Verbenaceis. 345 



\Peristrophe tzfictoria, Nees, is given for Ceylon by Anderson in Thw. 

 Enum. 234 on the faith of a specimen from Walker in Herb. Kew. It 

 was probably cultivated here. This locality is not given in Fl. B. Ind., 

 but another species, P. inonta7ia^ Nees, is entered there (iv. 556) 

 ' Ceylon frequent,' I know not on what authority. This latter is a hand- 

 some plant of S. India, figured in Wight, Ic. t. 1553, and may also have 

 been cultivated here.]

We have 26 species, nearly all low-country plants, and especially 

 found in the dry region, to which 11 are entirely confined, whilst only 2 

 are restricted to the moist country; 7 species extend into the lower 

 montane zone. Glossocarya and 3 species of Premna seem to be 

 endemic.
