|
carina 1 pl. carinae |
= keel |
STRUCTURE |
|
An elongate, median longitudinal ridge that is basically triangular in transverse section and resembles the keel of a boat; esp. in leaf blades and sheaths, glumes, lemmata, paleae, sepals, petals. |
|
pinna pl. pinnae |

STRUCTURE |
|
One of the first-order divisions or leaflets of a pinnate frond; in Polypodiophyta. See also pinnule. |
|
compact |
= congested, crowded |
architecture |
|
Having equivalent constituent parts disposed very near to one another. |
|
pulviniform |
= cushion-shaped, mound-shaped, pulvinate |
solid shape |
|
Essentially round in transverse section, much broader than long or high, with a convex distal face that intersects either a more or less plane proximal face or, when the structure is sessile, its bearing surface. |
|
cyclic |
= seriate, verticillate, whorled |
arrangement |
|
Disposed along the axis in groups of three or more, the members of each group (cycle, series, verticil, whorl) inserted around the axis at the same level. |
|
ear-shaped |
= auriform |
solid shape |
|
Resembling a mammalian outer ear. |
|
setulose |
= hispidulous, small-bristly |
pubescence |
|
Finely setose (hispid). |
|
fertile frond |
< spore leaf, sporophyll |
STRUCTURE |
|
A frond that bears sporangia; in Polypodiophyta. See also sterile frond (trophophyll). |
|
germination 2 |
|
CHARACTER |
|
The process wherein the contents of a spore begin active growth, exiting the confines of the spore wall via a pore or crack and giving rise to a gametophyte. |
|
suprabasal |
|
position |
|
Just above the base of the structure in point. |
|
trochlear |
= pulley-wheel-shaped |
solid shape |
|
Discoid (disciform) but with the circumferential surface concave between faces. |
|
kneecap-shaped |
= patelliform |
solid shape |
|
Thickly meniscoid, like a human kneecap. |
|
viscid 2 |
< glutinous |
texture |
|
Sticky. |
|
ampulla pl. ampullae |
= bladder |
STRUCTURE |
|
A small, membranous, hollow, flask-shaped, insectivorous structure borne on a submerged leaf; esp. in Lentibulariaceae. |
|
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. |
|
ocellate |
= eyespotted |
coloration |
|
Having a more or less circular area that differes in hue and/or intensity from the remainder of the structure; esp. a corolla with such an area at its center. |
|
calyciform |
= cup-shaped, cupulate |
solid shape |
|
Truncate-globose with the distal margin more or less entire; like the bowl of a cup. |
|
clustered 1 |
|
arrangement |
|
Disposed in one or more aggregates, the members of each inserted close together, thence widely divergent from one another. |
|
prophyllar |
|
position |
|
Upon or otherwise directly associated with the prophylls (bracteoles, bractlets). |
|
crown-shaped |
= coroniform |
solid shape |
|
Shortly and broadly tubular overall, circumferentially continuous at the base, distally so or not; like a monarch's crown. |
|
rhombate |
= rhombic |
plane shape |
|
Broadest at the middle and more or less regularly attenuate to either end, the sides angled at the middle and more or less straight from there to either end. |
|
division |
? lobe, segment |
STRUCTURE |
|
Any generally convex, major peripheral protrusion or component sector that is delimited by concavities in the surface or margin and that is not proximally distinct from the remainder of the whole. |
|
extravaginal |
|
insertion |
|
Distal to or outside the leaf sheath. |
|
sporangium pl. sporangia |
= spore case |
STRUCTURE |
|
A spore-producing organ; basically capsular, often supported by a slender stalk (sporangiophore), often operculate (lidded). In Bryophyta and Polypodiophyta, a distinct portion of the sporangial wall effects regular dehiscence at maturity. Sporangia or their equivalents are also present, but of little or no descriptive significance, in seed plants. |
|
fungiform |
= mushroom-shaped |
solid shape |
|
Having a cylindric base and a considerably broader, pulvinate distal portion; like the generalized form of a mushroom. |
