PLANTAE TRACHEOPHYTA MAGNOLIOPSIDA SCROPHULARIALES ACANTHACEAE

Scientific Name: Acanthus ilicifolius
Species Authority: L.
Common Name(s):
English Holy Mangrove
Taxonomic Notes: Three species of Acanthus were recorded in the mangroves of South China, including Acanthus ebracteatus Vahl, Acanthus ebracteatus var. xiamenensis (R.T.Zhang) C.Y.Wu & C.C.Hu (Deng et al. 2006.) and Acanthus ilicifolius L. However, Acanthus ebracteatus var. xiamenensis has been combined with Acanthus ilicifolius in 2008 (Hou and Lu 2008). Only Acanthus ilicifolius is recorded in the Pearl River Region.
