Calamocladus type 1 , but its occurrence in Britain is uncertain. 
Kidston 2 thinks that possibly cones of this species have been included 
under the name of Calamostacliys typica, Schimper, together with a 
Palceostachya. The foliage of Stachannularia northumbriana Kidst. 
is unknown, while the cones of Calamocladus lycopodioides (Zeiller) 
and Annularia galioides, Lind, and Hutt. do not seem to have yet 
been recognised. 
Hitherto, it has not been definitely known which impressions 
correspond to the petrified species Calamostacliys binneyana. Dr. 
Kidston 3 has already regarded Paracalamostachys williamsoni as 
identical with Binney’s cones, though Weiss 4 states that it differs
