Abstract

New localities for Sararanga sinuosa are recorded, all from the Admiralty Islands, from where the genus has now been introduced into cultivation for the first time. Critical notes are provided concerning the placement of a number of species into sections of Pandanus. New sections described are sectio Karuka typified by P. brosimos Merr. & Perry, sectio Paralophostigma typified by P. limbatus Merr. & Perry, sectio Perrya typified by P. archboldianus Merr. & Perry, sectio Metamaysops typified by P. brachyphyllus Merr. & Perry, sectio Megastigma typified by P. rex B. C. Stone, and sectio Excavata based on P. antaresensis St. John. New species described are P. columbiformis (Papua) in sectio Lophostigma (Brongn.) Warb., P. clarkei (NE. New Guinea) in sectio Paralophostigma, P. galorei (W. New Guinea) in sectio Metamaysops, P. croceus (Admiralty Is.) in sectio Maysops St. John, P. navicularis (New Ireland) in sectio Bryantia (Gaud.) Warb., and P. rex (Papua) in sectio Megastigma. First accounts are given of staminate inflorescences in P. brosimos (sectio Karuka), P. antaresensis St. John (sectio Excavata), and P. leiophyllus Martelli (sectio Involuta St. John).
