CLASSIFICATION 151 



SECTION I. FRUMENTA 



1. T. vulgar e, 3. T. durum. 



2. T. turgidum. 4. T. polonicum. 



SECTION II. SPELTAE 



5. T. Spelta. | 6. T. amyleum. \ 7. T. monococcum. 



8. T. venulosum. An apparently immature specimen collected in Egypt 

 and sent to Scringe by Professor Desfontaines. Scringe considered 

 it allied to T. monococcum, but larger with anastomosing prominent 

 veins ; probably a form of Indo-Abyssinian T. dicoccum. 



In 1824 Metzger, in his Europaeische Cerealien, adopted the species 

 recognised by Seringe in his Monographic dcs cereales de la Suisse, only 

 leaving out the doubtful T. venulosum, and in 1827 Link (Hort. berol.) 

 adopted the same classification with the addition of T. compactum. 



Later, Seringe, in his Cereales europeennes (1841-42), classified the eight 

 species of wheats of his earlier monograph under the three genera 

 Triticum, Spelta, and Nivieria thus : 



Genus TRITICUM 



1. T. vulgare, Willd. (This included T. compactum, Host.) 



2. T. turgidum, L. | 3. T. durum, Def. | 4. T. polonicum, L. 



Genus SPELTA 



5. S. vulgar is. 6. S. amylta. 



Genus NIVIERIA 



7. \. monococcum. 8. .V. (?) venulosa. 



Vilmorin in 1850 (Catalogue mcthodique et synonymique des froments) 

 followed the classification of Seringe and Metzger, recognising seven 

 species, viz. : 



1. T. sutivum. 5. T. Spelta. 



2. T. turgidum. 6. T. amyleum. 



3. T. durum. 7. T. monococcum. 



4. T. {Htlonicum. 



Alefeld in 1866 (Landicirtschaftliche Flora) included all wheats under 

 the single species T. vulgare, except Polish wheat, which he placed in a 

 separate genus, Deina (D. polonicd). 



The species T. vulgare he divided into nine " varietal groups," viz. : 



1. T. vulgare durum. 6. T. vulgare arista turn. 



2. T. vulgare turgidum. 7. T. vulgare dicuccum. 



3. T. vulgare comporitum. 8. T. vulgare monococcum. 



4. T. vulgare compactum. 9 T. vulgare Spelta. 



5. 7. vulgare muticum.
