The Inconstancy of Fasciated Races. 
In races of this kind all conditions of the environ- 
ment are of importance. By crowding, the proportion 
of fasciated individuals can be reduced, for instance, from 
Fig. in. Agrostemma Githago. 
A plant the main axis of which 
had been cut off at o. The cotyl- 
edons have dropped off at C and 
C'. Their axial twigs are fasciated, 
and instead of producing decussate 
leaves, bear multiple whorls. They 
split occasionally at the nodes, 
forming forks with branches at 
a, b, c, d } e and f. Just above f the 
calyx of the flower is spiral (kk), 
and fused with the uppermost fo- 
liage leaf (fr), by which the flower 
stalk is seen to be twisted. (1892.) 
40 to 5%. Even if the number of fasciations is calcu- 
lated per area of the bed, a small number of specimens 
give a prospect of obtaining more fasciations than a
