GUNNERA L., 1767

Infl. paniculate to scapose; fls unisexual or perfect. Sepals and petals 2-3 or 0; stamens 1-2; ovary inferior, 1-celled, 1-ovuled; stigmas 2; fr. a drupe. Perennial herbs with radical lvs, extremely large to small, bearing intravaginal scales. Some 40 spp., mainly of S. America, S. Africa, East Indies, New Guinea.
The N.Z. spp. are endemic, but closely allied to the Tasmanian. But little progress has been made since the revision by Kirk (T.N.Z.I. 27, 1895, 341-348) and the group needs study de novo.
