A trip fioni Djokjakarta via Wonosari, Kei-nadang, Djepitu 

 and Kalak to Patjitaii and froiii there via Tulahan and Tegalombo 

 t<) Bilung was made in order to investigate the flora of this 

 paît of tliL' Duizendgebergte. Again a trip strongly to ho recom- 

 mended. None of the primeval forests, Janghulm speaks of^ seems 

 to he left, the hills are covered with hoemas and alangfields, 

 in the vaheys are many sawah's. Near the sea small seciindary 

 woods were met with. On the steep slopes of narnerous hills 

 many remnants of the original flora could be found, Chirita 

 coerulea and Rhy ncoglossu m are very common. N"ot only 

 on the hills but also on waste hoemas and fallow-lying sawah's 

 many interesting plants were gathered. 



One excursion was made to Mount Tjerimai, which up to 

 its very summit is covered with a dense végétation extending 

 even to the inner side of the gigantic crater. The rhinocerospath 

 around the latter which Junghuhn mentions, has almost entirely 

 disappeared. This excursion enabled us to establish the identity 

 of the puzzling Zizyphora javanica Bl. which proved to be 

 no other plant than the common Satureia umbrosa Scheele. 

 See the list at the end of this bulletin sub voce Zizyphora. 



Two excursions were made to the immense Rawah Lakbok and 

 its sui'roundings. The centre of the 'rawah is for miles at a stretch 

 overgro wn with P h r a g m i t e s K a r k a. The margins are covered 

 with a mixed forest in which Klein ho via hospita is very 

 common, also species of Gala m us (especially C. horrens) 

 which often prove a serions impediment to the traveller. in the 

 southern part bogs are tu be found. The calcareous hills which 

 arise in the rawah are partly covered with primeval forests. 

 Many interesting plants were found hère. 



An excursion to Pelabuan Ratu and Tji Letuh proved that 

 primeval forests in thèse régions are not so common as was 

 supposed. Secundary forests are very fréquent. The flora of 

 Tji Letuh differs very much of that of Pelabuan Ratu. At Tji 

 Letuh I found among many other rare plants also the beautiful 

 Exacum mentioned by Junghuhn. 



A trip to the eastern slopes of Mount Gedeh clearly shovved 

 the great inthience of water on the character of the flora. The 

 flora of the dry eastern slopes is amazingly poorer than that of 

 the western ones, wliere water abounds. The flora of the celé-
