dehiscence |
|
Parallel to the central axis. |
|
horizontal |
|
orientation |
|
Parallel to the horizon, perpendicular to the force of gravity. |
|
longitudinal 2 |
|
orientation |
|
Parallel to the long axis of the context of reference. |
|
coalescent |
|
fusion |
equivalent and/or dissimilar structures |
Partially and irregularly coherent and/or adherent. |
|
symbiotic |
|
nutrition |
plant |
Partially dependent for essential nourishment upon other living organisms that derive some reciprocal benefit from the relationship. |
|
hemiepiphytic |
|
habit |
plant |
Partially epiphytic; rooted in the ground but with stems growing upon and supported mainly by other plants. |
|
hemiparasitic |
|
nutrition |
plant |
Partially parasitic; facultatively heterotrophic to a limited degree and capable of obtaining a portion of its essential nourishment directly from other living organisms, to which no reciprocal benefit accrues. |
|
umbel |
|
nominative |
inflorescence |
Pedunculate, determinate or indeterminate, simple or compound and apparently polychotomous, with one or more pedicellate flowers terminating each ultimate axis, the pedicels of each such floral set and the branches (rays) arising from each axial subdivision diverging from each other like the ribs of an umbrella, the whole plane, convex or concave distally. |
|
evergreen |
|
habit |
plant |
Perennial and bearing some viable leaves at all times during the yearly cycle. |
|
deciduous 2 |
|
habit |
plant |
Perennial and having all leaves separating and falling away during a particular portion of the yearly cycle, especially the autumn or the dry season, between growing seasons. Semantically, this term is properly applied only to the entity that falls, not to the structure that it separates and falls from; in traditional usage, though, the term has been applied to trees and other perennial plants that shed all their leaves at some time during the yearly cycle. |
|
pliestesial |
|
duration |
plant |
Perennial and monocarpic, living several to many years before reproducing sexually, dying promptly thereafter. |
|
liana |
< vine |
nominative |
plant |
Perennial with elongate ligneous stems that are flexible at least initially and that climb upon trees and shrubs. |
|
vine |
> liana |
nominative |
plant |
Perennial, with elongate, herbaceous or ligneous stems that are flexible at least initially and that clamber, climb or trail. |
|
tree |
|
nominative |
plant |
Perennial, woody, more or less erect, relatively tall, with one or more distinct aboveground portions each with a single, relatively stout, columnar, main stem (trunk or bole) that bears branches. See also bush, frutex, shrub, subshrub, suffrutex, undershrub, woody clump. |
|
shrub |
= frutex; > bush |
nominative |
plant |
Perennial, woody, relatively short, with a single main stem that is not distinctly columnar and branches from or above ground level, the branches often crowded. See also subshrub (suffrutex, undershrub), tree, woody clump. |
|
frutex pl. frutices |
= shrub; > bush |
nominative |
plant |
Perennial, woody, relatively short, with a single main stem that is not distinctly columnar and branches from or above ground level, the branches often crowded. See also suffrutex (subshrub, undershrub), tree, woody clump. |
|
pericolporate |
|
architecture |
pollen grain |
Pericolpate, each groove containing a pore. |
|
percurrent 2 |
|
architecture |
tertiary laminar veins |
Perpendicular to and interconnecting adjacent parallel secondary veins, the secondary and tertiary veins together forming a scalariform pattern. |
|
anticlinal |
|
orientation |
|
Perpendicular to some given plane of reference; applied especially to the plane of cell division when it is oriented at right angles to the generalized plane of the structural surface. |
|
erect |
|
orientation |
|
Perpendicular to the horizon or to the general plane of a bearing structure. |
|
transverse 2 |
|
orientation |
|
Perpendicular to the long axis of the context of reference. |
|
marcescent |
|
duration |
structure |
Persistent in a distinctly withered condition. |
|
perennate |
|
duration |
structure |
Persisting in a functional state through the entire growing season. |
|
peltate |
|
architecture |
foliaceous structure |
Petiolate with the petiole attached to the abaxial face of the blade at some point within the margin and otherwise free from the blade. |
|
fusion |
|
CHARACTER |
|
Physical connection of equivalent or dissimilar structural entities (as recognized on evolutionary, morphological, anatomical, ontogenetic, and/or topological grounds). Terms that denote the interconnection of equivalent structures are predicated on a single collective subject and suffice in themselves to describe the condition; e.g., "sepals connate." However, those that denote the connection of dissimilar structures require explicit notation of each type of structure involved, in either a compound-subject construction or else a single-subject/object-of-preposition construction; e.g., "stamens and corolla adnate" or "stamens adnate to corolla." Qualifying detail is sometimes appropriate; e.g., "filaments connate basally," "filaments adnate to the petals over their lower halves." |
