200 THE WHEAT PLANT 



Ear bearded, narrow ; awns long ; glumes red, glabrous. 



T. dicoccum, var. rufum, Korn. Handb. d. Getr. i. 88 (1885). 



T. dicoccum rufum, Schvibl. Char, et descr. Cer. 29 (1818). 



T. amyleum, Ser., Krause. Getr. Heft V. 5, Taf. 2 A. B. (1837). 



T. amyleum, E., Metzger. Eur. Cer. 32 (1824), anc ^ Landw. Pfl. i. 114 (b) 

 (1841). 



T. vulgar e brunneum, Alef. Landw. Fl. 331 (1866). 



This variety has red glumes, but in other respects resembles the white- 

 glumed var.farrum, with which it is generally found mixed. 



I have met with two forms, viz. : (i) a small-eared, short-strawed Serbian 

 and Russian form with blunt-ended empty glumes (i, Fig. 133), and (2) the 

 Western European Red Emmer (2, Fig. 133), with taller straw, larger ears, later 

 habit, and empty glumes, with a claw-like apical tooth similar to that of White 

 Emmer (p. 197). 



Ear bearded, broad, and dense ; awns long ; glumes red, glabrous. 



T. dicoccum, var. pycnurum, Korn. Handb. d. Getr. i. 90 (1885). 



T. vulgar e pycnur a, Alef. Landw. Fl. 333 (1866). 



Two forms are recognised, viz. : 



FORM i. (T. amyleum, I., Metzger, Eur. Cer. 34) with pale red short ears 

 4-5 cm. long, 1-6 cm. broad, tapering towards both ends ; awns 16-18 cm. long ; 

 spikelets occasionally with three grains, which are less firmly enclosed in the 

 glumes than in most Emmers. 



Sent to Kornicke from Hohenheim as T. Cienfuegos and from some Botanic 

 Gardens as T. Hisbu. 



FORM 2 has dark red, longer ears 5-7 cm. long, 1-4 cm. broad, and widest at 

 the apex ; awns 12-16 cm. long (figured by Krause, Getr. Heft. V. 9, t. 4 

 A. B.). 



Ear bearded with doube spikelets ; awns long ; glumes red, glabrous. 



T. dicoccum, var. Schiibleri, Korn. Arch.f. Biontologie, ii. 410 (1908). 



Found by Kornicke in 1899 in the Botanic Garden at Poppelsdorf among 

 var. erythrurum ; he states that the grains are loosely held by the chaff, and pre- 

 sumes it is a hybrid with some form of T. vulgar e. 



Ear branched ; awns long ; glumes red, glabrous. 



T. dicoccum, var. erythrurum, Korn. Handb. d. Getr. i. 91 (1885). 



T. amyleum, F., Metzger. Eur. Cer. 33 (1824). 



T. vulgare phaeocladus, Alef. Landw. FL 332 (1866). 



Kornicke 's examples were derived from a cross. 



Ear with short awns ; glumes red, pubescent. 



T. dicoccum, var. Bauhini, Korn. Handb. d. Getr. i. 87 (1885). 

 T. amyleum, H., Metzger. Eur. Cer. 33 (1824). 

 T. vulgare Bauhini, Alef. Landw. Fl. 332 (1866).
