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. 
Gust.WE 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 ii inch.) There seems to have been no previous record of 
Ecdysanthera , producing rubber. 
A second species Khua Mak Khao Nghe has been identified as 
Parameria barbata, of Pierre. It gives a black rubber. 
The Paramerias all give a more or less valuable jungle rubber, 
but hardlv of first quality. 
Khua Katang Katiou is a species of Micrechites, and the name 
Micrechites napeensis , is proposed for it. 1 he liane is slender, 
attaining in some specimens a diameter of .08 metre (3 inches) 
and a pfant cut down by M. ACUARD 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.
