NOTICE. 



As last year, the undersigned, intend to observe, as accurately 

 as possible, the most important stages of vegetation in certain 

 plants*, and invite the cooperation of naturalists. 



Observations are to be made on standards (excluding espaliers 

 and wall-p]ants), in normal situations, neither unduly exposed 

 nor sheltered ; and these observations should be made frequently, 

 daily if practicable. The earliest ripe fruit to be noted in soft 

 fruits \A^hen a complete and definite colouring of a single normal 

 fruit has taken place, and in capsular fruits vyhen the carpels 

 spontaneously open. 



Communications relative to the current year, as well as of 

 previous years, vs^ill be gratefully esteemed by either of the under- 

 signed. 



The dates before the names of the plants give the average for 

 Giessen, 525 English feet above the sea-level ; these dates may 

 casually occur also at other places. 



Communications to be addressed direct to Dr. H. HoFEMAifir, 

 or Dr. Egon Ihke, Griessen, Grermany. 



* The list of plants will be found on the preceding page.
