Rhaphidophora latevaginata has petiolar sheath that is long-persistent (vs. very rapidly marcescent), mostly adnate (vs. mostly free) with the wings strongly unequal (vs. weakly or not at all unequal), shortly free-auriculate (vs. long, narrowly triangular free-ligulate) and petiole of R . latevaginata proportionately longer (petiole: blade ca. 1:5 vs. ca. 1:12) ( Ahmad Sofiman and Boyce 2010 ). Distribution and ecology. Northwest and northeastern Sabah . Primary to secondary moist lowland to hill dipterocarp forest on clay and sandstone. 50–840 m elev.
