The stems of cycads are often described as unbranched; it is true that in comparison with conifers, in which the numerous branches, Stem springing from the main stem, give a characteristic form to the tree, the tuberous or columnar stem of the Cyca daceae constitutes a striking distinguishing feature.
The tentacles may number many hundreds or may be very few, in rare cases only one or two, or even absent altogether; they may be long and filamentous, or short and reduced to mere knobs or warts; they may be simple and unbranched, or they may be feathery in pattern.

There are two main groups, or sub-phyla: the Graptoloidea or Graptolites proper, and the Dendroidea or tree-like Graptolites; the former is typified by the unbranched genus Monograptus and the latter by the many-branched genus Dendrograptus.
