A surprisingly tricky species for me in my growing conditions! Lovely tubby pitchers!
From Borneo Exotics: "Endemic to the island of Mindoro in the Philippines, this under-appreciated species is as easy to grow as Nepenthes ventricosa and an ideal beginners plant. We find the hard woody pitchers exceptionally attractive, being red flecked on a yellow/green background with lustrous scalloped peristome. If pruned back it will form dense clusters of basal growths and many pitchers, with it being rare to find a leaf not developing a pitcher. The red-spotted pitchers are up to 20 cm tall and have a wide red peristome."
