 Mauritius. Pal. de Beauvois. — Schrader appears to us to be 

 not far from the truth in describing superficial leaves or sti- 

 pules to this plant. The lower leaves are larger and distichous, 

 the upper or smaller ones more or less imbricated, and generally 

 curved upvi^ards. The denticulation of the scales varies 

 both in American and Indian specimens.

 been unable to detect any essential difference between L. com- 

 planatiim and L. tristachyon. The number of the spikes is 

 exceedingly variable, as is the whole plant in regard to size 

 and degree of ramification. L. thyoides of Humboldt, too, 

 has all the appearance of L. complanatum fi'om a warmer part 



* This little groupe, although not proposed by any preceding author, appears 

 to us to be an extremely natural one. Stipules are present, and the leaves are 

 bifarious and distichous, as in the Stachygynandra ; but here the leaves and com- 

 pressed branches are combined, and form, as it were, but one substance. The 

 stipules are in one series, sometimes on the upper as well as ou the under side, 

 the former being rarely tvanting.
