architecture |
|
Having one or more elongate, relatively thin protrusions or appendages that resemble wings. |
|
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 |

Approximately globose, the surface convoluted or not, like a knob or knot; usually applied only to structures or components that are relatively small. |
|
bell-shaped |
= campanulate |
solid shape |
|
Circular in cross-section, inflated proximally, thence broadening gradually to a flared distal portion. |
|
calyx pl. calyces |
|
STRUCTURE |
|
Collectively, the sepals of a flower, whether distinct or connate; the outer or proximal envelope of a differentiated perianth, whether the other envelope (corolla) is also actually present or is deemed to be secondarily absent due to evolutionary reduction. |
|
coma pl. comae, comas |
< tuft |
STRUCTURE |
|
A prominent single tuft of relatively long and slender, flexible, capillate trichomes; esp. from a seed, as in Asclepias (Asclepiadaceae). |
|
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. |
|
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. |
|
acrocaulous |
|
position |
|
At or very near the stem tip. |
|
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. |
|
banner |
= standard, vexillum |
STRUCTURE |
|
The relatively large, erect adaxial (upper) petal in a papilionaceous corolla. |
|
crested |
= cristate |
apex |
|
Having a laterally elongate, relatively thin, irregular or notched protrusion. |
|
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. |
|
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. |
