insertion |
|
Upon the stems, each directly above (distal to) and very near a point of leaf insertion. |
|

solid shape |
|
Having knob-shaped (gongylodate, gongyloid, knot-shaped, nodiform) protrusions. See also nodulose. |

Producing sexually or asexually generated offspring that begin growth and development while borne upon the parent plant. |
|
anadromous |

venation |
|
Having the first lateral vein in each pinna or primary segment of the frond arise from its midvein on the side toward the apex of the frond, the pinnule or secondary segment that it leads to often disproportionately larger than the next distal ones. |
|
mesochilium |
|
STRUCTURE |
|
The central portion of a labellum (lip) that has distinct proximal, distal, and central parts; in Orchidaceae. See also epichilium, hypochilium. |
|
axis pl. axes |
|
STRUCTURE |
|
Any unitary and longitudinally continuous structure that bears laterally the subordinate portion(s), if any, of a plant root or shoot or any subdivision thereof and that represents the main line of structural development and/or symmetry distal to its origin, irrespective of the particular ontogenetic growth pattern involved. See also primary axis. |
|
microgametophyte |
|
PLANT |
|
A gametophyte whose fertile organs (gametangia) are all antheridia. |
|
octa… |
= eight-… |
prefix |
|
Indicating presence of or constitution by eight entities of the type denoted by the term's stem; as in octandrous, octocarpellate, octolocular. |
|
calyculus 1 pl. calyculi |
= epicalyx |
STRUCTURE |
|
A whorl of bracts immediately subtending (beneath or outside) a calyx; literally, a little calyx. |
|
coating |
|
CHARACTER |
|
Exudate that covers the surface proper. See also indumentum (vesture), pubescence. |
|
cruciate 2 |
= cross-shaped |
solid shape |
|
Having two elongate, basically straight portions intersecting at a point interior to the ends of each. |
|
dolabriform |
= axe-shaped |
solid shape |
|
Elongate, basally terete, becoming strongly compressed toward an abruptly and unilaterally broader apex; like an axe (handle plus head). This term is not semantically distinct from dolabrate, but botanically they have had somewhat different applications. |
|
rhytidomal |
|
insertion |
|
Within, upon, or otherwise directly associated with the bark. |
|
exudation |
|
CHARACTER |
|
Discharged substance, as to type. |
|
semiterete |
= half-terete |
solid shape |
|
Terete but flattened on one side. |
|
spore case |
= sporangium |
STRUCTURE |
|
A spore-producing organ; basically capsular, often supported by a slender stalk (sporangiophore), often lidded (operculate). In Bryophyta and Polypodiophyta, a distinct portion of the sporangial wall effects regular dehiscence at maturity. Spore cases or their equivalents are also present, but of little or no descriptive significance, in seed plants. |
|
subterranean |
= hypogeal, hypogeous |
location |
|
Within the ground, beneath its surface. |
|
tortuous |
|
course |
|
Strongly irregular with sharp bends and/or curves. |
|
velvety |
= velutinous |
pubescence |
|
Of or bearing dense, moderately firm, more or less erect, capillate trichomes, like velvet pile to the touch. |
|
aestivation |
|
CHARACTER |
|
Disposition of perianth (undifferentiated), calyx, or corolla members in the bud. |
|
ascidiform |
= pitcher-shaped |
solid shape |
|
Having a more or less tubular, radially or bilaterally symmetrical body closed at the base and broadening toward a more or less open apex sometimes lidded or overarched by a prolongation of one side; like a pitcher. |
|
obcordiform |
|
solid shape |
|
Inversely cordiform (heart-shaped). |
|
buckler-shaped |
= scutate, scutiform |
solid shape |
|
Relatively thin with opposite broad oblong faces, planate to shallowly concave-convex, sometimes thickened about the periphery such that each face has a marginal rim; like an oblong shield. See also platter-shaped (scutellate, scutelliform), which is not clearly distinct in its application. |
|
pectinate |
= comb-shaped |
plane shape |
|
Finely divided, the divisions slender, oriented more or less perpendicular to the central axis, and resembling the teeth of a comb. |
|
circinate 1 |
|
solid shape |
|
Terete and rolled downward from the apex in a tight coil. |
