FLOWERING PLANTS. 83 
ROSACEAE. 
Prunus spinosa, L. Blackthorn. Sloe. 
Native. First record: Gosselin, 1815. 
Common throughout the island. In 1894 it was already be- 
ginning to flower on March 3rd at Moulin Huet. I have noticed 
the var. fruticans at Moulin Huet, and here and there at the Vale 
and Catel: probably it is not uncommon. 
The patois name is /Véve Hpeine, the local form of the French 
pine noire. White, of Selborne, says the Blackthorn ‘usually 
blossoms while cold north-east winds blow, so that the harsh, rugged 
weather obtaining at this season is called by the country people 
Blackthorn winter.’ 
Prunus insititia, L. Bullace. 
Native. First record: Marquand, 1891. 
Rare. Several trees above Divette Cove, below Doyle’s Monu- 
ment. Also several on the steep bank of the road leading down to 
Fermain Bay. Mr. Andrews has noted two small bushes by the 
roadside at Sausmarez, St. Martin’s, and several in a hedge on the 
road to Doyle’s Monument. 
Prunus domestica, L. Wild Plum, 
Denizen. First found: Miss Dawber, 1887. 
In the Report of the Watson Botanical Exchange Club for 
1887-88, the following note occurs: ‘Prunus domestica, L. 
Moulin Huet, Guernsey, May, 19, 1887, M. Dawber. Mr. Baker 
thinks it may go under P. domestica, but shading off towards znsititia. 
A. Bennett.’ In 1900 Mr. C. Andrews found this species growing 
abundantly on both sides of the path leading down to Moulin Huet, 
below the Vallon grounds: evidently the same station. 
_ Prunus Cerasus, L. Dwarf Cherry. 
Denizen. First record: Babington, 1839. 
Upper end of Talbot’s Valley. Lane by St. Andrew’s Rectory. 
Hedge opposite St. Andrew’s brickfield. Near Ozanne’s Tower. 
Near Les Fauxquets (vi.). This species is probably the Prunus 
Avium, Common Wild Cherry, of Gosselin’s list. “There is no 
evidence of the occurrence of the true P. Aviwm in the Channel 
Islands. 
Poterium Sanguisorba, L. Salad Burnet. 
Native. First record: Gosselin, 1815. 
Local. Plentiful on Lancresse Common on the western side, 
and towards Lancresse Bay; but the plants are somewhat scattered. 
The leaves of this plant, which taste something like cucumber, 
were used formerly in the preparation of a beverage called ‘cool 
tankard ;’ hence the name /o¢erium, which signifies a drinking-cup-
