Rising from beneath the water surface to a point above it. |
|
angular |
|
plane shape |
|
Having sides that meet at acute or obtuse angles. |
|
germination 1 |
|
CHARACTER |
|
The process wherein a dormant embryo resumes active metabolism and growth, the primary root and shoot emerging from the seed coat, the young sporophyte thereupon entering the seedling stage. |
|
monochasiate |
|
architecture |
inflorescence |
Comprising one or more simple or compound monochasia. See also cincinnate, cymose, cymulose, dichasiate, helicoid-cymose, scorpioid-cymose. |
|
reclinate |

vernation |
|
Each with its blade oriented downward and parallel to the proximal portion of its distally recurved petiole. |
|
suprabracteal |
|
insertion |
|
Upon the axes, each directly above (distal to) and very near a point of bract insertion. |
|
knee-rooted |
|
architecture |
plant |
Having knee roots. |
|
phanerocotyloid |
|
germination |
seed |
Having the cotyledon(s) emerging from the seed coat. |
|
viscidium pl. viscidia |
|
STRUCTURE |
|
A small, viscid, glandular body of rostellar origin that becomes connected with a pollinium caudicle, either directly or through an intervening stipe, by which the pollinium attaches to a pollinating insect; in Orchidaceae. |
|
epiphytic |
|
habit |
plant |
Physically supported in its entirety by another plant through all or the major part of its life. |
|
naked 2 |

architecture |
bud |
Lacking enclosing protective scales, the outermost embryonic components exposed and not differing significantly from those within. See also perulate. |
|
rhipidium pl. rhipidia |
|
nominative |
inflorescence |
A cyme with the branches alternate and disposed in two opposite ranks along the main axis, the whole fan-like. |
|
synstemonous |

architecture |
flower, androecium |
Having two or more stamens, some or all of them connate. |
|
placenta pl. placentae, placentas |
|
STRUCTURE |
|
An ovule-bearing zone of the tissue surface bordering an ovary locule; of merely topographic, not histological, significance; may be a part of the ovary wall proper or an extension from it, or a part of the central axis of the ovary or an extension from it. |
|
wiry |
|
architecture |
axis |
Relatively very narrow and elongate, tough, and resiliently flexible. |
|
explosive |
|
dehiscence |
|
Opening abruptly with almost instantaneous aperture formation and release of accumulated structural tensions, the contents thus forcibly expelled. |
