MYOSURUS 7 



the Species Plantarum by Linnaeus. In the second edition of the same work 

 he described as separate species A. autumnalis, and A. aestivalis, ^hich. were 

 united in the A. annua of the preceding edition, but the name A. annua 

 should have been retained for the former species. In accordance with the 

 laws of nomenclature it is therefore used here ; it has also the advantage 

 of being more correct, since A. annua is a summer-flowering plant.
