96 GUERNSE Y. 
Sedum anglicum, Huds. English Stonecrop. 
Native. First record: Gosselin, 1815. 
Very common on the cliffs and the shores of the lowlands, as” 
‘well as inland on dry banks, walltops, and old thatched roofs. 
Sedum acre, L. Biting Stonecrop. Wall Pepper. 
Native. First record: Gosselin, 1815. 
Rather common generally, sometimes abundant, in sandy ground 
_all round the coast of the low-lying districts. This species does not 
appear to grow on the cliffs here, as it does in Alderney. 
The whole plant is hot and pungent when chewed, and when 
applied to the skin produces blisters. In the northern parts of 
_Normandy, both this and 5S. azg/icum are known under the name of 
Thym de Crapaud, or Toad’s Thyme. 
Sedum reflexum, L. Yellow Stonecrop. 
Alien. First record: Marquand, 1801. 
Rare. Mostly on old walls. Plentiful on an old wall at Les 
-Goubais (1x.) and at foot of the hedge nearly opposite. Also in the 
same parish at Les Rouvets, and on a roof at St. Clair. Between 
Cobo Church and Castle. Les Bourgs (vur.). Planted on a 
hedge at Mauxmarquis (11.). 
Sedum Forsterianum, Sm. 
Alien. First record: Babington, 1839. 
Very rare. On banks on both sides of a lane above L’Echelle 
Mill, Talbots Valley. On walls at Naftiaux (11.) and nearly opposite 
Le Chéne (1v.). Recently planted on a roadside hedge at Maux- 
marquis. This plant seems to have disappeared from Babington’s 
old station: ‘on a wall by the roadside leading from St. Peter’s Port 
to Grand Cobo.’ 
Sempervivum tectorum, L. FTouseleek. 
Alien. First record : Gosselin, 1815. 
Formerly common on the roofs of farm buildings, but now very 
rare and almost extinct. A few plants on the walltop above 
L’Echelle Mill, Talbots Valley. Walltop behind Richmond Hotel 
(vu.). One or two plants on a wall at La Villette (111.). 
Locally known as /Jaune barbe. The medizeval name of the 
Houseleek was /Jovis barba, or Jupiter’s beard. From this came 
the French name /ouéarve, corrupted in Normandy into Jomébarte, 
and still further altered in the Guernsey patois into the more 
intelligible, if less correct, name of Jaumne barbe, or yellow beard. 
Similarly the Houseleek is called in Germany Donnerbart, Jupiter 
being regarded there as the Thunderer. From this arose the 
belief that the buildings on which it grew were thereby protected 
from lightning. Charlemagne commanded that it should be planted
