globe Europe, Africa, Asia, America, and New Holland. Fagonia and Tribulus are both 
found in the south of Europe as well as in India, The former abounds in the Ceded Districts 
and also in Mysore, but [ have never seen it in the Carnatic, the jatter, Tribulus, is one of the

anthelmintic. 
Remarks on Genera AND Species. In so faras Indian Bota

accompanying figure will show how erroneous that is, and [ doubt not the same will be found 
in several of the others and prove that they all form but one Species,
