A New Species of Etlingera (Zingiberaceae) From Bougainville Island, Papua New Guinea

Abstract

A new species, Etlingera frederikii, is described and illustrated, and is the first record of the genus in the Bougainville Region. Etlingera frederikii and E. cevuga, which occurs in Fiji and Samoa, are the two most easterly species in the distribution range of the genus. The new species differs from Etlingera cevuga in its much larger leaves, with a conspicuously silky-haired band on the ligule; the smaller, narrowly ovoid to cylindrical inflorescence with pale brown bracts (not hemiglobose with reddish brown bracts); and fewer, smaller flowers.

Short Communication: New insights into the morphology and distribution of the Philippine endemic Etlingera pilosa (Zingiberaceae)

“…Etlingera Giseke is a genus of the ginger family belonging to subfamily Alpinioideae, tribe Alpinieae, with about 150 species distributed from Bhutan to Fiji, most of which are occurring in equatorial Malesia (Poulsen & Bau 2017;Poulsen & Docot 2018). At present, Etlingera is represented in the Philippines with 17 species, 10 of which are endemic (Pelser et al 2011;Poulsen & Docot 2018;Naive et al 2020).…”
