Notes
1 Nepenthes trichocarpa has sessile leaves which exhibit N. ampullaria -like venation, texture and hairiness, whilst the angular stem, with sub-decurrent leaf bases and the lid with its few, broad-bordered glands are similar to those of N. gracilis. The pitchers are characteristically barrel-shaped and slightly constricted at the mouth.
3. Holttum was the first to suggest that this species was a hybrid between N. ampullaria and N. gracilis. As with N.hookeriana this supposition is based upon the fact that it only occurs in mixed populations of the parent species.
2. At Bogor several duplicates of Teijsmann’s Sibolga collections exist; of these one duplicate of 532 represents N.trichocarpa, the remaining 2 sheets are N. gracilis. Of 533, one fragmented sheet may be N. gracilis, while the two other sheets are annotated N. trichocarpa var. erythrosticta, characterised by its larger size. Danser (1928) states that the number 532 represents authentic specimens of the var. erythrosticta, however. Without viewing the Utrecht specimens it is impossible to be certain of Miquel’s designation, since Teijsmann’s collections are mixed, and Miquel refers to no numbers in his protologues.
