only from this mountain. The monotypic Wiesnerella javanica 

 Schififn., also known only from this immediate neighborhood, 

 grew in large masses. This is a Marchantiaceous form evidently 

 allied to Dinnortiera, but having air-chambers and stomata like 

 those of the typical Marchantiaceae. Some remarkable hot 

 springs, Tjipanas, occur on the way up, and the hot steam has 

 caused an extraordinary development of vegetation. Where the 

 hot water oozed out of the hillside thick cushions of Sphagmivi 

 and other mosses and liverworts grew about the springs. 

 Among the liverworts growing here was Pallavicinia radicidosa 

 (Sande Lac.) Schiffn., which was some six inches or more in 

 length. A couple of days were spent at Kandang Badak, a 

 saddle between the two cones of the mountain. At this place, 

 which lies at an altitude of about twenty-five hundred meters, a 

 substantial shelter hut has been built and one can camp out very 

 comfortably here for as long as one wishes. At the higher ele- 

 vations the hepatic flora is not so well developed as further down, 

 but mosses and lichens are more abundant. Some species of 

 liverworts, however, are confined to this higher elevation. Of 

 these alpine Hepaticae, the beautiful Pallavichiia Zollingei'i 

 Gottsche is the most striking. This is one of the section, Mit- 

 tenia, with creeping rhizomes and upright fan-shaped dichoto- 

 mously branched laminae looking like Httle fern leaves. This 

 beautiful hepatic was common from a height of about twenty-two 

 hundred meters up nearly to the summit of Pangerango, the 

 highest of the two peaks. Pangerango is a very perfect extinct 

 cone, and seems to have a heavier rainfall than the neighboring 

 active crater of Gedeh. Another rare liverwort collected on 

 Pangerango was Fimbriaria Zollinger'i Steph. 



On the return to Tjibodas, a very large and conspicuous Dcn- 

 droceros was collected. The occurrence of this genus at such an 

 elevation (about 2,200 meters) was quite unexpected. This prob- 

 ably is an undescribed species, but no authentic specimens of D. 

 javanicus, the only species hitherto recorded from Java, were 

 available for comparison. A second, much smaller species was 

 afterward collected at Tjibodas, but which if either of these is the 

 true D. javanicus remains to be seen.
