Polygonales
Polygonales was an order of flowering plants recognized by several older systems such as the Wettstein system, last revised in 1935, the Engler system, in its update of 1964, and the Cronquist system, 1981. Its circumscription was typically:

or
Polygonineae (depending on whether they are considered an order or a suborder of Caryophyllales). The Caryophyllineae is sometimes called "core Caryophyllales" and the Polygonineae is sometimes called the "non-core Caryophyllales".
The core Caryophyllineae sub-order is well-supported with numerous distinctive synapomorphies,
such as: 1) sieve tubes of phloem with plastids with peripheral ring of proteinaceous filaments (often with a central protein crystal), 2) presence of
betalains
Betalains are a class of red and yellow tyrosine-derived pigments found in plants of the order Caryophyllales, where they replace anthocyanin pigments. Betalains also occur in some higher order fungi. They are most often noticeable in the petals o ...
, 3) loss of the rpl2 intron in cpDNA, 4) single whorl of
tepals
A tepal is one of the outer parts of a flower (collectively the perianth). The term is used when these parts cannot easily be classified as either sepals or petals. This may be because the parts of the perianth are undifferentiated (i.e. of very ...

embryo, and 7) presence of
perisperm
In seed plants, the ovule is the structure that gives rise to and contains the female reproductive cells. It consists of three parts: the ''integument'', forming its outer layer, the ''nucellus'' (or remnant of the megasporangium), and the fe ...
