120 HYPERICACE^E. 



*** Styles 3. Sepals fringed with glands. 



7. H. montdnum (Mountain St. John's Wort). Stem 

 erect, round, smooth ; leaves oblong, sessile, smooth, with 

 glandular dots near the margin ; sepals acute, fringed 

 with shortly stalked glands. Limestone hills, not un- 

 common ; growing about 2 feet high, and remarkable 

 for the black fringe of its sepals, which at once dis- 

 tinguishes it from any of the preceding species. Fl. 

 July. Perennial. 



8. H. hirsutum (Hairy St. John's Wort). Stem erect, 

 nearly round, downy ; leaves downy. Woods, especially 

 in a chalky or limestone soil ; about the same size as 

 the last, but well marked by its downy herbage. Fl. 

 July. Perennial. 



9. H. pulchrum (Small upright St. John's Wort). 

 Stem erect, round, smooth ; leaves heart-shaped, embrac- 

 ing the stem, smooth ; sepals obtuse, fringed with sessile 

 glands ; petals fringed with glands. Heaths and woods, 

 common. A slender plant, with scanty foliage and 

 golden-yellow flowers, which when in bud are stained 

 externally with red. Fl. July, August. Perennial. 



10. H. elodes (March St. John's Wort). Stem creep- 

 ing ; branches erect ; leaves roundish, and, like the stems, 

 densely clothed with shaggy down. Spongy bogs, com- 

 mon. Flowers few, pale jellow," remaining open but a 

 short time. The plant may be detected at some dis- 

 tance by the hoariness of its foliage, and by the strong 

 and far from pleasant resinous odour which it emits, 

 especially in hot weather. Fl. July, August. Perennial. 



* The other British species, of St. John's Wort are, 

 H. maculdtum (Spotted St. John's Wort), which grows 

 in wet places, and may be distinguished from H. quad- 

 rdngulum by its reflexed toothed sepals, and by purple 

 streaks and dots on the petals beneath : H. linariifolium 

 (Narrow-leaved St. John's Wort), which is nearly allied 

 to H. humifusum, but has erect stems, and about 30 

 stamens, found on the sea-coast of Devon and Cornwall, 

 very rare ; and H. barbatum (Bearded St. John's Wort),
