35314. Triticum durum Desf. Durum wheat. 

 '•(No. 1809a. Iss>-l-kul, western Siberia. Januar\' 27, 1913.) Var. melanopus 



Komicke. A few ears of a valuable black-bearded summer durum wheat 

 ha%-ing the bracts close together. Selected by Mr. I. M. Karsin. at Issyl-kul, 

 who finds that, in dry western Siberia, wheat with short dense ears requires 

 less moisture to mature and is less easily injured by long drought than wheat 

 with long, loose, open ears. This variety, melanopus. especially needs but 

 little moisture to ripen fully. "

'"The field characteristics of the Meho and Ishan varieties of cotton are very 

 much alike, the only obvious differences being in the seed. The Meko has a 

 fuzzy seed while the Ishan is clean seeded, with the exception of a small tuft 

 at the beak. Although treated as annuals, both varieties are perennial and 

 mature into tall shrubs about 15 feet high, ha\'ing numerous suberect and some- 

 times rather drooping branches; the intemodes are long, which character com- 

 bined with the taU habit gives them a straggly appearance. Both varieties 

 appear liable to the same diseases. Two diseases common in this district are 

 confined to them and so far have not attacked the American varieties under 

 trial. One of these diseases is a peculiar leaf-curl which affects the whole plant; 

 the other disease is also of a ver}- marked character and attacks the veins of the 

 leaves, turning them black with formations of a yellow, waxy material. Both 

 diseases are under investigation. " (Evans.) 



"Local varieties, and have probably been grown in west Africa for 200 to 300 

 ^ years. They resemble the Peru\-ian t\-pes in seed and lint. There is a recent

 gives a chapter on the cotton of the region. " (F. L. Leuton.)
