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. |
callus |
|
FEATURE |
|
A small, relatively hard covering, outgrowth, or swelling of tissue; esp. in axes of grass (Poaceae) inflorescences just distal to points of eventual disarticulation. |
obvolute 2 |
|
vernation |
|
Conduplicate with the lateral edges of each leaf alternately overlapping those of the oppositely oriented, distally next adjacent one. |
club-shaped |
= clavate |
solid shape |
|
Elongate and basically round in transverse section, the diameter greatest at or near a blunt apex, thence attenuate toward the base, the degree of taper greatest between the middle and the upper quarter. |
crowded |
= compact, congested |
architecture |
|
Having equivalent constituent parts disposed very near to one another. |
prophyllar |
|
insertion |
|
Upon or otherwise directly associated with the prophylls (bracteoles, bractlets). |
divided |
? cleft, dissected, lobate, lobed, parted, partite, segmented |
solid shape |
|
Having two or more component sectors or peripheral protrusions that are delimited by concavities in the surface or margin and that are not proximally distinct from the remainder of the whole. The meanings of this term and its approximate synonyms sometimes have been supposed to differ according to the depth of the delimiting concavities relative to the midline or midpoint of the overall structure, and/or to the shape or proportions of the protusions or sectors; however, there has been little consistency in the applications of the various terms according to such distinctions, which are ones only of degree and are necessarily arbitrary in any case. In general usage, these terms differ only indistinctly and connotatively: cleft, lobed (or lobate), parted (or partite) and segmented tend to connote fewer protrusions or sectors; lobate usually connotes as well a generally rounded shape; dissected tends to connote more numerous sectors that are elongate and angular. See also cut (incised, lacerate, torn), laciniate (slashed). |
rhizophore |
|
STRUCTURE |
|
A stem branch that bears no leaves and from which roots eventually arise; esp. in Selaginellaceae. |
extrafloral |
|
position |
|
Outside and proximal to the flower; esp. nectaries. |
semicraspedodromous |
|
venation |
|
Having a single median primary vein that branches to either side along the length of the lamina, each secondary vein running thence toward and bifurcate near the margin, one branch terminating at the margin, the other upwardly arcuate and merging with the superadjacent secondary vein, thus forming one of a series of marginal loops. |
full |
|
extent |
|
Reaching from the ovary wall or pericarp to the center of the ovary or fruit and from the apex to the base of its interior, thus separating adjacent locules completely. |
sporangiophore |
< stalk |
STRUCTURE |
|
A stalk that bears one or more sporangia. |
subtending |
|
insertion |
|
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. |
intruded |
|
placentation |
|
Upon partial septa excrescent from the wall of a compound, unilocular ovary. |
toothlet |
|
STRUCTURE |
|
A diminutive tooth (dens). See also sawtooth, sawtoothlet, scallop (crena), scalloplet (crenule). |
