Introduction
Pioneering investigations on the diatom flora of the Himalayas date back to the 19th century (Ehrenberg1854, Dickie 1882). After a long hiatus when few diatom taxa were described from this
region, there has been renewed attention to this topic. Recent efforts over the last 20 years include
studies on taxonomy and ecology of the Himalayan diatom flora (e.g., Ormerod et al. 1994,
Nautiyal et al. 1995, 1996, Jüttner et al. 1996, Rothfritz et al. 1997, Nautiyal & Nautiyal 1999,
Wojtal et al. 2010, Jüttner et al. 2010). The focus of the present communication is to further the
knowledge of Gomphonema flora of the Northern part of Indian subcontinent and describe two
new species of this genus from a stream descending from lesser Himalaya into the Doon Valley.
