Abrotanella linearis is a species of flowering plant in the daisy family (Asteraceae) and is native to Stewart Island and the South Island of New Zealand.[2] Swedish botanist Sven Berggren described the species in 1878. Plants of this species are small with linear leaves and white florets.
Taxonomy
Abrotanella linearis Berggr. is a plant endemic to New Zealand in the family Asteraceae.[3] It was described in 1878 by Swedish botanist Sven Berggren.[4]
The type material was collected by Berggren at Kelly's Hill in Westland, New Zealand.[4] The lectotype was designated by Ulf Swenson and is held at the Lund University herbarium (Herbarium LD), with isolectotypes at other herbaria.[4]
The specific epithet, linearis, refers to the linear shape of the leaves.
The chromosome number is 2n=18.[5][6]
Phylogeny
Abrotanella linearis was included in phylogenetic analyses of standard DNA sequencing markers (nuclear ribosomal DNA and chloroplast DNA regions).[7] It was placed within a monophyletic Abrotanella genus in a highly-supported clade comprising species from New Zealand, Australia and New Guinea.[7]
Distribution and habitat
Abrotanella linearis is endemic to New Zealand.[3] It is common in montane forest and subalpine grasslands from 700-1400 m above sea level on the South Island, and from 250-670 m on Stewart Island. It flowers from September to February.[4]
Conservation status
A. linearis was listed as Not Threatened on the most recent assessment (2023-2024) of the New Zealand Threatened Classification for plants.[1]
