| This genus constitutes the transition from the- re to 
the more aberrant groups of the Labiatiflore. The habit and 
the general resemblance of its flowers to those of the former 
family, justify the place which I have assigned to it. I have 
followed Lagasca and DeCandolle in restoring the old name 
of T'riris, first applied to designate the original species of this 
genus >A Dr. INN DNE: m the m — ee eme 
may Pope be ebkord goes distinct fet nstit nt 
another genus ; but this point I shall leave till further observa- 
tions shall determine. : |
