 Menthaceae. Mint family. 



This family is represented in Guam by the genera Coleus, ^Mentha, Mesosphaerum, 

 and Ocimum. The author of the name ilenthaceae, which is here pubhshed for 

 the first time, is Prof. Lester F. Ward, who has presented the following statement 

 regarding it: 



' ' Permit me to propose the name Menthaceae for the mint family as the most suit- 

 able substitute for the name Labiatae, given it by Bernard Jussieu in Hort. Trianon, 

 17.59, and used by most botanists since that date, but which has not the proper ter- 

 mination and is not formed from the name of any genus of the family. Being based 

 on Mentha, the most typical genus of the family, it has better claims, except in the 

 matter of priority, than Lamiaceae (Lindley, 1836), >'epetaceae (Horaninow, 1843), 

 or Salviaceae (Drude, 1879)."
