Schizeilema allanii Petrie nom. illeg.; Schizeilema allanii Cheeseman


Endemic. North Island, known from the eastern ranges. With certainty from the Raukumara and the Ruahine Range but it is probably elsewhere.


Montane to subalpine. In shrubland and open ground.


Hairless creeping herb forming diffuse patches up to 30 cm diameter. Stems creeping, branched, rooting freely at nodes. Leaves confined to nodes. Leaf stalks slender 5-10(-15) cm long. Leaves 2-3 cm diameter, pale green, somewhat leathery, deeply 3-lobed or completely trifoliolate, lobes obcuneate, margins only very slightly thickened or recurved and irregularly lobed or crenulate (like a pie crust) towards apex. Inflorescence an umbel 15 mm diameter, borne on slender, 10 cm long, occasionally branched stalk (peduncle). Flowers 8-12 on unequal pedicels 5-10 mm long, subtending floral bracts (involucral bracts) linear acute to acuminate. Fruit 2.5 mm long, 4-angled, deeply furrowed, mericarps distinctly to obscurely 5-ribbed.

Similar Taxa

Closest to Schizeilema colensoi but distinguished from that species by the leaf margins being scarcely recurved or thickened, and by the pedicels being > 3 time the length of the fruit.
