Hoplophyllum spinosum
Hoplophyllum ferox

Hoplophyllum is a genus of flowering plants in the family Asteraceae. [1] It has two species, Hoplophyllum spinosum and Hoplophyllum ferox, both native to South Africa. [2]

Both species are shrubs. The leaves are hard and spine-tipped, much longer than wide, and either cylindrical or somewhat flattened. They are grooved with stripes running lengthwise. The type species is Hoplophyllum spinosum. [3]

Hoplophyllum is derived from two Greek words, hoplon "a tool or weapon" and phyllon "a leaf", a reference to the spiny leaves. [4]

The name Hoplophyllum was originated in 1836 by A.P. de Candolle [5] when he assigned Hoplophyllum spinosum to this genus in his classic work Prodromus Systematis Naturalis Regni Vegetabilis. [6] This species had originally been named Pteronia spinosa by Linnaeus filius in 1782 in his book Supplementum Plantarum. [7]

The closest relative of Hoplophyllum is Eremothamnus, another native of southern Africa. [8] In one classification, published in 2009, these two formed the tribe Eremothamneae. [9] Other authors have placed them in the tribe Arctotideae. [1]
