biana Steph., a large and striking species, being the most notice- 

 able, are common on the paths and upon the ground wherever it 

 is undisturbed, and two species oi Marchaniia, M. geviinata Rein., 

 Bl. & Nees and M. ejuargiimta Rein., Bl. & Nees, are very abun- 

 dant. Perhaps the most striking of the ground liverworts of 

 Buitenzorg is Diiniortiera vehitina Schiffn., which is closely related 

 to D. tricJiocephala (Hook.) Nees of the more elevated regions, 

 and seems to take its place in the hotter lowlands. Of the thallose 

 Jungermanniales, the most conspicuous form about Buitenzorg is 

 Pallavicviia indica Schiffn., allied to the widespread P. Lyellii, but 

 considered by Schiffner to be quite distinct. Metzgeria Lindbergii 

 Schiffn. was not uncommon on the trunks of trees in some parts 

 of the gardens and seems widespread through the lower eleva- 

 tions. A large Riccardia [Aiicnrd), R. viridissima Schiffn. was 

 also not uncommon. No collection of the leafy liverworts was 

 made in Buitenzorg, but these are abundant upon the trees every- 

 where in the deep shade of plantations. Several species of An- 

 tlwccros are very common, growing upon the ground everywhere, 

 but these have not yet been identified. A Nototliylas, probably 

 N. javanic2LS Nees, is also not rare, but no specimens of Dendi-o- 

 ceros were collected about Buitenzorg. The latter, growing as it 

 does in masses of mosses and liverworts, is difficult to find and it 

 is not unlikely that more careful search would have brought it 

 to light. 



By far the most interesting collecting ground near Buitenzorg 

 is the region about the foot of the Salak. Here in the dense 

 forest and along the walls of the wild gorge of the Tjiapus there 

 is a wonderful growth of liverworts in great variety. Of the 

 forms quite new to me, the most conspicuous was the very strik- 

 ing Cyntlwdiinn foetidissimuni Schiffn. This grows in little cav- 

 erns and upon densely shaded rocks, and owing to some peculiarity 

 of the cell- structure the light is reflected from the large chro- 

 matophores so that the plant gleams with a vivid emerald light. 

 When handled it emits a very pungent odor like creosote, 

 which clings to the hands tenaciously. The most interesting find 

 was a lot of an Antlioceros which proved on examination to have 

 multiple chromatophores, like a fragment which I collected some
