oblique 1 |
|
apex |
|
Asymmetric about its longitudinal axis. |
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. |
secondary vein |
< lateral vein |
STRUCTURE |
|
A strand belonging to the second order of vasculature in a leaf or other basically laminar structure, except when that is the ultimate order (consisting of veinlets); branching directly from a primary vein or, with undiminished diameter, from another strand of the second order. See also costa, primary vein, rib, tertiary vein, veinlet. |
laminar 2 |
|
solid shape |
|
Relatively very thin with parallel opposite broad faces, the whole plane or variously curved. Structures to which this term, along with any other three-dimensional ones, is applicable are often also described as though only two-dimensional, using terms that are implicitly understood to refer only to the outline of the broad faces. |
winged 1 |
= alate |
architecture |
|
Having one or more elongate, relatively thin protrusions or appendages that resemble wings. |
bald |
= glabrous, psilate |
pubescence |
|
Lacking trichomes. |
galeate |
= galeiform, helmet-shaped |
solid shape |
|
Convex overall with a more or less smoothly curved apex, relatively thin-walled and essentially hollow with the interior open to one side below the distal portion; resembling a helmet. See also cucullate (cuculliform, hood-shaped), which overlaps conceptually. |
solid shape |
|
CHARACTER |
|
Overall three-dimensional form or aspect(s) thereof. Overlaps conceptually with architecture, arrangement, habit, insertion, orientation, position, relief, and texture (as to thickness). |
prickle |
|
STRUCTURE |
|
Any unvascularized spine-like enation originating in the epidermis, cortex, or mesophyll of any shoot part. See also spine, thorn. |
operculate |
= lidded |
architecture |
|
Having an operculum (lid). |
depressed |
< flattened |
solid shape |
|
Flattened distally, perpendicular to the longitudinal axis, as though pressed from the top, the external surface otherwise basically convex. Often used in combination with some other term that describes the overall shape exclusive of ("before") flattening, e.g., depressed-globose. See also compressed (complanate), obcompressed. |
connective |
|
STRUCTURE |
|
The tissue between and joining the laterally opposed thecae of an anther, connecting them with the distal end of the staminal filament when the latter is present. |
toothlet |
|
STRUCTURE |
|
A diminutive tooth (dens). See also sawtooth, sawtoothlet, scallop (crena), scalloplet (crenule). |
pinnule |
< leaflet |
STRUCTURE |
|
A second- or higher-order division or leaflet of a pinnate frond; a division of a pinna; in Polypodiophyta. |
androgynophore |
< stalk |
STRUCTURE |
|
A stalk that rises above the level of perianth insertion and bears the free portions of both androecium and gynoecium from its summit; as in Passifloraceae. |
subsidiary 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. |
scalariform |
= ladder-like |
arrangement |
|
Disposed in vertical sequence with long axes horizontal and parallel. |
kidney-shaped 2 |
= reniform |
solid shape |
|
Thickly elongate and arcuate, circular or compressed-circular in transverse section, each end bluntly rounded; like the generalized shape of a human kidney. |
rugose |
= corrugate, wrinkled |
relief |
|
Having irregular, narrow ridges or creases, the intervening areas flat to shallowly concave or convex, appearing overall as though crumpled and then spread out. See also rugulose. |
foveate |
= pitted |
relief |
|
Having numerous, small, rounded depressions. See also foveolate (fine-pitted, scrobiculate). |
insertion |
|
CHARACTER |
|
Mode or locus of attachment of a structure to some dissimilar bearing structure. The lexicons relating to insertion and position overlap to a great degree, since these two morphological concepts are often inseparable in practice. Also overlaps conceptually with arrangement, habit, orientation, and shape. |
…morphic |
|
architecture |
|
Existing within the taxon in the number of distinct structural states indicated by the prefix, the states segregated in different sets of plants or not; as in monomorphic, polymorphic, trimorphic. |
pluri… |
= many-…, multi…, poly… |
prefix |
|
Indicating presence of or constitution by a relatively large number of entities of the type denoted by the term's stem; as in plurilocular, pluriseriate. See also oligo… (few-…). |
mamillate |
|
relief |
|
Bearing mamillae. |
cymbiform |
= boat-shaped, navicular |
solid shape |
|
Like the generalized form of a boat hull, the walls relatively thin to moderately thick, the interior essentially empty and open along one side. |
