slashed |
= laciniate; < cut, incised, lacerate, torn |
plane shape |
|
Having relatively close, more or less straight lines of separation exending inward from the margin. See also cleft (dissected, divided, lobate, lobed, parted, partite, segmented). |
slipper-shaped |
= calceolate |
solid shape |
|
Relatively thin-walled with an essentially hollow interior that is open on one side at the broader end. |
collar 1 |
|
STRUCTURE |
|
The free portion (if any) of a floral tube, distal to its casing and/or neck when one or both is/are present. |
head-shaped |
= capitate, capitiform |
solid shape |
|
Basically globose and resembling a head in the context of occurrence. |
pilosulous |
|
pubescence |
|
Finely pilose. |
arcuate 2 |
|
plane shape |
|
Elongate and more or less regularly curved from one end to the other, one side convex, the opposite concave. |
embryotega pl. embryotegae, embryotegas |
|
STRUCTURE |
|
A small, hardened, lid-like portion of the testa (seed coat) at the micropyle of some seeds, detaching at germination. |
scabrous 1 |
= rough |
pubescence |
|
Of or bearing coarse, stiff, ascending trichomes and markedly rough to the touch. |
bracteole 1 |
= bractlet; < bract |
STRUCTURE |
|
A diminutive bract, or a bract that is smaller than others present. |
ovate |
= egg-shaped |
plane shape |
|
Elongate and wholly convex, widest near a bluntly rounded base and attenuate to a narrower rounded apex; like the lateral outline of a fowl egg. See also obovate. |
prominence |
|
CHARACTER |
|
Elevation or depression of a discrete feature relative to the surrounding surface. |
macrospore (not recommended) |
= megaspore |
STRUCTURE |
|
A female spore; a spore of the larger of two types produced by the sporophytes of a heterosporous taxon; produced in a megasporangium; giving rise upon germination to a megagametophyte. |
umbilicate |
|
solid shape |
|
Having a relatively small, transversely round, central depression in an essentially round broad face. |
frond |
< leaf, macrophyll (not recommended), megaphyll |
STRUCTURE |
|
A leaf in Polypodiophyta or Palmae (Arecaceae), usually relatively large and often highly dissected. Use of this term in preference to "leaf" in descriptions of ferns and palms is a matter of tradition only, not of morphological or evolutionary distinction. |
cladodromous |
|
venation |
|
Having a single median primary vein that branches to either side along its length, the secondary veins running thence toward the margin, but freely ramifying and becoming indistinct before reaching it. |
carpophore 2 |
= columella; < stalk |
STRUCTURE |
|
Any pedestal-like prolongation of a floral receptacle extending beyond the distalmost level of perianth insertion and bearing the gynoecium. |
periclinal |
|
orientation |
|
Parallel to some given plane of reference; applied especially to the plane of cell division when it is oriented parallel to the generalized plane of the structural surface. |
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. |
knotted |
= torulose |
solid shape |
|
Elongate and irregularly round in transverse section with narrow irregular constrictions and intervening, closely proximate gongyloid sectors, the whole straight or variously curved; serially gongyloid; like a sequentially knotted rope. |
ray 2 |
= lamina |
STRUCTURE |
|
The distal, relatively flat portion of the corolla of a ray floret, terminating in 0--4 teeth or lobes; in Asteraceae (Compositae). |
extent |
|
CHARACTER |
|
Reach of the septum or septa within the ovary or fruit, relative to the ovary wall or pericarp and its center. |
warty |
= tuberculate, tuberculose, verrucose |
relief |
|
Covered with small, relatively broad, irregularly shaped, obtuse protrusions. |
biconvex 2 |
= lens-shaped, lenticular |
solid shape |
|
Relatively thin with two round, convex, opposite broad faces intersecting acutely at the circumferential edge; like a double-convex lens. See also disciform (discoid), meniscoid. |
sporangium pl. sporangia |
= spore case |
STRUCTURE |
|
A spore-producing organ; basically capsular, often supported by a slender stalk (sporangiophore), often operculate (lidded). In Bryophyta and Polypodiophyta, a distinct portion of the sporangial wall effects regular dehiscence at maturity. Sporangia or their equivalents are also present, but of little or no descriptive significance, in seed plants. |
lip |
= labium; > labellum |
STRUCTURE |
|
Any substructure that resembles a lip, especially a portion of a perianth, calyx or corolla. |
