of the species show a great range of variation, and others certainly 

 distinct seem to be separated by comparatively trivial characters, it is 

 hoped that such cases are here so grouped that the ultimate solution of 

 their relationships will be facilitated. 



From the following table intended to show the distribution of the 

 species of this family in this and the nearer geographical divisions, it 

 will be apparent at a glance that the genera found in the Philippines 

 are for the most part typical in the Old World of the Indo-Malay region, 

 the other extensions being chiefly Australian. Various genera, wrongly 

 credited to the Philippines, are here excluded. In Australia, numerous 

 other genera are found. The Formosan comparison is interesting, as a 

 floristic classification, now much in favor, constitutes that island and the 

 Philippines into a single sub-province. 



Cultivated species have in all cases been excluded, with the exception 

 of Psidium and two or three species of Eugenia, whose present distribu- 

 tion is such that it is difficult to pronounce an exact opinion on this 

 point. Psidium guajava is now so widely spread in the Philippines, 

 outside of cultivation, that it can not be excluded.

Among the undetermined material, one sheet, For. Bur. 1880 Curran, 

 from Mount Pulgar, Palawan, may represent a genus as yet undescribed : 

 it is in flower with merely strong probabilities as to the nature of the 

 fruit, and the ovules are quite immature. It is possible that other
