The examination of the specimens of S 1 o a n e a j a v a n i c a 

 found in tlie forest of Depok, have shown me that the specific 

 description and fignre, published b}- M 1 q u e 1, is in the main, 

 correct, but requires ampiificalion and, with regard to a few points, 

 also correction. 



I confine myself here entirely to my observations on the material 

 from Depok (Herb. Kds. n. 42807 /?, 42814 /i, 42778 /?, etc.): 



Tree attaining a height up to 25 metres. T r u n k up to f metre 

 in diameter, fairly straight and sometimes columnar, with large 

 plank-buttresses formed by the roots, branching irregularly and 

 only high above the gi'ound. Crown high, dense, irregular. 

 Bark externally dark grey, with watery sap (no latex and no 

 resin). Leaves with dark gicen upper surface, lower surface 

 bluish green; smooth and shiny on i)Olh sides. The leaves of very 

 young plants, only 2 metres high, may attain a length of 40 centi- 

 metres, but those of the fertile branches of a very old tree, 25 

 metres high, are only 10 — 20 ceiilimetres long. Young twigs pale 

 green ; older branches dark grey (not brown). 



Fruits (ripe, but not yet dehisced): externally a beautiful orange 

 (not brick red). Mesocarp thick, woody, dry, grey, almcst tasteless 

 and odourless. Endocarp thin, of a beautiful purple colour. Seeds 

 (ripe) almost completely envelo|)ed by a fine orange yellow or orange 

 (not red), glistening, almost odourless and very bitter arillus. Testa 

 externally shiny black, crustaceous (not osseous). Endosperm small, opal- 

 white, fleshy. Embryo large, pure white, odourless, of pleasant taste.
