Excerpt from Beihefte zum Botanischen Centralblatt, Vol. 31: Original-Arbeiten, Erste Abteilung, Anatomie, Histologie, Morphologie und Physiologie der PflanzenThese nodal scales on a stout shoot attain a considerable size a centimeter or more in length are closely appressed to the bearing axis, and are produced below into a stout divergent spine 3 to 7 mm in length. This rigid spine must certainly be of use in climbing in the plant's native habitat.Twining is, in a certain sense, predestined. A shoot coming thru the ground with a diameter of more than 2 mm is almost certain to become a twiner. I have not seen shoots more than 4 mm in diameter. Should a twiner find no support to enable it to rise, it wanders about over the earth, or plant growth, as do other climbing plants, its cord-like stem of 2 or 3 meters length wholly destitute of any appendage except for the spinous nodal scales.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
