|
biconvex 1 |
= lens-shaped, lenticular |
plane shape |
|
Elongate, narrow, broadest at the middle, attenuate to acute ends, the sides convex; like the outline of a double-convex lens viewed from its edge. |
|
hyphodromous |
= one-veined, single-veined |
venation |
|
Having one median, primary vein and no other venation externally evident. |
|
style |
|
STRUCTURE |
|
A narrow, usually elongate, ontogenetically distal portion of a simple or compound pistil, overtopping the ovary and bearing one or more stigmas; arising from the summit of the ovary, but sometimes apparently from its base at maturity to ontogenetic displacement from its primordial distal position. In a compound pistil the various simple (carpellary) components of the style(s) may not be connate over their entire lengths; the pistil is then regarded as having a branched style or styles. |
|
composite |
= compound |
architecture |
|
Unitary as a whole but comprising two or more equivalent substructural entities, these topologically distinct (e.g., leaflets in a compound leaf) or not (e.g., carpels in a compound pistil). |

|
pleated 2 |
= plaited, plicate |
vernation |
|
Having alternately adaxial and abaxial lengthwise folds, resembling a closed fan. |
|
flexible |
= pliable, pliant, supple |
texture |
|
Able to bend over its length and/or breadth without structural disruption. |
|
lid |
= operculum |
STRUCTURE |
|
A distal, cover-like portion of a structure whose main body is otherwise closed, transversely discontinuous with the main body around most of the circumference, or becoming partially or wholly separate by transverse dehiscence; as of a pitcher (ascidium), pollen grain, pyxis, or spore case (sporangium). |
|
rostellate |
= small-beaked |
apex |
|
Diminutively rostrate (beaked). |
|
obovoid |
|
solid shape |
|
Inversely ovoid (egg-shaped). |
|
hirtellous |
|
pubescence |
|
Finely hirsute. |
|
cobwebby |
= arachnoid |
pubescence |
|
Of fairly sparse, fine, white, loosely tangled, capillate trichomes. |
|
beaklet 2 |
= rostellum |
STRUCTURE |
|
A sterile excrescent stigma lobe protruding between the anther and the functional stigma lobes of a column; sometimes forming one or more viscidia at pollinium maturity; esp. in Orchidaceae. |
|
pulvinate 2 |
= cushion-shaped, mound-shaped, pulviniform |
solid shape |
|
Essentially round in transverse section, much broader than long or high, with a convex distal face that intersects either a more or less plane proximal face or, when the structure is sessile, its bearing surface. |
|
gland |
> nectary |
STRUCTURE |
|
An anatomically distinct multicellular structure that produces and exudes a particular substance, or resembles those that do. |
|
megasporocarp |
= macrosporocarp (not recommended) |
STRUCTURE |
|
A sporocarp that bears only megasporangia. |
|
seedling |
|
PLANT |
|
A plant in the first stages of its growth following emergence from the seed. |
|
acinaciform |
= scimitar-shaped |
solid shape |
|
Thin and moderately arcuate with two opposite, plane, broad faces, the degree of curvature increasing distally, thinnest at the convex edge, thicker toward the concave; like a scimitar blade. |
|
pappus pl. pappi |
|
STRUCTURE |
|
A set of one or more awns (aristae, bristles, setae) or scales at the summit of an inferior ovary just beneath or outside the free portion of the corolla; persisting in the fruit (cypsela) and often aiding wind or animal dispersal; in Asteraceae (Compositae). Considered by some to be an evolutionarily modified upper calyx portion, the lower portion having been incorporated into the floral tube casing adnate to the ovary wall; considered by others to be an outgrowth from the ovary wall. |
|
calyx tube |
|
STRUCTURE |
|
A relatively narrow, fully connate portion of a synsepalous (gamosepalous) calyx proximal to a broader portion (limb) that comprises the distinct or connate distal portions of the sepals. |
|
intercostal |
|
position |
|
Between the costae. |
|
suprabracteal |
|
insertion |
|
Upon the axes, each directly above (distal to) and very near a point of bract insertion. |
|
rhachis |
|
STRUCTURE |
|
See rachis. |
|
corticate |
= hard-coated |
texture |
|
Having a hard exterior layer and a distinct, softer interior. |
|
nodose |
= knobby, knotty |
solid shape |
|
Having nodiform (gongylodate, gongyloid, knob-shaped, knot-shaped) protrusions. See also nodulose. |
