Outer glumes narrow. 

 Kernels white. 



Spike narrow, las, nodding ; typica. 



Spike wide, dense, erect. 



anomalum Kornicke (as var., 1895, p. 10; and 1908, p. 430). 



12. Hordeum intermedium atricornutum Kornicke (1908, p. 425). 



Outer glumes narrow. 



Spike narrow, lax, nodding typica. 



13. Hordeum intermedium nudihaxtoni Kornicke (1908, p. 429). 

 Outer glumes narrow. 



Kernels white. 

 Awns rough. 



Spike narrow, lax, nodding typica.

nuditransiens Kornicke (as var., 190S, p. 430). 

 Lemma of central floret awnless. 



nuditonsum Kornicke (as var., 1908, p. 426). 



14. Hordeum, intermedium nudimortoni var. novo. This variety was selected 

 from the progeny of a hybrid of haxtoni and nigrinudum. It is constant, and 

 with the other new forms described later is included here in order that the 

 list of principal varieties may be complete. It is a variety of intermedium 

 with black, naked kernels, lemmas of the central florets awned, outer glumes 

 narrow, and spike lax and nodding. 



15. Hordeum intermedium cornutum Schrader (1838, p. 471). 

 Outer glumes narrow. 



Kernels white. 



Spike narrow, lax, nodding typica. 



Spike wide, dense, erect. 



gymnanomalum Kornicke (as var., 1908, p. 430). 



16. Hordeum intermedium subaetMops Kornicke (1908, p. 425). 



Outer gHunes narrow. 



Spike narrow, lax, nodding typica. 



17. Hordeum distichon palmella var. novo. In the common 2-rowed barleys 

 there has apparently been no name used in recent years to include zeocriton, 

 erect um, and nut aim. Each of these has such a definite and specific use as a 

 subvarietal name that it can hardly be used to include the others. Jean des 

 Moulins in 1615, in the French edition of the work of Dalechamps (p. 333), 

 divided the barleys into two species, polystichon and distichon. The latter he 

 called pomole. Olivier de Serres, writing the same year (p. 99), used the 

 terms paumes and paumoules for the same barleys. The pomole of that date 

 was nearly identical with the group here designated palmella. Pomole, with 

 various spellings, as paumoule, pamelle, etc., is still applied popularly to the 

 common 2-rowed barleys in France. The name palmella is here used in 

 preference, as the Latin equivalent of palm, or little palm, doubtless referring 

 to the appearance of the spike. 



Outer glumes narrow. 

 Kernels white. 

 Awns rough. 



Spike narrow, lax, nodding. 



nutans Schuebler (as var., 1818, p. 36). 

 Spike wide, dense, the edges parallel ; awns not widely 



spreading erectum Schuebler (as var.. 1818, p. 36). 



Spikes wide, very dense, awns widely spreading. 



zeocriton Linnaeus (as sp., 1753. p. 85).
