 of tree 92 (VI. (J.) indicates, that its lunnbered Hortns-iree was

Habit. In the fruiting season this forest giant with a trunk, more 

 than If metres in diameter, is very striking. The dark green crown 

 is then adorned by numerous fruits, almost as large as fisls, extern- 

 ally orange, internally a l)eautiful purjile and opening by four valves. 

 These generally contain 1 — 2, rai'ely 3 — 4 glisiening jet black, 

 oblong, fairly laige seeds, for the most part enveloped by an arillus 

 of a fine orange yellow colour. Except on account of the large 

 dimensions of the trunk, with the large plank-buttresses formed 

 by the roots, this tree is not very conspicuous outside the fruiting 

 season. Young trees easily escape Mie attention of the field botanist, 

 because ibis species, even in the sole original habitat so far kuown^ 

 i.e. in the forest of De|)ok. Duly occurs very scattered and does not 

 piodiice flowers and fruits until it has attained an advanced age; 

 a further reason wh}' young specimens are inconspicuous, is that 

 their leaves show such a close resemblance to those of some other 

 Javanese trees, as regards shape, size and innervation, (hat they are 

 only distinguished after close scrutinizig. The latter reasons explain 

 the fact that the o r i g i n a I habitat of S 1 o a n e a javanica 

 couhi ha\e reiiiaiiK'd unkimwii fui' nearly half a century, in spite 

 of its situation near a scientific centre like Buitenzorg, in the forest 

 of Depok, often visited by many botanists.
