Haivlea pulcherrima, Corda, Flora protogaza, pi. lvii. figs. 7, 8, 1845. 



I have already stated my belief that H. pulcherrima is a fruiting specimen 

 of Pec. Miltoni, Artis, sp.* Stub, gives as the difference between the fruit of 

 H. pulcherrima and Pec. Miltoni, that the former has shorter and broader 

 pinnules {Tertiardbschnitte) and shorter and broader sporangia than Pec. 

 Miltoni, where the pinnules and sporangia are narrower and longer. The fern 

 being so polymorphic, and the form of the pinnules so greatly depending on 

 their position on the frond, render this difference in form as a specific character 

 in the case under discussion quite valueless. In regard to the other supposed

distinguishing character — the form of the sporangia, — the slight differences 

 pointed out by Stue are far too slight to be of real value : they are even scarcely 

 distinguishable in his text figure which illustrates this point, j and entirely 

 disappear when H. pulc/wrrima is compared with Zeiller's figures of the fruit 

 of Pec. (abbreviata) Miltoni.^ 



I give a text figure (5) of a specimen from the Forest of Wyre, Worcester- 

 shire, in the collection of the British Museum, which appears to me to be at 



* Catalogue of Palceoz. Plants, p. 121. In the remarks here appended to Pec. Miltoni I have 

 inadvertently referred to H. pulcherrima as Hawlea " elegans." I have also (p. 256) referred A. 

 aquilina, Geinitz, Vers. d. Steinhf. in Sadism, pi. xxxi. figs. 5-7, to Pec. Miltoni. I still think it pro- 

 bable that his figures 6, 7 are referable to this species, but am more doubtful about his figure 5. They 

 are therefore omitted meantime from the synonymy of Pec. Miltoni, Artis, sp. 



t I am indebted to Dr Woodwart, F.R.S., for permission to describe this specimen.
