branchlet |
|
STRUCTURE |
|
A branch of the highest or ultimate order. |
|
hair-like |
= capillary, capillate |
solid shape |
|
Finely filiform; resembling a hair. |
|
spot |
= blotch, macula |
FEATURE |
|
An area that differs in color from the rest of a structure's surface, usually due to differing coloration. See also eyespot. |
|
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. |
|
pore |
|
FEATURE |
|
A small aperture or opening in a wall or covering that allows transport between interior and exterior. |
|
lobed |
? cleft, dissected, divided, lobate, parted, partite, segmented |
plane shape |
|
Having one or more component sectors or peripheral protrusions that is/are delimited by concavities in the surface or margin and that is/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). |
|
enzymatic |
|
exudation |
|
Secreting a digestive exoenzyme; in carnivorous plants. |
|
arrowhead-shaped 2 |
= sagittate |
plane shape |
|
Generally triangular, tapering gradually from the base to an acute apex, the base with a relatively large, acute, retrorse lobe to either side; like the outline of the broad lateral face of an arrowhead. |
|
foliar |
|
position |
|
Upon or otherwise directly associated with the leaves. |
|
pedicel |
< stalk |
STRUCTURE |
|
The stalk, when present, of a single flower, except when the flower is solitary and deemed to represent an evolutionarily reduced compound inflorescence borne directly upon a peduncle. |
|
catadromous |
|
venation |
|
Having the first lateral vein in each pinna or primary segment of the frond arise from its midvein on the side toward the base of the frond, the pinnule or secondary segment that it leads to often disproportionately larger than the next distal ones. |
|
hypanthium 2 (strict sense) pl. hypanthia |
= floral cup (strict sense) |
STRUCTURE |
|
A marginal protrusion from or enlargement of the receptacle (torus) of a flower, encircling and wholly, partly or not at all adnate to the gynoecium, bearing the perianth and androecium. |
|
strobilus pl. strobili |
= cone; > female cone, macrostrobilus (not recommended), male cone, megastrobilus, microstrobilus |
STRUCTURE |
|
A compound or complex reproductive structure consisting of a central axis bearing congested sporophylls and sometimes other lateral members (e.g., bracts) that are sterile. |
|
crest |
= crista |
STRUCTURE |
|
A laterally elongate, relatively thin, irregular or notched, apical protrusion. |
|
apiculum 1 pl. apicula |
|
STRUCTURE |
|
A short, slender, angular tip that is not notably harder or stiffer than the main body of the bearing structure. See also mucro. |
|
verticil |
= cycle, series, whorl |
STRUCTURE |
|
A set of three or more lateral structures that are inserted around an axis at the same level. |
|
gongylodate |
= gongyloid, knob-shaped, knot-shaped, nodiform |
solid shape |
|
Approximately globose, the surface convoluted or not, like a knob or knot; usually applied only to structures or components that are relatively small. |
|
spicy |
|
odor |
|
Pleasantly pungent, reminiscent of spices. |
|
climbing root |
< aerial root |
STRUCTURE |
|
An aerial, usually adventitious root that, by some means, serves to anchor a climbing shoot portion to the structure(s) that support(s) it above ground level. |
|
platter-shaped |
= scutellate, scutelliform |
solid shape |
|
Relatively thin with opposite broad oval faces, shallowly concave-convex; like a serving platter. See also buckler-shaped (scutate, scutiform), which is not clearly distinct in its application. |
|
rosette |
|
STRUCTURE |
|
A set of leaves that are strongly congested and disposed in radial symmetry about the main stem at or very near its base, seeming to arise at the same level and often overlapping laterally; esp. the overwintering leaves of perennial herbs. |
|
eglandular |
= glandless |
architecture |
|
Lacking glands. |
|
oblong 2 |
|
solid shape |
|
Compressed-ellipsoid, the sides approximately parallel from near one end to near the other. See also ellipsoid(al). |

|
hippocrepiform |
= horseshoe-shaped |
solid shape |
|
Relatively slender and strongly compressed, the whole strongly curved over its length in a plane perpendicular to the direction of compression and forming an incomplete circle, the ends somewhat straighter than the rest and parallel or nearly so; like a horseshoe. |
