Qld: near Atherton, E.Volck & S.Dansie 1471 (BRI, NSW); Wongabel, L.S.Smith 10175 (BRI, NSW); Mowbray R., L.J.Brass 1981 (A, B, BRI). N.S.W.: Nimbiro, near Lismore, Sept. 1925, E.Cheel (NSW); Tweed R., W.Bäuerlen, NSW 77926 (NSW).

Perhaps the most virulent stinger in the genus and much feared by susceptible foresters in the field. The species is unique in the genus in having bisexual inflorescences in which the few male flowers are surrounded by female flowers in each floral fascicle.
