CYCADALES [CH. to surviving species to be included with them in one class, exhibit features regarded by many botanists as indications of an affinity either to true Cycads or to some generaKsed stock of which they are an offshoot. The Cycads of to-day may fairly be spoken of as anachronisms, plants appropriate to a former age but out of harmony with the present. They are confined to tropical and sub-tropical regions in both the old and new world. In habit. Fig. 377. Cycas circinalis. From a photograph taken by Mr A. Malins Smit

Malins Smith at Teldeuiya (Ceylon). many of them resemble tree-ferns, but the columnar stem, which may hve to a great age and attain a height of 20 metres, differs from that of ferns in its gradually tapered form consequent on the presence of one or more cambial cylinders. Though often unbranched (fig. 377) branching of the main trunk is by no means.
