LastrcBa spinulosa, Presl., b. exaltatum. Woods, Foxes’ Bridge, 
Forest of Dean, W. Gloucestershire, August, 1892. — Augustin Ley. 
“ Typical spmulosaP — J. G. Baker. 
L. spinulosa^ Presl. c. decipiens. Near Tintern, Monmouthshire, 
14th September, 1892. One large clump of this plant was observed. It 
appears to me to agree in every particular with the description of the 
var. decipietis of L. spinulosa in ‘Eng. Bot.’ Ed. iii. — Augustin Ley. 
L. spinulosa, var. c. decipiefis, Syme. Near Tintern, Monmouth- 
shire, 14th September, 1892. — W. A. Shoolbred. “I should have 
called this typical spmulosa ; decipiens is a glandular form.” — J. 
Gilbert Baker. “ Seems to accord with Syme’s description, except 
that I cannot find the indusia obviously dentate.” — -Arthur Bennett. 
L. spinulosa, Presl., d. glandulosa. Damp wood. Foxes’ Bridge, 
Forest of Dean, West Gloster, 4th August, 1892. If rightly named, 
an interesting rediscovery of this fern in the Forest of Dean. The 
original locality, “ Ankerbury bog,” near Lydbrook, where the plant 
has long been extinct, lies about four miles distant from Foxes’ Bridge, 
Three or four large rootstocks were observed among abundance of 
L. spinulosa, var. exaltatum, and sparing Z. dilatata, Presl. Root- 
stocks slightly creeping, but not so much so as in L. spinulosa, var. 
exaltatum. — Augustin Ley. “ This is what I understand is Z. 
spinulosa, var. decipiens, Syme.” — J. Gilbert Baker. Mr. Ley rightly 
labels his plant from the ‘ Lond. Cat.,’ but its being placed under 
spinulosa there must, I think, have been an error. The consensus of 
opinion (H. C. Watson, Newman, Moore, &c.) places it under dilatata. 
In so difficult a plant, it ill becomes me to say more than that Mr. 
Ley’s specimen does not well agree with an original specimen of Mr. 
Doubleday’s (Essex) I possess. Mr. Ley’s plant is not nearly so 
glandular, the scales in his plant are more pointed, the pinnae do not 
seem to present that peculiar upward turn that glandulosa seems to. 
With an ordinary lens, I cannot detect any conspicuous glands on the 
indusia of Mr. Ley's specimen, while Mr. Doubleday’s shows them 
very numerous, and, although the outline of the indusia in Mr. Ley’s 
plant is serrated, still I can find no stalked glands on the serrations 
as in glandulosa. Mr. Newman has been quoted as considering the 
plant as a species; but, in the ‘Phytologist,’ 1851, p. xv., he distinctly 
repudiates this idea. On the whole, I should find it difficult to label 
Mr. Ley’s specimens as glandiclosa.” — Arthur Bennett. 
Polypodium vulgare,, L. var. serratum, Willd. Knock Ross, Co. 
Westmeath, 17th June, 1892. — H. C. Levinge. 
Equisetum limosum, L. var. polystachion, A. F. Briick. ‘ FI. Neob. 
Prod.’ (1803) p. 63. Marsh, near the Caledonian Canal, Westerness, 
Aug., 1891. Necessarily this form belongs to E. flumatile, L. It 
is a state rather than a true variety, but one which I have not pre- 
viously seen in Britain. The swamp in which it grew was being 
drained and this diminished moisture may have caused it to assume 
this form, but the almost daily rain of that wet summer does not 
support the argument strongly. — G. C. Drrce.
