$2 The Rev. Hucır Davızs’s Remarks on Lichen scaber 
mis.” English Botany has this: “Shrubby, filamentous, much 
branched, intricate, round,. solid, smoothish, brownish black, 
shields of the same colour, flat, with an irregularly toothed 
margin." ES CIN | j 
These descriptions are certainly characteristic, with the ex- 
ception only of the word “caulescens” in the one, and * shrubby” 
in the other, of the two latter, wherein a confused glance of 
L. bicolor seems to obtrude itself on the true lanatus.. 
Acharius's definition of his L. lanatus, when referred to this 
figure, being, as I have observed, accurate, it is. no wonder, 
when he quotes f. 8. t. xiii. for the same, that he should say, 
* Icon minus bona," whereas it is an excellent representation. 
ef the plant which it is intended for, viz. L. bicolor, if we except 
indeed one impropriety, I mean its procumbent appearance'on 
the plate, which may tend to mislead, as the plant is invariably 
upright, as I have seen it in Anglesey and Caernarvonshire, and. 
has a shrub-like appearance. — — 
"These two species being, I trust, satisfactorily settled, I will 
now proceed by observing, that I am enabled to afirm, after an 
attentive and strict examination of the very plant which Dille- 
nius received from Greenland, and which is marked with his 
own handwriting as such, that f. 9. t. xiii. is the very same species. 
with f. 32. t. xvii. This Linnwus refers to for his L. pubescens, 
and consequently Lightfoot is right in referring to 32. xvii. 
for that same species. But as we have just now seen that 39. 
xvii. is the true L. lanatus, it will follow that 9. xiii. beine 
the same plant, L. pubescens, as a species, proves to be nobod 4 
And so far the above-named authors, Prof. Acharius and Dr.. 
Smith, are right in quoting the two for the same species as Lı-.
