INDEX. 



The first figures after the names of the orders refer to the numbers in the table under 

 which the names occur. 



The numbers after "sp." indicate the number of species of the order as given for 

 dicotyledonous plants, and some monocotyledonous, in De Candolle's Prodromns- for 

 monocotyledonous plants in Kunth's Enumeratio; for Filices in Hooker and Baker's Syn- 

 opsis Filicum; for Musci in Muller's Synopsis; for fresh water Alg* in Rabenhorst's 

 Algas Aqua Dulcis; for Floridoa and Fucoidese in Agardh's Species; for Lichens in 

 Nylander's Lichenes; for Fungi in Cooke's works and Fries' Hymenomycetes. Of course 

 these numbers do not accurately express the whole number of species known.
