My inducement to stop at Plélau was 
the neighbourhood of an extensive forest, 
and on the 18th I walked to the nearest 
part of it, lying beyond a little hamlet, 
called Le Gué, and traversed a variety of 
open heath, close wood, grove, and thicket, 
dry bank, and peaty bogs, among Oaks and 
Birch, Pine and Alder, without making 
any addition to the species I had already 
found in Brittany. Erica ciliaris and Lo- 
belia urens grew in great abundance. 
There were also Centunculus minimus, 
Exacum filiforme, Juncus Tı enageya, Py- 
rus Aucuparia, and the thorny variety of 
P. communis. 
On the 12th I walked along the road by 
which I had come, for about three miles, 
as far as the little brook which separates 
the Department of the Morbihan from that 
of the Ille et Villaine, whose course I 
traced upwards for some distance, and this 
led me into a much wilder country than 
that of the previous day, among rocky 
ground and higher hills. The plants were 
in general the same, but I added Galeop- 
sis villosa, Vicia lutea and Lolium multi- 
Jlorum and temulentum among the corn; 
Verbascum Blattaria, Juncus pygmeus, 
Illlecebrum verticillatum, and Exacum fili- 
forme grew in the dry ditches which bound 
the road; Hypericum linearifolium abun- 
dantly among rocks and bushes on the East 
side of the valley. I was highly delighted 
with the latter, and though on consulting 
Desvaux, my transports were a good deal 
tranquillized by the expression “ plante 
assez commune," I still value it as one of 
the great prizes of my journey. QZnanthe 
apufolia? in the brook which I followed, 
seems to grow exclusively in the water; 
the involucrum is often wanting, and there 
is some difference in the general appear- 
ance, and in the shape of the leaves, How 
far these marks may suffice to distinguish 
it from O. crocata, I do not know—the 
yellow juice is alike wanting in both. My- 
riophyllum alterniflorum grows also in the 
brook, perhaps not differing specifically

found for the first and only time in my life, 
on the banks of the upper pond of the 
Iron Forge. 
On the 13th I went to Rennes, and on 
the 14th to St. Malo. The Lobelia urens 
may exist in the country, but it is no longer 
so abundant as to be observable on the 
road-side, and Verbascum virgatum has 
given place to V. pulverulentum, which I 
had not before noticed since it came into 
flower, though I had observed the leaves 
of it at St. Nazaire, and I think it is either 
uncommon or not found in Finisterre. The 
packet sailed next morning, and not being 
willing to stay a week at St. Malo, I know 
nothing of its botanical productions. 
We left St. Malo at half-past six A. M., on 
the 15th of July, and arrived at Jersey at 
half-past ten. The plants of this island have 
always been enumerated in the Engli 
Flora, which thus gave them additional in- 
terest with me, and as such many were worth 
observing and collecting, which in Brittany 
I should have passed over almost without 
notice. I gathered two plants on the shore 
at a very little distance from the town, 
which have not hitherto found a place in à 
the English Flora, and thus my attention : 
was greatly stimulated as to what the island — 
might produce. I saw here T; richonema 
Columne. This, with the Helianthemum 
guttatum, grows in the greatest abundance 
on the top of the seaward slope of the hills 
beyond St. Brélade. The same situation 
affords Juncus capitatus and Lotus hupe 
dus. Schenus nigricans, beyond St. Bré- 
lade's bay. „Scirpus tenuifolius, St. Orr 
ews Pond. Knappia agrostidea, on the 
sands. Aira canescens, sands of St. Bré- 
lade’s Bay, and on the Quenvais. Briza 
minor, corn-fields, common. Cynosurus 
echinatus, on the hill on which Fort Re- 
gent is placed. Festuca uniglumis, com- —
