Another, Nepenthes Edwardsiania, has a narrow pitcher twenty inches long; while the plant itself grows to a length of twenty feet.
Ferns are abundant, but are not so varied as on the volcanic mountains of Java; and Tree-ferns are neither so plentiful nor so large as on that island.

They grow, however, quite down to the level of the sea, and are generally slender and graceful plants from eight to fifteen feet high.
Without devoting much time to the search I collected fifty species of Ferns in Borneo, and I have no doubt a good botanist would have obtained twice the number.

The interesting group of Orchids is very abundant, but, as is generally the case, nine-tenths of the species have small and inconspicuous flowers.

Among the exceptions are the fine Coelogynes, whose large clusters of yellow flowers ornament the gloomiest forests, and that most extraordinary plant, Vanda Lowii, which last is particularly abundant near some hot springs at the foot of the Penin-jauh Mountain.

It grows on the lower branches of trees, and its strange pendant flower-spires often hang down so as almost to reach the ground.
