The samples of Rhode Island bent seed examined may be con- 

 sidered fairly representative of New England grown seed which has 

 not been recleaned. Several kinds of incidental seeds which are 

 characteristically American were found in these samples. Further- 

 more, the weed seeds characteristic of South German mixed bent 

 seed were absent from these samples. They contained no seed of

Fig. 11. — Seeds characteristic of South German mixed bent seed (enlarged and natural size): 1, Silky 

 bent grass {Apcra spica-venti); 2, tufted hair-grass (Dcschampsia caespitosa); 3, wavy hair-frass {Dcs- 

 champsia flexuosa); 4, wood meadow grass {Poa nemoralis); 5, Weingartneria canescens; 6, wood meadow 

 rush {Juncoides nemorosum); 7, spurry (Spergula arvensis); 8, poppy {Papaver spp.); 9, starwort (Alsine 

 graminea); 10, St. John's-wort {Ilypcricum perforatum); 11, willow herb (Epilobium sp.); 12, heal-rJl 

 (Prunella vulgaris); 13, plantain (Planfago major); 14, scentless camomile (Matricaria inodora); 15, Qie- 

 weed (CrepisvireTis); 16, nipplewort (iapsama communis). 



velvet bent (Agrostis canina), which has been found in every lot of 

 South German seed examined. 



The samples of colonial bent seed were too few to afford specific 

 conclusions as to the range of the characteristic incidental seeds 

 occurring with this seed; but certain kinds found are different from 

 those occurring with seed of redtop or fine bents from other sources.
