The Inheritance of Fasciations. 501 
larger number planted on the same area, but too close to- 
gether. The number of fasciations can be diminished 
by cultivation on sterile sand and increased by the addi- 
tion of manure. The most numerous and the finest in- 
stances of the anomaly are produced by cultivation in 
pots with heavy manuring and by subsequent transplan- 
tation to the beds; and so forth. 1 
Further, a considerable effect can be exerted on the 
production of fasciations, as upon that of monstrosities 
in general, by pruning and by the selection of buds which 
accompanies this process. Thus, GOEBEL says in his Or- 
gaiwgraphie 2 that fasciations can be artificially produced 
by diverting the "sap" with great intensity into a lateral 
bud which would otherwise have obtained only a small 
quantity of it. It is for this reason that fasciations are 
particularly abundant on adventitious branches and shoots 
from cut stems. Even in annual plants such as Phaseolus 
multiflorus and Vicia Faba, fasciation can be induced by 
cutting off the plant above the cotyledons. A plant which 
is peculiarly suitable for the demonstration of this method 
is Agrostemuia Git ha go, which in my cultures always 
produced an abundance of anomalies, but did so with 
greater certainty when I had removed the main stem, 
just above the cotyledons or the first pair of leaves. The 
axillary buds, which, as a rule, do not develop, grew out 
under this treatment and frequently became fasciated 
(Fig. 111). 
The phenomena of periodicity are also associated with 
the effects of nutrition. Lateral branches of fasciated 
shoots are usually of normal structure ; but broadened 
ones not infrequently occur amongst them. If they do,
