'Flower types' provides explanatory diagrams of the more unusual types of flower such as the daisies, peas, and orchids, as well as for the terms actinomorphic and zygomorphic
, which relate to floral structure.
The habit of these species is very peculiar because of their adaptations to the parasitic lifestyle, including greatly reduced, achlorophyllous, vegetative organs, and colorful dense inflorescences with zygomorphic
flowers on fleshy stems (Piwowarczyk et al.
. The calculated result is smaller at the left end and larger at the right end because surface effect increases the efficiency of stress transfer with increasing normal stress.
Leaves with exactly 4 pairs of leaflets; nectary located on the petiole; flowers zygomorphic
dots or stripes on corolla); (vi) floral symmetry (actinomorphic or zygomorphic
); (vii) stamen number (two, four or five); (viii) anther position (determined by the anther location relative to the corolla tube, i.e.
or pinkish type flowers with white with inflorescence terminal panicle, up to 18 cm long, fulvous pubescent and small fruits enclosed in red bracts.
Floral anatomy and systematics of Alliaceae with particular reference to Gilliesia, a presumed insect mimic with strongly zygomorphic
Lithophytic rosulated, cespitose herbs to 1.7 m high, with conspicuous slender stolons, the mature rosettes zygomorphic
; leaves 15-20 per rosette, sheaths white, lustrous on both surfaces, blades light green with purple marginal bands, narrowly triangular, densely lepidote abaxially; inflorescence lateral, erect; peduncle bracts foliaceous, 2-20 cm long, linear, attenuate and pungent, spiny at the margins; staminate inflorescences twice branched; pistillate inflorescences once branched; staminate flowers white, sessile; filaments in the male flowers 3.9-4.2 mm long, anthers yellow, 2-2.5 mm long, with a conspicuous apical acumen; pistillate flowers greenish white, sessile; sepals 3.5-4.3 mm long; petals narrowly triangular elliptic, 5.8-6 mm long.
Among the zygomorphic
flowers (21.7%), the flag was the principal type.
An object having exactly one line of symmetry can be termed as zygomorphic
. Our brain can be classified as a zygomorphic
object, since it is symmetric along a line, drawn vertically on the image.
Sesame has zygomorphic
flowers with pendulous tubular corolla of 3-4 mm in length and coloring of various shades of purple white.
