|
orientation |
|
Directed forward or upward, toward the distal end of the context of reference, parallel or at an acute angle to the bearing structure. |
naked 1 |
|
architecture |
|
Lacking a covering that might have been expected. |
diaphragmed |
|
architecture |
pith |
Uninterrupted by cavities but heterogeneous in texture at axis maturity, with sectors of spongy tissue separated by relatively thin transverse plates of denser tissue that occur at the nodes or are otherwise regularly spaced along the axis. |
monochlamydeous |
|
architecture |
flower |
Having a monocyclic perianth. |
supramedial |
|
position |
|
Just above the middle of the structure in point. |
asymmetric(al) 1 |
|
architecture |
|
Not divisible into essentially equal halves along any line or plane. |
decurrent |
|
base |
laminar structure |
Having the lamina prolonged and adherent to the supporting axis beneath the point of vascular insertion, the prolonged portion termed a sterigma. |
oblong 2 |
|
solid shape |
|
Compressed-ellipsoid, the sides approximately parallel from near one end to near the other. See also ellipsoid(al). |
dorsiventral |
|
architecture |
|
Having structurally distinct abaxial (dorsal) and adaxial (ventral) portions or aspects. |
areolate |
|
relief |
|
Having numerous, small, irregularly disposed, transversely angular, shallow depressions or low protrusions overall. |
non-porous |
|
porosity |
|
Lacking vessels, the tracheary elements limited to tracheids and, sometimes, fiber-tracheids. |
disciform 2 |
|
architecture |
capitulum (head) |
Bearing one or more peripheral series of florets that are usually pistillate and that have relatively slender actinomorphic corollas, and one or more central series of florets that are bisexual or functionally staminate and that have relatively broader actinomorphic corollas; in Asteraceae (Compositae). |
pachycaulous |
|
architecture |
plant |
Having thick, more or less succulent stems. |
barb 2 |
|
STRUCTURE |
|
A trichome terminated by one or two small, relatively short, stiff, sharp, acutely reflexed appendages. |
trilete |
|
architecture |
spore |
Having a triradiate tetrad scar. |
elaiosome |
|
STRUCTURE |
|
A fleshy outgrowth from the seed coat (testa) that contains a high proportion of oil, usually attracting ants for dispersal. |
extrafloral |
|
insertion |
|
Outside and proximal to the flower; esp. nectaries. |
capitulescence |
|
architecture |
|
Mode or progressive pattern of bearing capitula (heads); most appropriately described using adjectival terms; esp. in Asteraceae (Compositae). |
equatorial ridge |

FEATURE |
|
A circumferential ring about a megaspore in the plane of its equator, raised above the remainder of the wall surface; in some heterosporous taxa of Polypodiophyta. |
…pinnate |
|
architecture |
foliaceous structure |
Compound with the number of orders of leaflets indicated by the prefix, each order pinnate; as in bipinnate, tripinnate. |
