nila, Pycnanthemiim (the whole seventeen species), an anom- 

 alous Satureia (^S. riglda, Bartr.), three species of INIicrome- 

 ria ; while to Calamintha is now referred the former 31. gla- 

 bella and 31. Nuttallii^ as well as the Gardoqida Hookevi^ 

 Benth., with the new C. canescens^ Torr and Gr., MSS., and 

 C. Caroliniaiia^ Sweet (Thymus, Michx.) ; also two species 

 of Dicerandra (of which D. densijlora is a new one from 

 Florida) ; the California Pogogyne ; Hedeoma, including 

 H. ciliata QKeithia ciliata, Benth., Lab.) ; and Collinsonia, 

 of which six species are recognized. 



Of the tribe 3Io7iardece we possess a small portion of the 

 vast genus Salvia, which is increased to 407 species ; Audi- 

 bertia of California, of six species ; Monarda, of six species 

 (J/, did y ma and 31. jistidosa being retained nearly as in the 

 earlier monograph) ; and Blephilia, of two species. 



The tribe Nepetece affords us Lophanthus ; a single Dra- 

 cocephalum ; and a Cedronella. 



The tribe StacJiydece furnishes Prunella, for which Al-

 shown in Chlor. Bor.-Amer., and not under B. truncata) ; 

 Macbridea and Synandra, each of a single species ; and 

 Stachys (from which Betonica is now excluded), of 168

Of the Ajugece we have Isanthus, Trichostemma (in which 

 a corrected view is taken of the inflorescence of the typical 

 section), and Teucrium. 



The small order, Selaginacece, contributed by Professor
