flower |
|
STRUCTURE |
|
A functionally integrated, complex structure comprising sets of sporophytic and/or associated sterile structures disposed in standard sequence along a common axis; consisting of one or more constituent members each of, in ascending (proximal to distal) order of insertion, perianth (tepals, or else sepals and/or petals), androecium (stamens, staminodes and/or other associated structures), and/or gynoecium (pistils and/or other associated structures), the foregoing all borne laterally from the distal portion (receptacle) of the axis; depending upon the combination of structures present, may be bisexual, staminate only, pistillate only, or sterile; characteristic of and unique to the Magnoliophyta (Angiospermae). When a fertile androecium and gynoecium are both present a flower is termed perfect. When perfect and also with calyx and corolla both present, a flower is termed complete. Both terms are somewhat archaic and of limited descriptive value. |
oily 2 |
= greasy, oleaginous, unctuous |
texture |
|
Liquid or deformably solid, cohesive, and slippery to the touch. |
horseshoe-shaped |
= hippocrepiform |
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. |
strigillose |
= strigulose |
pubescence |
|
Finely strigose. |
midvein |
= midnerve, midrib; < costa, nerve, rib, vein |
STRUCTURE |
|
A primary vein that runs longitudinally through the center of a leaf or other basically laminar structure. See also lateral vein, secondary vein, tertiary vein, veinlet. |
ventrifixed |
|
fixation |
|
Attached on the adaxial side well above the base. |
concave-tapered 2 |
= attenuate |
base |
|
Gradually diminishing in width or diameter toward the proximal end, the sides longitudinally concave. Corresponds with acuminate for apex shape. |
divided |
? cleft, dissected, lobate, lobed, parted, partite, segmented |
plane shape |
|
Having two or more component sectors or peripheral protrusions that are delimited by concavities in the surface or margin and that are not proximally distinct from the remainder of the whole. The meanings of this term and its approximate synonyms sometimes have been supposed to differ according to the depth of the delimiting concavities relative to the midline or midpoint of the overall structure, and/or to the shape or proportions of the protusions or sectors; however, there has been little consistency in the applications of the various terms according to such distinctions, which are ones only of degree and are necessarily arbitrary in any case. In general usage, these terms differ only indistinctly and connotatively: cleft, lobed (or lobate), parted (or partite) and segmented tend to connote fewer protrusions or sectors; lobate usually connotes as well a generally rounded shape; dissected tends to connote more numerous sectors that are elongate and angular. See also cut (incised, lacerate, torn), laciniate (slashed). |
basal |
< proximal |
position |
|
At or very near the developmental origin (base) of a structure. |
oblanciform |
= oblanceoloid |
solid shape |
|
Inversely lanciform (lancehead-shaped, lanceoloid). |
stiff |
= rigent, rigid |
texture |
|
Strongly resisting deformation over its length. |
cruciate 2 |
= cross-shaped |
solid shape |
|
Having two elongate, basically straight portions intersecting at a point interior to the ends of each. |
…pterous |
= …winged |
architecture |
|
Having the number of alae (wings) indicated by the prefix; as in dipterous, polypterous, tetrapterous. |
tree-like |
= dendritic |
architecture |
|
Like the branched axial structure of a tree. |
medial |
= central, median |
position |
|
At, upon, or closely ranged about the structural or symmetrical midpoint or axis. |
flagelliform |
= whip-like |
solid shape |
|
Very slender, terete, generally straight, and apparently supple. |
secondary root |
|
STRUCTURE |
|
Any root branch that originates directly or indirectly from a primary root. |
bundle scar |
|
FEATURE |
|
A smaller scar within the bounds of a leaf scar at the point where a vascular bundle traversed the abscission layer between stem and leaf. |
pannose |
< felted |
pubescence |
|
Bearing closely intertwined, capillate trichomes that form a dense, felt-like mat. See also panniform. |
alternate 1 |
|
arrangement |
|
Inserted singly along the axis, each at a different level and each diverging on a different radius than the ones next above and below. |
infructescence 1 |
|
STRUCTURE |
|
A mature (fruiting) inflorescence (static sense). |
reticulate 2 |
= netted |
coloration |
|
Having a pattern of interconnected fine lines of contrasting hue and/or intensity. |

= colpus, fossula, furrow, groove, sulcus |
STRUCTURE |
|
A longitudinal depression that is relatively shallow and narrow; esp. in fruits of Apiaceae (Umbelliferae). |
small-bristly |
= setulose |
pubescence |
|
Finely setose (hispid). |
chaff 1 |
|
STRUCTURE |
|
Collectively, the paleae (pales, palets) sometimes borne on the receptacle of a capitulum (head) in Asteraceae (Compositae). |
