hyaline, small and quadrate above. Perich. bracts elongate, inner

Intermediate between D. montanum and Scottii, and remarkable for the 

 great brittleness of the leaves. D. stricium, Schleich, and fyagilifolium, Lindb. 

 are also closely allied species. This plant may have been imported attached 

 to the wood on which it was found, and thus its very limited area accounted 

 for ; it is scattered sparingly throughout Central Europe from Sweden and 

 Finland to Italy.
