This fern, by some authorities regarded as a hybrid of A. spinulosum with A. cristatum, 

 is found in swamps and wet places in woods and thickets. It is partially evergreen, 

 especially the barren fronds, and, growing in a crown, attains a height of If to 3 feet. 

 The sterile and fertile fronds are somewhat unlike, the former being shorter, somewhat 

 less compound, and generally produced a little later in the season. A third set of fronds 

 is produced in summer, intermediate in size and with broader, blunter pinnules, which 

 may be either barren or fertile. Rootstock stout, creeping or ascending, chafTy, and cov- 

 ered with old stalk-bases ; stalks shorter than the fronds, stout, chaffy especially when 

 young with large, pale brown scales ; fronds erect, deep green, firmly membranaceous, 

 elongated-oblong or elongated-lanceolate in outline, 1 to 2 feet long, smooth above but 

 slightly chaffy with sometimes a few stalked glands below, nearly bipinnate ; pinnae very 

 short-stalked, the upper lanceolate from a broad base, the lower triangular-lanceolate and 

 broadest at the very base, with the inferior basal pinnules but little if any longer than 

 the superior ; pinnules broadly oblong, obtuse, the lower pinnatifid, the upper merely 

 serrate with short, spinulose teeth ; indusia minutely glandular. 



Our recorded stations for this fern are very few, but a more careful search would pro- 

 bably prove it to be less extremely rare. Bellahill, thirteen miles from Halifax, and near

A low, lance shaped, evergreen fern, 4 to 14 inches high, with a pleasant aromatic 

 odour resembling that of strawberries, the odour remaining even in the dried fronds and 

 becoming much more obvious when they are soaked in water. It grows in the crevices
