Hello Pedro.
I moved Coronilla from the Main Page to the proper location on the Pipedia website, which is under the Heading Alternative Woods Used For Pipemaking http://pipedia.org/index.php?title=Main_Page#Alternative_Woods_Used_For_Pipemaking
This links to a page with all the Alternative Woods http://pipedia.org/index.php?title=Alternative_Woods_Used_For_Pipemaking
This in turn links to the seperate page for Coronilla
Therefore there is no need for a seperate entry for Coronilla on the Main Page, which is why I have deleted the duplicate entry.
Regards, Frank.
