As figure 49 shows, the seedling bears a pair of leaves, follow- 

 ed by closely approximated alternate leaves, much after the manner 

 of Dryobalanops aromatica, only that they are distinctly alternate. 

 In its wiriness it is also similar. 



The seedling develops a small amount of red pigment. 



Hopea mengarawan, Miq. from Singapore island, but little 

 distinct from the last, is represented in figure 54, and a section 

 through its embryo in figure 55. This section shows that the coty- 

 ledons are rather thin and that the outer goes far towards envelop- 

 ing the inner. The name " H. mengarawan " is used as Mt. Eidley 

 has used it: MiquePs type has not been compared.

The reader will observe that the similarity of the Hopeas of 

 the section Dryobalan aides to the genus Dryobalanops as seen in 

 the mature foliage, is repeated in certain characters of. the seedling. 



Balaxocaepus (excluding Eichetia). 



Balanocarpus Curtisii, King, will be described next. It is a 

 common small tree of some parts of Penang island. 



As in the genus Dipt ero carpus, the flowers face earthwards; 

 but they are small, and illustrate the statement that greater 

 size and downward direction in anthesis do not accompany each 

 other through the order. They are claret in colour, with petals 

 but little twisted.
