oblong 2 |
|
solid shape |
|
Compressed-ellipsoid, the sides approximately parallel from near one end to near the other. See also ellipsoid(al). |
hippocrepiform |
= horseshoe-shaped |
solid shape |
|
Relatively slender and strongly compressed, the whole strongly curved over its length in a plane perpendicular to the direction of compression and forming an incomplete circle, the ends somewhat straighter than the rest and parallel or nearly so; like a horseshoe. |
stipe 2 (broad sense, not recommended) |

STRUCTURE |
|
A stalk of or supporting a frond, inflorescence, or gynoecium. |
pulverulent |
= granuliferous, powdery |
coating |
|
Covered with a more or less even deposit of fine, dry particles. See also lentiginous (dusty, lentiginose), which is not clearly distinct in its application. |
megasporangium pl. megasporangia |
= macrosporangium (not recommended) |
STRUCTURE |
|
A sporangium that produces megaspores. |
seed leaf |
= cotyledon |
STRUCTURE |
|
Any of the one or more primary foliar structures of an embryonic seed plant, proximal to all succeeding leaf primordia; sometimes serving as a storage organ for food reserves in the seed, as in peas and beans. |
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. |
papillose |
= papillate |
relief |
|
Having small, conoidal protrusions overall; appearing pimply. |
acicular 2 |
= acerose, needle-shaped |
solid shape |
|
Rounded in cross-section and very slenderly elongate, broadest near the middle, and gradually attenuate to an acute apex and a slightly blunter base; like a needle. |
suprabasal |
|
insertion |
|
Just above the base of the structure in point. |
calyptriform |
|
solid shape |
|
Hollow, roughly circular in cross-section, broader and open distally, and tapering to a closed apex, like a candle snuffer or elongate hood. |
epibracteal |
|
position |
|
Upon the bracts, or partially adnate thereto and apparently arising therefrom. |
revolute 2 |
|
vernation |
|
Each rolled abaxially inward from the lateral margins. |
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. |
rhachilla |
|
STRUCTURE |
|
See rachilla. |
nodiform |
= gongylodate, gongyloid, knob-shaped, knot-shaped |
solid shape |
|
Approximately globose, the surface convoluted or not, like a knob or knot; usually applied only to structures or components that are relatively small. |
xylem |
= wood |
STRUCTURE |
|
The water-conducting and usually main supporting tissue of a plant or portion thereof, characterized by the presence of tracheary elements (tracheids and sometimes vessel elements); the lignified tissue of a plant or component structure, composed almost entirely of secondary tissue, i.e., that derived by secondary or lateral growth from a cambium in structures a season or more old. See also sapwood, heartwood. |
heartwood |
|
STRUCTURE |
|
The senescent inner or central portion of the wood (xylem) of an older stem or root, its cells no longer living, in which conduction has ceased and primary reserve materials are no longer stored; often containing terminal metabolic products; usually darker in color than the living, conducting sapwood that encircles it. |
pistil |
> carpel |
STRUCTURE |
|
Any simple or compound, discrete or histologically distinct, female (ovule-producing) floral structure, or any putatively homologous sterile structure; comprising an ovary and one or more stigmas borne either directly upon the ovary or upon one or more intervening styles. See also gynoecium. |
leaf 1 pl. leaves |
= frond, macrophyll (not recommended), megaphyll; > frond, needle |
STRUCTURE |
|
A principal, vegetative shoot organ borne laterally from a stem node; its vascular tissues, if any, continuous with those of the stem; undergoing no significant secondary growth; usually more or less bilaterally symmetrical; comprising a distal, usually laminar blade and/or a proximal stalk (petiole) or sheath; usually a primary site of photosynthesis. |
tongue-shaped |
= lingulate |
solid shape |
|
Broadly elongate and compressed, one broad face more or less plane and the other convex, the edges rounded between them; like a tongue. |
circinate 1 |
|
solid shape |
|
Terete and rolled downward from the apex in a tight coil. |
…fid |
? …cleft, …lobate, …lobed, …parted, …partite, …segmented |
solid shape |
|
Having the number of lobes, divisions or segments indicated by the prefix; as in bifid, quadrifid. |
scalloplet |
= crenule |
FEATURE |
|
A diminutive scallop (crena). See also sawtooth, sawtoothlet, tooth (dens), toothlet. |
balding |
= glabrescent |
pubescence |
|
Becoming bald (glabrous, psilate) with age. |
