Specific Character. — Glaucous. Leaves perfoliate. Stem dicho- 
Description, &c.— This plant, though a native of Britain, requires so much care to cultivate it, that it is 
very seldom grown ; though it is so pretty that it well deserves to become a garden flower. It requires an open 
hilly situation, and a loamy soil, with a substratum of chalk or limestone ; and without these advantages it 
seldom succeeds in the open garden, though it may be grown tolerably well in calcareous soil and in well- 
drained pots. Chlora is from the Greek word Chloros , pale. 
C. IMPERFOLIATA, Lin. 
This species differs from C. perfoliata in the leaves being not perfoliate; they are said to be perfoliate 
when the stem appears to pass through them, like the leaves and stem of the common honeysuckle, C. aprifolium 
imperfoliata. It is a native of Italy, and was introduced in 1823.
