Abstract

Pittosporum (Pittosporaceae, Apiales), an attractive genus of horticulturally important trees and shrubs, is revised for Malesia (Malaysia, Singapore, Indonesia, Brunei Darussalam, the Philippines, Timor-Leste) and Papuasia (Papua Barat (Indonesia), Papua New Guinea and the Solomon Islands). In this report, 52 species are recognised, including many species reinstated from synonymy. Three taxa are raised to species rank (P. owenstanleyense, P. patelliplacenta and P. purpurascens), one is a new combination in Pittosporum (P. impressum), and four new species are described: P. sulawesiense, P. isolatum, P. schoddei and P. sogeriense.

Keywords: Indonesia, Malesia, Malaysia, New Guinea, Papuasia, Philippines, Pittosporaceae, Pittosporum, revision.
