|
terete |

position |
|
Nodal and directly opposite the leaf. |
|
unciform |

= three-angled, triquetrous; > deltoid, obdeltoid |
solid shape |
|
Elongate with three sides that meet at acute or obtuse angles. |
|
abaxial |
= dorsal (not recommended) |
insertion |
|
On or pertaining to the side or portion of a lateral structure that faces (or would face) away from the bearing axis when (or if) the axis of the lateral structure is (or were) oriented in the same general direction as the bearing axis. |
|
apical |
< distal |
insertion |
|
At or very near the developmental end or tip (apex) of a structure. |
|
lip cell |
|
STRUCTURE |
|
Either of a pair of adjacent, narrow, transversely oriented, thick-walled cells bordering the pore (stomium) of a sporangium. |
|
bifacial |
|
architecture |
|
Having two opposite broad surfaces that differ distinctly in appearance. |
|
mushroom-shaped |
= fungiform |
solid shape |
|
Having a cylindric base and a considerably broader, pulvinate distal portion; like the generalized form of a mushroom. |
|
catadromous |
|
venation |
|
Having the first lateral vein in each pinna or primary segment of the frond arise from its midvein on the side toward the base of the frond, the pinnule or secondary segment that it leads to often disproportionately larger than the next distal ones. |
|
paleaceous |
= chaffy |
pubescence |
|
Of or bearing small, thin, more or less erect, chartaceous (papery) to membranous, planate trichomes. |
|
conic(al) |
= cone-shaped |
solid shape |
|
Transversely round, essentially triangular in median longitudinal section, and broadest proximally. See also obconic(al). |
|
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. |
|
decurved |
|
orientation |
|
Curving abaxially. See also incurved. |
|
decussate |
|
arrangement |
|
Opposite with successive pairs radially oriented at right angles to one another, thus polystichous with four equidistant ranks. |
|
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. |
|
fissure |
|
FEATURE |
|
A relatively narrow, split or crack in the outer tissue(s) of a structure. |
|
lamella pl. lamellae |
|
STRUCTURE |
|
A thin layer of tissue that forms a plate within tissue of lesser density or between areas of empty space. |
|
tubular |
|
solid shape |
|
Cylindric or attenuate-cylindric overall and with a hollow interior open at one or both ends. |
|
whorl |
= cycle, series, verticil |
STRUCTURE |
|
A set of three or more lateral structures that are inserted around an axis at the same level. |
