4. Pliaeiiological observations. 



I have tried as far as possible to settle at what time of tlie year the different 

 Falkland plants flower and ripen their seeds. S. Birger (1) gave an accoimt of 

 lus notes on the subject, but his observations only extend över the last weeks in 

 February; thus, they were made in the autumn and, fiirther, do not at all comprise all 

 species. Låter I made some fragmentary remarks, which, however, have proved 

 useful to complete my notes from the second expedition. In the following list I 

 have not given the exact date, wlien a certain stage was noticed. The reason for 

 this is that my observations on a certain plant were made in many places all över 

 the Islands, and there may, of coiirse, be small differences in the development of 

 the flowers of the same species in different localities. Therefore I have only put 

 down if the state of flowering referred to was observed in the beginning (b.), middle 

 of (m.) or at the and (e.) of the month. Exceptions from the rule are specially noted.
