Chamaesyce - local euphorb

EUPHORBIACEAE, Malpighiales Cymothoë likes Malpighiales, its allies are all Rosid specialists and mostly eurosids I specialists.

Achariaceae CARYOCARACEAE – prominent trees in the tropics Ctenolophonaceae EUPHORBIACEAE – GENTRY FAMILY Goupiaceae Humiriaceae Irvingiaceae Ixonanthaceae Lacistemataceae LINACEAE – flax family Lophopixidaceae Pandaceae PHYLLANTHACEAE – formerly part of Euphorbiaceae Picrodendraceae Putranjivaceae RAFFLESIACEAE- parasites including largest flower SALICACEAE – GENTRY FAMILY VIOLACEAE-violets and tropical treelets
