Kirk's description is: "Rhizomes slender; leaves 11/2 in.-21/2 in. long, with weak scattered hairs on petiole and blade; blade ovate or slightly cordate, rounded at the apex, crenate but not lobed. Scape very slender, unbranched, exceeding the leaves; upper flowers lax, sessile or shortly pedicelled; staminate, pistillate, and hermaphrodite flowers intermixed, staminate mostly pedicellate; perianth segments 2, narrow linear-oblong, obtuse; female perianth segments 4, ovate, unequal, sometimes with two linear-oblong processes springing from the base of the segment; hermaphrodite flowers with ovate segments alternating with two linear-oblong; filaments short, anthers apparently abortive. Fruit not seen . . . simple, lax, subracemose scape exceeding the leaves, which distinguishes it from all other species." Kirk had material from Otago, collected by J. Buchanan and A. Hamilton.
Stolons rather stout, up to ± 4 dm. long; lvs on petioles (15)-20-70-(80) mm. long, canaliculate, strigose-hairy. Lamina subcoriac., dull green, cordate-orbicular to reniform, 10-25 × 7-25 mm., sts more, crenately 5-8-(11)-lobed; lobes themselves crenate; surfaces strigose-hairy especially on veins. ♂ part of infl. branched below and sts above; fls subsessile, bracts minute, acuminate; calyx lobes ovate-acuminate, 1·5 mm. long, tube obsolete, staminal filaments c. 3 mm. long. ♀ part compactly branched. Drupe globose to ovoid, bright red ± 2.5 mm. long.
Stolons up to ± 4 mm. diam. Petioles up to 10 cm. (sts more) long, canaliculate, ± strigose-hairy. Lamina dark-green, at first sparsely hairy, cordate-reniform to suborbicular; sts truncate or cuneately narrowed to base (on same plant); 10-15-(20) × 15-18-(25) mm., occ. more; subcoriac.; lobes 3-5-(7); margins coarsely crenate to dentate-apiculate (on same lf). Infl. paniculate, us. much-branched, up to ± 15 cm. long, sts reduced. Fls as in G. monoica, ♀ compacted, style ± 4 mm. Drupes subglobose to subovoid, white, compacted, ± 2.5 mm. long.

Gunnera monoica Raoul

Stolons rather slender, up to ± 3 mm. diam., rosettes crowded to rather distant; lvs with slender appressed-hairy petioles up to 4 cm. or more long. Lamina rather dark clear green, reniform to suborbicular, cordate to cuneately narrowed at base, ± 10-12 × 12-15 mm. or more, subcoriac., with scattered hairs; lobes 3-5-(7) often obscure; teeth dentate-serrate, sts apiculate, irregular. Infl. up to c. 7 cm. long; ♂ ± sessile, lax; bracts ± 3 × 2 mm., ovate, laciniate; calyx-lobes ovate-acuminate; petals clawed; stamens pubescent, filaments ± 3 mm. long. ♀ on lower branches, very shortly pedicelled; tube of calyx ellipsoid, lobes acuminate, petals 0, styles 2-3 mm. long. Some perfect fls may be present. Drupes aggregated, subglobose, white, up to ± 2 mm. diam.

Gunnera monoica Raoul

Monoecious herb. Lvs (1)-2-6-(9) cm long; lamina very variable in shape, usually broadly ovate or orbicular, shallowly to deeply cordate, not lobed or shallowly to deeply lobed, coarsely dentate or crenate, subcoriaceous, usually hairy. Infl. with ♂ fls above ♀. Infructescence usually hidden among lvs, sometimes partly exposed. Drupes spaced along stalk or clustered, barrel-shaped, white, often flecked with purple or red, or very rarely (probably hybrids) entirely orange or red; seed free within fleshy envelope.
