FUNGUS ON RUBBER. 



In the annual report of the Government Mycologist in Ceylon 

 (Mr, J. B. Carruthers) is the mention of a fungus which grows on 

 samples of Para rubber. It grows more abundantly on samples 

 treated with acetic acid, It is a species of Syncephalis and causes 

 red markings in the sample though not destroying its translucency. 

 Further investigations are being made. 



RUBBER VINES IN FRENCH INDO CHINA. 



In the Revue des Cultures Coloniales No. 98, (April, 1902) M. 

 GUSTAVE QuiNTARET gives accounts of two unidentified rubber 

 vines found in Annam and Laos respectively and a more extensive 

 account of these with the addition of seven more is published in 

 the Bulletin Economique of the Government of Indo-China, Series 

 2, No. 2, by M. ACHARD. Of these only three have been identified as 

 the botanical specimens of most were inadequate, not possessing 

 flowers. One called Mak Khao Ngua, is identified as Ecdysanthera 

 micrantha, Dec. an apocynaceous plant occurring in Laos and An- 

 nam and also a native of the Himalayas as far south as Ava. It 

 does not occur as far as is known in the Malay Peninsula. 



M. QuiNTARET has extracted a latex which appears very rich in 

 Caoutchouc and is readily coagulated by citric acid. The rubber 

 is of a blackish brown colour inclining to red and of excellent 

 quality and is already being exported. The fruits according to M. 

 ACHARD are eaten by the Laotians on account of their acid flavour. 

 The vines are tapped when they are 3-4 centimetres through ( 1 

 inch, to \\ inch.) There seems to have been no previous record of 

 Ecdysantliera } producing rubber. 



A second species Khua Mak Khao Nghe has been identified as 

 Paramcria barbata, of Pierre. It gives a black rubber. 



The Paramerias all give a more or less valuable jungle rubber, 

 but hardly of first quality. 



Khua Katang Katiou is a species of Micrcchitcs, and the name 

 Mictechites uapceusis, is proposed for it. The liane is slender, 

 attaining in some specimens a diameter of .08 metre (3 inches) 

 and a plant cut dow n by M. Ac HARD measured along its principal 

 stem 72 metres (222 feet). A M. FORET stated that he had seen 

 stems two years old as much as 20 metres in length. The rubber 

 is black.
