Of the 250 or so species of Grevillea, a small number of these species (within a specific section of the genus) and their associated hybrids have been recorded as causing contact dermatitis. A brief historical survey of the occurrence of contact dermatitis and the species responsible is given. Attention is drawn to the associated species, about which at the present time no information is available regarding their possible effect on man. Because one of the hybrids, G.x "Robyn Gordon" is an extremely popular garden plant which has been widely planted in various sites, attention is drawn to the likely trouble it may cause to those who come into actual contact with it.
