Chlora perftoliata, tjie only British species of the genus, is found throughout the warmer parts of Europe,
with us abound? in chalky pastures and corn-fields. Box Hill in Surry and the chalk-hills of Kent produce
mis pretty annual in considerable plenty; and it has this year (1815) been seen in the vicinity of London in un-
usual prolusion. Nor is it by any means uncommon on the stiff clays of Norfolk and Suffolk, adorning the fields
n lts yphow blossom during the months of August and September. Our figure, it may be well to remark represents
the plant rather drawn up, from having grown amongst low underwood.
