|
fertile frond |
< spore leaf, sporophyll |
STRUCTURE |
|
A frond that bears sporangia; in Polypodiophyta. See also sterile frond (trophophyll). |
|
setulose |
= hispidulous, small-bristly |
pubescence |
|
Finely setose (hispid). |
|
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. |
|
kneecap-shaped |
= patelliform |
solid shape |
|
Thickly meniscoid, like a human kneecap. |
|
trochlear |
= pulley-wheel-shaped |
solid shape |
|
Discoid (disciform) but with the circumferential surface concave between faces. |
|
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. |
|
calyciform |
= cup-shaped, cupulate |
solid shape |
|
Truncate-globose with the distal margin more or less entire; like the bowl of a cup. |
|
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. |
|
clustered 1 |
|
arrangement |
|
Disposed in one or more aggregates, the members of each inserted close together, thence widely divergent from one another. |
|
crown-shaped |
= coroniform |
solid shape |
|
Shortly and broadly tubular overall, circumferentially continuous at the base, distally so or not; like a monarch's crown. |
|
prophyllar |
|
position |
|
Upon or otherwise directly associated with the prophylls (bracteoles, bractlets). |
|
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. |
|
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. |
|
extravaginal |
|
insertion |
|
Distal to or outside the leaf sheath. |
|
fungiform |
= mushroom-shaped |
solid shape |
|
Having a cylindric base and a considerably broader, pulvinate distal portion; like the generalized form of a mushroom. |
|
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. |
|
subtending |
|
position |
|
Arising from the axis just below and very near to the base of some other specified lateral structure. This term is meaningless if the structure that is subtended is not indicated. |
|
involucel |
|
STRUCTURE |
|
One or more closely proximate whorls of bractlets (bracteoles, prophylls) immediately subtending (below or outside) a subordinate portion of an inflorescence that is subtended as a whole by an involucre, the bractlets often leaf-like, sometimes petaloid. |
|
top-shaped |
= turbinate |
solid shape |
|
Broadly obovoid-obconic; like a spinning top. See also pear-shaped (pyriform), obturbinate. |
|
velamen pl. velamina |
|
STRUCTURE |
|
A thin, often chartaceous (papery, papyraceous) or pergamentaceous (parchment-like), outermost tissue layer of an aerial root; esp. in Orchidaceae. |
|
aerial |
|
location |
|
Above ground or water level. |
|
manifestation |
|
CHARACTER |
|
Degree or nature of evidence when present within the context in point. |
