84 THE VOYAGE OF H.M.S. CHALLENGER. 



Moore, who, it may be added, compares bis species witb Adiantum fragile, Swartz, a West 

 Indian species remarkable for tbe very deciduous nature of its pinnules. 



Pteris aquilina, Linn., var. caudata. 



Pterin aquilina, Linn. Sp. PL, ed. 1, p. 1075, var. caudata, Linn., loc. cit. (species); Griseb., Fl. Brit. 

 W. InJ., p. 670; Chapm., Fl. Southern U.S., p. 589. 



Bermudas. — Indigenous. Common in tbe marsbes of Pembroke, Hamilton, &c. — 

 Hunter; Rein; Jones; Moseley; Lefroy. 



Tbe species is generally distributed in tbe tropics and in botb nortb and soutb temperate 

 zones; and some specimens of the American variety caudata are so like the New Zealand 

 variety esculenta as to be indistinguishable. 



Pteris heterophylla, Linn. 



Pteris heterophylla, Linn., Sp. PL, ed. 2, p. 1534; Griseb., Fl. Brit. W. ImL, p. 6fi8 ; Hook, and 

 Baker, Synop. FiL, ed. 2, p. 160. 



Bermudas. — Indigenous. Tbe caves — Far tow ; Moseley; Lefroy. 



A very remarkable and distinct fern, only known from the West Indies, where, 

 however, it is generally spread. The locality Rio, Brazil, Lady Calcott, recorded in 

 Hooker's Species Filicum, ii. p. 166, is almost certainly an error, arising from a mixture of 

 specimens ; for tbe neighbourhood of Rio has been very thoroughly explored, and no other 

 specimen exists at Kew from that country. 



Woodwardia virginica, Sm. 



Woodwardia virginica, Sm., Act. Taur., v. p. 412; Hook, and Baker, Synop. FiL, ed. 2, p. 188; 

 Chapm., Fl. Southern U.S., p. 591. 



Bermudas. — Indigenous. Pembroke Marsh — Lefroy; without locality — Rein. 



Eastern North America, from Canada to Florida. 



This appears to be quite rare in the Bermudas. 



Asplenium dentatum, Linn. 



Asplenium dentatum, Linn., Sp. PL, ed. 1, p. 1080; Hook, and Baker, Synop. FiL, p. 196; Griseb., 

 Fl. Brit. W. Ind., p. 683; Chapm., Fl. Southern U.S., p. 592. 



Bermudas. — Indigenous. The dell on the path to Paynter's Vale from H. Sound 

 — Lefroy; caves at Paynter's Vale — Moseley; without locality — Farlow. 

 Florida, West Indies, Mexico, and Guatemala. 



Asplenium (Diplazium) laffanianum, Baker. (Plate XII.) 



Asplenium (Diplazium) laffanianum, Baker in Gaid. Chron., n.s., xvii. p. 673. 

 Asplenium caudice erecto, paleis lanceolatis sordide brunneis, stipitibus semipedalibus 

 supra basin nudis ; frondibus oblongo-deltoideis bipinnatis glabris viridibus pedalibus,
