... The Ericaceae of Sulawesi have been treated in Flora Malesiana (Sleumer 1964(Sleumer , 1966(Sleumer -1967 but many new taxa have been subsequently described (e.g. Argent 2009Argent , 2014Craven 2014;Argent & Widjaja 2015;Argent & Mambrasar 2019;Mustaqim & Ardi 2019, 2021Hutabarat et al. 2022).

(Chase et al. 2016;Argent 2019;Kron et al. 2020;Mustaqim & Ardi 2021). ...

... Herbarium specimens were examined from A, BRIT, CAS, CMUH, NY, PNH, UC, and US, including digitized specimens at BISH, BM, CANB, E, HBG, K, L, MICH, and U [herbarium acronyms follow Thiers (2022), continuously updated] available online at JSTOR Global Plants (https://plants.jstor.org). Characters in descriptions were defined as in Beentje (2016), and relevant taxonomic literature on Philippine and Malesian Vaccinium was consulted (i.e., Copeland 1930;Sleumer 1966Sleumer -1967Veldkamp 1979;Co et al. 2002;Argent 2008Argent , 2014Salares et al. 2018;Argent 2019;Mustaqim & Ardi 2019;Argent & Wilkie 2020;Fritsch et al. 2020;Tamayo et al. 2021;Mustaqim et al. 2022;Tamayo et al. 2022;Tamayo & Fritsch 2022a, b;Tamayo et al. 2023). The area of occupancy (AOO) and extent of occurrence (EOO) of the three species were obtained with the use of GeoCAT (Bachman et al. 2011). ...

... The absence of glands on the leaf blade base of Malesian Vaccinium species is unusual, but it has been documented in the two Sumatran species, V. bartlettii Merrill and V. nagamasu Argent (Sleumer, 1966(Sleumer, -1967Argent, 2011). Vaccinium maliauense can be distinguished from V. bartlettii by having larger leaf blades (3.5-4.2 × 2-3 cm vs. 0.7-1.2 ...

... Diplycosia Blume (Ericaceae: Vaccinioideae: Gaultherieae) comprises about 116 species distributed throughout Southeast Asia and New Guinea (Sleumer 1967;Argent 1982Argent , 1989Argent , 2002Ferreras and Argent 2011;Argent 2013Argent , 2014Fritsch and Amoroso in press;Fritsch and Bush in press). The genus can be delimited from other genera of the tribe by a base chromosome number of x = 18 (vs 11), and a combination of (usually) entire leaf margins, fasciculate inflorescences, paired bracteoles borne at the apex of the pedicel, anthers with terminal tubules but with neither spurs nor disintegration tissue, and a capsule surrounded by an accrescent, fleshy calyx, or rarely a berry. ...
