overlapping 1 |
= imbricate(d) |
aestivation |
|
Having members whorled or spirally inserted and overlapping one another, each overlapping or overlapped to either side, and also above or below if spirally arranged or in multiple whorls. |
|
impressed |
< sunken |
prominence |
|
Shallowly sunken. |

prominent |
< raised |
prominence |
|
Protruding above the general level of the surrounding surface. See also prominulous. |
|
bulliform |

|
Resembling a blister; broad, relatively thin at the periphery, the lower surface approximately flat, the upper shallowly to strongly convex. |
|
echinate |
= spinose, spiny |
architecture |
|
Bearing spines. |
|
macrosporocarp (not recommended) |
= megasporocarp |
STRUCTURE |
|
A sporocarp that bears only macrosporangia (megasporangia). |
|
umbo pl. umbines, umbos |
|
FEATURE |
|
A relatively small, rounded or conical, central protrusion upon an essentially round, broad face. |
|
fruit |
|
STRUCTURE |
|
Any unitary seed-bearing structure of a flowering plant, consisting of the matured or ripened pistil(s) of one or more flowers along with any other floral or vegetative tissue(s) persisting adnate to them; characteristic of and unique to Magnoliophyta (Angiospermae). |
|
apex pl. apices |
|
CHARACTER |
|
Configuration of the uppermost, distal, or terminal portion of a structure, its extent determined somewhat subjectively in relation to the shape of the structure as a whole. The concept of apex varies from one descriptive context to another, since the apex is not a clearly delimited, morphologically distinct entity. The terms for describing apical condition are not strictly coordinate logically — some are more inclusive than others, some describe conditions involving what can be regarded as appendages, and some refer to the apex in a developmental as well as a strictly topological sense — and precise characterization may require using more than one descriptor. The semantic antecedent of some descriptors is "apex," whereas the antecedent of others is the structure as a whole (e.g., leaf ). |
|
carpophore 1 |
< stalk |
STRUCTURE |
|
The stalk supporting a sporocarp. |
|
auriform |
= ear-shaped |
solid shape |
|
Resembling a mammalian outer ear. |
|
knotty |
= knobby, nodose |
solid shape |
|
Having knot-shaped (gongylodate, gongyloid, knob-shaped, nodiform) protrusions. See also nodulose. |
|
ala 1 pl. alae |
= wing |
STRUCTURE |
|
Any elongate, relatively thin protrusion or appendage. |
|
ray floret |
|
STRUCTURE |
|
A floret that has a zygomorphic corolla, is pistillate (either fertile or sterile) or neuter, and is borne in a radiate capitulum (head) peripheral (proximal) to the disc florets; in Asteraceae (Compositae). |
|
extrafloral |
|
insertion |
|
Outside and proximal to the flower; esp. nectaries. |
|
watery |
|
texture |
|
Liquid and weakly cohesive, flowing freely; like water. This term often implies also transparency. |
|
gynophore |
= hypogynium; < stalk, stipe (broad sense, not recommended) |
STRUCTURE |
|
The basal portion of an ovary when constricted and stalk-like above the level of perianth insertion, bearing the main body of the pistil at its summit. |
|
spore |
|
STRUCTURE |
|
A simple, usually unicellular, sometimes oligocellular propagule derived by meiotic division of a diploid (2n chromosomes) sporocyte within a sporangium, thus of haploid (n chromosomes) genetic constitution. A spore constitutes the first ontogenetic stage of a gametophytic generation and gives rise to a usually multicellular gametophyte upon germination. Though technically present in seed-bearing plants, by itself it is descriptively significant only in those taxa that do not produce seeds. |
|
coccus pl. cocci |
= mericarp |
STRUCTURE |
|
One of the segments of a dehisced schizocarp; usually one-seeded and itself indehiscent. |
|
bracteolate |
= bractleted |
architecture |
|
Bearing or subtended by one or more bracteoles (bractlets, prophylls). |
|
lip cell |
|
STRUCTURE |
|
Either of a pair of adjacent, narrow, transversely oriented, thick-walled cells bordering the pore (stomium) of a sporangium. |
|
tuberculate |
= tuberculose, verrucose, warty |
relief |
|
Covered with small, relatively broad, irregularly shaped, obtuse protrusions. |
|
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. |
|
campanulate |
= bell-shaped |
solid shape |
|
Circular in transverse section, inflated proximally, thence broadening gradually to a flared distal portion. |
