68. POLEMOlSriUM FAMILY. Order POLEMONIACEJE. 

 Herbs, not twining (but Cobasa climlts by tendrils), with regular flowers, all the parts in 

 fives, except the pistil, which is S-celled and the style 3-cleft at the top, the 5 sjjreading 



lobes of the corolla convolute in the bud, 

 i. e. overlapping so that one edge of each 

 is outside of that behind it, but inside 

 of the next one. Flowers generally 

 handsome. All the kinds here given 

 are cultivated ; but the Phloxes are wild 

 in this country (especially W. and S.), 

 and so is one Polemonium. (lilias are 

 prcttj' garden annuals from California, 

 &c. Cobaea, which is placed here, though 

 very different from the rest, is a great- 

 flowered vine from Mexico.
