Hab. — Ash trees on the lawn of Kilkerran Castle, Dailly, Ayrshire, (y. Shmv, 

 June, i860)!! 



This rare species has some resemblance in the capsule to 0. striatum, but 

 is much smaller, and the capsule always shows some traces of bands, but no 

 cilia. Perhaps its natural position is near the var. Sturmii of O. rupestre, and 

 Venturi conjectures that it may be a hybrid between rupestre and striatum; 

 the Italian specimens referred to it by De Notaris, belong according to 

 Venturi, to 0. rupestre var. Franzonii.
