Euphorbiaceae, Peraceae, Rafflesiaceae - Britannica
Euphorbiaceae (spurge family) now contains 218 genera and about 5,700 species, many of which are very poisonous. Peraceae includes five genera and 135 species. Members of Rafflesiaceae lack chlorophyll and are parasitic on other flowering plants.

2007年3月30日 · We present results of phylogenetic analyses of mitochondrial, nuclear, and plastid data showing that Rafflesiaceae are derived from within Euphorbiaceae, the spurge family. Most euphorbs produce minute flowers, suggesting that the enormous flowers of Rafflesiaceae evolved from ancestors with tiny flowers.

2017年5月29日 · Using a broad sample of Malpighiales, Rafflesiaceae were shown to fall within the spurge family, Euphorbiaceae, which contains the rubber tree, the castor bean, and cassava (Davis et al., 2007) (Fig. 1A). Euphorbiaceae is a highly diverse family and in its previously broad circumscription included members of Phyllanthaceae, Picrodendraceae ...

Euphorbiaceae lineages and crown-group Rafflesiaceae, but a different, higher rate to the stem lineage of Rafflesiaceae. This demonstrates that floral gigantism evolved principally along the stem lineage of Rafflesiaceae, whereas subsequent floral size evolution within crown-group Rafflesiaceae reverted to the original euphorbiaceous rate.
