Observations on some British Plants. 473 



posed to repeat many of them. Thus, without better authority 

 than seeing the names in a foreign Flora, I cannot assert that 

 either Primula scotica, Hook., or Saxifraga pedatifida, Sm., are 

 found abroad : nor could I, even now that my attention has 

 been called to them, do more than introduce by name such 

 plants as Thlaspi virens, Achillcea tanacetifolia, or Carex brizoides, 

 having seen no specimens from England, — having no evidence 

 that the plants found were correctly named — and as little that 

 they were truly indigenous. As to Carex aquatilis not being 

 the plant of Wahlenberg, allow me to state that we have merely 

 given Dr. Boott's opinion, stated in a former edition, and have 

 not expressed one that the Clova plant is C. caspitosa of Fries. 

 It is known to all that Fries says his C. caspitosa was sent 

 him by Dr. Greville from Scotland : the species itself is not in 

 Dr. Greville's herbarium ; and therefore there is a strong pre- 

 sumption that Fries, misled perhaps by the specimen being im- 

 perfect, had called by that name something known to us by a dif- 

 ferent one : many things indeed concurred to make an impression 

 on my mind that Fries had only received our C. aquatilis. With 

 regard to the fruit of C. caspitosa, Fr., being described by us 

 acute instead of obtuse, the writer is perfectly connect in supposing 

 that in the temporary absence of Fries' work, I trusted to 

 Mr. Babington, whose accuracy I had proved in almost every 

 other case. 



In addition to this error there are some others of as grave a 

 nature, omitted in the list of errata : thus, 



P. 80, 1. 8, /or "base " read " back." 



P. 92, 1. 2 from the bottom, after "nearly equally" add 

 " but obliquely " ; for the mouth of the calyx of Anthyllis vul- 

 neraria is oblique, but the teeth are nearly equal in size. 



P. 534, 1. \l,for "winged" read "unequal." 



There may Jbe many others. 



Upon Lastrea, or Aspidium dilatatum, and its allies, I may 

 perhaps make some observations at a future period : in the mean 

 time I may state that I possess Nephrodium fomisecii, Lowe, 

 from Lowe himself, and it is clearly not the form or species 

 called Lastrea recuita by Newman, nor does Lowe's description 

 tally with our plant, which was detected in the Isle of Arran 

 (Scotland) twenty years ago, by Mr. Steuart Murray of the 

 Botanic Garden here, and is perhaps, as first observed by Dr. 

 Balfour, more decidedly known by a section of its root or lower 

 part of the stipes, than by any of the characters yet proposed. 

 The 'Fng. Bot.' Aspidium spinulosum, or the plant from Spike 

 Island, is to me as yet doubtful : it is evidently, however, not 

 the form so called in England, but whether it ought to be 

 referred to Lastrea dilatuta or L. recurva, Nev.m., I could not
