PLÖNTUR SÚRUÆTTAR (Polygonaceae) eru jurtir, runnar og jafnvel tré. Stöngull er jarðlægur eða uppréttur, á stundum vafstöngull. Blöð eru dreifð, oftast stakstæð og heil, mjög sjaldan gagnstæð. Axlarblöð eru ummynduð í himnukennt, uppvítt axlarslíður (ochrea), sem lykur um stöngulinn og axlarbrumið (nema í Eriogonum).

Axlarslíður er eitt megineinkenni súruættar. Teikn. ÁHB.

Blómskipanir eru samsettar, ax- eða klasaleitar. Blóm eru regluleg, ein- eða tvíkynja, oft smá. Blómhlíf tví-, þrí- eða fimm-blaða; öll blómhlífarblöð oftast eins (tepals). Fræflar 3-9 (oft jafnmargir blómhlífarblöðum), í tveimur krönsum. Stílar 1-3. Aldin er flöt eða þrístrend hneta (hnot), oftast að mestu umlukt blómhlíf.

Til súruættar teljast 54 ættkvíslir og 1150 tegundir. Fæstar tegundir hafa verið nýttar. Bókhveiti (Fagopyrum) er mikið notað í stað korns, einkum í Kína og Japan, enda eru fræ í súruætt einkar sterkjurík. Blaðstilkar á rabarbara eru nýttir, blöð á súrum (Rumex) höfð í sallöt og á einni tegund (Coccoloba uvifera) myndast æt aldin. Margar tegundir ættarinnar teljast til illgresis. Allnokkrar tegundir eru ræktaðar sem skrautblóm og eru þær yfirleitt blaðstórar.

Nafnið Polygonaceae er dregið af Polygonum, sem merkir „með mörg hné“; úr grísku, polys, margur og goni, hné, enda eru margir stönglar liðskiptir.

Níu tegundir teljast til íslenzku flórunnar og skiptast þær á sex ættkvíslir. Um 12 slæðingar vaxa hér að auki.
