|
STRUCTURE |
|
The distal aperture of a syconium (fig); in Ficus (Moraceae). |
|
diplecolobal |
|
arrangement |
cotyledons |
Incumbent but with the cotyledons folded together twice or more, the folds transverse. |
|
coating |
|
CHARACTER |

nominative |
inflorescence |
A single set of pedicellate flowers in a compound umbel. |
|
paniculate |
|
architecture |
inflorescence |
Comprising one or more panicles. |
|
imperfect |
|
architecture |
flower |
Having either stamens or pistils absent or non-functional, thus unisexual. |

|
STRUCTURE |
|
A root that arises laterally from some part of a shoot, often from the lower portion of a main stem. |
|

|
base |
laminar structure |
Terete or involute and closely enclosing the supporting axis for some distance above the point of insertion. |
|
utricle |
|
nominative |
fruit |
Dry, indehiscent, one-seeded and with the pericarp thin and free from the seed; derived from a single, superior, simple ovary. |
|
infrapetiolar |
|
position |
bud |
Axillary and surrounded by the petiole base at maturity. |
|
mesocarp |
|
STRUCTURE |
|
The middle tissue layer of the pericarp of a fruit. |
|
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. |
|
callus |
|
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. |
|
entire |
|
margin |
|
Uninterrupted; not deviating significantly from its general line, thus lacking any localized convexities or concavities. |
|
annulus 1 pl. annuli |
|
STRUCTURE |
|
