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.
REPORT OH BURBIDGE’S FERNS OF THE STJLU
ARCHIPELAGO.
B y J. G. Baker, F.R.S., F.L.S.
T he 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 :—

4.* P t e r is T r e a c h e a r ia n a , Baler, n. sp.—Near P. cretica, but
much more slender and delicate in general aspect, with the lowest

request of Mr. Burbidge in compliment to the Honourable W. H.
Treacher, Acting Governor of Labuan, whose kindness and help
contributed materially to the success of his expedition.
