1. Mentha calliopsis Borbas, 1. c. p. 51. 



Laete viridis, sparse pilosa, nitens, folia ovata, basi rotundata, bre- 

 viter in petiolum angustata, inaequaliter majoribus minoribusque dentibus 

 -serrata. M. lamprosomae (p. 53) afflnis, dentibus foliorum apertis, verti- 

 cillastris spicato-confluentibus, inferne paucis remotis praecipue differt, 

 <lum in M. lawprosoma verticillastra plura a pseudospica remota sint 

 ideoque M. callioj'sis minus ac M. lamprosoma, a M. aquatica diversa est.
