Continuing herbarium and literature studies of Philippine orchids have revealed a variety of new and noteworthy data. Two new monospecific genera and their species are proposed, namely Samarorchis sulitiana and Santotomasia wardiana. One new species in an established genus is also proposed, namely Micropera edanoi. One replacement name is proposed for the homonym Liparis monophylla, viz. L. carnicolor. Liparis viridicallus Holttum is newly recorded for the Philippines and seven taxa are proposed as synonyms of earlier entities. Two names are lectotypified, namely L. grandis and L. jarensis.
