INTRODUCTION: Plagiochasma intermedium Lindend & Gottsche, Andhra Pradesh is the seventh largest state Riccia frostii Austin, Riccia poihaniana A.E.D. in Indian union, it covers an area about 162, 970 sq.

The state comprises 13 districts, Riccardia levieri Schiffner., Riccardia tenuicostata there are two areas namely called Rayalaseema and Schiffn. and Riccardia villosa (Stephani) S.C. Costal Andhra. The state is having about 17.86 Srivast. & Udar. Perusal of previously published percentage of forest cover (FSI, 2019), major portion literature (Rao et al., 1999; Bapna & Kachroo 2000; of Eastern Ghats hill ranges, it is also having Sowghandika, 2010; Dandotiya et al., 2011; Sandhya different types of vegetation’s, nearly more than 180 Rani et al., 2011a & 2011b; Sowghandhika et al., waterfalls (seasonal and perennial) and different 2011; Sandhya Rani et al., 2012; Sandhya Rani et al., types of altitudinal variations from sea level to 1680 2014; Sreenath & Ravi Prasad Rao 2019; Asthana & meters of above mean sea level.

Hence the localities and different districts of the state of Andhra present collection forms are new distributional Pradesh. After critical examination of the specimens records to the state, and the present report adds ten identified belongs to Asterella khasiana (Griff.) more liverwort species to Bryoflora of Andhra Grolle., Plagiochasma cordatum Lehm. & Lindenb., Pradesh, India. https://biosciencediscovery.com 111 ISSN: 2231-024X (Online) Ananthaneni Sreenath and Boyina Ravi Prasad Rao MATERIALS AND METHODS or two rows in cross section, air chambers empty; Extensive field explorations were conducted pores bounded by 3 – 4 concentric rings, with 6 or 7 during 2016 – 2019.
