Remarks
Protologue: Melpomene huancabambensis grows in montane forests at 1900–2200 m in northeastern Peru and southern Ecuador (Fig. 7D). This species is an ally of M. pilosissima, with which it matches in the densely hairy, terete petioles and the hairy laminae, which may have hairs along the segment margins and the adaxial surface. It is characterized by the lack or poor development of hydathodes (vs. always present and well-developed in M. pilosissima). The often large size of the plants, relatively short petioles, and the predominantly patent segments of M. huancabambensis create a habit that is quite different from that of M. pilosissima, where the petioles tend to be longer and the segments more ascending. Melpomene pilosissima further differs from M. huancabambensis in being usually less hairy on the segments adaxially; however, there are some exceptions. Some plants of M. pilosissima are equal to M. huancabambensis in the hairiness of the adaxial segment surfaces, but tend to have more acute segment tips, discontinuously visible midveins, and decurrently marginate petioles (all characters not present in M. huancabambensis).
