Current conservation status
The threat classification status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2017 using the New Zealand Threat Classification System (NZTCS) – more information about this can be found on the NZTCS website This report includes a statistical summary and brief notes on changes since 2012 and replaces all previous NZTCS lists for vascular plants. Authors: By Peter J. de Lange, Jeremy R. Rolfe, John W. Barkla, Shannel P. Courtney, Paul D. Champion, Leon R. Perrie, Sarah M. Beadel, Kerry A. Ford, Ilse Breitwieser, Ines Schönberger, Rowan Hindmarsh-Walls, Peter B. Heenan and Kate Ladley. Please note, threat classifications are often suggested by authors when publications fall between NZTCS assessment periods – a suggested threat classification status has not been assessed by the NZTCS panel.

Distribution
Endemic. North Island, known from the eastern ranges. With certainty from the Raukumara and the Ruahine Range but it is probably elsewhere.
Habitat
Montane to subalpine. In shrubland and open ground.
Features
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.

Threats
Described in 1923, the species has always been considered uncommon. Very little is known about its exact status in the wild, and this is why it has been listed as Data Deficient.
Etymology
allanii: After Dr Harry Howard Barton Allan C.B.E. (1882–1957) one time school teacher, then first director of DSIR Botany Division, and ‘sole’ author of Flora I, the first in the former DSIR Botany Division flora series.
