An outgrowth from the seed coat (testa) around or near the hilum and micropyle, or from the raphe. |
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. |

arrangement |
|
Disposed in the number of verticils (cycles, series, whorls) indicated by the prefix; as in five-whorled, 3-whorled. |
vesicle |
|
STRUCTURE |
|
A small bladder-like part consisting of an enclosing wall or covering and an empty or fluid-filled interior, sometimes turgid; esp. in citrus fruits (hesperidia). |
gongyloid |
= gongylodate, knob-shaped, knot-shaped, nodiform |
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. |
cupulate |
= calyciform, cup-shaped |
solid shape |
|
Truncate-globose with the distal margin more or less entire; like the bowl of a cup. |
obovate |
|
plane shape |
|
Inversely ovate (egg-shaped). |
hirsute |
|
pubescence |
|
Bearing coarse, rough, elongate, more or less erect, capillate trichomes. See also hirtellous. |
stipel |
|
STRUCTURE |
|
A stipular analogue subtending a leaflet. |
discolor(ous) |
> bicolor(ous) |
coloration |
|
Having surfaces of different colors; esp. leaves with differently colored adaxial and abaxial surfaces. |
balding |
= glabrescent |
pubescence |
|
Becoming bald (glabrous, psilate) with age. |
bristle 1 |
= arista, awn, seta |
STRUCTURE |
|
A slender, more or less straight and stiff, fine-pointed, terminal or subterminal appendage or prolongation, sometimes a continuation of the bearing structure's central primary vein, as on a glume, lemma, or palea in Poaceae (Gramineae). |
megaspore |
= macrospore (not recommended) |
STRUCTURE |
|
A female spore; a spore of the larger of two types produced by the sporophytes of a heterosporous taxon; produced in a megasporangium; giving rise upon germination to a megagametophyte. |
gemma pl. gemmae |
|
STRUCTURE |
|
A vegetative propagule by which a gametophyte reproduces asexually; produced by a process analogous to budding, from a more or less cupulate specialized area (gemmae cup) on the surface of the plant body (thallus); in Psilotophyta, Lycopodiophyta, Equisetophyta, Polypodiophyta. |
intercostal |
|
insertion |
|
Between the costae. |
suprabasal |
|
position |
|
Just above the base of the structure in point. |
epicalyx pl. epicalyces |
= calyculus |
STRUCTURE |
|
A whorl of bracts immediately subtending (beneath or outside) a calyx. |
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. |
