often bilobed. Species many, all the tropics. All our species 
have been reduced to A. Cobbe Bl. by Hooker and King, but 
though very similar in the flower, the habits of the plants are so 
totally different that it is advisable to separate at least the most 
distinct forms. Radlkofer Sitzung der Math. Phys. Klasse Kgl.
