Pyrrosia penangiana (Hook.) Holttum(= Pyrrosia mollis (Kunze) Ching) epiphytic wild fern from Western Ghats Tamilnadu

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 Nearly 40 years out of date.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