Geek Notes
This spontaneous sterile hybrid was found in the British nursery of Mairis and Company sometime before it was named in 1885. One of parents is Adiantum capillus-veneris, a species with a very wide distribution. The other parent is unknown, but likely to be A. raddianum or A. aethiopicum.
