Disposed in vertical sequence with long axes horizontal and parallel. |
|
scimitar-shaped |
= acinaciform |
solid shape |
|
Thin and moderately arcuate with two opposite, plane, broad faces, the degree of curvature increasing distally, thinnest at the convex edge, thicker toward the concave; like a scimitar blade. |
|
turbinate |
= top-shaped |
solid shape |
|
Broadly obovoid-obconic; like a spinning top. See also pyriform (pear-shaped), obturbinate. |

Finely dentate (toothed). See also crenate (scalloped), crenulate (small-scalloped), serrate (sawtoothed), serrulate (small-sawtoothed). |
|
pulviniform |
= cushion-shaped, mound-shaped, pulvinate |
solid shape |
|
Essentially round in transverse section, much broader than long or high, with a convex distal face that intersects either a more or less plane proximal face or, when the structure is sessile, its bearing surface. |
|
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. |
|
dusty |
= lentiginose, lentiginous |
coating |
|
Covered with a more or less even deposit of minute, dry, macroscopically indistinguishable particles. See also powdery (pulverulent), which is not clearly distinct in its application. |
|
interpetiolar |
< nodal |
position |
|
Upon the stem between the bases of opposite leaves. |
|
stiff |
= rigent, rigid |
texture |
|
Strongly resisting deformation over its length. |
|
elastoviscin |
= viscin |
SUBSTANCE |
|
A sticky, elastic material, especially that forming the threads that sometimes connect pollen grains. |
|
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. |
|
vexillate |
|
aestivation |
|
Having a larger member oriented more or less perpendicular to and folded about the others. |
|
channeled |
= canaliculate |
solid shape |
|
Having a longitudinal, transversely rounded depression; esp. a petiole or petiolule. |
|
overlapping 1 |
= imbricate(d) |
aestivation |
|
Having members whorled or spirally inserted and overlapping one another, each overlapping or overlapped to either side, and also above or below if spirally arranged or in multiple whorls. |
|
areolate |
|
relief |
|
Having numerous, small, irregularly disposed, transversely angular, shallow depressions or low protrusions overall. |
|
sapwood |
|
STRUCTURE |
|
That portion of the wood (xylem) of a stem or root whose cells are still living and functional; concentric about the heartwood once the latter has begun to form. |
|
bract 1 (broad sense) |
> bracteole, bractlet, phyllary, prophyll(um); >< scale |
STRUCTURE |
|
Any lateral structure ontogenetically and anatomically analogous with, and therefore presumably homologous with, but relatively smaller than, a leaf, especially when subtending an inflorescence, other reproductive structure, or portion thereof; putatively, an evolutionarily reduced leaf. |
|
cylindric(al) |
|
solid shape |
|
Solid and transversely round with a more or less uniform diameter, the ends blunt. |
|
conspicuous |
> showy |
manifestation |
|
Prominently evident. |
|
induplicate |
|
aestivation |
|
Basically valvate but with each member involute, the lateral abaxial surfaces of adjacent members contiguous. |
|
serrulate |
= small-sawtoothed |
margin |
|
Finely serrate (sawtoothed). See also crentate (scalloped), crenulate (small-scalloped), dentate (toothed), denticulate (small-toothed). |
