heterogamous |
|
reproduction |
plant, inflorescence |
Having flowers that differ distinctly in size, shape and/or constitution. |
|
receptacular |
|
position |
|
Upon, arising from, or otherwise directly associated with the receptacle. |
|
second glume |
|
STRUCTURE |
|
The upper (distal) member of a pair of small bracts inserted at the base of a grass (Poaceae) spikelet. |
|
involucrate 1 |
|
architecture |
inflorescence |
Subtended by an involucre. |
|
chaff 2 |
|
STRUCTURE |
|
Collectively, the glumes, lemmata, and paleae of mature spikelets; in Poaceae (Gramineae). |
|
infrapetiolar |
|
insertion |
bud |
Axillary and surrounded by the petiole base at maturity. |
|
sheathing 2 |
|
base |
laminar structure |
Terete or involute and closely enclosing the supporting axis for some distance above the point of insertion. |
|
antisepalous |
|
insertion |
equivalent floral structures |
Each inserted directly above or below a sepal. In place of this term, the phrase "opposite the sepals" is often used, but that contradicts the sense of opposite as otherwise employed (arrangement of lateral structures along an axis) and should be avoided. |
|
coetaneous |
|
maturation |
dissimilar structures |
Maturing concurrently. This adjective is frequently used to mean contemporary maturation of leaves and flowers, but without actually stipulating that those are the structures involved. Such usage is erroneous according to the construction and literal meaning of the term, which properly applies to structures, not to the taxon or plant. See also synanthous. |
|
corymbose |
|
architecture |
inflorescence |
Comprising one or more corymbs. |
|
linear 2 |
|
plane shape |
|
Elongate and narrow with the sides more or less straight and parallel over most of its length. |
|
stephanoporate |
|
architecture |
pollen grain |
Having more than three pores disposed equatorially. |
|
mesochilium |
|
STRUCTURE |
|
The central portion of a labellum (lip) that has distinct proximal, distal, and central parts; in Orchidaceae. See also epichilium, hypochilium. |
|
actinocytic |
|
architecture |
stomate |
Having several subsidiary cells oriented radially to its center. |
|
neck (floral tube) |
|
STRUCTURE |
|
The solid, usually constricted portion of a floral tube sometimes present between casing and collar when those are both present. |
|
deltate |
|
plane shape |
|
Equilaterally triangular, broadest at the base, and regularly attenuate to an angular apex. See also obdeltate. |
|
superaxillary |
|
insertion |
|
Internodal but close to and directly above the axil(s). |
|
elliptic(al) 1 |
|
arrangement |
bundle scars |
Forming an ellipse |
|
…faced |
|
solid shape |
|
Having relatively large, flat or shallowly curved portions of the external surface that are bounded by more or less distinct angular discontinuities in that surface, of the number indicated by the prefix; as in three-faced. |
|
parasitic |
|
nutrition |
plant |
Heterotrophic and obtaining essential nourishment directly from other living organisms that derive no reciprocal benefit. |
|
flush |
|
prominence |
|
Even with the surrounding surface, neither higher nor lower than its general level. |
|
flanged |
|
plane shape |
|
Having a relatively broad circumferential rim or ridge that protrudes laterally. |
|
amphimictic |
|
reproduction |
taxon, plant |
Reproducing sexually. |
|

|
insertion |
|
Upon or otherwise directly associated with the prophylls (bracteoles, bractlets). |
|
villosulous |
|
pubescence |
|
Finely villose (shaggy, villous). |
