PLATE LXII 



Ends of main stalks of two plants of Dale Eg>'ptran cotton, showing simple fruiting 

 branches and closely similar axillary fruiting branches. In one case the terminal bud 

 was aborted, while in the other it was transformed into a boll subtended by an abnor- 

 mal bract-like leaf with the stipules enlarged and the blade entire, instead of 5-lobed. 

 Plants grown at Bard, Cal. Photographed by Mr. C. B. Doyle.
