This epiphytic member of the Rubiaceae family was described by Camilla Rose Huxley and Matthew H. P. Jebb in 1991. It is found in the jungles of Papua New Guinea. The hollow and smooth caudex gets 25 to 35 centimetres in diameter, the vines gets 60 centimetres long. The flowers are white on this ant plant, while the fruits are red.

The genera name from Green anthos; 'flower' and rhiza; 'root' for the root-derived spines around the flowers. The specific name from the Latin word bractea meaning 'scale' and the suffix -osa meaning 'having many'.

Only occasionally inhabited by ants, more usually by cockroaches, beetles and other invertebrates.
