A new species of Artemisia L. Sect. Artemisia (Asteraceae) from Manipur state, North East India

A new species of Artemisia kangleipaken-
sis sp. nov. is collected from the forests of Ukhrul dis-
trict, Manipur state, India. The collected new species
is described based on the distinct morphological char-
acters such as capitula with distinct stalks, involucre
and phyllaries linear or oblong, and florets less than
14 compared to the closely allied species Artemisia
indica Willd. Based on the morphological features,
the systematic position of the species is assigned
to the Artemisia Sect. Artemisia. Furthermore, its phylogenetic placement is determined through molec-
ular research using nuclear ribosomal DNA internal
transcribed spacer (ITS). Santolina triene is proposed
as a potential chemotaxonomic marker because it is
the dominant monoterpene compound in its fresh
leaves analysed through headspace-solid phase micro-
extraction gas chromatography–mass spectrometry
volatiles profiling. Additionally, the micromorphol-
ogy of achene and foliar trichomes was investigated.
The new species is characterized by macro and
micromorphology, chemotaxonomy and molecular
phylogenetic approaches. The diagnosis, description,
distribution map, and taxonomic description of the
new species are provided.
