To which taxonomic category do both Petroselinum and Phyllostachys belong?
Petroselinum Petroselinum (parsley) is a genus of two species of flowering plants in the family Apiaceae, native to western and southern Europe and northern Africa. They are bright green hairless biennial herbaceous plants, rarely annual plants. In the first year, they form a rosette of pinnate to tripinnate leaves and a tap root used as a food store over the winter. In the second year they grow a flowering stem up to 1 m tall with sparser leaves and umbels of white or pinkish to yellowish-green flowers.
Centroplacaceae Centroplacaceae is a family of flowering plants in the order Malpighiales and is recognized by the APG III system of classification. The family comprises two genera: "Bhesa", which was formerly recognized in the Celastraceae, and "Centroplacus", which was formerly recognized in the Euphorbiaceae, together comprising six species. The Angiosperm Phylogeny Group determined that based on previous phylogenetic analysis, these two genera formed an isolated clade and recognition of the family was "reasonable."
