In Japan growers have collected and cultivated Psilotum pre edo period (1603-1867) and until now. Many of the forms where collected in the wild and new forms where created from them. Over the years many where lost but there are still a few that remain. I have dedicated this sight to the introduction and the preservation of these rare forms that could be new/old species.
In 1992 there was a pink book published on the topic of growing psilotum. Some of the info I have gathered has been from the help of interpreting the righting in this book threw the help of a friend. Some of the images will have Page # referring to the page in this book.
