cbyma is clustered around a very large one, in whicli is found 

 a great deposit of apparently fine substance, described in 

 the former part of this paper. See Plate XXX. 



19. Bridelta exaltata, F.v.M. N.O. Euphorbiaceae. 



A fairly compact timber, the fibres of rather small 

 diameter, and pores also small. Crystals are fairly numer- 

 ous in the wood parenchyma. 



20. Mallotus philippinensis, F.v.M. N.O. Euphorbiacese. 

 A timber with quite an unusual structure, the wood 

 parenchyma being arranged in rows parallel to the rays and 

 fibres, the latter having an exceedingly small diameter. 

 The rays are of the multiseriate type, many of the larger 

 cells containing large crystals, in some cases smaller ones 

 were seen. It is the only instance in which a cell was 

 found to contain more than one crystal. 



21. Oasuarina torulosa, Ait. N.O. Casuarinese. 

 A close, compact wood, the fibres nearly always contain- 

 ing a brown deposit, as well as the vessels, which are thick 

 walled. The large multiseriate rays are a distinguishing 

 feature of this and all the Oasuarinas, except O. Cambctgei. 

 The wood parenchyma is fairly numerous and extends in 

 parallel narrow lines to the early and late growth, and 

 appears to be of two kinds, one without and one with a 

 deposit — amorphous and crystalline. 



22. Oasuarina glauca, Sieb. N.O. Casuarinese. 

 Crystals are fairly numerous in the wood parenchyma 

 and of rather large size, and are seen in the transverse, 

 radial and tangential sections, a very unusual circumstance.
