1 Nepenthes truncata is not likely to be confused with any other species on account of its strikingly truncate to deeply notched leaf blade apex, large size and lid with a basal glandular crest. The species appears to be very restricted in distribution, being found only in the highly ultramafic north-eastern corner of Mindanao as are N. bellii, N. merrilliana, and N. petiolata. Nepenthes truncata shows affinities to the N. maxima group in its strongly petiolate leaves, appendaged pitcher lid, 2-flowered partial peduncles and the venation of the leaf blade. Nepenthes truncata is still only known from a few fragmentary collections. 2. Macfarlane cites two collections in the protologue, one (Bolster 270) comprising a small, juvenile leaf, the other (Allen 191), which is illustrated, a large mature leaf. Although we have not been able to see the PENN material, this latter specimen seems the most appropriate for lectotypification.
