Identification. Pothos insignis is apparently allied to P. rumphii Schott and P. borneensis Furt. in having long petioles with a petiolar sheath extending to the base of the geniculum, a relatively large, leathery spathe and robust tepals. Pothos insignis is distinguished from P. rumphii and P. borneensis by the manner in which the inflorescences are presented. In P. insignis new fertile stems arise from leafess, post fertile stems. The new fertile stems are clothed along their entire length by inflated cataphylls each consisting of a greatly enlarged petiolar sheath terminated by a much-reduced leaf blade. From the apex of each fertile stem emerge the inflorescences, one at a time, each new inflorescence emerging as the previous one begins to fruit. It is unclear how many inflorescences a fertile stem produces before it dies, but a study of the scarring of post fertile stems suggest that it may be as many as 12 ( Boyce and Poulsen 1993).
Distribution and ecology. Northwestern, southwestern, and northeastern Sabah. Lianescent, hemi-epiphytic or lithophytic trunk or treelet climber at base of ridges or near rivers in primary to disturbed primary mixed dipterocarp forest on shales or limestone, at 10–1200 m elev.
