NOTES OX DIPTEROCARPS. 69 



Shorea pauciflora, Dyer, has a large fruit very like that of S. 

 costata, but a trifle greater in length. The embryo seen with the 

 radicle away from the observer is drawn in figure 135. The seedl- 

 ing produced is relatively large, so that with practise it can be 

 detected by eye among the seedlings of other species. The coty- 

 ledons are as figured below (figures 136. 137, 138 and 139). The 

 groove in which the placenta lies is not quite so narrow as in some 

 other Shoreas. 



Figure 135, embryo of Shorea pauciflora with the radicle away from the 

 observer ; figure 136, the cotyledons cf Shorea pauciflora ; figure 137, the 

 outer cotyledon from the outside ; figure 138, from che inside ; figure 139, the 

 placentar cotyledon from the side toward the outer cotyledon ; figure 140, from 

 the other side. Figure 136-140 £ nat. size. 



Shorea pauciflora has a downwardly directed ureeolate flower, 

 which seems characteristic. 



Figure 141, a flower of Shorea pauciflora in face view and in vertica 

 section, x 2. 



Shorea utilis, King, is the subject of figures 142 to 148. The 

 fruit is rather short (figure 143) and the embryo has its placentar 

 cotyledon only just shut off from the apex of the fruit cavity.
