 Mount Pive-zend, between Shiraz and Kazeroum, Aucher-Eloi, n. 5488. 

 Caves in the Island of Kareh^ Persian Gulf, and at Dalechy, Kotschy, n. 

 10 and 198. — A small and very distinct species, long knowu to that Chief 

 of Botanists, Mr. Brown, and named by him, without description, in the 

 Appendix to Salt's Abyssinian travels. More recently it has been taken up 

 and both described and fi<>:ured by continental botanists, 1st, as Allosorus 

 melanolepis, Dene. ; and 2ndly, as Allosorus cuspidatus, Hochstetter. By 

 Kunze it has been properly referred to Onychium. It is a plant of very 

 delicate texture, like unusually slender specimens of Gymnogramma lep- 

 tophylla. 



O. Krebsii, Kunze, in Linnoia, x. p. 504, fi-om Graham's 

 Town, South Africa, proves to be a Scolopendrium, accord- 

 ing to the same author, on an examination of more perfect 

 specimens, and the error has since been corrected in the 18th 

 volume of the ' Linnaea,' and in the Supplement to Schkuhr's 

 * Filices,' where it is figured and described as Scolopendrium 

 Krebsii. 



O micropterum, Hook. — Under this name, in the 'Genera 

 et Sp. Fil.' I referred to a plant of the late Capt. Carmichael 

 in ray Herbarium, bearing the name of Lomaria microptera, 

 Br. (MS.) It is with regret I am compelled to say that the 

 plant is no longer to be found in my Herbarium, acciden- 

 tally mislaid probably : so that I am unable to describe it 

 and to offer any further opinion respecting it. Kunze in- 

 cludes it in his Catalogue of the species of Onychium ; but 

 only on the above authority.
