From Maison Carree, Algiers. Seeds presented by Prof. L. Ducellier, 

 L'Ecole d'Agriculture. Received February 26, 1921, Quoted notes from 

 Ducellier, Les Bles du Sahara, except as indicated. 

 "The Sahara wheats appear to be perfectly adapted to the Saharan regions; 

 the heads and seeds are normally developed. The numerous related forms 

 which are in the oases seem to indicate an ancient culture. The heads are re- 

 markably well filled, each measure of grain sown yields 10 to 100 measure, and 

 in certain cases, considering the climatic conditions, the yield is comparable 

 with the best wheats of Europe. It does not seem that the ordinary varieties 

 of wheat, even those with a great yield, can become under the best conditions 

 as floriferous as certain Saharan varieties. This peculiar property of the 

 Saharan wheats makes them interesting objects of hybridization."
