Goodness me, the names just bear almost no relationship to modern pteridology!\u00a0 The big Leiden monograph of Pyrrosia<\/em> was in the 1980s, where the name P. mollis<\/em> was explained! Nearly 40 years out of date.<\/div>\n
This species is Pyrrosia porosa<\/strong><\/em> (syn.: P. stictica<\/em>) – but was at one time mistakenly referred to P. mollis<\/em> in India.\u00a0P. mollis<\/em> is a synonym of\u00a0 the Malesian species, P. penangiana<\/em>, which does not occur in or near India.<\/div>\n<\/div>\n
