S6 Notes on Lastrea remota {Moore). [Sess. 



about it. This is extracted from the Proceedings of the 

 Linnean Society, read by Mr Moore on 15th December 1859. 

 In the course of the last summer Mr F. Clowes of Windermere 

 sent me a frond of a fern found by him in the Westmorland 

 Lake district, doubtfully labelled Lastrea Filix-mas var. incisa, 

 and he observed that for some years it had been considered to 

 belong to L. spinulosa. A specimen subsequently sent when 

 in a more developed state led to a comparison with L. remota 

 of Braun, for a frond of which I am indebted to Professor 

 Mettenius of Leipzig, and this comparison proved the German 

 and Westmorland plants to be of the same kind. 



I shall now give you Mr Moore's description of the plant : 

 " Lastrea remota — Fronds oblong - lanceolate, subtripinnate, 

 smooth ; pinnae acuminate, distant below, pinnules distinct, 

 pyramidal or ovate oblong, acute, shortly petiolate below, 

 sessile, with a narrow attachment, or more or less adnate 

 upwards, the basal ones pinnatifid almost to the costa ; lobes 

 oblong, blunt, serrated, the serratures acute mucronulate ; sori 

 copious over the whole frond, biserial near the costa ; indusium 

 reniform, obscurely eroso-dentate, persistent without glands ; 

 stipes and rachis stout, scaly. Hab., Windermere. F. Clowes, 

 1859." 



I am sorry, however, that I am unable to lay my hands on 

 Professor Braun's description of the plant, which would have 

 been most interesting, as he was the first to discover the plant 

 as well as to describe it. I have, however, got a short notice 

 by Professor Braun of his discovery of L. remota, extracted 

 from ' Botanical and Physiological Memoirs,' edited by Arthur 

 Henfrey, F.E.S., F.L.S. : "I myself found in the year 1834, 

 in a mountain valley near Baden, among Aspidium Filix-mas 

 and A. spinulosum (the normal form together with the variety 

 dilatata), several rhizomes, all within a small space, of a fern 

 which stood about midway between the two species named, 

 and probably was to be regarded as a hybrid product of them. 

 I called it Aspidium remotum, and formerly regarded it doubt- 

 fully as a variety of Aspidium rigidum, which it resembled 

 not only in habit, but in degree of formation and mode of 

 decrease of the pinnae. I have never since been able to find 

 it again, either in the original station or anywhere else in 

 the Black Forest, but it has been maintained in existence in
