WILD EMMER 183 



is observed even when the germinating capacity is tested on grains free 

 from the glumes. 



In the large-grained forms both grains germinate at the same time 

 when freed from the glumes. 



VARIETIES OF T. dicoccoides, Korn. 



1. Glumes white, glabrous .... var. Kotschyanum, mihi. 



2. Glumes white, pubescent .... var. fulvovillosum, mihi. 



3. Glumes reddish, glabrous . ... var. Aaronsohni, mihi. 



4. Glumes black or striped, glabrous . . var. spontaneonigrum, mihi. 



5. Glumes black or striped, pubescent . . var. spontaneovillosum, mihi. 



Glumes white, glabrous. 



T. dicoccoides, var. Kotschyanum, mihi (Figs. 122, 123). 



This is one of the commonest varieties on Mount Hermon. It possesses 

 glabrous yellowish-white glumes, a conspicuous frontal tuft, and long hairs on the 

 edges of the rachis. The ears are 6-8 cm. long and have 12-15 spikelets. 



T. dicoccoides forma Straussiana, Schulz (Ber. d. Deutsch. Bot. Ges. xxx. 

 226 (1913), is the western Persian representative of this variety ; forma 

 Kotschyana, Schulz (!), has a less hairy rachis and is probably a cross or a form 

 produced by cultivation. 



Glumes white, pubescent. 



T. dicoccoides, var. fulvovillosum, mihi (Figs. 122, 123). 



A common variety received from Mount Hermon. It is similar to var. 

 Kotschyanum, but with soft white hairs on the glumes and long yellowish or 

 orange-brown hairs on the rachis. The apical tooth of the empty glume is 

 generally short and blunt. 



I received from Dr. M. Kornicke a very late form which must be classed 

 with this variety (4, Fig. 123). It has large coarse spikelets 1-5-1-8 cm. long, 

 the outer glumes clothed with long silvery hairs and terminated by a curved 

 tooth 4-5 mm. long (9, Fig. 119); the awns are exceptionally stout and 18-20 cm. 

 long. Figured also by Aaronsohn (Bur. PI. Ind. Bull., No. 180, PI. vii. Fig. i). 

 It is probably a hybrid of T. dicoccoides and T. durum. 



Glumes reddish, glabrous. 



T. dicoccoides, var. Aaronsohni, mihi (4, Fig. 122). 



T. dicoccum, var. Aaronsohni, Flaksb. Bull. App. Bot., Petrograd, vii. 767 

 (1914). 



This variety resembles var. Kotschyanum, but its glumes are pale brownish 

 or pinkish-red. 



A common large-seeded form of it from El Hadr very closely resembles the 

 cultivated Emmers (T. dicoccum) of Abyssinia and India in its erect straw, pale 

 yellowish-green leaves, comparatively glabrous rachis, and early ripening period.
