FOSSIL FLORA OF THE STAFFORDSHIRE COAL FIELDS. 171 



I am not, however, certain of this, though I do not think there are three veins as in 

 Dicranophyllum gallicum Grand'Eury.* 



The arms of the first dichotomy show two marginal veins, but these may arise from 

 a dichotomy of a single vein at their base, though I cannot trace this clearly ; but in 

 the case of the fourth dichotomy of the leaf it is clearly shown that the single vein 

 which enters the segments is the result of a dichotomy of the vein at the extreme base 

 of the segment from which they have originated, where they show as marginal veins 

 before one passes into each of the ultimate segments of the leaf. 



The rhomboidal form and much-divided leaf will easily distinguish Dicranophyllum 

 anglicum from the already known species. A leaf enlarged 2 times is given at 

 3a. I am indebted to the late Mr D. Rogers for this specimen, from whom I 

 received it in 1887, but have delayed describing the plant in the hope that additional 

 examples might be discovered, but such, as far as I am aware, has unfortunately not 

 been the case.
