Interruptedly glossy (laevigate, lustrous, polished, shining, shiny, and thus sparkling when viewed from changing angles. |
|
partite |
? cleft, dissected, divided, lobate, lobed, parted, segmented |
plane 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 protrusions 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). |

|
The relatively large, erect adaxial (upper) petal in a papilionaceous corolla. |

|
solid shape |
|
Halved, figuratively; bilaterally asymmetric, nearly or wholly lacking one side as implicitly compared with some corresponding bilaterally symmetric structure, real or imagined. |
|
areole 1 |
= areola |
STRUCTURE |
|
Any distinctive surficial discontinuity of generally circular outline, whether concave, flush, or convex; when protuberant, sometimes bearing trichomes or spines, as in some Cactaceae. This term is used only when such entities are deemed structurally distinctive enough to merit description in their own rights, rather than as aspects of the surface. |
|
lenticel |
|
STRUCTURE |
|
A specialized, anatomically distinct structure within the periderm of a stem, consisting of comparatively spongy, sometimes suberized tissue distinct from others of the periderm; extending radially through the periderm and visible as a circular to elongate discontinuity in the color, texture, and/or relief of the outer surface of the stem; serving as a conduit for gas exchange between the stem interior and the atmosphere. |
|

coloration |
|
Transmitting light uniformly and diffusely. See also transparent. |
|
five-… |
= penta… |
prefix |
|
Indicating presence of or constitution by five entities of the type denoted by the term's stem; as in five-grooved, five-stamened, five-tepaled. |
|
scrotum-shaped |
= scrotiform |
solid shape |
|
Saccate (bag-, pouch- or sack-shaped) and somewhat swollen bilaterally in the distal portion; like a scrotum. |
|
coloration |
|
CHARACTER |
|
Hue(s), intensity(ies), and/or pattern (if any) of coloring. When more than one hue and/or intensity is involved, a term describing the pattern of contrast will be applicable, and the description as a whole should be phrased to indicate the particular role of each in the pattern; e.g., "ovaries striate, yellow on green"; "petals pink, spotted yellow basally"; "sepals green, suffused with red". |
