J.Sm. var. poeppigii (Kunze) C.Chr., Kongel. Danske Vidensk. Selsk. Skr, Naturvidensk. Math. Afd. , ser. 8, 6: 127. 1920. Range:— Southern Bolivia ( CH , SC, TA); northern Argentina ; central Chile . Ecology:— Uncommon; terrestrial along humid forest edges; 2000–3100 m , 1450–2800 m in Argentina , 100–500 m in Chile . Notes:— Hypolepis poeppigii is characterized by inermous petioles and rachises, rachises, pinna-rachises, and costae clothed with both catenate and glandular hairs, glabrous laminar tissue between the veins abaxially, submarginal sori, and absence of pseudo-indusia. In its submarginal sori lacking pseudo-indusia, Hypolepis poeppigii resembles H. rugosula (Labill.) J.Sm. , a subcosmopolitan species ( Schwartsburd & Prado 2014 ). Hypolepis rugosula has not yet been recorded in the Andes ( Schwartsburd & Prado 2014 , 2015 , 2016 ) but is expected to occur there. Hypolepis poeppigii differs from H. rugosula by the dark brown petiole bases ( vs. burgundy), light brown to stramineous rachises ( vs. burgundy), subequilateral proximal pinnae ( vs. equilateral), and veins glabrous abaxially ( vs. with catenate-glandular hairs).
