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.
We now come to a small section of plants which climb by means of the
produced midribs or tips of their leaves.
LILIACEAE.--Gloriosa Plantii.--The stem of a half-grown plant
continually moved, generally describing an irregular spire, but
sometimes oval figures with the longer axes directed in different
lines.
