Начальная страница : Protologue: Melpomene jimenezii grows in elfin forest and moist montane forests at 2400–3800 m in Peru and Bolivia (Fig. 7D). This species is remarkable because it lacks conspicuous hydathodes in most fronds. Occasionally, some segments have small hydathodes, while hydathodes are otherwise absent on the same frond. Other species with such irregular development of hydathodes are M. huancabambensis and M. michaelis. According to Parris (1997), absence and presence of hydathodes may change in many grammitid taxa in the Paleotropics, but until now it has been considered a reliably constant feature for the Neotropical genera. The prevailing lack of hydathodes separates M. jimenezii from the superficially similar M. firma, which always has well developed hydathodes and also differs in having conspicuous black midveins (vs. midveins not visible or obscure in M. jimenezii) and fewer, shorter hairs on the petioles (vs. densely long-hairy). From Melpomene pilosissima, M. jimenezii differs in having longer segments, ciliform hairs clustered in the sori (vs. evenly distributed on the laminae), and in lacking setiform or ciliform hairs along the margins and the adaxial laminae (vs. regularly hairy along the margins and the adaxial laminae). The smaller M. michaelis is similar, but differs from M. jimenezii by having setiform and ciliform hairs on the laminae between the sori (vs. restricted to the sori), lacking red stomata (vs. stomata often red), and having rhizome scales about half the size of those of M. jimenezii (2.0–3.0 vs. 5.5–7.5 mm long).
