Remarks

The name refers to the numerous apical cells on the scale tips; these cells resemble the head of Medusa, one of the Gorgons in Greek mythology, which had snakes instead of hair (Latin, caput = head). Melpomene caput-gorgonis grows in wet montane forests and elfin forests at 2680–3200 m in southern Peru and Bolivia (Fig. 7B). The most distinguishing feature of this species is the broad scales with the abundant apical papillae. No other species of Melpomene has scale apices that provide a base for papillae several cells wide. Melpomene flabelliformis can be distinguished from M. caput-gorgonis by its distant fronds and glabrous or glabrescent petioles (vs. fronds close and petioles persistently hairy in M. caput-gorgonis). Melpomene flagellata is generally more slender in habit and most features, i.e., laminae to 9(–16) mm wide (vs. to 22 mm), rhizomes thinner and ascending, petiole scales narrower, and hairs in the sori longer. Melpomene caput-gorgonis grows together with M. paradoxa, which can be distinguished by its longer, glabrescent petioles and shorter segments; the latter species also forms patches with the fronds erect to arching whereas M. caput-gorgonis grows solitary with arching to pendent fronds.
