Spec. Char., fyc. Stem shrubby, round, erect, branched. Leaves elliptical-lanceolate, acute, with 

 glandular margins, and pellucid dots. Calyx lanceolate, acute. (Don's Mill., i. p. 609.) A sub- 

 evergreen undershrub, native of Madeira and Teneriffe, introduced in 1777 ; producing its pale

Spec. Char., fyc. Stem suffruticose, round. Leaves ovate, obtuse, on very short petioles, with revolute 

 margins. Calyx ovate, obtuse, fringed. (Don's Mill., i. p. 610.) A neat little bush, which has been 

 in cultivation as a half-hardy shrub since 1688. It produces its yellow flowers in July and August, 

 and grows to the height of 1| ft. It is well adapted for culture in pots ; or on the warmest part of

Petals without glands. (Don's Mill., i. p. 610.) A neat little shrub, a 



native of the south of Europe, particularly near the Mediterranean ; 



introduced in 1820, and producing its yellow flowers from May to 



August. Height 2 ft. This is one of the neatest species of the genus, 



and it well deserves a place on the hypericum mount, suggested 



under H. oly^mpicum, p. 399., because it is not altogether hardy. As 



it is a slow-growing plant, and small in all its parts, it should not be 



placed immediately adjoining any of the rapid-growing, broad-leaved, 



or bulky species, unless required in the way of contrast. It would 



suit very well to accompany H. baleiricum, H. ericoides, and H. 



Cbris, which are also half-hardy species.
