The Report of Roure-Bertrand fils 1 ) of Grasse contains an 

 interesting work by Marin Molliard on "Menthe basilique'e". Under 

 this designation is understood a degeneration of the peppermint plant 

 frequently observed in the South of France, which shows itself in a 

 completely altered appearance as compared with the normal plant 2 ). 

 The change consists of this, that the stalks and twigs which normally 

 would run into inflorescences, never again form blossoms, but only 

 leaves closely bunched together. The large leaves at the base of 

 the altered twigs also show in their shape characteristic differences 

 from the normal leaves of the peppermint; they are, namely, contrary 

 to the latter, almost sessile, have a hand-shaped nervature, and a 

 scarcely dentated edge. The stalk of the altered plant, of which the 

 section is originally square, shows in the ramification a more and 

 more circular section. These morphological and anatomical changes 

 are caused, according to Molliard's researches, by a parasitism of 

 acarides belonging to the group phytoptides and the family eriophyes. 

 We would in this place only refer to the detailed description of the 

 parasite to which Molliard has given the name "Eriophyes menthae". 

 The acarides already attack the twigs of the peppermint plant at the 

 moment when they are just breaking through the earth. The outer 

 leaves undergo the least change, as they are soon left by the para- 

 sites, which endeavour to settle at the point of the newly forming 

 leaf-buds. The younger leaves, however, which have to develop 

 entirely in the presence of the parasites, suffer most from the de- 

 structive action of the acarides. 



Up to the middle of July the parasites are found in large numbers 

 on the twigs altered by them; they then disappear gradually. They 

 hibernate apparently in the earth close to the stem or on its surface,
