plane shape |
|
Basically triangular with an acute apex and two large, widely divergent basal lobes, each generally triangular and distally acute; like the stylized outline of the broad lateral face of a halberd head. |

|
lens-shaped 2 |
= biconvex, lenticular |
solid shape |
|
Relatively thin with two round, convex, opposite broad faces intersecting acutely at the circumferential edge; like a double-convex lens. See also disciform (discoid), meniscoid. |
|
unifacial |
|
architecture |
|
Having two opposite broad surfaces that are essentially similar in appearance. |
|
acerose |
= acicular, needle-shaped |
solid shape |
|
Rounded in cross-section and very slenderly elongate, broadest near the middle, and gradually attenuate to an acute apex and a slightly blunter base; like a needle. |
|
location |
|
CHARACTER |
|
Position with respect to aspects of environmental context. |
|
blistered |
= bullate, puckered, pustulate |
relief |
|
Having relatively coarse, irregularly disposed, rounded protrusions or convexities resembling blisters. See also papillate (papillose). |
|
nectar |
|
SUBSTANCE |
|
An aqueous exudate of high sugar content. |
|
cell 2 (not recommended) |
= chamber (not recommended), locule |
FEATURE |
|
Any structurally distinct compartment within an anther, ovary, fruit, sporangium or other organ; not necessarily having any evolutionary integrity. |
|
pandurate |
= fiddle-shaped |
plane shape |
|
Basically obovate but with deep, rounded sinuses opposite one another in the proximal half; like the frontal outline of an inverted fiddle body. |
|
planoconvex |
|
solid shape |
|
Relatively thin with opposite broad faces, one plane and one convex. |
|
dentate |
= toothed |
margin |
|
Having regularly spaced, angular convexities oriented more or less perpendicular to the generalized perimeter. See also crenate (scalloped), crenulate (small-scalloped), denticulate (small-toothed), serrate (sawtoothed), serrulate (small-sawtoothed). |
|
endophytic |
|
habit |
|
Growing within some portion of another, unrelated, living plant. |
|
flagelliform |
= whip-like |
solid shape |
|
Very slender, terete, generally straight, and apparently supple. |
|
sinistrorse |
= leftward |
orientation |
|
Directed to the left, relative to the direction of growth along an explicit or implicit axis of reference. See also dextrorse (rightward). |
|
lancehead-shaped 2 |
= lanceoloid, lanciform |
solid shape |
|
Considerably longer than broad, compressed or not, broadest near the base and somewhat concavely attenuate to the apex, the attenuation in all median longitudinal planes or else largely confined to one, depending upon the extent of compression, if any. See also oblanceoloid (oblanciform). |
|
turnip-shaped |
= napiform |
solid shape |
|
Depressed-globose overall and strongly concave-tapered (acuminate) at the base; like the generalized form of a turnip. |
|
annular |
= ring-shaped |
solid shape |
|
More or less evenly tubular in a closed circle; like a ring or doughnut. |
|
comose |
|
pubescence |
|
