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.
