GROUP I. INDO- ABYSSINIAN EMMERS 



SECTION A. Speltae. Rachis fragile. 



Ear bearded ; glumes white, glabrous ; grain red. 



T. dicoccum, var. Ajar, mihi. 



T. Arras, Hochst. Flora, 31, 450 (1848). 



i. Abyssinian Emmer (2, Fig. 129). This variety I obtained under the 

 native Amharic name " Ajar " or " Agga," from Abyssinia, where it is grown 

 at an elevation of 5000-8000 feet. It is sown in June and harvested in 

 October, giving a six- to eight-fold return ; where irrigated it is sown in 

 November and December and reaped in May. 



It is closely related to the wild T. dicoccoides and, like it, is exceptionally early, 

 coming into ear at Reading about May 20-25 when sown in autumn (October- 

 December). 



Coleoptiles, 4- to 6-nerved, sometimes pinkish.
