THE SPECIES AND VARIETIES OF CULTIVATED 
WHEATS. 
The wheats of the world fall into three well-defined species :— 
1. Triticum sativum, Lam. ( = Triticum vulgare Vill. in erwei- 
tertem Sinne of Koernicke).' 
2. Triticum polonicum, L. Polish wheat. 
3. Triticum monococcum, L. Einkorn. 
The wheats of the whole of the Continent of India, so far as we 
have been able to ascertain, belong to the first of these three 
species. These species are well marked and may be distinguished 
as follows :— 
CONSPECTUS OF THE SPECIES. 
I. The tooth (Seitenzahn) of the outer glumes blunt, round- 
ed or absent. Pale undivided. Apical spikelet fertile. 
1. T. sativum, Lam. Outer glumes shorter than the flower- 
ing glumes, parchment-like. Pale the same length 
as the flowering glume. 
2. T. polonicum, L. Polish wheat. Outer glumes as long or 
longer than the flowering glumes, papery. 
II. The tooth (Seitenzahn) of the outer glumes acute or acu- 
minate, stiff, the ripe pale divided into two halves. 
3. T. monococcum, L. Einkorn or one-grained wheat. 
The first of these three species, Trztecwm sativum, Lam., is sub- 
divided into six sub-species as follows :—
