110 4. PTERIS, L.

1. Pteris vespertilionis, Lab.; Fl. Nov. Roll. vol. ii. p. 96. t. 245. Brown, Prodi: p. 154.

Hab. Lord Auckland's group and Campbell's Island ; very common on rocks near the sea.

These specimens, which are small, accord with others gathered in Tasmania. The veins are generally free, but in the broader pinnules the upper primary one often unites with that of the segment below it. The P. Brunoniana of New Zealand (A. Cunn. Prodr. Fl. Nov. Zel. in Comp. Bot. Mag. vol. ii. p. 365.), has the veins much more anas- tomosing, in which respect it differs from the plant of New Holland. This is also the case in specimens of a very similar plant from Brazil, the Mauritius, Juan Fernandez, and the Philippine Islands. The more simple veined species is apparently an inhabitant of New Holland, Tristan d'Acunha, and the Cape of Good Hope.

The Lord Auckland's group specimens, growing in the immediate neighbourhood of the sea, have a very succulent habit.

5. LOMAEIA, WUld.

1. Lomakia procera, Spreng. Syst. Teg. vol. iv. p. 65. A. Cunn. Prodr. Flor. Nov. Zel. in Comp. Bot. Mag. vol. ii. p. 363. L. procera var. teginentosa, Hombr. et Jacq. in Voy. au Pole Slid, Bot. Monocot. Crypt. t. 2. E. sine descript. Stegania procera, Brown, Prodr. p. 153. A. Rich. Flor. Nov. Zel. p. 86. 1. 13, fertile frond only. Bleehnum, Siv., Lab. Flor. Nov. Holl. vol. ii. p. 97. t. 247.

Hab. Lord Auckland's group and Campbell's Island ; abundant, especially by the banks of streams and in watery places, ascending to the tops of the lulls where it is very stunted.

This is the ordinary New Holland and Tasmanian form. M. A. Richard, in the Flor. Nov. Zel., gives an excellent figure of the sterile frond along with the ban-en state of another, probably the following, species.

2. Lomaria lanceolata, Spreng. et A. Cunn. locis citatis. Stegania, Brown et A. Rick.

Hab. Lord Auckland's group and Campbell's Island; in woods close to the sea abundant.

6. POLYPODIUM, Sw.

1. Polypodioi viscidum, Spreng. Sp. PI. vol. iv. p. 61. Cheilanthes viscosa, Carm. in Linn. Soc. Trans. vol. xii. p. 511. non Link. C. fragilis, Carm. in Herb. Hook. " Polypodhun villoso-viscidiun, Auhert dii Pet. Thonars, Flore de Trist. d'Acunha, in Mel. de Bot. p. 44." Carm. 1. c.

Hab. Lord Auckland's group and Campbell's Island ; moist places on the hills, especially under the shelter of bushes.

My specimens entirely accord with Capt. Carmichael's in Herb. Hook. Very similar plants inhabit other islands of the Southern Hemisphere, which have been placed in Polypodium or Cheilanthes, according to the views entertained by the authors of the several species as to the nature of the recurved apices of the lobules, which, especially in a young state, cover the sori. The species most nearly allied to this are the Pohjpodiuni viscosum of Pritchard's 'Catalogue of St. Helena plants,' the J', viscidum of Colenso MSS., a native of New Zealand alluded to in a catalogue of those collected by Mr. Stephenson (vid. Hook. Lond. Bot. Journ. vol. iii. p. 413.), and a Juan Fernandez species in Herb. Hook., bearing the name of P. spectal/ile, Kaulf. ?, in Mi-. Bertero's hand-writing ; all these have the sori invariably placed close to the margm of the segments, in whose concave apices they are somewhat sunk. The P. rugosulum (Lab.Fl. Nov. Holl. vol. ii. p. 92. t. 241.), another closely albed plant, is retained in this genus by Mr. Brown (Prodr.
