Plot, in his 'History of Oxfordshire,' considers fasciation to arise
from the ascent of too much nourishment for one stalk and not enough for
two, "which accident of plants," says Plot, the German virtuosi ('Misc.
Curios. Med. Physic. Acad. Nat. Cur.,' Ann. i, Observ. 102,) "think only
to happen after hard and late winters, by reason whereof, indeed, the
sap, being restrained somewhat longer than ordinary, upon sudden thaws
may probably be sent up more forcibly, and so produce these fasciated
stalks, whereas the natural and graduated ascent would have produced
them but single." Prof. Hincks' explanation is, however, more near to
the truth, and his opinion is borne out by the frequency with which this
change is met with in certain plants which are frequently forced on
during their growth, as lettuce, asparagus, endive, &c., all of which
are very subject to this change. In the 'Transactions of the
Horticultural Society of London,' vol. iv, p. 321, Mr. Knight gives an
account of the cultivation of the cockscomb, so as to ensure the
production of the very large flower-stalks for which this plant is
admired. The principal points in the culture were the application of a
large quantity of stimulating manure and the maintenance of a high
temperature. One of them so grown measured eighteen inches in width.

The list which is appended is intended to show those plants in which
fasciation has been most frequently observed. It makes no pretension to
be complete, but is sufficiently so for the purpose indicated: the *
denotes the especial frequency of the change in question; the !
indicates that the writer has himself seen the plant, so marked,
affected in this way. The remainder have been copied from various
sources.
