According to O.M.B. Bulman (1970), the Dendroidea
are sessile graptolites, "attached by apex of sicula,
which is the generally more or less embedded in
secondary cortical tissue forming a rootlike base, or
more rarely attached by a nema; stipes composed of
stolothecae, autothecae, and bithicae produced by
regular triad budding; rhabdosome typically erect,
dendroid in habit of growth, developed by dichotomaus
or irregular branching, with anastomosis or
dissepimental connection between adjacent stipes in
many forms; pendent to horizontal (very rarely riclined)
in forms with nema attachment."
Middle Cambrian - Carboniferous, ?Permian.
