Atavism by Seeds and Buds. Ill 
leaves project to right and left, and their side branches 
are horizontal, making the whole shoot flat with definite 
dorsal and ventral surfaces. The bush which grows in 
our garden and bears several branches with similar bud- 
variations, I owe to the kindness of MESSRS. ZOCHER & 
Co., nurserymen in Haarlem. The variety can only be 
propagated by cuttings, as it never flowers, 1 and these 
produce reversions of this kind pretty regularly, both in 
the nursery of Messrs. ZOCHER & Co. and elsewhere. It 
appears to have been first observed in 1863 by CARRIERS 
in Paris, 2 and since that time by many others. This re- 
markable case is well worthy of a closer study. The 
perfectly analogous Ta.rus baccata fastigiata never ex- 
hibits atavism by bud-variations, so far as I know. 3 
The phenomena of bud-variation have hitherto not 
received from botanists the attention they deserve. In 
a few cases we know that the phenomenon is preceded by 
a s-ectorial segregation, as for instance in striped flowers 
(13) and variegated leaves ( 24) ; but as a rule there 
is no available information even on this point. Another 
point which awaits investigation is the nature of the 
offspring of self -pollinated bud-variants. 4 It seems cer- 
tain that new types sometimes arise in this way, but much 
of the proof in favor of this will not bear scrutiny. Under 
these circumstances it seems desirable to direct more gen- 
eral attention to this phenomenon 5 by means of some
