348 REPORT OF THE CONFERENCE ON GENETICS. 
B22 was a soft, white, bearded wheat, hairy and spreading, with 
white grain ; it did not vary and was killed by frost in 1891. 
B23 was a soft, white, bearded wheat, glabrous, with a slender ear like 
a spelt, and white grain. It produced a marked variation in 1888 : 
B°31 was like B83, did not vary again, and was destroyed in 1890. 
B’32 was a soft rosy-white, beardless wheat, of the Odessa type, 
with red grain. It varied in 1889, and produced : 
B°321, which was like B32, and destroyed in 1890. 
B°322 was a soft wheat, with long, beardless, white ear, 
which shed its seed badly. Destroyed in 1890. 
B’323 was a soft wheat, rosy, bearded, with a square ear 
and white grain. Destroyed in 1890. 
B°33 was a soft wheat, pale red, beardless, with pale red grain; it 
varied in 1889, and produced : 
B’331, which was the same as B’83 and destroyed in 
1890. 
B?332 was a soft wheat, with a square pyramidal, red, 
beardless ear, red grain, of the Noé type. Destroyed 
in 1890. 
B’333 was a beardless, soft, white wheat, with slender, 
curved ear, and long white grain. Destroyed in 1890. 
B’*334 was a bearded, rosy, soft wheat, with long yellow 
grain. Destroyed in 1890. 
B25 was a bearded, soft, white wheat, very much the same as the B’4, 
but later; grain pale red. This was a stunted plant, and was destroyed in 
1888. 
B°’6 was a rosy-coloured, soft wheat, bearded, ear square, compact at 
the tip, grain very wrinkled, poor, and was destroyed in 1888.

C'!.—This wheat, very curious in itself on account of its ambiguous 
characters, has produced, since 1887, several variations which we shall now 
examine ; but the type has always persisted. One can say, however, that at 
the present time, after eighteen generations, itis nearer to Tr. durum than 
it was in 1887, when my father described it for the first time. It did not 
vary until 1894; but in that year, seven plants cut of ten were beardless. 
Only one of the bearded plants was preserved, which reproduced itself 
well in 1895, but in 1896 gave two forms, C'l and C'2. 
C'l was like C!; in 1897 it varied again and gave 0'11 and C112. 
C'11 was like C' and ©'l, and did not vary for four years ; 
but, in 1901, it produced C'111, €'112, and C'113. 
C'1ll, for the most part, was very like the type, and 
has never varied again to the present time. 
C1112 was very like C'12 (see below), but was larger: it 
was a grey hairy turgidwm, with yellow grain. It 
produced, in 1902, some plants with rosy-coloured ears,
