Indicating presence of or constitution by twelve entities of the type denoted by the term's stem; as in twelve-loculed, twelve-stamened, twelve-styled. |
|
annulus 1 pl. annuli |

STRUCTURE |

A small ring-like protrusion from the strobilar stalk near its base and below the lowermost sporangiophores, sometimes bearing small sporangia; esp. in Equisetum. |
|
…morphic |
|
architecture |
|
Existing within the taxon in the number of distinct structural states indicated by the prefix, the states segregated in different sets of plants or not; as in monomorphic, polymorphic, trimorphic. |
|
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. |
|
osseous |
= bony |
texture |
|
Very hard and rather brittle, like bone. |
|
compact |

architecture |
|
Having equivalent constituent parts disposed very near to one another. |
|
pinna pl. pinnae |
< leaflet |
STRUCTURE |
|
One of the first-order divisions or leaflets of a pinnate frond; in Polypodiophyta. See also pinnule. |
|
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. |
|
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. |
|
ear-shaped |
= auriform |
solid shape |
|
Resembling a mammalian outer ear. |
|
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. |
|
axile |
|
placentation |
|
Upon the central axis of a compound, plurilocular ovary. |
|
mericarp |
= coccus |
STRUCTURE |
|
One of the segments of a dehisced schizocarp; usually one-seeded and itself indehiscent. |
|
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. |
