Simplified description
Flattened beaded succulent very small (to 8 cm) shrub growing on twigs of another plant. Leaves (flattened stems) 5–10 mm long by 1.5–3.5 mm wide, widest towards tip. Flowers tiny, fruit small, green, on short spike.
Flower colours

Distribution
Endemic. New Zealand: North Island (from near Whakamaru south to Wairarapa and Turakirae Head), South Island (throughout, though notably more common in the east).
Habitat
Coastal to subalpine. Usually found parasitising shrubs within grey scrub communities, also found on shrubs and trees within montane alluvial forest. No clear host preference is as yet evident, though regional patterns may exist (this needs study).
Current conservation status
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2022-2023 using the New Zealand Threat Classification System (NZTCS) – more information about this can be found on the NZTCS website. This report includes replaces all previous NZTCS lists for vascular plants. Previous assessments can be found here.
Please note, threat classifications are often suggested by authors when publications fall between NZTCS assessment periods – these interim threat classification statuses has not been assessed by the NZTCS panel.
