Euphorbiaceae. 



24. Macaranga tanarius M. A. See p. 135, No. 26. 



Scattered on the lower slopes. Not rare in the ravine- 

 forest. 



25. Homalanthus populnea O. A'. 



Small tree, spread throughout Java between 100 and 1800 

 m. above sea-level, especially in the western part of the 

 island. It grows in sunny or slightly shadowed localities, in 

 forest-glades and on forest-borders, on ravine-sides, in se- 

 condary forests and in jungles, frequently on water-sides, 

 often in great numbers. The reproduction is effected by the 

 seeds which are copiously produced and are dispersed i.a. 

 by water. Though it seems not yet to have been observed 

 they are possibly also spread by animals; if not, the occur- 

 rence of the tree far from water could hardly be explained, 

 as the seeds are too heavy to be carried by the wind over 

 a distance worth mentioning. 



Here and there in the ravine-forest upwards of 200 m. 

 above sea-level. 



Vitaceae. 



26. Columella tri folia A/err. See p. 136, No. 28. 



Several specimens somewhat behind the beach. 



27. Z.ee<j indicti Merr. 



Erect shrub or small tree spread throughout Java in the 

 plains and in the lower mountainous zone, as well in regions 

 where the east-monsoon is strong as where it is feeble, in 

 thickets and secondary and primeval forests. The repro- 

 duction is effected by the berries which are produced in 

 great numbers. It is unknown in which manner these are 

 dispersed. 



Here and there scattered in the ravine-forest above an 

 altitude of 100 m. 



Sterculiaceae. 



28. Melochia umbellata Stapf. See p. 117, No. 51. 



Scattered specimens immediately behind the littoral vege- 

 tation and here and there in the S<3cc/)arum-jungle.
