Erect shrub or small tree, from West- to East-Java 

 occurring here and there on sandy or rocky beaches, always 

 in scattered specimens. It has also been found in the interior 

 but it is possible that these specimens were cultivated ones 

 or the offspring of these. The reproduction is effected 

 exclusively by seeds. The pods do not burst when the 

 seeds are ripe but fall off as a whole; they possess floating 

 power. 



Some scattered specimens.

Several specimens. 



15. Pongamia pinnata Merr. (P. glabra Vent.). 



Medium-sized tree, spread from West- to East-Java on 

 sandy or rocky coasts, especially occurring in the Barringtonia- 

 formation and there often frequent. The rather thick, coria- 

 ceous, indehiscent pods ') contain a single seed, not entirely 

 filling up the fruit-cavity; they possess floating power and 

 are often washed ashore. 



Some scattered specimens. 



16. Erythrina varicgata /.. var. orientals Merr. (E. indica Lmk.) 



See p. 46, sub No. I. 



Here and there on the beach. 



17. Canava/ia rosea D. C. (In Ernst's paper named C. 

 obtusifolia D. C.). See p. 89 and p. 92, No. 8. 



In many places on the beach. By some mistake Ernst 2 ) 

 mentions this creeper among the twiners which formed a ,,fast 

 liickenlose Laubwand" with young Casuarinas and shrubs. 

 Incorrect is likewise Ernst's statement a ) that this species 

 together with other plants, formed ,,formliche Dickichte" 

 along the borders of the gullies of the interior. 



18. Vigna marina Merr. (V. lutea Bth. and V. luteola Bth.). See 



pp. 89 and 93. 



In many places creeping over the beach and twining in

 Caesd/p;V)/'a crista L. (in E r n s t 's paper C. bonducella) is also recorded and likewise 

 wrongly so, for though a climber it is no twiner and as Ernst rightly observed on p. 39 

 this species was not found in 1906. It is not mentioned for Krakatao in the list of 

 finds given by Ernst (p. 42), but nevertheless given for the interior on p. 55.
