 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,

 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. ol^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 \,~$S** *~v^ / WJ 

 placed immediately adjoining any of the rapid-growing, broad-leaved, e J^fjty>/{5 l/jj/ '' " 

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

 suit very well to accompany H. balearicum, H. mcoides, and //. 

 Cbris, which are also half-hardy species.
