John Duff
John Duff is a retired physician who retired to the town of Greyton, South Africa. In order to keep active he has explored the mountains surrounding his town and offered to show me this outstanding Disa uniflora site, the Greyton Grotto. He has made an extensive investigation of the area surrounding Greyton and the only place that has such a provision of flowers is in the grotto shown below.
The following pictures were taken around the Grotto.
