Geonoma undata subsp. skovii (Henderson, Borchsenius, & Balslev) Henderson , comb. & stat. nov. Basionym: Geonoma skovii Henderson, Borchsenius & Balslev (2008: 60) . Type: ECUADOR . Morona-Santiago : along the Limón-Cuenca road 4 km above Plan de Milagro, 3°04’S , 78°30’W , 1920 m , 19 May 1988 , B. Bergmann & H. Pedersen 62589 ( holotype NY!, isotypes AAU!, QCA n.v.). Leaves veins raised and rectangular in cross-section adaxially; basal pinna 1.3(0.6–2.0) cm wide; apical pinna 7.3(2.7–11.3) cm wide. Inflorescences prophyll margins with irregular, spine-like projections; flower pits usually spirally arranged, distantly spaced. Distribution and habitat:— From 2°40’– 3°38’S and 78°00’– 78°30’W in Ecuador on eastern Andean slopes at 1778(1470–1920) m elevation in montane rainforest ( Fig. 43 ). Subspecific variation:— There is geographic discontinuity, and specimens come from three different mountain areas. Specimens from the Cordilleras Cutucú and Cóndor have more pinnae per side of the rachis than those from the eastern slopes of the main Cordillera. However, there are too few specimens to test for differences. Jean-Christophe Pintaud (pers. comm.) reports that this subspecies also occurs in adjacent Peru .
