Cheilanthes mysorensis<\/em><\/p>\n

That’s a very widespread species Cheilanthes tenuifolia<\/em>. Nowadays it is known that Cheilanthes<\/em> is a complex group of various different genera (though a bit over-split molecularly in N. America).\u00a0 The microgenus for this\u00a0 species was Cheilanthosoria,<\/em> according to the late Professor Ren Chang Ching (Beijing), but the correct and oldest name is Oeosporangium,<\/em> so nowadays it is Oeosporangium tenuifolium<\/em>.<\/span><\/div>\n
Current molecular work on the Cheilanthoid genera is being done in America and will be very interesting, but will likely be too oversplit into some unrecognisable “genera” for some groups.<\/div>\n
O. tenuifolium<\/em> occurs almost throughout India except the further west Himalaya (just getting into Uttarakhand, from Nepal, where it is very common)..
\n<\/span>It has strange roots with many tiny swollen lateral tips to each, suggesting possible mycorrhizal VAM symbiosis – which, if so, might explain why it is extremely difficult to get transplanted plants to survive – though I have managed it in Nepal some years ago after many tries.<\/div>\n

This is Oeosporangium tenuifolium<\/em>, native – is a cheilanthoid fern,
\nI think you had it before, already?<\/p>\n
