Remarks. The fruiting example of Pecopteris Miltoni from the Forest of 

 Wyre, both in the general outline of the fern and in the arrangement of the 

 sporangia, agrees in all respects with Corda's figure of Hawlea elegans, only 

 in the British specimen the fruit is somewhat more perfect. I have therefore 

 united this species with Pecopteris Miltoni. I also include here Pecopteris 

 crenata, Presl., which does not differ from P. Miltoni in any appreciable 

 manner.
