each other in their upright or diffuse stems; 
but as nothing is said of this in C. virens, 
we may suppose it to vary in that respect. 
Desvaux cites the C. diffusa of De Can- 
dolle as a synonym of C. virens, and as- 
signs to it pinnatifid root-leaves. Of C. 
stricta, though he quotes De Candolle, he 
says that his plant differs from the one of i 
that author, without stating in what respects. 
He gives, however, what may be a very 
good guiding character, though not a spe- 
cific difference, that the rays are yellow on 
both sides, and not reddish externally. 
Yet I find this sometimes in Crepis virens 
at Lewes. To his C. Dioscoridis he cites 
C. virens of De Candolle, of which the 
stem is bristly (herissé) at the base. As 
the plant occurs in Brittany, it is often 
hairy at the base; but I never saw it bris- 
tly. C. scabra I do not know. 
After my walk I went to the public li- 
brary, which is open every day except 
those of fétes, from twelve to four, in order 
to examine the Herbarium of Mons. Bonne- 
maison. It is in great confusion, and it 
seems as if nothing could be learned from 
it without a detailed examination of the 
whole. large portion consists of Alge, 
to which he had paid particular at- 
tention; they are from all parts of the 
world, but arranged (so far as there is any 
arrangement) according to an unknown 
system of his own. The manuscript, how- 
ever, is said to be in existence, but is not 
in the library. The other packets which I 
opened were principally, but not exclusive- 
ly, plants of Brittany, or of France. I ob- 
served Andrea alpina, which is merely 
said to grow on rocks and stones, but there 
are Bréton habitats for A. Rothii and A. 
rupestris. Among the bundles of flower- 
ing plants which I hit upon, there was one 
containing the twenty-first, twenty-second, 
and twenty-third classes of Linneus, with 
the addition of the Ferns. This contained 
Ophioglossum Lusitanicum, from the Isle 
of Ouessant, Grammitis leptophylla fro 
Brest, St. Pol, and Pourviers; Urtica 
membranacea from Pourviers, and U. pi- 
lulifera from Le Conquet. In the after- 
noon I went to Pont L’Abbé, and the next
