Blume compares this remarkable species with P. vulgare : 
but in form and texture it is widely different. Its sori, too, 
are sunk into a deep pouch or bag, forming so many pro- 
minent papillse on the upper side of the frond, the mouth of 
which is contracted. Blume notices a var. “B. frondibus 
brevioribus et laciniis acutiusculis.”
