Type-specimen. Newcastle-upon-Tyne Museum. 1 The available 

 material is insufficient to enable us to give a satisfactory diagnosis 

 of the species. The frond was probably bipinnate ; the large, 

 broadly linear pinnules have the Cladophlelis type of venation ; 

 they are attached at almost a right angle, and differ from those 

 of C. denticulata in being straighter and not falcate. There are 

 no specimens in the British Museum Collection which can be 

 reasonably referred to this species. A solitary example in the 

 Leckenby Collection, Cambridge (No. 80), agrees exactly with 

 the specimen figured by Lindley & Hutton. It is possible that 

 Cladophlelis haiburnensis is not a distinct species, but the general 

 appearance of the Leckenby specimen hardly favours its inclusion 

 in any of the other species of Cladophlelis or in Todites Williamsoni. 

 There is a striking similarity between C. hailurnensis and a specimen 

 named by Heer Asplenium whitliense tenw?
