12 MK, BUKBTJBY ON THE BOTANY OF MADEIRA. 



caTts 



streams below the Arrebentao Peak. 



Asplenium marinum, Trequent on the north coast, especially 

 near the mouth of the S. Vicente Eiver *. I nowhere saw it much 

 above the sea-level. It has been found on the south coast, at 

 Camara dos Lobos and Santa Cruz. 



Asplenium Canariense, W. On moist mossy stone walls and 

 rocts, on the north side of the island, in many places : Punta 

 Delgada, Boa Ventura, Arco de S. Jorge, and in the ravines that 

 run down to Payal ; most commonly at a moderate elevation, like 

 A. palmatum. I understand it has been found at Eibeiro Frio. 

 To the south of the dividing range it is wanting or very rare. 



Asplenium lanceolatum, Huds. On walls near N. S. do Monte, 

 and in one or two other places not far from Punchal. 



Asplenium acutum^ Bory (according to Webb and Berthelot, 



and to Newman, Brit. Perns, ed. 3) {A. productum, Lowe). One 

 of the most common Ferns throughout Madeira, from the coast up 

 to at least 4000 feet of elevation. In the neighbourhood of Fun- 

 chal it is the most common of all. It is very difficult to decide 

 whether this be really distinct from A. Adiantum-nigrum. The 

 latter is a plant so excessively variable, that it seems hardly pos- 

 sible to set limits to its sportiveness ; but on the other hand, much 

 as the plant of Madeira and Teneriffe varies in size and develop- 

 ment, I have never seen it assume exactly the common appearance 

 of Adiantum-nigrum, The difterences are not owing merely to 

 luxuriance, for some of my Madeira specimens, not above 8 inches 

 high, have all the characters of acutum strongly marked, while 

 some oi Adiantwu-nigrum from Ireland, 14 or 15 inches high, have 

 all the characteristic marks of that species. 



Athyrium Filioc-foemina. Frequent in moist and shady places on 

 both sides of Madeira. 



Allantodia umhrosa^ E. Br. In very wet and shady ravines : 

 Eibeiro Frio, Metade Valley, and near the Santa Luzia waterfall. 

 A very beautiful Fern. 



Scolopendrium vulgar e^ Sm. Seemingly rare in Madeira : I saw 



it only in the Santa Luzia ravine, where it grows sparingly and 

 small. 



Ceterach officinarum^ AV. On walls here and there in the neigh- 

 bourhood of FunchaL It is remarkable, that this, which is one of 

 the most common Ferns in the south of Europe, should occur so 

 sparingly in IMadeira. 



Some of the specimens gathei-ccl here are a? much as 2 feet high.
