A Catalogue ot the Chief Introduced and 

 Naturalized Species found in Ceylon. 



To complete the i)receding catalogue, we have made the 

 following, in which we have included all the species we know 

 to be regulurly cultivated in the Colony, or to have escaped 

 and estabhshed themselves as weeds therein. Its length will 

 surprise many people, as also the fact that it includes nearly 

 all of our useful plants. 



It is very difficult tu make a hst like th=s accurate or complete. 

 New weeds may any day make their appearance, or old ones 

 may disappear, and new cultivations may begin. We have 

 excluded the purely decorative garden plants, unless, as in 

 the case of Cosmos, they have spread into the country and 

 established themselves, or are used in hedges 01 in similar ways.
