IV. NEW AND RARE PLANTS 

 FROM THE MALAY PENINSULA. 



By H. N. Ridley, C.M.G,, F.R.S. 



This paper includes a number of new species recently- 

 received in various collections chiefly made by members of 

 the Museums Department in the Federated Malay States 

 and others from a collection made by myself in Kelantan 

 in 1917 ; together with various emendations of species of 

 earlier collections which in the course of my work on the 

 Flora of the Malay Peninsula I have found it necessary 

 to make. 



A small but valuable collection was made on the East 

 Coast by Mr. I. H. N. Evans, Asst. Curator, Perak Museum, 

 of which several new species are described, besides which 

 he added to our flora Securidaca tavoyana, and Celastrus 

 paniculata from Pahang. The latter is a verv widely dis- 

 tributed plant, occurring in India and throughout the Malay 

 archipelago, but curiously has been till now missing from 

 the Malay Peninsula. 



A small collection made by a native employe of the 

 F.M.S. Museums Department on Gunong Binlang on the 

 Kedah-Perak boundary contained a number of valuable 

 additions including a remarkable new Genus of 

 Rhanmaceae, viz. : — Oreorhamnus. 



On the invitation of Mr. and Mrs. Graeme-Anderson 

 I visited Kelantan in February 1917, and enjoyed their 

 hospitality for some weeks at Chaning Estate on the 

 Kelantan river above Kuala Lebir, and on my way back 

 stopped with Mr. R. J. Farrer at Kota Bharu. The flora of 

 Kelantan was very little known. I formerly received a 

 number of specimens and live plants from Dr. Gimlette 

 at Kuala Lebir, and had landed once in 1889 on the sea 

 coast near the mouth of the Kelantan river for a few hours. 

 Near the Chaning Rubber Estate were patches of forest 

 untouched by man and here I found the flora typically 

 Malayan, but vdth a good many new species. Here in a 

 sandy spot in a forest I found a patch of Trichopus Zey-^ 

 lanicus which I had met with many years ago at one spot 

 in the Tahan woods in Pahang ; otherwise it is only known 

 from Ceylon. 



A day or two at Kuala Lebir gave me a curious 

 Rubiaceous shrub obviously of the same genus as a dwarf 

 shrubby plant collected by me at Klang gates and which 

 I had referred to Xanthophytum Bl. Further examination 

 showed that it did not belong to Blume's genus and I have 

 made a new genus Aleisanthia for the two species : it is 

 allied to the genus Grania. Curiously I found a true 

 Xanthophytum on the banks of the Pehi river opposite 

 Chaning Estate, another generic addition to our flora. The 

 country round Kota Bharu is mostly covered with rice 

 fields and other cultivations. I noticed here plots of Coleus 

 tuberosus, a plant seldom cultivates further south. I
