230 Ifiherltance of Tight and Loose Paleae in Oats 



straight. It is important to note this condensation of the occasional 

 large spikelet in the tight oat as compared with the extreme laxity of 

 the Avena nuda type. 



Ligowo. 



In all its essentials this variety resembles Thousand Dollar. It 

 also has white, tight, awned outer paleae and spreading panicles. The 

 grain, however, is somewhat plumper and there seems a greater tendency 

 towards 3-grained spikelets, though no 4-grained have been noticed, 

 possibly because no large field crop has been available for inspection as 

 in the case of Thousand Dollar.

Nuhischer Schwarzer 



is a shorter strawed oat than the two just described. It also differs 



in being a black tartarian. Save for the size and shape of the grain all 



other points are similar, 



Avena nuda. 



Two distinct features characterise the spreading panicles of this 

 species: — 



{a) The long, dangling spikelets in which there may be as many as 

 nine flowers (cf. Fig. 1), and 



(h) The readiness with which the grain drops out from between 

 the paleae when mature.
