Flaksberger records its occurrence in Siberia, Semiretchensk, Turkestan, and

 Young shoots, semi-erect. 



Straw, tall, 132 cm. (52 inches) high, stout, hollow. 



Ear, short and very dense, 4-5 cm. long, 12 mm. across the face, 18 mm.

2. A glaucous form cultivated in Madeira under the names Mocho de
