412 LABIATjE. [part II. 



The stamens also differ. In most of the genera 

 there are four, but in Pentstemon there is a 

 fifth, long and slender, and hairy at the point, 

 but without any anther ; and in Calceolaria and 

 Veronica there are only two. Among the ge- 

 nera included in this order may be mentioned 

 Buddlea, the flowers of which grow in ball-like 

 heads ; Paulownia, Maurandya, ^limulus, Alon- 

 soa, and Collinsia. The Toadflax (Linaria), and 

 several other British plants belong to it ; but the 

 Yellow Rattle {Rhinanthus)^ and some other 

 allied plants, have been formed into a new order 

 called Rhinanthacese ; Chelone and Pentstemon 

 have been formed into an order called Chelona- 

 cese ; and Sibthorpia, Disandra, &c., into one 

 called Sibthorpiacese. Trevirana or Achimenes, 

 and Columnea, are removed to Gesneriacese. 



The new order Cyrtandracese, including Ms- 

 chynanthus, Streptocarpus or Didymocarpus, 

 Fieldia, and A mphicoma, is introduced here : 

 the first and last of these genera are new, and 

 the others were formerly included in Bigno- 

 niacese. • 



ORDER CXLII.— LABIATE. 

 The plants belonging to this order include 

 Mint, Sage, Thyme, and other kitchen aromatic 

 plants, and several well-known British weeds.
