THE PEPPERWORT TRIBE. 



Creeping plants, by Lindl. referred to 2 genera, both of which are in- 

 habitants of ditches or inundated places, in various parts of the world. 

 They do not appear to be affected by climate so much as by situation, 

 whence they have been detected in various parts of Europe, Asia, Africa, 

 America and New Holland, chiefly, however, in temperate latitudes. Pro., 

 perties unknown. {Lindl.) One of the genera, Pilularia, contains but a 

 single species: P. globulifera, L. ; E. B. 8, t. 521. The other, Mar- 

 silea, has several representatives. In India there appear, according to 

 Royle, to be three distinct species : M. (egyptiaca, Willd., which is found 

 in the Peninsula of India, as well as in Egypt, and which appears to be 

 M. erosa, Willd. ; — M. coromandelina, N. L. Burm, ; (M. minuta, Lam.) 

 a species apparently peculiar to the most southern part of the Indian Pe- 

 ninsula ; and

Floating plants with rooting stems, by Lindl. referred to 2 genera. Of 

 Azolla, I species has been found in S. America, down even to the Straits 

 of Magellan ; 1 in Portorico ; 1 in Carolina and Canada ; 2 in New Hol- 

 land and Van Diemen's Land, and 1 to the eastward of Bengal, and in 

 Behar. The latter, according to Royle, appears to he nearly allied to, if 

 not identical with, A. pinnata, R. Br. The second genus, Salviaia, has
