bourhood of Snowdon, I am inclined to think it probable he was 
deceive! by some old flowers of Erica vulgaris falling among the 
Sphagnum. 
FONTINALIS. 
No. 2. Fontinalis minor, Linn, agrees exactly with specimens of 
Hedwig's Trichostomiimfontinalioides sent me from Germany. 
HYPNUM. 
No. 4. Ilypnnm acacioides, Linn. — I could find no difference, 
except in the shortness of the peduncles, a circumstance most 
probably accidental, between this and Mr. Dickson's II. asple- 
nioides. 
6. H. sylvaticum, Fl. Ang. seems, as Hedwig suspected, to be 
merely a variety of the preceding number (H. denticulatum, Linn.); 
and No. 9- differs in nothing but its darker colour. This last Lin- 
naeus described in the Species Plant arum under the name of H. or- 
nithopodioides, but evidently depended wholly upon Dillenius. 
19. A., which Hedwig supposed to belong to his It: crista 
eastrensis, appears to be his ll.Jiliciiium, and B. CD. E. F. his 
II. commutatum : but I speak with much diffidence, not being at 
all convinced that I understand the specific difference between 
these plants. 
20. Dillenius has under this number joined Hedwig's II. crista 
eastrensis, and molluscum ; the former sent him by Haller, the 
latter found in England. Linnaeus, Hudson, and others refer all 
this number to their II. crista eastrensis; but it certainly includes 
two very distinct species. 
24. Reference is made in the Species Muscorum to A. and B. of 
this number only under H.rugosutn; but by the Herbarium, Mr. 
Dickson appears to be clearly right in referring the whole to thut 
species.
