“…Kiamo, locality Bukidnon, at elevations from 1,000 to 1,400 m asl. The species is unique among the other Etlingera species by the presence of raised stilt roots, fusiform inflorescence, peduncle which is not embedded in the ground, and papery sterile and fertile bracts (NAIVE et al, 2020). This species was also collected and reported in 2018 at Mt.…”

The ginger species (Zingiberaceae family) have attract a lot of scientific attention because of their perceived beneficial effects on health. Despite this, for the numerous species of the family, scientific reports are quite scarce and warrant further analyses. The most of until now analyzed ginger species are allochthonous in the Philippines. Thus, this study was carried out to determine the total phenolic content and antioxidant activity of the ethanolic extracts of the leaves and rhizomes of Etlingera dostseiana Naive, Demayo & Alejandro, a Philippine endemic ginger species. Data recorded for total phenolic content (mg GAE/g dried sample) revealed that the leaves (15.44 ± 0.80) have a greater amount of phenolics than the rhizomes (0.59 ± 0.03). The total antioxidant activity (mg AAE/g dried sample) was also observed to be higher in leaves (14.24 ± 0.25) than in the rhizomes (0.91 ± 0.04), as well as the reducing power (mg GRPE/g dried sample) - 10.33 ± 1.13 in leaves versus 0.21 ± 0.06 in rhizomes. Based on the correlation analysis, a perfect positive linear relationship was observed among the total phenolic content, total antioxidant activity, and reducing power (r=1, p<0.001). These imply that the high contents of phenolic compounds contribute to the antioxidant activity of extracts of E. dostseiana. It can be regarded that E. dostseiana could be a candidate as a natural plant source of antioxidant compounds.

“…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). The genus is less explored in the Philippines, most specifically in the island of Mindanao, but future fieldwork would probably result in the discovery of more species either endemic or as new records from neighboring countries.…”

Abstract. Naive MAK, Demayo CG, Alejandro GJD. 2021. Short Communication: New insights into the morphology and distribution of the Philippine endemic Etlingera pilosa (Zingiberaceae). Biodiversitas 22: 3175-3179. Etlingera pilosa Poulsen & Docot, only known in Negros Oriental and Negros Occidental of Visayas islands, Philippines, is recorded in the island of Mindanao for the first time, thus, extending its distributional range. The species is characterized by having sericeous ligule; leaves subsessile, narrowly obovate, coriaceous, glabrous adaxially, densely pubescent abaxially; inflorescence up to 12 cm long; flowers yellow, 3.0–3.2 cm long; subglobose to obovoid, pilose, with wart like blunt spines fruit; and seeds irregularly subglobose to oblate, black, fully embedded in juicy sour-sweet white aril. This species closely resembles E. pubimarginata but differs in having densely pubescent abaxial leaf, sericeous ligule and subglobose to obovoid, pilose, with wart like blunt spines fruit. Here, we provide a detailed description, comparison with its allied species, colored photographs to aid identification, a distribution map, an IUCN conservation assessment and a taxonomic key to the Mindanao Etlingera species.
