ascidium pl. ascidia |

An ascidiform (pitcher-shaped) leaf blade, sometimes operculate (lidded), usually carnivorous; esp. in Nepenthaceae, Sarraceniaceae. |
|
cucullate 2 |
= cuculliform, hood-shaped |
solid shape |
|
Convex or compressed-convex overall with a distal peak or ridge, relatively thin-walled and essentially hollow with the interior open to one side below the distal portion; resembling a hood or cowl. See also galeate (galeiform, helmet-shaped), which overlaps conceptually. |
|
centrifugal |
|
development |
|
Proceeding away from the center, thus more advanced centrally than peripherally within a given frame of reference. |
|
equatorial ridge |
|
FEATURE |
|
A circumferential ring about a megaspore in the plane of its equator, raised above the remainder of the wall surface; in some heterosporous taxa of Polypodiophyta. |
|
adventitious bud |
|
STRUCTURE |
|
A vegetative or floral bud that arises directly from a root or from some site on a shoot other than a leaf axil or stem apex. |
|
oblanciform |
= oblanceoloid |
solid shape |
|
Inversely lanciform (lancehead-shaped, lanceoloid). |
|
botuliform |
= sausage-shaped |
solid shape |
|
Arcuately cylindric with rounded ends. |
|
stiff |
= rigent, rigid |
texture |
|
Strongly resisting deformation over its length. |
|
stigma pl. stigmata, stigmas |
|
STRUCTURE |
|
An exposed, localized portion of a pistil that retains deposited pollen and stimulates its germination, the pollen tubes then growing through or along it toward the ovule(s). |
|
disc floret |
|
STRUCTURE |
|
A floret that has an actinomorphic corolla, is bisexual, functionally staminate, or functionally pistillate, and is borne in a radiate, discoid, disciform, or radiant capitulum (head) interior (distal) to any peripheral series of differing florets that may be present; in Asteraceae (Compositae). |
|
puberulent |
|
pubescence |
|
Finely pubescent in the restricted sense of that term. |
|
complanate |
= compressed; < flattened |
solid shape |
|
Flattened bilaterally, parallel to the longitudinal axis, as though pressed or squeezed from opposing sides, the external surface otherwise basically convex. This term usually implies a strong degree of flattening. See also depressed, obcompressed. |
|
tri… 1 |
= three-… |
prefix |
|
Indicating presence of or constitution by three entities of the type denoted by the term's stem; as in tricarpellate, trifurcate, trilocular. |
|
median |
= central, medial |
insertion |
|
At, upon, or closely ranged about the structural or symmetrical midpoint or axis. |
|
flagellum pl. flagella |
|
STRUCTURE |
|
A very slender whip-like structure that extends from the main body of an antherozoid and, by active undulation, propels the cell through a liquid medium. |
|
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. |
|
papery |
= chartaceous, papyraceous |
texture |
|
Very thin, flexible, and readily torn; like paper. See also membranaceous (membranous), pergamentaceous (parchment-like). |
|
infructescence 2 (not recommended) |
= coenocarp, multiple fruit, syncarp; > fig, syconium |
STRUCTURE |
|
A compound fruit derived from the connate or coherent ovaries and accessory tissue(s), if any, of two or more adjacent flowers. |
|
carnose |
= fleshy, sarcous |
texture |
|
Fairly firm and dense, juicy or at least moist, and easily cut. |
|
superposed 1 |
|
arrangement |
|
Approximate to congested, inserted directly above and below one another. |
|
entire |
|
margin |
|
Uninterrupted; not deviating significantly from its general line, thus lacking any localized convexities or concavities. |
|
reticulate 2 |
= netted |
coloration |
|
Having a pattern of interconnected fine lines of contrasting hue and/or intensity. |
|
acetabuliform |
|
solid shape |
|
Transversely circular, broader than long, widest near or at the middle, relatively thin-walled, the hollow interior open distally; like a shallow bowl with strongly incurved sides. |
|
vallecula pl. valleculae |
= colpus, fossula, furrow, groove, sulcus |
STRUCTURE |
|
A longitudinal depression that is relatively shallow and narrow; esp. in fruits of Apiaceae (Umbelliferae). |
|
architecture |
|
CHARACTER |
|
Composite structural configuration as to type, orientation, symmetry, insertion, position, fusion, presence, number, relative size, shape, texture, differentiation, and/or derivation of components and features. Overlaps conceptually with habit. |
