Plant Introduction Unit 
A total of 1,425 new plants were introduced into Singapore via exchanges, 
purchases, gifts and collections in neighbouring countries. Of these, 1,023 were 
obtained through exchanges carried out with botanical and horticultural institu- 
tions, nurseries and private collectors all over the world. 
A number of plants introduced in previous years have been utilised for 
roadside planting in Singapore. Some of them have adapted exceedingly well to 
the local environment. Among these are the Rain Tree ( Enterolobium samari). 
Flame of the Forest ( Delonix regia), Mexican Lilac ( Gliricidia sepium) and the 
Cherry Tree ( Muntingia calabura). Among the ornamental plants introduced, the 
following have been especially successful in parks and home gardens: —

Yellow Bells ( Stenolobium stans) 
Peacock Flower ( Caesalpinia pulcherrima) 
The hybrid Mussaendas 
The Jade Vine ( Strongylodon macrobotrys) and
