ODOURS OF FLOWERS 89 
indica, Centaurea Cyanus; and to the latter Vitis vinifera, Reseda odorata, &c. On 
the other hand, cases are not rare in which bright colouring is associated with strong 
odour, as in many roses, syringas, pinks, stocks, and generally in many cultivated 
plants that for this very reason are grown in gardens. 
Delpino in 1873 (‘Ult.oss.,’ Atti Soc. ital. sc. nat., Milano, xvi, 1874) attempted a 
Classification of the odours of flowers. He distinguished two great groups, the Sym- 
pathic and the Ldiopathic, which he arranged in five classes according to the following 
scheme :— 
Classes of 
Sympathic. Idiopathic.

Delpino describes as sympathic odours, those that are more or less agreeable to 
a large number of insects (bees, wasps, flies, beetles) and also to man. He applies 
the term zdzopathic to odours that are sympathic to only a few animals, but that on 
the contrary are antipathic to a large number.
