RIVET OR CONE WHEAT 



247 



The long growing period, number of culm leaves, velvety leaf-surface, 

 the height, surface, and pithy interior of its straw, the density of the ear, 

 as well as the frequent occurrence of compound ears, indicate a close 

 relationship of T. turgidum with the tall European forms of T. dicoccum. 



A few forms suggest affinity with T. durum, while others appear to be 

 allied to T. vulgare ; these are probably hybrids.
