costa pl. costae |
= rib; > midnerve (not recommended), midrib, midvein; >< lateral vein |
STRUCTURE |
|
A primary vein of a laminar structure, having a longitudinal course, either medial or lateral, often prominent. See also secondary vein, tertiary vein, veinlet. |
paired |
= conjugate, geminate |
arrangement |
|
Inserted by pairs, the members of each fused or not. |
incurved |
|
orientation |
|
Curving adaxially. See also decurved. |
subtending |
|
position |
|
Arising from the axis just below and very near to the base of some other specified lateral structure. This term is meaningless if the structure that is subtended is not indicated. |
fasciculate 2 |
= bundled (not recommended), fascicled |
arrangement |
|
Disposed in one or more fascicles, the members of each inserted close together and only slightly if at all divergent from one another. |
mamillate |
|
relief |
|
Bearing mamillae. |
unctuous 2 |
= greasy, oily, oleaginous |
texture |
|
Liquid or deformably solid, cohesive, and slippery to the touch. |
circumcaulous |
|
insertion |
|
Upon and surrounding the stem. |
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. |
dendritic |
= tree-like |
architecture |
|
Like the branched axial structure of a tree. |
lacunate |
|
relief |
|
Having relatively large and deep depressions overall. |
tessellate 1 |
= checkered |
coloration |
|
Having a pattern of more or less regularly disposed square zones of contrasting hues and/or intensities. |
bristled |
= aristate, awned |
apex |
|
Bearing one or more bristles (aristae, awns, setae). |
foveate |
= pitted |
relief |
|
Having numerous, small, rounded depressions. See also foveolate (fine-pitted, scrobiculate). |
saddle-shaped |
= selliform |
solid shape |
|
Relatively thin, broad and long, strongly compound-curved, concavely from end to end and convexly from side to side; like the generalized shape of a saddle. |
contortuplicate 1 |
= torsive |
aestivation |
|
Plicate and contorted. |
halberd-head-shaped 2 |
= hastate |
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. |
porosity |
|
CHARACTER |
|
Presence and disposition of vessels (pores) in wood (xylem). |
lobed |
? cleft, dissected, divided, lobate, parted, partite, segmented |
solid 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). |
caudicle |
= translator arm |
STRUCTURE |
|
An attenuate end portion by which a pollinium adheres to a pollinating insect, either directly or by means of a terminal viscidium, the latter, when present, sometimes attached by an intervening stipe; esp. in Asclepiadaceae, Orchidaceae. |
septum pl. septa |
> dissepiment, replum, trabecula |
STRUCTURE |
|
A topologically and/or texturally distinct wall or partition that separates chambers or locules within an ovary, fruit or sporangium. |
barbed 2 |
|
solid shape |
|
Having one or more relatively short, stiff, acutely inserted or bent, antrorse or retrorse, terminal and/or lateral hook-like appendages; esp. awns or setae. |
peduncle |
<stalk, stipe (broad sense, not recommended) |
STRUCTURE |
|
The common stalk, when present, of a compound inflorescence or first-order subunit thereof, or of a solitary flower that is deemed to represent an evolutionarily reduced compound inflorescence. |
hypochilium |
|
STRUCTURE |
|
The proximal portion of a labellum (lip) that has distinct proximal, distal, and sometimes also central parts; in Orchidaceae. See also epichilium, mesochilium. |
blistered |
= bullate, puckered, pustulate |
relief |
