458 DOUBLE FLOWERS. 



Sydney Goodenia heterophylla (Sm.) has been noticed in the same 

 fasciated state. It is clear, therefore, that deviations from their 

 typical character in flowers are not always due to cultivation, and 

 that, in all probability, insects play an important part in the 

 matter. The subject is one of interest to the Florist, and I may 

 add to the Entomologist, for, as the late Mr. W. S. Macleay used 

 to say " the affinities of plants may sometimes be traced by the 

 presence of particular insects"; whilst it may fairly be assumed 

 that the development of double flowers, as the result of hybridi- 

 zation and some other caixse, points in a similar direction, viz., the 

 agency of insects. My object in offering these remarks is to direct 

 the attention of collectors to the abnormal growth in flowers, as 

 they are sometimes seen in their native state. Persons engaged in 

 collecting search only for perfect specimens and pass over any that 

 deviate much from their types. These deviations, however, are not 

 devoid of interest, and a greater knowledge of them may lead to a 

 better understanding of the anomalies to which I have referred.
