8. Benstonea biplicata (H. St. John) Callm. & Buerki View in CoL , comb. nova.

≡ Pandanus biplicatus H. St. John View in CoL in Pacific Sci. 17: 466. 1963.

Typus: THAILAND. Jaujau: lower Siam, Kopah, 9.XII. 1917, Md. Haniff & Md. Nur SFN 2703 (holo-: SING [ SING0032172 View Materials ]! ; iso-: K [ K000781297 ]!).

Distribution and ecology. – Benstonea biplicata is restricted to southern Thailand, close to the Malaysian border ( STONE, 1968b).

Observations. – This species was placed in Pandanus sect. Fusiforma by STONE (1968b), a section that we have not included in Benstonea (see above). Careful examination of the type in SING showed that its leaves (c. 4 100 cm) and styles (sharp and narrow) are similar to those in all the other species of Benstonea . Benstonea biplicata is therefore excluded from Pandanus sect. Fusiforma and transferred here to Benstonea . It is morphologically similar to B. nana (Martelli) Callm. & Buerki , but differs in possessing a larger syncarp. Pending taxonomic revisions in the region should help clarify the status of this taxon.
