87. FILICES. 601 
Lastrea (Filix mas) abbreviata, Newm. Hist. 
Provinces - 10 11. Ingleborough Hill, York. Teesdale, Durham. 
Syn. 1387. This fern is not known to me. Newman's beautiful 
work, the ‘ History of British Ferns,’ is conveniently referred to 
for the three varieties of Filix mas; but it should be mentioned 
that he has them under the generic name of Dryopteris, not that 
of Lastrea. It is curious to note the discrepancies in the generic 
name adopted for this common fern by our three chief living 
Authors of British Floras; Aspidium, by Bentham, Nephrodium, 
by Hooker, Lastrea; by Babington. Of course Mr. Newman must 
look about for a different generic name, one not so likely to be 
adopted in books more strictly botanical. So again, in their turn, 
for the under-mentioned Lastreas or Aspidiums or Nephrodiums, 
the new name Lophodium is invented. Great as have been the 
services of Mr. Newman, in elucidating our British Ferns, he has 
gone far towards outbalancing them, by the great dis-serviee of 
adding a number of new and needless names to our super- 
abundant supply. 
Lastrea (cristata) uliginosa, Newm. Hist. 
Provinces -- 3 4---89. [15. Kincardine, erroneously.] 
Syn. 1389. Cyb. iii. 269. See page 455, for some remarks on 
this fern. Approximates to spinulosa in its cutting. 
Lastrea (dilatata) glandulosa, Newm. Hist. 
Provinces - - 3-5. Essex. Gloucester. [10. York]. 
Syn. 1891. This stands between dilatata and spinulosa, not 
satisfactorily assignable to either by the dried specimens alone, 
and I have not seen the plant alive. As in the case of uliginosa, 
it presents the difficulty of an intermediate form, the dried fronds 
of which might be united with either, or made into a species not 
clearly distinguished from either. LL. dilatata has been sent to me 
labelled “glandulosa” by a good botanist; I do not know that 
any one ever so labelled an example of spinulosa. , 
Lastrea (dilatata) collina, Newm. Hist. 
Provinces - 10-12. York. Westmoreland. 
Syn. 1391. A variety known to me by description only. 
Lastrea (dilatata) nana, Newm. Hist. 
Provinces -23---78910-12--15. 
Syn. 1891. This is the Aspididum dumetorum of Smith, as 
explained on page 456. But the name may be intended also to 
cover a wider range of form than Smith’s dumetorum ; for Mr. 
Newman states that his nana is found in the woods of Sussex and 
Kent. Of late years, I have sought and collected fern roots 
numerously in Surrey and the adjacent portions of Sussex and 
Hampshire, but have never met with anything at all corresponding 
with Newman’s figure of nana (originally given for dumetorum) or 
4u
