E. globulus (Blue Gum) flowers every year and so does 

 Eucryphia Billardieri (Pinkwood). Mr. Andrew Murphy, 

 a seed collector in New South Wales told me that Ango- 

 phora lanceolata (Smooth-barked Apple), Eucalyptus 

 corymbosa (Bloodwood) and Eucalyptus tereticomis var. 

 dealbata (a Red Gum), and E. diverslcolor (the West 

 Australian Karri) all flower every other year. In the 

 Report of the Royal Commission of Enquiry in Forestry 

 (N.S.W.) 1908, at Part ii, p. 607, Mr. William Ager, bee- 

 farmer of Grafton, gives useful information in regard to 

 the flowering period of the native trees, which is the more 

 valuable since we have so few data. 



(3) They furnish data for hybridisation observations, 

 whether artificial, or the natural processes which go on in 

 the bush, e.g., such as have been fully proved in regard to 

 the genus Eucalyptus. 



(4) They furnish data for ringbarkers, as flowering periods 

 are especially suitable for ringbarking operations. 



(5) They furnish data in regard to meteorological con- 

 ditions, and we want as many useful methods of tackling 

 meteorological questions in this climatically difficult con- 

 tinent, as it is possible to contrive. 



(6) They are important in connection with the collection 

 of native seeds — an important Australian industry. 



(7) They indicate proper times for Field Naturalists' 

 excursions to visit specific localities. 



(8) In fine, the advantage of accustoming people to the 

 systematic making of observations in Natural History 

 cannot be fully ascertained. 



Tentative Selection of Plants for Phenological 



Observations. 

 In Britain the selection of plants for phenological obser- 

 vations is comparatively easy, firstly, because the vast
