|
solid shape |
|
Relatively thin with opposite broad faces, one plane and one convex. |

Having alate (winged) stems. |
|
weak |
|
texture |
|
Very pliable and unresilient. |
|
prominence |
|
CHARACTER |
|
Elevation or depression of a discrete feature relative to the surrounding surface. |
|
herb |
|
nominative |
plant |
Annual, biennial, or perennial with no woody (lignified) tissue in any part of the shoot; when persisting over more than one growing season, the parts of the shoot dying back seasonally. |
|
raphal |
|
derivation |
aril |
Produced or resulting from a modification of the raphe. |
|
rounded |
|
base |
|
Convex overall and more or less regularly curved. |
|
hypogynous |
|
insertion |
perianth, calyx, corolla, androecium |
Entirely free from the gynoecium or any floral cup, arising from a level proximal or lateral to the base of the gynoecium. See also epigynous, perigynous. |
|
akene |
|
nominative |
fruit |
See achene. |
|
homosporous |
|
reproduction |
taxon |
Producing only one type of spore, each spore giving rise to a gametophyte that bears gametangia of both sexual types. |
|
dilate(d) |
|
solid shape |
elongate structure |
Narrow at one end and broadening toward the other; esp. when essentially terete at the narrow proximal end and seemingly flattened distally, as some anther filaments. |
|
interrupted 1 |
|
architecture |
foliaceous structure |
Compound with the leaflets alternately large and small. |
|
inflated |
|
solid shape |
|
Relatively thin-walled with an essentially empty interior largely enclosed by the walls, which are convex overall and appear taut, as though from internal pressure. See also swollen (turgid, tumid), which is not clearly distinct in its application. |
|
lamella pl. lamellae |
|
STRUCTURE |
|
A thin layer of tissue that forms a plate within tissue of lesser density or between areas of empty space. |
|
evergreen |
|
habit |
plant |
Perennial and bearing some viable leaves at all times during the yearly cycle. |
|
spadix pl. spadices |
|
STRUCTURE |
|
A thick, fleshy, primary inflorescence axis bearing sessile flowers more or less sunken into its surface, the whole subtended and sometimes partially enclosed by a specialized bract, the spathe; esp. in Araceae. |
|
epipetalous |
|
insertion |
|
Upon the petals, or partially adnate thereto and apparently arising therefrom. |
|
ligule 2 |
|
STRUCTURE |
|
An adaxial, distal enation from a leaf sheath, especially in most grasses (Poaceae) and sedges (Cyperaceae); usually unitary and membranous, sometimes instead consisting of a row of ciliate processes. See also hastula. |
|
filamentous |
|
texture |
|
Composed of filiform (thread-like) strands with no intervening tissue. |
|
anthelate |
|
architecture |
inflorescence |
Comprising one or more anthelae; esp. in Juncaceae. |
|
fasciate(d) |
|
fusion |
equivalent structures |
Abnormally proliferated in size and/or number and more or less connate, the result often monstrous. |
|
mamma pl. mammae |
|
STRUCTURE |
|
A rounded-conoidal protrusion, resembling the breast of a mammal. |
