To which of the groups of Comus sanguinea L. (C. foemina 

 Theophrastus) or Comus tikis L. {Comus mascida Theophrastus) the 

 generic name Comus should be retained is a disputable question. If 

 Latin-name Comus (not translated from Greek) published for the first 

 time represents the Comus, Comus in Plinius, Naturalis Historian liber 

 15 caput 41 (1469) would be the real Comus, and we call it now 

 Comus sanguinea. But, the genus Comus was at first founded by 

 Tournefort in his ' Institutio rei Herbarite I. p. 641,' in which he 

 also included both Comus mas and Comus sanguinea. For the groups 

 of Linnaean Comus, there were already generic names; for instance, 

 Chamaepcriclymenum, Euhrania (partly) and Arctocrania for Comus 

 suecica and Comus canadensis (including var unalaschkensis) ; 

 Cynoxylon for Comus florida ; Svjda for Comus sanguinea ; Euhrania 

 (partly) and Macrocarpium for Comus mas. Although Rafinesque 

 made Euhrania basing on Comus mas, Comus canadensis and Comus 

 suecica, he took Comus mas for the type. But, unfortunately, his 

 generic descriptions do not given any characteristics of Comus mas. 

 His type, therefore, has no systematic value, and Euhsania looses its 

 A T alidity. I shall still use Macrocarpium for Comus mas as I published
