Illustrations, maps and preliminary conservation assessments are provided for all the species.

A molecular phylogeny of Southeast Asian Cyrtandra (Gesneriaceae) supports an emerging paradigm for Malesian plant biogeography

“…For monophyletic species with multi-island distributions, such as C. umbellifera from Taiwan and the Philippines and C. sandei from Java and Sumatra, only one sample was included, and these were coded as present in each respective area in the analysis. Each taxon was assigned a distribution using 13 geographic regions based on a combination of geological information (Hall 2002(Hall , 2012, previous biogeographical studies , van Welzen et al 2011 and current knowledge of species distributions and relationships in Cyrtandra , Bramley and Cronk 2003, Johnson et al 2017, Kartonegoro et al 2018. The 13 regions used were: Hawaii, Marquesas and Society Islands, Japan and Taiwan, Australia, Thailand, Peninsular Malaysia, Sumatra, Borneo, Sulawesi, New Guinea, Solomon Islands, Java and the Lesser Sunda Islands, and the Philippines.…”

Cyrtandra argentii, a new species of Cyrtandra (Gesneriaceae) from the Philippines, and a review of the C. villosissima group

“…Herbaria acronyms follow Index Herbariorum (Thiers, continuously updated). Descriptions follow schemes of recently published accounts of new species Johnson 2017;Kartonegoro et al 2018;Atkins et al 2019). Assessment of Conservation Status was implemented using GeoCAT (Bachman et al 2011), following the IUCN Red List Category criteria (IUCN Standards and Petitions Subcommittee 2017).…”

“…The genus is recognized by possessing two fertile stamens and fruits that are indehiscent, either hard capsules or fleshy berries (Cronk et al 2005;Atkins et al 2013). Members of the genus exhibit diverse growth forms, ranging from herbs and shrubs, to climbers and small trees distributed throughout the Malesian region and across the Pacific (Johnson et al 2017;Kartonegoro et al 2018). Species of Cyrtandra are important rainforest elements, thriving in habitats with high humidity, low light intensity, and constant moisture supply (Gillett 1967).…”

“…In recent years, several studies (Wagner et al 2001;Bramley et al 2003;Atkins 2004;Bramley 2005;Lorence & Perlman 2007;Bone & Atkins 2013;Johnson 2017;Kartonegoro et al 2018;Atkins et al 2019;Nishii et al 2019) have led to an increase in numbers of species of Cyrtandra. These studies emphasized the urgency to document and understand the biodiversity of cyrtandras before they succumb to anthropogenic pressures.…”

Floristics of forests across low nutrient soils in Sulawesi, Indonesia

“…Discovery of the “peculiar,” “beautiful,” and “unique” flora continues (Brambach, Coode, Biagioni, & Culmsee, 2016; Bramley, 2012; Cámara‐Leret & Veldkamp, 2011; Kartonegoro, Bone, & Atkins, 2018; Low, 2013; Rugayah & Sunarti, 2017; Rustiami & Henderson, 2017). Knowledge of floristics across much of the island is still lacking, however, with low density of botanical collections and forest monitoring plots (Brearley et al, 2019; Kessler et al, 2002).…”
