LEGUMINOSJE. 



(FABACEjE, Lindl.) 



In the analysis of the genera of this order made by Dr. 

 Lindley, the distinctions upon which the principal divisions 

 (Loteo? and Video?) are founded consist in the cotyledons ris- 

 ing above, r or remaining beneath the ground during germina- 

 tion. To determine, however, which of these two conditions 

 obtains, is frequently rendered very difficult from the rarity 

 of specimens, or from their not being met with during the ear- 

 lier stages of development ; I have therefore been induced to 

 construct the following table, without reference to the above- 

 mentioned divisional characters adopted by Dr. Lindley. 



The British genera of Leguminosw are contained within 

 the Linnaean division Diadelphia Decandria.
