Korthalsella salicornioides or dwarf mistletoe is an endemic parasitic plant in New Zealand. [2]

Contents

Description

Korthalsella salicornicoides is named after the succulent coastal plant Salicornia , because it has succulent stems. These appear as a dense mass of small fleshy leafless twigs, up to 10 centimetres (3.9 inches) long, usually growing on the host plants mānuka ( Leptospermum scoparium ) and kānuka ( Kunzea ericoides ). It is reddish-yellow to green with tiny flowers and small yellow fruits from October to May. [3] It is similar to the other two species of New Zealand leafless mistletoe in the genus Korthalsella , but has denser stems arising at a narrower angle.

Conservation

This species is scattered across forests and scrublands in New Zealand, only abundant in small local patches. [4] In some areas it is threatened by felling of Leptospermum and Kunzea for firewood, farming, or exotic forestry. [3] As at 2023, this species is classed as At Risk - Declining by the Department of Conservation. [1] This species is also regarded as "declining" in the Wellington Region as at December 2025. [5]
