But its beautiful green did not long refresh our eyes, for it soon dis- 

 appeared, and species of oaks, especially Qu. pruinosa, BL, began to 

 predominate in the woods. These are immense trees, 100 feet high, 

 whose branches are thickly covered up to the highest tops with succu- 

 lent parasites, OrchidecE, mosses, Usnece, and numerous other lichens. 

 The whitish Usnece hang down many feet long from the branches. In 

 company with the oaks we find the Areca humilis, W., a palm with 

 slender stems scarcely as thick as an arm, whose red bunches of 

 fruit adorn the steep acclivities. Here were seen on every side the 

 beautiful umbrella- shaped, palm-like foliage of the tree-ferns upon a 

 little stem 30 feet high, which grow at this elevation most luxuriantly 

 {Chnoophora glauca, BL). 



The oaks gradually become less frequent, and another kind of tree, 

 Kaju-Angring (a species of Celtis), by degrees becomes more and more 

 predominant, and at last exclusively constitutes the woods. These 

 are trees of a moderate height, with gray slender stems and slender 

 branches, which are only partially clothed with scanty foliage. With 

 these occur species of Ruhus, whose red berries reminded us agreeably 

 of Germany and our own Hartz forests. The mists became thicker 

 and the cold more piercing (60° F., 12° R.), and the rocky clefts 

 thickly overgrown with weeds became more frightful. In one of 

 these clefts we met with a cavern (rather a fissure in the rock) in 

 which species oiRubus (^R.javanicus, BL, R. lineatus, R. moluccanus, 

 L.) grew most luxuriantly ; we here noticed the last stems of the 

 Musa paradisiaca, which up to the present time had accompanied 

 us. The steepness of the acclivities, the rocks of which rise in steps, 

 increased. The angring-trees became lower, and their stems more 

 thin and slender ; but the Usnem, which hang down from their 

 branches, were more frequent. Here began to appear a small fern 

 (Polypodium vulcanicum*), and higher up it became more numerous. 

 It grew luxuriantly from the crevices of the boulders of rock, which, 

 cemented by a softer earth, cover the ground f. The luxuriant climb- 

 ing plants and tropical shrubs had now disappeared ; but plants suc- 

 ceeded which reminded us more of the flora of the temperate climate 

 of Europe, especially bushes of red-berried species of Rubus, and the 

 Hypericumjavanicum, BL, a shrub covered with yellow blossoms. 



We now arrived, all the while enveloped in thick mists, at a rocky 

 headland overgrown with the before- mentioned ferns and with grass ; 

 here blackish gray masses of trachyte of very various sizes projected 

 from the soil, and many little channels descended straight down the 

 mountain's side four feet broad and four to six feetdeep. It was already 

 3 o'clock ; I doubted of being able to reach the top of the mountain 

 that day, especially as the Javanese had lain down and lighted some 

 fires, for which the dry leafless branches of the angring-trees yielded

t It is peculiar to all the high mountains in Java, and characterizes all 

 acclivities situated at above 5000 feet, covered with boulders of rock : I found 

 it at a later time, just as plentiful as upon the Merapi, on the mountains in 

 Cheeribon and in the Preangerlanden (West Java).
