32. Benstonea pectinata (Martelli) Callm. & Buerki , comb. nova.

≡ Pandanus pectinatus Martelli in Boll. Soc. Bot. Ital. 1904: 304. 1904.

Typus: MALAYSIA. Sarawak ( Borneo): Beccari s.n. ( holo-: FI [ FI003941 , carpo.] image seen).

Distribution and ecology. – Benstonea pectinata occurs in the montane rainforests ( 900-2500 m) of Borneo and has been collected twice in Sumatra ( STONE, 1975a, 1978).

Observations. – This species is strictly epiphytic and easily distinguished from other epiphytic members of the genus (e.g. B. alticola ) by its lobed auricles at the base of the leaves. Benstonea pectinata has often been collected on fallen trees in montane rainforests, but seems to be a strict epiphyte ( Fig. 5B ).
