hypanthium 1 (broad sense) pl. hypanthia |

STRUCTURE |
|
A complex structure comprising fused portions of the perianth and/or androecium of a flower, sometimes also including receptacular tissue; surrounding and wholly, partly, or not at all adnate to the gynoecium; subdivided morphologically into casing, collar and/or neck; sometimes bearing free distal portions of the constituent structures. |

Greenish pruinose; covered with a thin, opaque, greenish deposit (bloom) of macroscopically indistinguishable waxy particles that rubs off easily. See also glaucescent, glaucous. |
|
spiny 2 |
= aculeate, spinose |
margin |
|
Having slender, stiff, sharp projections oriented in the general plane of the structure. |
|
pollen |
|
STRUCTURE |
|
Collectively, the spores or grains produced within the thecae of anthers, each containing a very small microgametophyte (or its evolutionary homologue); serving as disseminules from which microgametes are released after transport to a receptive micropylar pollen droplet (in Pinophyta) or stigma (in Magnoliophyta) by a variety of vectors, notably wind, water, insects, bats, and birds. |
|
limb 2 |
|
STRUCTURE |
|
The portion of the corolla of a bisexual or staminate disc floret distal to the level of filament insertion; in Asteraceae (Compositae). |
|
trullate |
= trowel-shaped, trulliform |
plane shape |
|
Broadest below the middle, more or less straightly attenuate to either end, the sides angled at the level of greatest width; like the blade of a mason's trowel. See also obtrullate, obtrulliform. |
|
rounded |
|
base |
|
Convex overall and more or less regularly curved. |
|
dome-shaped |
= tholiform |
solid shape |
|
Convex overall, broadest at the base, and transversely more or less circular to elliptical throughout. |
|
…gonal |
= …angular |
plane shape |
|
Having more or less straight sides of the number indicated by the prefix; as in pentagonal, trigonal. See also deltate, …gonous (…angled). |
|
obvolute 2 |
|
vernation |
|
Conduplicate with the lateral edges of each leaf alternately overlapping those of the oppositely oriented, distally next adjacent one. |
|
stomium pl. stomia |
= stomatal pore |
FEATURE |
|
The opening in the wall of a sporangium, between the lip cells, through which the spores exit; in Psilotophyta, Lycopodiophyta, Equisetophyta, Polypodiophyta. |
|
erose 1 |
|
margin |
|
Having rough, very irregular depressions throughout. |
|
putrid |
= fetid |
odor |
|
Stinking like rotting flesh. |
|
cryptic |
|
coloration |
|
Similar to its natural background, from which it is not readily distinguished. |
|
auriform |
= ear-shaped |
solid shape |
|
Resembling a mammalian outer ear. |
|
microphyll |
|
STRUCTURE |
|
A small, lateral, leaf-like enation that, evolutionarily, is not a true leaf, i.e., whose vasculature, if any, consists of only a single median strand not ontogenetically integral with the vasculature of the bearing stem and not associated with leaf gaps in the stele of the stem; in Bryophyta, Psilotophyta, Lycopodiophyta, Equisetophyta. |
|
veinlet |
|
STRUCTURE |
|
A strand belonging to the ultimate (least in diameter) order of vasculature in a leaf or other basically laminar structure when that order consists of strands ending freely within areoles and/or connecting distally by pairs across areoles; absent in some taxa. See also costa (rib), lateral vein, midvein (midnerve, midrib), primary vein, secondary vein, tertiary vein, vein (nerve). |
|
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. |
|
partial |
|
extent |
|
Not reaching fully from the ovary wall or pericarp to the center of the ovary or fruit and/or from the apex to the base of its interior, thus not completely separating adjacent locules, which are recognized and delimited by extrapolating from the incomplete septal boundary(ies), the ovary or fruit nonetheless effectively unilocular. |
|
acephalous 2 |
= headless |
solid shape |
|
Not terminating in a head-like portion, esp. when one might be expected. |
|
ribbed 2 |
|
solid shape |
|
Having two or more prominent, elongate, relatively narrow, essentially parallel protrusions that extend over all or most of its length or circumference. |
|
obcompressed |
< flattened |
solid shape |
|
Flattened adaxially and abaxially, parallel to the longitudinal axis, as though pressed or squeezed from the upper and lower surfaces, the external surface otherwise basically convex. Used alone, this term usually implies a strong degree of flattening; otherwise, it is often used in combination with some other term that describes the overall shape exclusive of ("before") flattening, e.g., obcompressed-lanceoloid. See also compressed (complanate), depressed. |
