The the perianth
segments are fused towards the bases and free towards the tips, they are 3 mm in width and 2.
Record of Dolichotetranychus vandergooti (Oudemans) (Acarina: Tenuipalpidae), a perianth
mite on Coconut.
In contrast, in monosymmetric flowers that have a vertical upright position, monosymmetry is often only expressed in the perianth
Evolution of perianth
and stamen characteristics with respect to floral symmetry in Ranunculales.
In Musaceae, the basal-most member of the order, five of the six perianth
members fuse to form a floral tube (Figs.
In species that show wilting of the perianth
, an important function of senescence may be to allow remobilization of key metabolites from the senescing organs back into the plant.
The fins (or wings) may be derived from ovary outgrowth, perianth
, hypanthium, or bract elaboration.
part connation: floral parts flee=0; floral parts fused= 1.
palustris have a reduced number of perianth
parts and a dimerous gynoecium.
2006) have revealed an adaxially situated third scale in some proximal flowers in spikelets of Hellmuthia, and these are interpreted to be perianth
segments and not glumes of reduced florets as in Mapanioideae.
In addition, plants of this family can be easily identified by their lenticels on the trunk and branches, aromatic bark and leaves with peppery taste, simple and alternate-distichous leaves, flowers with fleshy perianth
, three sepals (rarely two) and berry fruit containing reniform seeds (Salazar, 20O6).
In contrast to the male flowers, the female perianth
is not at all recognizable as tepals, consisting of a thin undivided layer adhering to the ovary (this unusual anatomical feature is very important ecologically as discussed in the "Evolution of Propagules Under Domestication" section, and for classification purposes, as discussed in the "Classification and Nomenclatural Issues" section).
