antrorse |
|
orientation |
|
Directed forward or upward, toward the distal end of the context of reference, parallel or at an acute angle to the bearing structure. |
determinate |
|
development |
|
Having the terminal (central, apical, or distal) portion differentiating first and the lateral (peripheral, basal, or proximal) portions later, development thus proceeding sequentially downward or outward, growth of the whole thereby organizationally limited. |
receptacle 2 |
= torus |
STRUCTURE |
|
The short, expanded, compound axial structure surmounting a peduncle and basal to two or more flowers, or to the florets of a capitulum (head) in Asteraceae (Compositae), where it may bear paleae (receptacular bracts), scales, bristles, trichomes, or subulate enations, and may be smooth or variously pitted (alveolate, foveolate). |
extravaginal |
|
insertion |
|
Distal to or outside the leaf sheath. |
muriculate |
|
relief |
|
Finely muricate. |
waxen 1 |
= ceraceous, cereous, waxen; > caesious, glaucescent, glaucous, pruinose |
coating |
|
Covered with wax or a wax-like substance. |
bifacial |
|
architecture |
|
Having two opposite broad surfaces that differ distinctly in appearance. |
gynostemium pl. gynostemia |
= column, gynandrium |
STRUCTURE |
|
A central floral structure consisting of the partly to wholly fused (connate and adnate) androecium and gynoecium; esp. in Orchidaceae. |
abaxial |
= dorsal (not recommended) |
position |
|
On or pertaining to the side or portion of a lateral structure that faces (or would face) away from the bearing axis when (or if) the axis of the lateral structure is (or were) oriented in the same general direction as the bearing axis. |
spore case |
= sporangium |
STRUCTURE |
|
A spore-producing organ; basically capsular, often supported by a slender stalk (sporangiophore), often lidded (operculate). In Bryophyta and Polypodiophyta, a distinct portion of the sporangial wall effects regular dehiscence at maturity. Spore cases or their equivalents are also present, but of little or no descriptive significance, in seed plants. |
coriaceous |
= leathery |
texture |
|
Moderately thick, tough, and very pliable. |
lobate |
? cleft, dissected, divided, lobed, parted, partite, segmented |
plane shape |
|
Having one or more component sectors or peripheral protrusions that is/are delimited by concavities in the surface or margin and that is/are not proximally distinct from the remainder of the whole. The meanings of this term and its approximate synonyms sometimes have been supposed to differ according to the depth of the delimiting concavities relative to the midline or midpoint of the overall structure, and/or to the shape or proportions of the protusions or sectors; however, there has been little consistency in the applications of the various terms according to such distinctions, which are ones only of degree and are necessarily arbitrary in any case. In general usage, these terms differ only indistinctly and connotatively: cleft, lobed (or lobate), parted (or partite) and segmented tend to connote fewer protrusions or sectors; lobate usually connotes as well a generally rounded shape; dissected tends to connote more numerous sectors that are elongate and angular. See also cut (incised, lacerate, torn), laciniate (slashed). |
tuberculose 2 |
= tubercular |
solid shape |
|
Comprising small knot-like segments. |
oleaginous 2 |
= greasy, oily, unctuous |
texture |
|
Liquid or deformably solid, cohesive, and slippery to the touch. |
canalicular |
|
position |
|
Upon or otherwise directly associated with the channel of a petiole or petiolule. |
hyaline |
= pellucid; > translucent, transparent |
coloration |
|
Transmitting light uniformly. |
strigulose |
= strigillose |
pubescence |
|
Finely strigose. |
androphore |
>< stalk |
STRUCTURE |
|
A stalk or tube that rises above the level of perianth insertion and bears the distinct portions of the androecium from its summit; as in Malvaceae, where the androphore is a tube formed by connation of the filaments. |
rachilla 1 var. rhachilla |
|
STRUCTURE |
|
A second- or higher-order axis of a compound leaf blade, bearing higher-order rachillae, leaflets, pinnules and/or tendrils. |
mitriform |
= mitre-shaped |
solid shape |
|
Broadest and transversely round to oval proximally, tapering bilaterally above the middle to a central peak; like a peaked hat or cap. |
vernation |
|
CHARACTER |
|
Disposition of leaves in the bud. |
glossy |
= laevigate, lustrous, polished, shining, shiny |
reflectance |
|
Uniformly reflecting a high proportion of incident light at all angles. |
spheroid(al) |
= globose, globular, orbicular, rotund, spheric(al) |
solid shape |
|
Uniformly convex, circular in any median section and in outline when viewed from any angle; like a sphere or globe. |
concolor(ous) |
|
coloration |
|
Uniform in hue and intensity of color; esp. leaves with identically colored adaxial and abaxial surfaces. |
plane shape |
|
CHARACTER |
|
Overall two-dimensional form or aspect(s) thereof. Overlaps conceptually with architecture, arrangement, habit, insertion, orientation, and position. |
