Benstonea toei (H. St. John) Callm. & Buerki , comb. nova. ≡ Pandanus toei H. St. John in Pacific Sci. 17: 468. 1963 . Typus: THAILAND : Krabi , 83 km from Huay Yawt , 28.I. 1958 , Tem Smitinand 4143 ( holo- : BKF [ SN080179 ] image seen). Distribution and ecology . – Benstonea toei is endemic to lowland evergreen forests in Thailand and Peninsular Malaysia . Observations . – This species is morphologically similar to B. humilis but lacks the tesselate venation and armed pleats on the leaves that characterized the latter. Furthermore, B.toei has a syncarp with fewer and smaller drupes (160 drupes of 15-18 mm longvs 240-430 drupes of 20-25 mmin B.humilis ) . Benstonea toei was strangely omitted from STONE’ s (1978) revision of Pandanus subg. Acrostigma .
