Riccia boliviensis Jovet-Ast, New to Asia from India with Disjunct Distribution Beyond South America

Riccia boliviensis Jovet-Ast is recorded for the first time in Asia from the Eastern Ghats area of Andhra Pradesh (India). It is a disjunct distribution of this taxon recorded in Asia beyond South America as earlier it was reported from Argentina, Brazil, Venezuela and Bolivia (South America). The species can be readily distinguished in having spores exhibiting prominent triradiate mark and vermiculate sculpturing on its proximal face, while distal surface has sinuose ridges forming areolation at some places with tubercles at angles. Morpho-taxonomic account of Indian plants with distributional map is provided in the present contribution.
