|
gynophore |
= hypogynium; < stalk, stipe (broad sense, not recommended) |
STRUCTURE |

|
indehiscent |
|
dehiscence |
|
Not splitting or forming an aperture at maturity, the contents being released for dispersal only after decay, digestion, or erosion of the structure. |

apex |
|
Having a recurved terminal portion that resembles a hook. |
|
bicolor(ous) |
< discolor(ous) |
coloration |
|
Having two surfaces of different colors; esp. leaves with differently colored adaxial and abaxial surfaces. |
|
abaxial |
= dorsal (not recommended) |
position |
|
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 |
position |
|
At or very near the developmental end or tip (apex) of a structure. |
|
muticous |
|
apex |
|
Lacking a distinct terminal point (when one might be expected). |
|
bifurcate |
< forked, furcate |
apex |
|
Having two terminal, antrorse branches or divisions arising from a common point or level, like the prongs of a fork. |
|
pithy |
= medullose |
texture |
|
Loose or spongy internally, denser and firmer externally. |
|
conjugate |
= geminate, paired |
arrangement |
|
Inserted by pairs, the members of each fused or not. |
|
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. |
|
tubular |
|
solid shape |
|
Cylindric or attenuate-cylindric overall and with a hollow interior open at one or both ends. |
|
lamella pl. lamellae |
|
STRUCTURE |
|
A thin layer of tissue that forms a plate within tissue of lesser density or between areas of empty space. |
|
whorl |
= cycle, series, verticil |
STRUCTURE |
|
A set of three or more lateral structures that are inserted around an axis at the same level. |
|
angular |
|
plane shape |
|
Having sides that meet at acute or obtuse angles. |
|
mono… |
= one-…, single-…, uni… |
prefix |
|
Indicating presence of or constitution by one entity of the type denoted by the term's stem; as in monandrous, monocolpate, monocyclic. See also entries for particular terms with this prefix whose meanings, at least in some applications, are more specific than usually indicated by such combination. |
|
bark |
|
STRUCTURE |
|
The outermost portion of any shoot or root axis having secondary growth, consisting of all those tissues outside the vascular cambium; sometimes exhibiting zonation into inner, living bark and outer, dead bark; usually described only as to external appearance. |
|
one-veined |
= hyphodromous, single-veined |
venation |
|
Having one median, primary vein and no other venation externally evident. |
