Vogel 950012; 5 April 1997; Hetterscheid H.A.M. 477 (holo L, spirit collection). Identification. Amorphophallus tinekeae is a member of a group of exclusively Bornean species and most closely resembles A. borneensis Engl. & Gehrm., from which it differs by having a consistently short peduncle, strongly zygomorphic stigmas, and a rather narrow appendix (Hetterscheid and van der Ham 2001). Distribution and ecology. Endemic to Sabah. Known from the type locality in Gomantong Caves on karst limestone.Published as part of Wong, Sin Yeng & Joling, Jyloerica, 2021, Checklist of aroids (Alismatales, Araceae) from Sabah (Malaysian Borneo), pp. 931-974 in Check List 17 (3) on page 945, DOI: 10.15560/17.3.93

Rhaphidophora minor may look similar to R. sylvestris (Blume) Engl. when it is fresh, although the thinner, more prominently veined leaf and longer spathe beak of R. minor are diagnostic. Dried material of R. minor is notable for the uniformly pale straw-coloured leaves (Boyce 2001). Distribution and ecology. Northeastern Sabah. Swampy habitats in full sun, often along the banks of large rivers.
