Soeotra. On the Haghier hills above Tamarida. B.C.S. n. 447. 

 Distrib. Cape de Verde Islands, Africa (Abyssinia and the Cape), and 

 warmer regions of the old world generally. 



2. N. molle, Desv. Mem. Soc. Linn. vi. 258 ; Hook, and Baker Syn. Fil.

Identical with Polypodium parasiticum, Linn. (Sp. 1551), which name by 

 rules of nomenclature followed by vascular cryptogamists should be adopted. 

 C. B. Clarke (in Trans. Linn. Soc. ser. 2, i. (1880), 538) takes it up, but, as is 

 pointed out in Synopsis Filicum, "the name molle is so thoroughly established 

 for the species that it seems a pity to drop it."
