do not move over a wide space, as could be seen when a shoot was
securely tied to a stick. The leaf in this case followed an
irregular course, like that made by the internodes.

Adlumia cirrhosa.--I raised some plants late in the summer; they
formed very fine leaves, but threw up no central stem. The first-
formed leaves were not sensitive; some of the later ones were so, but
only towards their extremities, which were thus enabled to clasp
sticks. This could be of no service to the plant, as these leaves
rose from the ground; but it showed what the future character of the
plant would have been, had it grown tall enough to climb. The tip of
one of these basal leaves, whilst young, described in 1 hr. 36 m. a
narrow ellipse, open at one end, and exactly three inches in length;
a second ellipse was broader, more irregular, and shorter, viz., only
2.5 inches in length, and was completed in 2 hrs. 2 m. From the
analogy of Fumaria and Corydalis, I have no doubt that the internodes
of Adlumia have the power of revolving.

Corydalis claviculata.--This plant is interesting from being in a
condition so exactly intermediate between a leaf-climber and a
tendril-bearer, that it might have been described under either head;
but, for reasons hereafter assigned, it has been classed amongst
tendril-bearers.

Besides the plants already described, Bignonia unguis and its close
allies, though aided by tendrils, have clasping petioles. According
to Mohl (p. 40), Cocculus Japonicus (one of the Menispermaceae) and a
fern, the Ophioglossum Japonicum (p. 39), climb by their leaf-stalks.
