it seems to be one of those anomalous things of which the systematic 
place is at present rather doubtful. 
I may here also mention that Collema chalazanodes, Nyl. in Flora, 
1869, p. 293, has been gathered in Bradley Wood, Devon, by Dr. H. 
D. Holl, whose herbarium contains several lichens not hitherto re- 
corded as British, which will be duly noticed in my forthcoming ‘ Enu- 
meration of British Lichens.’ 
NOTES ON THE FERN-FLORA OF CHINA. 
By H. F. Hanoz, PRD., Ere. 
At page 270 of the last volume of this Journal, Dr. Max Kuhn, of 
Berlin, notices, under the name of Woodsia macrochlena, a supposed 
new Fern, collected at Che-foo by the botanists of the Prussian expe- 
dition to China. Dr. Kuhn has since had the kindness to transmit to 
me a small specimen of this, an examination of which enables me to 
state positively that it is identical with my Woodsia insularis, de- 
scribed eight years ago (Ann. Se. Nat. 4, sér. xv. 228) from two or 
three plants only, gathered in the island of Sachalin. Dr. Kuhn re- 
marks, *differt ab omnibus reliquis speciebus indusio membranaceo 
quadrifido, lobis margine longissime ciliatis persistente." It seems to 
have escaped him that W. polystichoides, Eaton, figured by the late 
Sir W. Hooker at plate 2 of his *Second Century of Ferns' and 
plate 32 of his ‘Garden Ferns,’ is described as “involucro e squamis 
4—5 tenui-membranaceis in orbem dispositis imbricatis longe ciliatis ;” 
and by Milde (Fil. Europe, ete., p. 170), from the figure only, as 
having *indusium profunde quadripartitum, margine longe ciliatum.” 
Of the varieties nudiuscula and sinuata of this latter species I possess 
good examples from northern China, as also of W. Ilvensis, R. Br., and 
JF. hyperborea, R. Br. The sections into which this genus is divided 
by various pteridologists do not seem to me tenable 
In the article referred to, Dr. Kuhn quotes my notice of Adiantum 
Cantoniense in a way which would be likely to lead an ordinary reader 
to infer that I had maintained this as a species, and that he had first 
established its identity with 4. Capillus-Junonis, Rupr. This is not 
the case, as my paper, published a year before his own, had for its sole 
object to point out this identity. Dr. Kuhn regards the southern Fern
