=Cohesion of foliar organs.=--This takes place in several ways, and in
very various degrees; the simplest case is that characterised by the
cohesion of the margins of the same organ, as in the condition called
perfoliate in descriptive works, and which is due either to a cohesion
of the margins of the basal lobes of the leaf, or to the development of
the leaf in a sheathing or tubular manner. As an abnormal occurrence, I
have met with this perfoliation in a leaf of _Goodenia ovata_. The
condition in question is often loosely confounded with connation, or the
union of two leaves by their bases. In other cases the union takes place
between the margins of two or more leaves.

=Cohesion of margins of single organs.=--The leaves of Hazels may often
be found with their margins coherent at the base, so as to become
peltate, while in other cases, the disc of the leaf is so depressed that
a true pitcher is formed. This happens also in the Lime _Tilia_, in
which genus pitcher- or hood-like leaves (_folia cucullata_) may
frequently be met with. There are trees with leaves of this character in
the cemetery of a Cistercian Monastery at Sedlitz, on which it is said
that certain monks were once hung: hence the legend has arisen, that the
peculiar form of the leaf was given in order to perpetuate the memory of
the martyred monks. ('Bayer. Monogr. _Tiliae_,' Berlin, 1861.) It is also
stated that this condition is not perpetuated by grafting.

[Illustration: FIG. 8.--Pitcher-shaped leaf of _Pelargonium_.]

I have in my possession a leaf of _Antirrhinum majus_, and also a
specimen of _Pelargonium_, wherein the blade of the leaf is funnel-like,
and the petiole is cylindrical, not compressed, and grooved on the upper
surface, as is usually the case. A comparison of the leaves of
_Pelargonium peltatum_ with those of _P. cucullatum_ ('Cav. Diss.,'
tab., 106) will show how easy the passage is from a peltate to a tubular
leaf. In these cases the tubu
