintering leaves of perennial herbs. |
basal cell |

STRUCTURE |
|
Any of the ring of cells forming the lowermost (proximal) portion of an antheridial wall. |
sectile |

architecture |
pollinium |
Having partially separated sectors, as though cut. |
involucre 1 |
|
STRUCTURE |
|
One or more closely proximate whorls, or a compact spiral, of bracts immediately subtending an inflorescence, the bracts sometimes leaf-like, sometimes petaloid. |
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. |
infructescence 1 |
|
STRUCTURE |
|
A mature (fruiting) inflorescence (static sense). |
spongy |
|
texture |
|
Soft, light, discontinuous but cohesive, and somewhat resilient. |
accessory cell |
|
STRUCTURE |
|
One of the cytologically distinctive epidermal cells that are sometimes present in a stomate and that surround and are regularly oriented in relation to the guard cells. |
bigeminate |
|
architecture |
foliaceous structure |
Compound with two orders of leaflets, each order bifoliolate. |
septicidal |
|
dehiscence |
fruit |
Splitting longitudinally into or through the suture(s) in the outer wall and, if present, through the septum(-a) between locules, the latter thus opened indirectly to the outside. |
anatropous |
|
orientation |
ovule |
Having the funiculus distally recurved and the (straight) ovule lying beside and parallel to the proximal portion of the funiculus, to which it may be adnate or adherent, the micropyle facing the ovary wall (placenta). |
sterile |
|
reproduction |
plant, reproductive structure |
Not producing functional spores, gametes, pollen, ovules, seeds, or other propagules. |
microphyll |
|
STRUCTURE |
|
A small, lateral, leaf-like enation that, evolutionarily, is not a true leaf, i.e., whose vasculature, if any, consists of only a single median strand not ontogenetically integral with the vasculature of the bearing stem and not associated with leaf gaps in the stele of the stem; in Bryophyta, Psilotophyta, Lycopodiophyta, Equisetophyta. |
adenopetalous 1 |
|
architecture |
flower, perianth, corolla |
Having petals produced from glandular structures. |
apostemonous |
|
architecture |
flower, androecium |
Having two or more distinct stamens; having the stamens unfused. |
matted |
|
habit |
plants |
Growing in extensive, low, dense aggregations, sometimes with the stems of different plants intertwined. |
nectariferous |
|
exudation |
|
Producing and secreting nectar; when glands are nectariferous, they are usually indicated nominatively as nectaries. |
didynamous |
|
architecture |
flower, androecium |
Diadelphous with two stamens in each set. See also tetradynamous. |
symmetric(al) 1 |
|
architecture |
|
Divisible into essentially equal halves along one or more lines or planes. |
obtrulloid |
|
solid shape |
|
Inversely trulloid. |
nutrition |
|
CHARACTER |
|
Mode of acquiring nutrients. |
tendril |
|
STRUCTURE |
|
A slender stem branch, modified leaf, or portion of a leaf that twines about a supporting structure. |
epichilium |
|
STRUCTURE |
|
The distal portion of a labellum (lip) that has distinct proximal, distal, and sometimes also central parts; in Orchidaceae. See also hypochilium, mesochilium. |
opposite 2 |
|
arrangement |
|
Having the members of each whorl inserted directly above and/or below those of the next adjacent whorl(s). See also antipetalous, antisepalous. |
