"The MASTER "strikes again! Yes Ron, you are of course right. I had rather hoped the Rhododendron would have posed more of a challenge, it is a bit unusual, even the flowers are different. According to the RHS Plantfinder the Rhamnus has had a name change and is now Frangula alnus Aspleniifolium. It is apparently the host plant for the Brimstone butterfly.
Well, I happened to recognize those two anyway. For every plant put up here I think I know there are perhaps dozens I don't have a clue about - especially tropicals. http://www.bbc.co.uk/doctorwho/classic/gallery/delgado/index.shtml
