|
midvein |
= midnerve, midrib; < costa, nerve, rib, vein |
STRUCTURE |

|
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. |
|
cuculliform |
= cucullate, 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 galeiform (galeate, helmet-shaped), which overlaps conceptually. |
|
plaited 2 |
= pleated, plicate |
vernation |
|
Having alternately adaxial and abaxial lengthwise folds, resembling a closed fan. |
|
irregular 2 |
|
course |
|
Deviating asymmetrically from a straight line. |
|
bole |
= trunk; < main stem, primary stem |
STRUCTURE |
|
The relatively stout, columnar, main stem of a distinct aboveground portion of a tree. |
|
equitant |
|
arrangement |
|
Alternate, distichous, basal, and congested, each conduplicate with its lateral edges overlapping and/or overlapped by those of the immediately adjacent one(s). |
|
root 1 |
|
STRUCTURE |
|
Collectively, all those portions of a plant body that are anatomically distinct from the shoot, the component axes not differentiated into nodes and internodes, and branching endogenously. |
|
oblate |
|
plane shape |
|
Symmetrically elongate and broader than long perpendicular to the developmental or polar axis. |
|
areole 1 |
= areola |
STRUCTURE |
|
Any distinctive surficial discontinuity of generally circular outline, whether concave, flush, or convex; when protuberant, sometimes bearing trichomes or spines, as in some Cactaceae. This term is used only when such entities are deemed structurally distinctive enough to merit description in their own rights, rather than as aspects of the surface. |
|
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. |
|
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. |
|
carina 1 pl. carinae |
= keel |
STRUCTURE |
|
An elongate, median longitudinal ridge that is basically triangular in transverse section and resembles the keel of a boat; esp. in leaf blades and sheaths, glumes, lemmata, paleae, sepals, petals. |
|
median |
= central, medial |
insertion |
|
At, upon, or closely ranged about the structural or symmetrical midpoint or axis. |
|
acyclic |
= helical, spiral |
arrangement |
|
Disposed helically about and along the axis, each on a different radius than the one(s) vertically adjacent. |
|
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. |
|
column 1 |
= gynandrium, gynostemium |
STRUCTURE |
|
A central floral structure consisting of the partly to wholly fused (connate and adnate) androecium and gynoecium; esp. in Orchidaceae. |
|
papery |
= chartaceous, papyraceous |
texture |
|
Very thin, flexible, and readily torn; like paper. See also membranaceous (membranous), pergamentaceous (parchment-like). |
