conduplicate 2 |
= duplicate |
vernation |
|
Each leaf folded sharply inward along its longitudinal axis, the adaxial surfaces of each side facing one another. |
coma pl. comae, comas |
< tuft |
STRUCTURE |
|
A prominent single tuft of relatively long and slender, flexible, capillate trichomes; esp. from a seed, as in Asclepias (Asclepiadaceae). |
hooked |
= hamate, uncinate |
apex |
|
Having a recurved terminal portion that resembles a hook. |
strap-shaped |
= liguliform, lorate |
solid shape |
|
Elongate and relatively thin with the opposite faces more or less plane and moderately narrow, their edges more or less straight and parallel over most of their length; resembling a strap. |
dolabrate |
= axehead-shaped |
solid shape |
|
Like an axehead oriented cutting edge downward. This term is not semantically distinct from dolabriform, but botanically they have had somewhat different applications. |
pyriform |
= pear-shaped |
solid shape |
|
Basically circular in transverse section, broadest toward one end, attenuate toward and much narrower at the other, both ends rounded; slenderly turbinate or obturbinate; like a pear. |
microspore |
|
STRUCTURE |
|
A male spore; a spore of the smaller of the two types produced by the sporophytes of a heterosporous taxon; produced in a microsporangium; giving rise upon germination to a microgametophyte. |
velutinous |
= velvety |
pubescence |
|
Of or bearing dense, moderately firm, more or less erect, capillate trichomes, like velvet pile to the touch. |
apiculum 2 pl. apicula |
|
STRUCTURE |
|
The apex of a connective, when prolonged above the union of the anthers. |
carina 2 pl. carinae |
= keel |
STRUCTURE |
|
Collectively, the two relatively small, connate or coherent, abaxial (lower) petals that form the keel-like portion of a papilionaceous corolla. |
globular |
= globose, orbicular, rotund, spheric(al), spheroid(al) |
solid shape |
|
Uniformly convex, circular in any median section and in outline when viewed from any angle; like a globe or sphere. |
partite |
? cleft, dissected, divided, lobate, lobed, parted, 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 protrusions 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). |
crustaceous |
= crusty |
texture |
|
Thin, dry, hard, and brittle. |
symmetric(al) 1 |
|
solid shape |
|
Divisible into essentially equal halves along one or more lines or planes. |
acephalous 1 |
= headless |
architecture |
|
Not terminated or surmounted by a head-like structure, esp. when one might be expected. |
episepalous |
|
insertion |
|
Upon the sepals, or partially adnate thereto and apparently arising therefrom. |
rigent |
= rigid, stiff |
texture |
|
Strongly resisting deformation over its length. |
obcordiform |
|
solid shape |
|
Inversely cordiform (heart-shaped). |
pseudopetiole |
|
STRUCTURE |
|
A distinctly constricted, more or less stalk-like, proximal portion of a leaf, evolutionarily derived from the blade, the original petiole reduced to the point of absence or vestigiality; esp. in Poaceae (Gramineae). |
lenticular 1 |
= biconvex, lens-shaped |
plane shape |
|
Elongate, narrow, broadest at the middle, attenuate to acute ends, the sides convex; like the outline of a double-convex lens viewed from its edge. |
transparent |
< hyaline, pellucid |
coloration |
|
Transmitting light uniformly and without diffusion; clear, like glass. See also translucent. |
bent |
= flexed |
solid shape |
|
Having an abrupt bend at some point along its length. See also declinate (inclinate), geniculate (kneed), inflexed, reflexed. |
fixation |
|
CHARACTER |
|
Mode of attachment to a supporting structure. |
sculpture |
= relief |
CHARACTER |
|
General topographic aspect of a surface. Overlaps conceptually with solid shape. |
calyciform |
= cup-shaped, cupulate |
solid shape |
|
Truncate-globose with the distal margin more or less entire; like the bowl of a cup. |
