A STUDY IN ENDKMISM. 27# 



8. Munronia pumila, Wight. On the side of Ritigala. 

 Capsule with narrowly winged seeds, perhaps wind-carried, 

 though extremely improbably. Occurs in the dry zone, 

 though rarely. 



9. Walsura Gardneri, Thw. Summit. Fruit dull orange 

 and seeds with a white aril, bird-carried. Only recorded from 

 Hantane and Alagalla, both of them mountains near the 

 northern end of the moist zone, and from 2,000 to 3,000 

 feet. 



10. Olax zeylanica , L. Summit. Fruit drupaceous, scarlet, 

 half covered by the enlarged calyx, bird-carried. Common 

 in the moist low country. 



11. Salacia reticulata, Wight. Summit. Fruit a scarlet 

 berry, bird-carried: rather common in moist low country to 

 3,000 feet. 



12. Vitis pedata, Vahl. Summit. Fruit a berry, bird- 

 carried. Common in the dry zone. 



13. Desmodium Wightii, Grab.. Summit. No arrange- 

 ments for transport, so far as can be seen. Common in the 

 low country, and also occurs in South India, but as it occurs 

 about Badulla, is not altogether unlikely to occur in the dry 

 zone, and may progress by way of tank bunds. 



14. Dalbergia Ghampionii. Thw. Summit. Rather rare 

 in the moist region 2,000-4,000 feet. Pod very large and 

 compresssed, with one flat seed inside, about 2| by J inch, 

 flat and thin. It may have been carried by wind, but this is 

 extremely improbable, for in Ceylon the wind is as a rule very 

 gentle. The other countries recorded for this species are 

 South India and Penang to Borneo, so that it must be able 

 to travel in some way, but it remains doubtful how it reached 

 the summit of Ritigala. 



15. Weihea zeylanica, Baill. Summit. Fruit a fleshy 

 capsule, perhaps bird-carried. Common in the dry zone. 



16. Eugenia, spicata, Lam. The commonest tree at the 

 summit. Fruit fleshy, bird-carried. Very common in the 

 dry country.
