| notes: | Large typed note bottom right -------------------------------------------------------------------- Lastaea spinulosa, Prel, var. glandulosa (Moore). Boggy wood, Pont Esgob, Herefordshire, 28th August 1901. In the character of the scales, and the glandular development of the under surface of the frond, this seems to me to represent Moore's plant very well.--Augustin Ley. "I cannot name this so. I have an original specimen of it from Doubleday (Epping Forest); and that has not only the stipes densely covered with glands, but the pinnae are so densely glandular as actually to seem to add to their thicknes! I do not consider Mr. Ley's [plant from] Haugh Wood, Herefordshire, 3rd September 1891, as glandulosa either. On Mr Ley's [plant from[ Treven Glen, near Defyog, Brecon, 31st July 1899, Mr. J.G. Baker has noted: 'This is not exactly Newman's original glandulosa, which has sharper teeth and is more densely glandular.' And why does he quote Moore? Newman described it in 'Phytologist' iv. p.256 (1851): 'Attempt to characterise another apparently undescribed species of Lastraea, by Edward Newman.' In his 'British Ferns,' ed.3, 154(1854), he names it 'Lopodium glandulosum.' In this book he had the genera-splitting craze on, of which Watson said: ' I shall declare war against it.' It is L. dilatata, var. glandulosa, Moore ('ex parte,' teste Syme), 'Handb. Brit. Ferns,' ed. 2, 124, ed. 3, 127; Nephrodium dilatatum, var. glandulosum, Hooker, 'Stud. Fl.,' 466. Syme in 'Eng. Bot.,' ed. 3,vol. 12, p.82 (1886), says: 'I cannot help suspecting that L.glandulosa is a hybrid between L. spinulosa and L. dilatata. Were it abundant as either of the two instead of being very scarce, we might consider it as a form from which L. spinulosa on one side and, L.dilatata on the other, were diverging; and the same might be said of L. uliginosa, from which L. oristata diverges in one direction and L. spinulosa in the other; and, lastly, we have L. remota, which connects L. spinulosa, or (as seems to me more probable) dilatatam wuth L. Filix-mas.'''--Ar.Bennett. "Mr. Ley has evidently taken the nomenclature of 'Lond. Cat.,' ed.9, p. 46, for granted" --Ed. -------------------------------------------------------------------- |
