vessel, five petals. Filaments united at the base into three or 
five sets. 
A very pretty genus, (and the only one in the class Poly- 
adelphia,) first shewing its bright yellow flowers in this 
month. ‘There are eleven species known, of which I shall 
mention the most common. 
Hypericum catycinumM. Large-flowered St. John’ s-wort. 
I mention this, not that it is commonly found wild, though 
it is said to be naturalized in Wicklow and Cork, and also 
in Scotland, but because, being cultivated in shrubberies, it 
may therefore be known to the reader, and thus the character 
of the genus be impressed on the mind. Its flowers are very 
large and solitary, and of a beautiful yellow. The five sets 
of stamens in the centre make it very handsome. ‘The 
leaves are oblong, and the stem shrubby, branched and 
square. 
HYPERICUM QUADRANGULUM. Sguare-stalked St. John’ s- 
wort. Frequent in moist pastures, sides of ditches, and 
rivulets. Stem herbaceous, four-angled, somewhat branched, 
leaves oval, with transparent dots seen when held to the 
light. Calyx leaves, long and narrow, flowers yellow, in a 
cluster at the top. Stem from one to two feet high. 
HYPERICUM PERFORATUM. Common perforated St. John’ s- 
Y
