Notes
2. Herbarium specimens fall largely into two forms, those with upper pitchers infundibulate, with a sub-triangular lid, and those with narrow, pencil-like, tubular pitchers with an orbicular lid. Clarke, Nepenthes of Borneo (1997), has drawn attention to the possibility that this species specialises in trapping termites.
1 This species is sometimes confused with N. gracilis, but is immediately distinguished from this and all other species by the bright white (less usually brown), narrow band of densely packed silky hairs just below the peristome and the dense long coppery red indumentum on young stems and leaves.
