species, they all grow the better for a little extra lieat : even 

 the stove does not seem too hot for them, especially while 

 young. The most distinct of these varieties are A. marinum 

 ramosum, fronds usually forked so as to appear like two 

 fronds joined ; A. marinum trapezlforme, with more triangular 

 fronds ; and A. marinum sub-bipinnatum, with the pinnae deeply 

 divided. 



A. OBTUSATUM (Blunt-fronded). A very handsome Fern, 

 native of New Zealand. Fronds rigid, erect-growing, leathery, 

 bright green, and pinnated. It is a dwarf species, seldom 

 growing more than 9 inches high ; pinnae bluntly oblong, 

 rounded and serrated at the margin. Stalk always winged, 

 covered with scales. A very remarkable and well-defined 

 species. Messrs. Osborne, of Fulhain, cultivate this handsome 

 Fern on the floor of their greenhouse very successfully. 

 Increased by division. 



A. PALMATUM (Hand- shaped). A handsome Fern, native of 

 the Canary Islands. Fronds simple, but deeply divided into 

 five lobes, hence its specific name ; growing only 10 inches 

 high. Increased by dividing the creeping rootstock. This 

 Fern is more generally known as A. hemionitis. There is a 

 variety with the points of the lobes divided and almost tufted. 



A. POLYODON (Many-toothed). Another handsome Fern 

 from New Zealand. Fronds pinnated, lance-shaped, growing 

 2 feet long; pinnse nearly square, with long stems. Each 

 pinna is divided into segments, and each segment has two 

 divisions or teeth: hence its name Many-toothed. Stems 

 scaly. Increased by division. 



A. EECLINATUM (Reclining). A very pretty small-growing 

 Fern from the Island of St. Helena. The pinnate fronds droop 

 gracefully on every side of the central crown, and young plants 

 are produced at their points. It may therefore be readily 

 increased. 



A. UMBROSUM (Shady). This plant will succeed in a warm 

 greenhouse. See what is said of it in the Stove division.
