Spec. Char.,fyc. Stem round. Branches angular. Leaves 

 linear-lanceolate, with revolute edges, full of pellucid 

 dots. Corymbs few-flowered. Sepals ovate-lanceolate, 

 stamens very numerous. Styles usually connected to- 

 gether. (Don's Mill.) A sub-evergreen shrub. New 

 Jersey to Florida, in swamps. Height 1 ft. to 4 ft. In- 

 troduced in 1758. Flowers yellow; June to August. 

 Capsule reddish brown ; ripe in October. 117. 



Frequent in gardens, and forming a dense leafy bush, covered with flowers 



great part of the summer, and with seed-pods in the autumn. Readily 



distinguished from H. Kalmidnum, by the leaves, bracts, and sepals being 



much smoother and shining. 



B. Sepals toothed, usually with the Teeth glandular.

 (Don's MilL) A neat little evergreen shrub. South 

 of Europe, near the Mediterranean ; and in Greece. 

 Height 1 ft. to 2 ft. Introduced in 1820. Flowers

One of the neatest species of the genus, but some- 

 what tender.

Other Species of Hypericum. The only truly hardy shrubby species of 

 jF/ypericum are, H. elatum, H. hircinum, H. calycinum, H. Kalmidnum, and 

 H. prolificum. The other hardy species are of such low growth, that they 

 may be considered, for all practical purposes, as herbaceous plants. H. 

 ncpalense Royle appeared to be hardy in the Hort. Soc. Garden, but it was 

 destroyed by the winter of 1837-8. H. adpressum Bartr., H. rosmarinifolium 

 Lam., H. galwides Lam., H. fasciculdtum Lam., and some other shrubby or 

 frutescent species, are described by Torrey and Gray, but we are not aware of 

 their having been yet introduced.
