others of our higher mountains appear to be species of the 

 lower country which, having found their way to the tops of the 

 mountains and being able to maintain themselves there, have 

 become modified into alpine forms or adapted in one way 

 or another for life under mountain conditions. 



These plants with Malayan affinities are: — 

 Polyalthia pulchva, King Wehera. 



Calophylluni veniistuni, King Lasianthus. 



Garcinia monantha, Ridl. Cephaelis. 



A dinandra. Pentaphragmn. 



Elceocarpns. Einbelia myrtillus. 



Evodia. Ardisia. 



GoDiphandra. Symplocos. 



Salacia perakensis, King. Alyxia. 



Euonymiis jav aniens, Bl. Gaertnera. 



Parinarium. Gesneracece. 



Pygeuni. Nepenthes. 



' Polyosma. Balanophora. 



Carallia. Loranthiis. 



Melastonia. Henslowia. 



A nerincleistus. CinnainoviMn mollissimuin. 



Oxyspora. Choriophyllinu. 



Sonerila. Orchidece (all). 



Phyllagathis. Dischidia. 



Medinilla. Camptandra. 



Begonia. Geostachys. 



Heptaplenrum. Cnrcnligo, 



A rgosteimna. Sciaphiln. 



Urophyllum. Aracece. 



Timonius. Gnetum. 



In the case of the genera of world-wide distribution, those 

 included in this list, e.g. Begonia and Ardisia, are represented 

 by species either occurring in or allied most closely to the 

 species in the forests of the lower zone. 



A number of these species have obviously crept up the 

 Teku rivers or Tahan rivers, occurring in the adjacent lo\Ner 

 country, such as the Gesneraceae, Araceae, and Melastomaceae ; 

 some, like the Loranthi and Ardisia, have drupaceous fruits 

 constantly dispersed by birds and easily borne to these heights. 



It is interesting to note that practically all the plants with 

 seeds easily borne by wind, like Dischidia, Orchidece, Sciaphila, 

 and the vascular Cryptogams, are Malayan forms, with the one 

 exception of Lycopodiwn Carolinianum. 



Comparatively few of our highest mountains here have 

 been thoroughly explored as yet — perhaps the best known are 

 Mt. Ophir and Kedah Peak. The former, small as it is, bears 

 a number of plants which are almost or quite peculiar to this 

 mountain and Gunong Tahan. A list of those common to 

 both will be of interest : — 



Illicium camhodianuni, Hance. Spathoglottis aurea, Lindl. 

 Anneslcea crassipes, Hook. fil. Arundina speciosa, Bl.
