Barrett, R.L. & Lowrie, A. Typification and application of names in Drosera section Arachnopus
(Droseraceae). Nuytsia 23: 527–541 (2013). Taxonomic review of the Drosera indica L. (Droseraceae)
complex requires the clarification of a number of published names. This paper is focussed on the
application of names applying to taxa occurring in Australia. Two lectotypes are chosen and one
neotype is designated for names historically listed as synonyms of D. indica. Drosera serpens Planch.
and D. angustifolia F.Muell. are lectotypified. A neotype is selected for D. hexagynia Blanco as no
original material is known. Drosera hexagynia is considered to be a synonym of D. indica. Drosera
angustifolia and Drosera indica f. robusta F.M.Bailey are here considered to be synonyms of D. finlaysoniana
Wall. ex. Arn. Drosera angustifolia var. purpuriflora F.Muell. ex Diels is an illegitimate name. Notes
are provided on D. hartmeyerorum Schlauer, the only other named Australian taxon in this species
complex. Characteristics of the seeds, anthers and glandular hairs are considered diagnostic at the
species level. Illustrations of key identifying features and full descriptions of the Australian species
are provided.
