Malpighiales
From eagle-rock.org
Malpighiales is one of the largest orders of flowering plants, containing about 16000 species. The order is very diverse and hard to recognize. It is not part of any of the classification systems that are based only on plant morphology. Molecular clock calculations estimate the origin of stem group Malpighiales at around 100 Mya (million years ago) and the origin of crown group Malpighiales at about 90 Mya.
Malpighiales is divided into 32 to 42 families. The largest family, by far, is Euphorbiaceae, with about 6300 species in about 245 genera. See Malpighiales - Wikipedia
