ACANTHACE.E. 



Thunbergia lauri folia, Lindl. Lankawi, Kwah (Curtis). 

 Perlis in hedges. Kanga. Bangtaphan (Keith). 



It is curious to see this plant, usually a lofty 

 jungle climber, growing low in hedges as at Kanga. 



Distrib. Arracan to Malacca. 



Th. fragrans, Eoxb. Perlis, Tebing Tinggi, quite glabrous- 

 Possibly an escape from cultivation. I have only seen 

 it elsewhere as a garden escape. 



var. javanica, Lankawi (Curtis), Perlis, Bukit 

 Lagi, and Tebing Tinggi, Setul. 



All these forms are only hairy beneath on the 

 nerves, very different from the plant on the limestone 

 rocks at Gua Batu, which is quite woolly on the back 

 of the leaves. The true fragrans is an Indian plant.
