which there can be practically no doubt that they have been 
introduced in this way. These are : — 
Scævola Koenigii 
A total of 43 species, representing 39 genera and 24 fami- 
lies, of which 39 species, 37 genera, and 24 families are 
Maldivian. 
Of these 43 species, only 36 occur in Ceylon, and only 30 
and 29 on the Malabar and Coromandel coasts of Southern 
India respectively (or 39 in Ceylon and Southern India 
together), so that it is evident that the sea-borne flora of the 
islands at any rate is derived in part from other countries 
than those nearest to them. We may best consider the 
origin of this flora by dealing flrst with the effects likely to 
follow from the directions of the currents and winds 
at different seasons. Reference to any atlas of physical 
geography will show these ; a good current map forms 
Plate I. in Schimper’s work, and the map at the end of this 
paper gives the currents for the western half of the Indian 
Ocean.
