Current conservation status
The conservation 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). 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.

Semi-parasitic shrub mainly on outer branches of beech trees. Obvious when in flower or from flowers fallen to ground. Leaves oval, dull green and with a reddish margin. Flowers tubular, orange-yellow, in small clusters.
North Island and South Island, New Zealand
Its host is most commonly mountain or black beech but it has been recorded on 13 species, all indigenous to New Zealand. In North Island the species is dispersed by bellbird (Anthonis melanura). It has never been common in the North Island.
This species is a shrub that can grow up to 2 m across. It has leathery leaves that are 2-6cm long, narrow and dull green with deciduous tip. The leaves sit in pairs on opposite sides of the stem and are thick and fleshy with a matt surface. The margins of the leaves are red and are rough to touch. Veins are visible on the lower surface of the leaves. Its flowers are small with orange-yellow to yellow tepals that open right back. The fruit are small, shiny, translucent oval berries (approximately 4-5mm long) and ripen to yellow or gold although fruit have been recorded as yellow, green and orange on herbarium sheets at the Landcare herbarium in Lincoln (CHR).
Peraxilla colensoi, P. tetrapetala. Alepis flavida has disc-like attachment structures and oblong leaves with red margins. The plant grows in the outer branches of its host. Peraxilla colensoi and P. tetrapetala are more leafy, have red flowers, round or diamond-shaped leaves with no red margin. They have different attachment structures and usually grow on the trunks of the host tree.

Fruiting from January.
Fleshy berries dispersed by fruigivory (Thorsen et al., 2009).
