Abstract

Aulacopilum glaucum, in the family Erpodiaceae, has recently been identified from Manipur in north-east India, and is new to the Eastern Himalayas. It was earlier reported from the Western Ghats (Daniels et al. 2012), Eastern Ghats (Asthana and Srivastava 2016) and the Western Himalayas (Sahu and Asthana 2016). In India there are 4 species of Aulacopilum Wilson (Lal 2005; Daniels et al. 2012). Aulacopilum glaucum can be easily recognised by the presence of dimorphic leaves; broad dorsal leaves and narrow ventral leaves with numerous rhizoids. The plants were bright green, with an irregularly branched, creeping stem, 12–15 mm long. Leaves were in four rows (2 dorsal and 2 ventral), closely imbricate, complanate, ecostate and papillose with crenulate margins. The dorsal leaves were ovate-lanceolate, 0.64 × 0.32 mm, whilst the ventral leaves were narrowly lanceolate, 0.48 × 0.16 mm.
