Tlic Inheritance of Fasciations. 495 
These phenomena have been more closely investigated 
by NESTLER who regularly found inside the terminal bud 
of a fasciated branch a line of fasciation instead of a 
point, in other words a growing comb instead of a grow- 
ing cone. 1 The leaves arising from this latter are pro- 
duced in very large numbers and in an abnormal arrange- 
ment, and in consequence of this, the disposition of the 
leaves on fasciated stems tends to be extremely irresfular ;

but although this subject is obviously very important in 
its bearing on the whole question of phyllotaxy, it still 
awaits a thorough investigation. In this respect it would 
be particularly valuable to make a study of fasciations in 
conifers, for our knowledge of the normal structure of 
their cone of vegetation is much more extensive than it 
is in regard to that of angiosperms. 2 Moreover there 
is no lack of material, for Cryptomeria japonica mon- 
strosa and the fasciated varieties of several other species 
are on the market (Fig. 109). 
Besides the cases of ordinary fasciation, and of those 
in which the surface may be bent by unequal secondary 
growth, there are some cases of most peculiar conforma- 
tion which hitherto have been very little investigated. It 
is not known whether these are the expressions of the 
same internal character or whether they must be referred 
to special factors. Their morphological structure is in 
favor of the latter view ; but the former is supported by 
the fact that they have hitherto always been observed in 
conjunction with ordinary fasciations, i. e., in species 
which are particularly liable to them. Examples are af- 
forded by the multi-radiate and annulate fasciations.
