3. Hybrids between this species and N. gracilis (N.trichocarpa) and N. rafflesiana (N.hookeriana) are widespread though scarce, and are treated in this account. 2. The species is apparently absent from the Moluccas and Sulawesi, but the eastern (New Guinea) and western (Thailand to Borneo) populations are morphologically indistinguishable. 1 The globular pitchers of N. ampullaria with their reflexed linear-oblong lids are not easily confused with any other species. The habit of this species is characteristic, with numerous rosettes sunken in the leaf litter or moss of the forest floor, and tall climbing stems which lack upper pitchers, though pitchers may be borne in rosettes arising from stems up to 2 m from the ground. Recently a few isolated cases of plants bearing upper pitchers have been reported in Brunei and Peninsular Malaysia. These are small, infundibuliform pitchers no more than 2 cm high, but extremely uncommon.
