19193 to 19195— Continued. 



relatively early; very robust; little subject to attacks of fungous dis- 

 eases; very much valued by the natives for food. This variety requires 

 very little cultivation. It must be sown a month and a half or two 

 months before the end of the rainy season. The submerged fields are 

 very prolific for this kind of rice." (Liszewski.) 



19194. 



" Talifori. Mountain rice. Plants strong, of medium height ; early. 

 Period of growth from three to four months, which allows the natives 

 to harvest two crops of this rice in one season. Sown in May or June, 

 a month and a half before the end of the rainy season ; last sowing in 

 August and September. It is a good yielder. The rice is valued by the 

 natives for food and is considered the most nutritious of the mountain 

 rices. According to tradition this rice is the most ancient of all the 

 rices of Africa and is very characteristic of the region west of French 

 West Africa." {Liszewski.) 



19195. 



" Kontondi. Valley rice. Plants tall, vigorous, slightly rough ; straw 

 slightly hollowed; requires a dry seed bed; absorbs much of the nitrog- 

 enous matter of the soil ; is a prolific bearer and must not be sown two 

 years in succession in the same place. As a food this variety of rice 

 is not valued by the natives, so that it would be difficult to procure, since 

 it grows very far from the routes of travel." (Liszeivski.)
