| * | Asplenium tomentosum, Hook. |
| 207.* | Asplenium (Diplazium) xiphophyllum, Baker, n. sp.—Comes near A. pallidum, porrectum, and cultratum. |

| | Polypodium alternidens, Cesati, Fil. Born., p. 25, tab. 2, fig. 4. Of this Burbidge’s bundle contains a
single specimen. It is a well-marked new species, discovered by Signor Beccari in
the neighbourhood of Sarawak. |
| * | Polypodium cucullatum, Nees. A small slender form. |

It will be seen that altogether Mr. Burbidge has added above fifty species to the fern-flora of the island. His exploration quite bears out the idea that we previously entertained, that the fern-flora of the island is very rich, and that there is still a plentiful harvest to await the exploration of the interior. The added species which are not new are nearly all already known in Java and the Philippine Islands, frequently in both.

The Sulu Archipelago is a group of small islands lying between Borneo and the Philippines. They are for the most part under cultivation; but there are two mountains which attain an elevation of between two thousand and three thousand feet. So far as I am aware their botany is entirely unknown. The following is a full catalogue of the ferns which Mr. Burbidge gathered in the group:—

| | Pteris quadriaurita, Retz. |
| 4.* | Pteris Treacheariana, Baker, n. sp.—Near P. cretica, but much more slender and delicate in general aspect, with the lowest one to three
pairs of pinnæ two to three forked. Named at the request of Mr. Burbidge in compliment
