 results obtained in the efforts made to establish a trade in oranges be-

EtherinöTON, I., TheArnatto Dye Plant. Blxa Orellana. 

 (Tropical Agriculturist. Vol. XXV. p. 230— 231. July 1905.) 



A general description of the plant, and the collection and pre- 

 paration of arnatto seed is given, and it is suggested that it might be 

 cultivated with profit in Ceylon as a minor product. 



Two varieties of arnatto occur in Ceylon, one with rose coloured 

 flowers, red fruit and scarlet seeds, the other with white blossom, green 

 fruit and orange coloured seeds. The former gives a stronger dye, which 

 is more valuable, but it can only be made into paste as it is worthless 

 when dried hard. The green fruited arnatto yields yellow dye^ which can 

 be made into paste or dried hard. 



The plant ranges in Ceylon up to 3000 ft, it is easily raised from 

 seed, and under favourable conditions begins to yield in two years.
