|
STRUCTURE |
|
The middle tissue layer of the pericarp of a fruit. |
|

FEATURE |
|
A small, relatively hard covering, outgrowth, or swelling of tissue; esp. in axes of grass (Poaceae) inflorescences just distal to points of eventual disarticulation. |
|
iridescent |
|
coloration |
|
Reflecting a pattern colors from throughout the visible spectrum, the pattern changing with the angle of view. |
|
perigynium 1 pl. perigynia |
|
STRUCTURE |
|
Two whorls of bracts, scales or setae immediately subtending the ovary, sometimes cupulate (cup-shaped) or ampulliform (flask-shaped, lageniform) and investing the fruit (achene); in Cyperaceae. |
|
entire |
|
margin |
|
Uninterrupted; not deviating significantly from its general line, thus lacking any localized convexities or concavities. |
|
annulus 1 pl. annuli |
|
STRUCTURE |
|
A small ring-like protrusion from the strobilar stalk near its base and below the lowermost sporangiophores, sometimes bearing small sporangia; esp. in Equisetum. |
|
mottled |
|
coloration |
|
Having one or more indistinctly delineated, irregularly shaped, areas of varying size and contrasting hue and/or intensity. |
|
costule |
|
STRUCTURE |
|
A longitudinal primary vein in a diminutive laminar structure, such as the blade of a leaflet, pinna or pinnule; a diminutive costa (rib). |
|
…pinnate |
|
architecture |
foliaceous structure |
Compound with the number of orders of leaflets indicated by the prefix, each order pinnate; as in bipinnate, tripinnate. |
|
spiculate |
|
relief |
|
Having small, fine, stiff, acute protrusions that resemble little spikes. See also scabridulous (scabrellate, scabrellous, which is not clearly distinct in its application. |
|
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). |
|
apostemonous |
|
architecture |
flower, androecium |
Having two or more distinct stamens; having the stamens unfused. |
|
grumous |
|
solid shape |
|
Having an external aspect like a cluster of grains, basically convex overall. |
|
laticiferous |
|
exudation |
|
Producing and exuding latex. |
|
obconic(al) |
|
solid shape |
|
Transversely round, essentially triangular in median longitudinal section, and broadest distally; inversely conic(al) (cone-shaped). |
|
rounded |
|
base |
|
Convex overall and more or less regularly curved. |
|
pore |
|
FEATURE |
|
A small aperture or opening in a wall or covering that allows transport between interior and exterior. |
|
staminal |
|
position |
|
Upon or otherwise directly associated with the stamens. |
|
axillary |
|
insertion |
|
Within the axil; nodal and at or very close to the vertex of the distal angle between a lateral structure, especially a leaf, and the axis that bears it. |
|
ocrea pl. ocreae var. ochrea |
|
STRUCTURE |
|
A tubular sheath that encircles a stem at a node, subtending a petiole; thought to have arisen evolutionarily by lateral fusion of two stipules; in Polygonaceae. |
|
determinate |
|
development |
|
Having the terminal (central, apical, or distal) portion differentiating first and the lateral (peripheral, basal, or proximal) portions later, development thus proceeding sequentially downward or outward, growth of the whole thereby organizationally limited. |
|
horizontal |
|
orientation |
|
Parallel to the horizon, perpendicular to the force of gravity. |
|
ovary |
|
STRUCTURE |
|
The proximal portion of a pistil (either simple or compound) within which the ovules are borne; usually of somewhat greater diameter and/or volume than the remainder of the pistil. |
|
diplotegium pl. diplotegia |
|
nominative |
fruit |
A pyxis with accessory tissue adnate to the pericarp; derived from an inferior ovary. |
