Ferns are prominent among the flora, about one-third of which consists of endemic species.
The spores differ from those of ferns in their outer coat (exospore) being split up into four club-shaped hygroscopic threads (elaters) which are curled when moist, but become straightened when dry.
The soil to the depth of many feet, and from it springs the most marvellous tangle of huge trees, shrubs, bushes, underwood, creepers, climbing plants and trailing vines, the whole hung with ferns, mosses, and parasitic growths, and bound together by rattans and huge rope-like trailers.
The vegetation is almost tropically luxuriant - palms, wild pineapples, and ferns growing profusely, and the valleys being filled with wild beans and patches of taro.
