The sequence is again continued on the north side bench 

 with the cliff-brakes, Pellaea, the maiden-hair ferns, Adiantnm 

 (which occupy the space as far as the entrance to the aquatic 

 house, no. 9), thence continued along the south side bench with 

 the brake, Pteris, the golden and silver ferns, Ceropteris, the 

 spleenwort ferns, with such genera as Diplazinm, Asplenium, 

 Neottopteris, the bird's-nest fern, Blechnum, and Woodwardia, the 

 chain-ferns. The sequence is then taken up on the end of the 

 central bench near the entrance to the aquatic house with Dry- 

 opteris and Polystichum, the shield-ferns, Tectaria, and Olfersia, 

 terminating with the genus Nephrolepis, to which the Boston fern 

 belongs, and Davallia and its allies, at the other end of the 

 central bench. On the upper portion of this central bench 

 will be found specimens of some of the foregoing genera which 

 are too large for insertion in the sequence. The Salviniales are 

 represented by the genera Azolla and Sahnnia of the Salvini- 

 aceae, and by Marsilea of the Marsileaceae, occupying a posi- 

 tion on the south side bench ; and are followed by the Lycopodi- 

 ales, represented for the greater part by the genus Selaginella, 

 which fills out the remainder of the side bench and is terminated 

 on the small end bench against the partition separating this house

On the corner bench to the right, as one enters from house no. 

 12, is the main collection of the stag-horn ferns, Alcicornium. 

 In some species this resemblance to stag-horns is very marked, 

 as in Alcicornium bifurcatum, the commonly cultivated form of 

 this genus, from temperate Australia, A. Hillii, from Queensland, 

 and A, Willinckii, from Java. Immediately opposite to this group 

 is a large plant of the Boston fern, Nephrolepis exaltata, common 

 throughout tropical America and also in Florida. To the left of 

 the entrance to house no. 10 are some climbing ferns, repre- 

 sented by the genus Lygodium. A little further on to the left of 

 the walk is Cibotium Baromctz, from China and Tartary, the
