N.gymnamphora, lower pitcher, inhabitat   Nepenthes pectinata  
N.pectinata sometimes also referred to as N.xiphioides, grows in the forested slopes of Gunung Talakmau in Central Sumatra, between 1000m and 2800m. This species is almost indistinguishable from N.gymnamphora except that it has a slightly more ovoid mouth and rarely produces upper pitchers. Forming basal rosettes within the forest litter, the pitchers are ovoid with a round mouth and small peristome.
