When we have made a provisional list of well-known plants, we have still to 
remember that they should be arranged, as far as possible, under the months of flowering, 
in order that as March comes round, for example the observer may be on the look-out 
for specific plants. Now this arrangement, with our irregular flowering seasons, due, 
in part, to our continental climate, presents real difficulties. For example, I turn to 
the herbarium and see Eucalyptus paniculata, the Grey Ironbark, collected in flower 
in eight months of the year, viz., November to February, and June to September. I 
should not be surprised if it flowers in other months as well. Of course, it does not 
flower in all these months every year. Again, turning to Tallow Wood, Eucalyptus 
microcorys, I see it flowers in July, and from September to December. Some plants, 
as the Native Rose, Boronia serrulata, have, however, a very limited flowering period 
in winter and spring, as everyone knows. It is, therefore, difficult to construct a floral 
calendar at this stage, but if I invite attention to the matter and secure the co-operation 
of a large number of observers, I am sure that in a few years many of the difficulties 
of making a list of plants in flower during certain months will disappear. 
In going through a large herbarium it would be useful to take notes of the dates 
of flowering (with locality and date) of each species, particularly noting the earliest 
and latest days. It does not follow that the flowering dates as represented in the 
herbarium, being of specimens collected for a different object, will be of paramount 
importance for phonological observations, but they will certainly valuably supplement 
information collected in front of plants with a phenological end in view. 
Bibliography non-Australian. 
In the International Catalogue of Scientific Literature (Botany), Phenology is 
assigned the sequential number 3,800, under the division Physiology. In each volume, 
beginning with the first (1902), we have a list of papers and larger works in various 
languages on the subject, and it is not necessary to recapitulate them at this place. 
A few, mostly earlier, references will, however, be given presently. 
Leaving aside the strict meaning of the term, Phenology includes such papers as, 
" Flowers on Christmas Day," and all kinds of observations in regard to the obvious 
appearance of the various organs of plants. 
I have no doubt that, apart from the inherent value of the records themselves, 
they will lead to the provision of data for a botanical survey of individual States and
