|
plane shape |
|
Having sides that meet at acute or obtuse angles. |
connate-perfoliate |
|
architecture |
opposite laminar structures |
Having the bases in each pair fused and together encircling the bearing axis. See also amplexicaulous, perfoliate. |
syngenesious |
|
fusion |
flower, androecium |
Having the anthers connate or coherent and forming a ring. |
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. |
sterile |
|
reproduction |
plant, reproductive structure |
Not producing functional spores, gametes, pollen, ovules, seeds, or other propagules. |
coronal |
|
insertion |
|
Upon or otherwise directly associated with the corona. |
odorless |
|
odor |
|
Lacking a distinct odor. |
tubercle |
|
FEATURE |
|
A small, rounded, knot-like swelling or wart-like protrusion. |
flush |
|
prominence |
|
Even with the surrounding surface, neither higher nor lower than its general level. |
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. |
vascular bundle |
|
STRUCTURE |
|
A discrete strand of conducting tissues (xylem, phloem) and associated cells (e.g., cambium) within a stem or other axial structure. |
pachycaulous |
|
architecture |
plant |
Having thick, more or less succulent stems. |
obconic(al) |
|
solid shape |
|
Transversely round, essentially triangular in median longitudinal section, and broadest distally; inversely conic(al) (cone-shaped). |
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. |
periclinal |
|
orientation |
|
Parallel to some given plane of reference; applied especially to the plane of cell division when it is oriented parallel to the generalized plane of the structural surface. |
involucrate 1 |
|
architecture |
inflorescence |
Subtended by an involucre. |
cymose |
|
architecture |
inflorescence |
Comprising one or more simple or compound cymes. See also cincinnate, cymulose, dichasiate, helicoid-cymose, monochasiate, rhipidiate, scorpioid-cymose. |
staminodial |
|
position |
|
Upon or otherwise directly associated with the staminodes. |
caespitose |
|
habit |
|
See cespitose. |
axil |
|
FEATURE |
|
The space bounded by and near the vertex of the distal angle between a lateral structure, especially a leaf, and the axis that bears it. |
prophyllar |
|
insertion |
|
Upon or otherwise directly associated with the prophylls (bracteoles, bractlets). |
