REFERENCES TO HOPI COTTON AND SPECIMENS IN HERBARIA 

 The specimens of Hopi cotton in the U. S. National Herbarium, the 

 Economic Herbarium of the U. S. Department of Agriculture, and 

 those supplied Sir George Watt by Mr. L. H. Dewey, of Washington, 

 D. C, and Mr. W. Lawrence Balls, of Cairo, Egypt, are all descended 

 from the original seed given Dr. Hough by Sam Pawiki. 1 Professor 

 Balls in his experiments on Mendelian inheritance in cotton used 

 seed of Hopi cotton supplied by the U. S. Department of Agriculture, 

 which was grown in Waco, Texas, from the original Arizona seed. 2 

 This accounts for the close similarity of the Egyptian and Washington 

 specimens which evidently puzzled Dr. Watt and shows the fallacy 

 of his theory of the origin of the " Hindi weed " cotton of Egypt as 

 "but an older acclimatized (and possibly recessive) hybrid of 

 Moqni." :; 



1 The original seed was received under the name " Moqui " and the speci- 

 mens grown therefrom, which are now in several herbaria and mentioned in 

 the two works referred to below, were so labelled. See footnote 2 on page 6.
