ten years ago in Jamaica but had not found since. As this was 

 one of the forms I was especially looking for, its discovery was 

 the event of this interesting expedition. This has since been 

 made the type of a new genus, Megaceros. Another undescribed 

 species of the same type was found afterward in the more ele- 

 vated region about Tjibodas. 



Lying on the slope of the magnificent volcanic mass Gedeh, is 

 the mountain station Tjibodas, a dependence of the great garden 

 at Buitenzorg. Tjibodas comprises a garden where are grown 

 many plants of temperate and subtropical regions, and includes a 

 laboratory with living accommodations for four persons. The 

 elevation of the garden is about fourteen hundred meters and I 

 found the temperature almost cooler than I liked after the hot- 

 house temperature of Buitenzorg. The thermometer seldom 

 rises above 20° C. and as it is apt to be 'io^gy and rainy, it is 

 often decidedly chilly, especially in the morning and evening. 

 But in this cool moist atmosphere liverworts revel and I have 

 never seen anything to approach the hepatic flora of this mountain. 



From the garden up to the summit of the highest peak, Pan- 

 gerango, which is ten thousand feet high, is an unbroken primeval 

 forest of wonderful beauty, and overflowing with botanical treas- 

 ures of every description. For a long distance beyond the gar- 

 den, which abuts directly upon the forest, a series of paths have 

 been cut through the forest, and these are numbered so that one 

 runs little danger of getting lost in the dense jungle, which 

 without such paths would be quite impenetrable. Many of the 

 finest trees are labeled and several thousand of them are num- 

 bered. Otherwise the forest has been untouched. 



The paths in the garden and the sides of the banks were often 

 densely overgrown with masses of Marchantia and AntJioceros 

 of several species. Of the former the most conspicuous was 

 M. nitida Lehm. & Lindenb., a large light-green species growing 

 in extensive mats. Several others also occurred. 



It was in the forest, however, that the great majority of the 

 forms grew. I naturally was anxious to collect Trciibia and 

 found that the native collector Sapihin was well acquainted with 

 this ; so very soon after my arrival at Tjibodas we started out in
