Abstract
One genus (Anoectochilus) and 12 species (Agrostophyllum neoguineense, Anoectochilus papuanus, Arundina graminifolia, Bulbophyllum aemulum, B. bisepalum, B. nubigenum, B. ochroleucum, B. phreatiopse, Corybas solomonensis, Crepidium laevis, Didymoplexis striata, Epipogium roseum) of orchids (Orchidaceae) are first recorded to the flora of the Solomon Islands during the 2012-2015 field expeditions. Geographic data, ecological and taxonomic notes and illustrations of those species are provided. A new combination (Pinalia oligotricha) and a new name (Dendrobium bougainvilleanum) are also proposed for fitting recent systematic alterations within Orchidaceae.
