A synopsis of Philippine Cyrtandra (Gesneriaceae)

A taxonomic synopsis of Philippine Cyrtandra (Gesneriaceae) is presented. Following a study of 138 published names and their types, we accept 98 Cyrtandra species for the Philippine flora. Except for C. angularis, C. elatostemoides, and C. yaeyamae, all are endemic to the country. Lectotypes or neotypes are designated for all names for which this is necessary, except for six names for which we were unable to locate original material. We also validate a species name that was previously described without a Latin diagnosis (C. peninsula), synonymize three names, and provide taxonomic notes for each species. In addition, we propose two replacement names for taxa for which a legitimate name in Cyrtandra does not currently exist: C. edanoi for a Philippine species and C. siporensis for a Sumatran species. A look-up table is provided to facilitate referencing of currently accepted names in Philippine Cyrtandra.
