Basically obovate but with deep, rounded sinuses opposite one another in the proximal half; like the frontal outline of an inverted fiddle body. |
snail-shell-shaped |
= cochleate |
solid shape |
|
Relatively broad and short, basically round in transverse section, resembling a rapidly tapering spire overall, the exterior helically convoluted. |

plane shape |
|
Elongate and narrow with the sides more or less straight and parallel over most of its length. |
calyculus 1 pl. calyculi |
= epicalyx |
STRUCTURE |
|
A whorl of bracts immediately subtending (beneath or outside) a calyx; literally, a little calyx. |
pustule |
= blister, bulla |
FEATURE |
|
A relatively coarse, rounded protrusion or convexity. See also papilla. |
veinlet |
|
STRUCTURE |
|
A strand belonging to the ultimate (least in diameter) order of vasculature in a leaf or other basically laminar structure when that order consists of strands ending freely within areoles and/or connecting distally by pairs across areoles; absent in some taxa. See also costa (rib), lateral vein, midvein (midnerve, midrib), primary vein, secondary vein, tertiary vein, vein (nerve). |
pale 1 |
= palea, palet, receptacular bract |
STRUCTURE |
|
A small papery (chartaceous) to membranous bract borne on the compound receptacle of a capitulum (head) in Asteraceae (Compositae). |
trophophyll |
= sterile frond |
STRUCTURE |
|
A frond that does not bear sporangia; in Polypodiophyta. See also fertile frond. |
elaiosome |
|
STRUCTURE |
|
A fleshy outgrowth from the seed coat (testa) that contains a high proportion of oil, usually attracting ants for dispersal. |
faceted |
|
solid shape |
|
Having numerous, relatively small, flat or shallowly curved portions of the external surface that are bounded by more or less distinct angular discontinuities in that surface. |
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). |
porosity |
|
CHARACTER |
|
Presence and disposition of vessels (pores) in wood (xylem). |
adaxial |
= ventral (not recommended) |
position |
|
On or pertaining to the side or portion of a lateral structure that faces (or would face) toward the bearing axis when (or if) the axis of the lateral structure is (or were) oriented in the same general direction as the bearing axis. |
sickle-shaped 1 |
= falcate |
plane shape |
|
Elongate and laterally arcuate with the lateral edges more or less concentric, the degree of curvature decreasing distally or not; like the outline of the face of a sickle blade. |
costal |
|
insertion |
|
Upon or otherwise directly associated with the costa(e) of a laminar structure. |
irregular 2 |
|
course |
|
Deviating asymmetrically from a straight line. |
perianth tube |
|
STRUCTURE |
|
A relatively narrow, fully connate portion of a syntepalous (gamotepalous) perianth proximal to a broader portion (limb) that comprises the distinct or connate distal portions of the tepals. |
strigose |
|
pubescence |
|
Bearing sharp, rigid, appressed, capillate trichomes. See also strigillose (strigulose). |
pseudoaxillary |
|
position |
|
Only apparently axillary; originally extraaxillary but displaced to the axil by differential growth during development. |
tapered |
= attenuate |
solid shape |
|
Gradually diminishing in width or diameter from one end to the other. |
trapeziform |
|
plane shape |
|
Four-sided and either asymmetrical or bilaterally symmetrical like a triangle truncated distally perpendicular to its central axis. |
basipetal |
|
development |
|
Proceeding toward the base, thus more advanced apically or distally than basally or proximally within a given frame of reference. |
