Deina polonica velutinum, Alef. Landw. Fl. 336 (1866). 



This and its glabrous counterpart var. levissimum are two of the most widely 

 known varieties of T. polonicum. 



Young shoots, erect or semi-erect. 



Straw, tall, 125-130 cm. (about 50-52 inches) high ; upper internode almost 

 solid. 



Ear, lax, 15-17 cm. long, 10 mm. across the face, 12-15 mm. across the 2- 

 rowed side ; spikelets 15-22, 30-35 mm. long, 3-4 abortive at the base of the 

 ear, the rest 3- to 4-flowered, the lower 2 or 3 flowers of each fertile ; D = 15-18. 



Edges of the rachis fringed with hairs 1-2 mm. long. 



Empty glume, thin, narrow, lanceolate, those of the lower flowers 30-35 mm. 

 long, keeled, outer half with five prominent longitudinal ciliate nerves, the 

 hairs very fine ; apex with short acute primary tooth and rudimentary secondary 

 tooth close to the primary tooth (i, Fig. 147). 



Flowering glumes of the two lower flowers with awns 9-11 cm. long, those of 

 the upper flowers with a short point about i mm. long, palea of the lower flowers 

 about half the length of the flowering glume. 



Grain, flinty, long and narrow, pointed at the base, blunt at the apex ; 10-12 

 mm. long, 3-3-1 mm. broad, 2-9 mm. thick (i, Fig. 148). 



Glumes white, pubescent ; ear dense ; awns long ; grain white. 



T. polonicum, var. Martinari, Korn. Handb. d. Getr. i. 104 (1885). 



Kornicke's type has dense ears, 8 cm. long, attenuated towards the apex 

 the empty glumes with awn-like points 6 mm. long. It originated from a 

 sample exhibited as " Grano S. Martinaro " at the Italian Exhibition in Paris, 

 1878. 



Trigo Chile de fideos (i, Fig. 150). A form of var. Martinari received from 

 Argentina and Spain. 



Young shoots, semi-erect. 



Straw, slender, of medium height, 110-115 mm. (42-44 inches) high ; upper 

 node solid. 



Ear, dense, 8-9 cm. long, outline more or less ovate, tapering towards the 

 apex ; compressed, 10-15 mm. across the face, about 20 mm. across the 2-rowed
