R – extremely rare
Asplenium trichomanes subsp. pachyrachis can hybridise with subsp. quadrivalens, forming a vigorous plant with a more upright habit than subsp. pachyrachis and distinctly intermediate between the parents. It is known as Asplenium trichomanes L. nothossp. staufferi Lovis & Reichstein.
A rapid investigation of natural sandstone outcrops, buildings, walls, … showed that Asplenium trichomanes nothossp. staufferi is easily found in areas where the two parents are present and grows on natural rocks as well as on man-made walls. At present date, 23 sites in 17 square kilometres are known.
The results of the investigation and the present distribution and status in Luxembourg can be found in:
