of many kinds. There are numerous species of Eugenia and 

 Litsea, three of Viburnum, two of Turpinia, and one each of 

 Euonymus (E. javanicus), Ilex (I. spicata), and 01 ea (0. java- 

 nica). The small tree Pithecolobium montanum is one of the 

 few Leguminosae to be found in these mountain forests. We 

 shall meet a second tree member of this family on the very 

 summit of Gedeh. Another tree 

 of this and the second subzone 

 which is worthy of special 

 note is Vernonia arbor ea. This 

 tree is one of the Compositae, 

 yet it may be 80 feet high 

 and 2 y 2 feet in diameter 

 (Fig. 4). 



The fig, Ficus Ribes, is an 

 interesting small tree because 

 it affords a striking example 

 of a rather common fruiting 

 habit among tropical trees, 

 namely, cauliflory. Saurauja 

 (S. pendula, S. nudiflora, and 

 five other species), whose white 

 flowers with thick, waxy petals 

 are often seen strewn over the 

 path, is an example of incom- 

 plete cauliflory. The flowers 

 are borne not only on the sur- 

 face of the tree trunk and larger 

 limbs but at the tips of slender Fig. 4. The trunk of Vernonia 



twigs as well. Such a semi- arborea. This 80 foot tree is one of the 

 cauliflory characterizes several Compositae. 

 other Javanese trees. 



The foregoing list of first subzone trees is very incom- 

 plete and gives at best but a number of representative spe- 

 cies. Of trees alone there are nearly two hundred species on 

 Mt. Gedeh; of shrubs and herbs over three hundred and fifty 

 species; and of lianes some sixty or more, totaling at least six 

 hundred species of plants exclusive of the ferns, mosses and fungi. 



Lianes are numerous in the first subzone. The family 

 Vitaceae is well represented among the smaller climbers
