|
greasy 2 |

Liquid or deformably solid, cohesive, and slippery to the touch. |

…-toothed 2 |

|
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. |
|
lentiginose |
= dusty, lentiginous |
coating |
|
Covered with a more or less even deposit of minute, dry, macroscopically indistinguishable particles. See also pulverulent (granuliferous, powdery), which is not clearly distinct in its application. |
|
involute 2 |
|
vernation |
|
Each rolled adaxially from the lateral margins. |
|
approximate |
= close |
arrangement |
|
Disposed relatively near to one another. |
|
channeled |
= canaliculate |
solid shape |
|
Having a longitudinal, transversely rounded depression; esp. a petiole or petiolule. |
|
zoned |
|
coloration |
|
Having two or more fairly distinctly delineated areas of contrasting hues and/or intensities. |
|
supple |
= flexible, pliable, pliant |
texture |
|
Able to bend over its length and/or breadth without structural disruption. |
|
scrobiculate |
= fine-pitted, foveolate |
relief |
|
Finely pitted (foveate). |
|
ray 1 |
< primary axis |
STRUCTURE |
|
A first-order axis within a compound umbel. |
|
central |
= medial, median |
position |
|
At, upon, or closely ranged about the structural or symmetrical midpoint or axis. |
|
hyphodromous |
= one-veined, single-veined |
venation |
|
Having one median, primary vein and no other venation externally evident. |
|
pith |
|
STRUCTURE |
|
The central ground tissue of a stem or, when present, of a root, consisting of thin-walled parenchyma cells; distinct and more or less soft and spongy relative to the other tissues of the axis; sometimes partly or wholly degenerating after secondary growth has begun. |
|
buckler-shaped |
= scutate, scutiform |
solid shape |
|
Relatively thin with opposite broad oblong faces, planate to shallowly concave-convex, sometimes thickened about the periphery such that each face has a marginal rim; like an oblong shield. See also platter-shaped (scutellate, scutelliform), which is not clearly distinct in its application. |
|
glabrous |
= bald, psilate |
pubescence |
|
Lacking trichomes. |
|
testes-shaped |
= testicular |
solid shape |
|
Bilaterally symmetrical, each side essentially oblate and constrictedly confluent with the other; like the overall shape of a pair of mammalian testes. |
|
lanciform |
= lancehead-shaped, lanceoloid |
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 oblanciform (oblanceoloid). |
|
sigmoid 2 |
= S-shaped |
solid shape |
|
Elongate with more or less constant width or diameter and curved more or less regularly first in one direction and then in the opposite direction, like the letter S. |
|
corrugate 2 |
= rugose, wrinkled |
relief |
|
Having irregular, narrow ridges or creases, the intervening areas flat or only slightly concave or convex, appearing overall as though crumpled and then spread out. See also rugulose. |
|
base |
|
CHARACTER |
|
Configuration of the lowermost or proximal portion of a structure, its extent determined somewhat subjectively in relation to the shape of the structure as a whole. The concept of base varies from one descriptive context to another, since the base is not a clearly delimited, morphologically distinct entity. The terms for describing basal condition are not strictly coordinate logically — some are more inclusive than others, and some describe conditions involving what can be regarded as appendages — and precise characterization may require using more than one descriptor. The semantic antecedent of some descriptors is "base," whereas the antecedent of others is the structure as a whole (e.g., leaf ). |
|
powdery |
= granuliferous, pulverulent |
coating |
|
Covered with a more or less even deposit of fine, dry particles. See also dusty (lentiginose, lentiginous), which is not clearly distinct in its application. |
|
masculine |
= male |
reproduction |
|
Of the sex that produces microspores and sperm. |
