XOTES OX DIPTEROCAKPS.

Shorea parvifoUa, Dyer, has a subglobose capsule: and the 

 embryo has unequal cotyledons, the outer by a little shutting out 

 the placentar cotyledon from the apex of the fruit cavity. The 

 seedling is small in comparison with that of other Shoreas. 



Twin seeds were found. 



Shorea scutulata, King, has a capsule slightly elongated, the 

 outer cotyledon just shutting the placentar cotyledon out from the 

 apex of the fruit-cavity : these cotyledons appear almost equal after 

 o-ermination.

Illustrations of Shorea Curtisii, King, follow. It is a species 

 \ ery common on the hills of Penang and rather variable in the shape 

 and size of the fruit as well as in the length and breadth of the 

 calyx-wings, so much so that ultimately several varieties are likely 

 to be distinguished, the fruits of two of which are figured here 

 (figures 165 and 170). Both are represented among the specimens 

 cited by Sir George King in describing the species, so that both 

 are his Shorea Curtisii.

 placentar cotyledon small. All f nat. size.
