Phyllocladus alpinus

Phyllocladus alpinus, the mountain toatoa or mountain celery pine, is a species of conifer in the family Podocarpaceae. It is found only in New Zealand. The form of this plant ranges from a shrub to a small tree of up to seven metres in height.[1] This species is found in both the North and South Islands.[2] An example occurrence of P. alpinus is within the understory of beech/podocarp forests in the north part of South Island, New Zealand.[3]

The species contains the flavan-3-ols catechin, epicatechin and phylloflavan (ent-epicatechin-3-δ-(3,4-dihydroxyphenyl)-β-hydroxypentanoate).[4]
