 Remarks. The type specimen, as figured by Brongniart, shows the ribs on 

 the stem fully 1| inch wide, while the leaf -scars are only about | inch in 

 transverse diameter. 



This plant is very plentiful in the Kadstock Coalfield, where I have 

 examined many examples. In the younger condition, when the ribs aie 

 about \ inch in width, the scars are about j inch in diameter : from this stage 

 one can trace the growth of the ribs in width, but little perceptible enlarge- 

 ment in the size of the leaf -scar takes place.
