solid shape |
|
Bulging unilaterally near the middle, as though with a belly. |
|
mucronate |
|
apex |
|
Terminating abruptly in a short, hard point that is a continuation of vascular tissue. See also apiculate, mucronulate. |

|
rugose |
= corrugate, wrinkled |
relief |
|
Having irregular, narrow ridges or creases, the intervening areas flat to shallowly concave or convex, appearing overall as though crumpled and then spread out. See also rugulose. |
|
shoot 1 |
|
STRUCTURE |
|
Collectively, all those portions of a plant body that are anatomically distinct from the root, the component axes differentiated into nodes and internodes, and branching exogenously from the former. |
|
staminodial |
|
insertion |
|
Upon or otherwise directly associated with the staminodes. |
|
hooked |
= hamate, uncinate |
apex |
|
Having a recurved terminal portion that resembles a hook. |
|
suture |
|
FEATURE |
|
An evident line of ontogenetic union. |
|
lacerate |
= cut, incised, torn; > laciniate, slashed |
plane shape |
|
Having straight to irregular lines of separation extending inward from the margin. See also cleft (dissected, divided, lobate, lobed, parted, partite, segmented). |
|
trunk |
= bole; < main stem, primary stem |
STRUCTURE |
|
The relatively stout, columnar, main stem of a distinct aboveground portion of a tree. |
|
wavy |
= undulate |
margin |
|
Having regular, curved, smoothly connected, alternating, wave-like deviations upward and downward from the general plane of the structure. |
|
barb 1 |
|
STRUCTURE |
|
Any relatively short, stiff, sharp, acutely inserted or bent, antrorse or retrorse, terminal or lateral appendage. |
|
microsporocarp |
|
STRUCTURE |
|
A sporocarp that bears only microsporangia. |
|
calyx tube |
|
STRUCTURE |
|
A relatively narrow, fully connate portion of a synsepalous (gamosepalous) calyx proximal to a broader portion (limb) that comprises the distinct or connate distal portions of the sepals. |
|
oily 2 |
= greasy, oleaginous, unctuous |
texture |
|
Liquid or deformably solid, cohesive, and slippery to the touch. |
|
cryptic |
|
coloration |
|
Similar to its natural background, from which it is not readily distinguished. |
|
pseudoaxillary |
|
insertion |
|
Only apparently axillary; originally extraaxillary but displaced to the axil by differential growth during development. |
|
dot |
= punctum |
FEATURE |
|
A small, generally round sector of distinct coloration or relief. |
|
ridged |
|
solid shape |
|
Having one or more ridges; esp. fruits of Apiaceae (Umbelliferae). |
|
falcate 2 |
= sickle-shaped |
solid shape |
|
Elongate, strongly compressed, and arcuate in the plane of compression, the two faces more or less plane and parallel, the degree of curvature decreasing distally or not; like a sickle blade. |
|
septal |
|
insertion |
|
Upon or otherwise directly associated with the septum or septa. |
|
furcate |
= forked; > bifurcate |
solid shape |
|
Having two or more terminal, antrorse branches or divisions arising from a common point or level, like the prongs of a fork. |
