Cyathea nilgirensis Holttum (Cyatheaceae: Pteridophyta): a threatened tree fern from central Western Ghats, India

While studying some of the exclusive and threatened swamps overgrown with wild nutmeg trees (Myristica swamps), in the Kathalekan forest of Uttara Kannada in central Western Ghats, Cyathea nilgirensis Holttum, a southern Indian endemic tree fern was seen growing in the deep shade of the swampy forest. This is a new report of its distribution anywhere from north of Western Ghats.
