cupule |
|
STRUCTURE |
|
A cup-like structure inserted at the base of a fruit, partially enclosing it or not; composed of a persistent, usually dried, sometimes hardened involucre, perianth, or portion thereof, the constituent parts often coalescent, yielding a unitary structure. |
|
column foot |
= mentum |
STRUCTURE |
|
A lateral, often nectariferous protrusion from the proximal portion of a column, opposite the labellum, projecting in front of the rest of the flower; in Orchidaceae. |
|
pleated 2 |

vernation |
|
Having alternately adaxial and abaxial lengthwise folds, resembling a closed fan. |
|
lid |
= operculum |
STRUCTURE |
|
A distal, cover-like portion of a structure whose main body is otherwise closed, transversely discontinuous with the main body around most of the circumference, or becoming partially or wholly separate by transverse dehiscence; as of a pitcher (ascidium), pollen grain, pyxis, or spore case (sporangium). |
|
eucamptodromous |
|
venation |
|
Having a single median primary vein that branches to either side along the length of the lamina, the secondary veins upwardly arcuate, gradually becoming indistinct interior to the margin, and serially interconnected by cross-branches without formation of marginal loops. |
|
rostellate |
= small-beaked |
apex |
|
Diminutively rostrate (beaked). |
|
obovoid |
|
solid shape |
|
Inversely ovoid (egg-shaped). |
|
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. |
|
hirtellous |
|
pubescence |
|
Finely hirsute. |
|
pulvinate 2 |
= cushion-shaped, mound-shaped, pulviniform |
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. |
|
disk |
|
STRUCTURE |
|
See disc. |
|
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. |
|
megasporophyll |
= macrosporophyll (not recommended); > carpel, cone scale, ovuliferous scale |
STRUCTURE |
|
A sporophyll that bears only megasporangia and, in Pinophyta, naked ovules that develop subsequently. |
|
segment |
? division, lobe |
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. |
|
germination 1 |
|
CHARACTER |
|
The process wherein a dormant embryo resumes active metabolism and growth, the primary root and shoot emerging from the seed coat, the young sporophyte thereupon entering the seedling stage. |
|
pappus scale |
|
STRUCTURE |
|
A pappus element that is more or less planate and relatively thin and broad; may terminate in one or more awn- or bristle-like appendages. |
|
internodal |
|
insertion |
|
Upon or otherwise directly associated with the internodes. |
|
suprabracteal |
|
position |
|
Upon the axes, each directly above (distal to) and very near a point of bract insertion. |
|
epichilium |
|
STRUCTURE |
|
The distal portion of a labellum (lip) that has distinct proximal, distal, and sometimes also central parts; in Orchidaceae. See also hypochilium, mesochilium. |
|
