NATURAL HISTORY OF PLANTS. 



possible. Some, as P. glaucescens of India, have caducous sepals ; ^ 

 others, as P- triphylla^ have sepals less unequal, and the stamens are 

 sometimes not more than six in number. It is on this account that 

 we may consider it as only a section of the genus Polt/gala^ the 8alo- 

 monias,^ small Asiatic herbaceous species, which have but slightly 

 unequal sepals, and four or, more rarely, five or six stamens. Some 

 species are parasites, discoloured, with squamiform leaves.^ 



Thus constituted, this genus contains about two hundred species,* 

 natives of all parts of the world, more abundant in warm and 



Muraltia Seisteria.
