Sicksonia. 



D. Oulcitu, L'Herit. Hab. : Maiaiia (very rare), and the Azores. 

 In the latter islands, on mountains of 2-3,000 feet of elevation, 

 so abundant that the dense woolly covering of the rhizome has 

 now become an article of commerce. 

 Hymenopbyllum. 



H. Tun bi'idg ense. Smith. Hab. : Madeira, on very wet shaded 

 rocks, by the side of the levada, or aqueduct, between the Ribeiro 

 Frio and Metade valleys ; very plentiful. All well-marked ex- 

 amples of H. Tunbridyense, not approaching to H. IVil.ioni. In the 

 Canary Islands and Azores, T£. imilatei-ale ( = H. Wilsoni, Hook.). 

 In the islands of Floras and Gorvo. Hook. Brit. Ferns, t. 43. 

 Trichoiuaiies. 



T. radicans, Swartz (T. speciosum, IVilld.). Hab. : Ma^eij^, in the 

 same locality with the Hymenophyllum ; very sparingly. 'In 

 Tenerifte, in the greatest profusion in the wood of Agua Garcia, 

 at the elevation of about 2,.500 feet.' — C. Bimhiiry. In Azores. 



* ' ]\I:ideira is famous for its abundance of Ferns. On the northern slope they 

 grow in surprising profusion. In all the ravines which intersect that coast, we 

 see. them clothing the roclvs and shady banks, the roots and trunks of trees, the 

 margins of the innumerable rapid streams, and the moist and mosM^ walls. 

 Even in the Adllages they abound. The beautiful Hare's-foot fern, Daraltia 

 Canariennis, and the Polypodium imlgare, appeared to me the most generallj^ 

 common ferns throughout the island. They are frequent even in the immediate 

 neighbourhood of Funchal ; and on the nortliern side of the island, there is hardly 

 a damp wall or an old mossy tree on which they do not flourish. Xear the 

 mouth of the St. Vicente river, 1 saw them groivnig (in a stunted condition cer- 

 tainly) among the loose stones of the actual sea-beach. It is on old trees in the 

 mountain woods of Serra d'Agiia and Eibeiro Frio that they are niu>t luxuriant 

 and beautiful ; and then they ascend to an elevation of at least .5,000 feet above 

 the sea-level.' — Jimnal nf Linnman Sncietij, Marcli I8JC : Remarks on the Botany
