|
peripheral |
|
insertion |
|
Upon or otherwise directly associated with the outer surfaces or regions of a three-dimensional structure. Although use of this term in two-dimensional contexts is technically correct, traditionally the term marginal is preferred in such cases. |
|
polygamous |
|
reproduction |
taxon |
Having both bisexual and unisexual flowers, borne on the same or on different plants. |
|
valvate 2 |
|
arrangement |
planate structures |
Not overlapping, adjacent members laterally contiguous at their margins. |
|
fragrant |
|
odor |
|
Sweet or otherwise pleasant. |
|
plantlet |
|
STRUCTURE |
|
A juvenile, complete plant produced asexually by budding, as from the leaf margin in some Kalanchoë (Crassulaceae); this term is usually applied only while such vegetatively produced offspring remain attached to the plant of origin. |
|
xylary |
|
position |
|
Within or otherwise directly associated with the wood. |
|
floricane |
|
STRUCTURE |
|
A biennial or perennial stem after it has begun flowering, when that does not occur until at least its second season of growth; applied especially to the stems of brambles (Rubus spp.). |
|
reproduction |
|
CHARACTER |
|
Type, morphology, disposition, function and/or dissemination of reproductive structures. |
|
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. |
|
bifacial |
|
architecture |
|
Having two opposite broad surfaces that differ distinctly in appearance. |
|
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. |
|
calyx tube |
|
STRUCTURE |
|
A relatively narrow, fully connate portion of a synsepalous (gamosepalous) calyx proximal to a broader portion (limb) that comprises the distinct or connate distal portions of the sepals. |
|
homosporous |
|
reproduction |
taxon |
Producing only one type of spore, each spore giving rise to a gametophyte that bears gametangia of both sexual types. |
|
anisopetalous |
|
architecture |
flower, perianth, corolla |
Having petals unequal in size and/or shape. |
|
interrupted 1 |
|
architecture |
foliaceous structure |
Compound with the leaflets alternately large and small. |
|
centrifugal |
|
development |
|
Proceeding away from the center, thus more advanced centrally than peripherally within a given frame of reference. |
|
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. |
|
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. |
|
circinate 2 |
|
vernation |
|
Having each leaf (frond) rolled adaxially from the sides and downward from the apex, forming a tight, flat coil; esp. in Polypodiophyta. |
|
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. |
