oblong 2 |
|
solid shape |
|
Compressed-ellipsoid, the sides approximately parallel from near one end to near the other. See also ellipsoid(al). |
|
hippocrepiform |
= horseshoe-shaped |
solid shape |
|
Relatively slender and strongly compressed, the whole strongly curved over its length in a plane perpendicular to the direction of compression and forming an incomplete circle, the ends somewhat straighter than the rest and parallel or nearly so; like a horseshoe. |
|
stipe 2 (broad sense, not recommended) |
< stalk; > gynophore, hypogynium, peduncle, petiole |
STRUCTURE |
|
A stalk of or supporting a frond, inflorescence, or gynoecium. |
|
pulverulent |
= granuliferous, powdery |
coating |
|
Covered with a more or less even deposit of fine, dry particles. See also lentiginous (dusty, lentiginose), which is not clearly distinct in its application. |
|
megasporangium pl. megasporangia |
= macrosporangium (not recommended) |
STRUCTURE |
|
A sporangium that produces megaspores. |
|
extravaginal |
|
position |
|
Distal to or outside the leaf sheath. |
|
seed leaf |
= cotyledon |
STRUCTURE |
|
Any of the one or more primary foliar structures of an embryonic seed plant, proximal to all succeeding leaf primordia; sometimes serving as a storage organ for food reserves in the seed, as in peas and beans. |
|
caudate 2 |
= tailed |
base |
|
With one or more relatively slender, retrorse basal enations or appendages. |
|
papillose |
= papillate |
relief |
|
Having small, conoidal protrusions overall; appearing pimply. |
|
barbella pl. barbellae |
= barbel |
STRUCTURE |
|
A small barb. |
|
suprabasal |
|
insertion |
|
Just above the base of the structure in point. |
|
revolute 2 |
|
vernation |
|
Each rolled abaxially inward from the lateral margins. |
|
node |
|
STRUCTURE |
|
One of the evident sectors of a stem that occur sequentially along its length and from which leaves (megaphylls) and lateral branches arise exogenously. The anatomy of nodes differs from, but is not abruptly distinct longitudinally from, that of the intervening sectors (internodes), with which it is smoothly confluent and from which is distinguished by the lateral transit and egress of vascular traces interconnecting the stem and the leaves and branches that it bears. |
|
xylary |
|
position |
|
Within or otherwise directly associated with the wood. |
|
smooth 1 |
|
relief |
|
Even or unrelieved overall. Strictly applied, this term refers only to the surface proper; however, it is often used to mean glabrous as well. |
|
heart-shaped 3 |
= cordiform |
solid shape |
|
Having two rounded basal lobes, broadest near the base and fairly regularly attenuate to an essentially angular apex; like the stylized form of a heart. See also obcordiform. |
|
depressed |
< flattened |
solid shape |
|
Flattened distally, perpendicular to the longitudinal axis, as though pressed from the top, the external surface otherwise basically convex. Often used in combination with some other term that describes the overall shape exclusive of ("before") flattening, e.g., depressed-globose. See also compressed (complanate), obcompressed. |
|
…colpate |
= …fossulate, …furrowed, …grooved, …sulcate, …valleculate |
architecture |
|
Having the number of colpi indicated by the prefix; esp. pollen grains; as in monocolpate, polycolpate, 3-colpate. |
|
pinnule |
< leaflet |
STRUCTURE |
|
A second- or higher-order division or leaflet of a pinnate frond; a division of a pinna; in Polypodiophyta. |
|
bulblet |
= bulbil |
STRUCTURE |
|
A small bulb-like structure produced from a sterile or fertile plant structure other than a bulb, usually within a leaf axil, leaf sinus, or inflorescence, serving as a vegetative propagule. |
|
lax |
= loose |
architecture |
|
Having equivalent constituent parts disposed distant from one another. |
|
dotted 1 |
= punctate |
coloration |
|
Having small, round, clear or colored spots that contrast with the ground color. See also small-dotted (puncticulate). |
|
tomentulose |
|
pubescence |
|
Finely tomentose. |
|
…-scalloped |
= …crenate |
margin |
|
Having the number of orders of scallops (crenae) indicated by the prefix, one upon another; as in twice-scalloped. See also …-sawtoothed (…serrate), …-toothed (…dentate). |
|
attenuate 1 |
= concave-tapered |
base |
|
Gradually diminishing in width or diameter toward the proximal end, the sides longitudinally concave. Corresponds with acuminate for apex shape. |
