groove |
= colpus, fossula, furrow, sulcus, vallecula |
FEATURE |
|
A longitudinal depression that is relatively shallow and narrow. |
stipule |
|
STRUCTURE |
|
Any distinct, relatively diminutive, more or less foliaceous structure inserted on a stem alongside a petiole, or on a petiole near its base, and ontogenetically closely associated with the leaf; usually occurring as one of a pair disposed one to either side of the petiole. |
tapered |
= attenuate |
solid shape |
|
Gradually diminishing in width or diameter from one end to the other. |
lateral |
|
position |
|
To, toward, at, or upon a side, not apical or basal. |
worm-shaped |
= vermiculate |
solid shape |
|
Basically cylindric, elongate, and slender with bluntly rounded ends, variously curved over its length. |
antheridium pl. antheridia |
|
STRUCTURE |
|
A male gametangium; a multicellular fertile organ of a mature gametophyte within which male gametes (antherozoids, spermatozoids) are produced and from which they are discharged, in some taxa forcibly, through a pore. Technically present but highly reduced and of no descriptive significance in Magnoliophyta and part of Pinophyta. |
beard |
|
STRUCTURE |
|
A growth of relatively long, erect, flexible, capillary trichomes from one or more limited sectors of a structure's surface. |
mucous 1 |
= mucilaginous; < glutinous |
coating |
|
Of a slimy substance, or becoming so upon wetting. |
carpel |
< macrosporophyll (not recommended), megasporophyll, pistil |
STRUCTURE |
|
A more or less abstract unit of floral structure conceptually equivalent to a simple pistil or its putative evolutionary precursor (megasporophyll) or derivative (constituent of compound pistil); often regarded as the basic evolutionary unit of the gynoecium. |
ovoid |
= egg-shaped |
solid shape |
|
Transversely circular, broadest near a bluntly rounded base, and convexly attenuate to a narrower rounded apex; like a fowl egg. See also obovoid. |
compressed |
= complanate; < flattened |
solid shape |
|
Flattened bilaterally, parallel to the longitudinal axis, as though pressed or squeezed from opposing sides, 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., compressed-ovoid. See also depressed, obcompressed. |
pinnule |
< leaflet |
STRUCTURE |
|
A second- or higher-order division or leaflet of a pinnate frond; a division of a pinna; in Polypodiophyta. |
punctum pl. puncta |
= dot |
FEATURE |
|
A small, generally round sector of distinct coloration or relief. |
eglandular |
= glandless |
architecture |
|
Lacking glands. |
rounded |
|
base |
|
Convex overall and more or less regularly curved. |
…fid |
? …cleft, …lobate, …lobed, …parted, …partite, …segmented |
solid shape |
|
Having the number of lobes, divisions or segments indicated by the prefix; as in bifid, quadrifid. |
glandless |
= eglandular |
architecture |
|
Lacking glands. |
staminal |
|
position |
|
Upon or otherwise directly associated with the stamens. |
hood-shaped |
= cucullate, cuculliform |
solid shape |
|
Convex or compressed-convex overall with a distal peak or ridge, relatively thin-walled and essentially hollow with the interior open to one side below the distal portion; resembling a hood or cowl. See also helmet-shaped (galeate, galeiform), which overlaps conceptually. |
surface |
|
FEATURE |
|
The exterior or bounding area or layer of any structure, regarded as being infinitely thin; usually described as to relief, reflectance, and/or vesture. |
labellum pl. labella |
< labium, lip |
STRUCTURE |
|
The third petal of a tripetalous flower when distinctively different from the other two, usually enlarged relative to them and/or differently shaped or colored, usually apparently the abaxial (lower) petal of the three due to resupination during ontogenesis; esp. in Orchidaceae. |
trumpet-shaped |
= tubiform |
solid shape |
|
Obteretely tubular with a relatively short distal flare (the limb if a perianth, calyx, or corolla). |
balding |
= glabrescent |
pubescence |
|
Becoming bald (glabrous, psilate) with age. |
micropyle |
|
FEATURE |
|
The small pore in the integuments of an ovule at its apex, through which the pollen tube grows; or the corresponding aperture or scar in the coat of the seed that develops subsequently. |
calyptrate |
|
architecture |
|
Having or constituting a calyptra. |
