 Varieties. De Candolle distinguishes three forms of this species: H. F. mdjor, H. F. minor, and 



H. F. virg&ta. 



Spec. Char.y $c. Stem branched, twisted, rather diffuse, 

 erectish ; lower branches procumbent. Leaves al- 

 ternate, linear, with pilose, roughish, rather involute 

 margins ; lower leaves short, crowded, upper ones 

 scattered and longer. Peduncles solitary, 1-flow- 

 ered, rarely rameal, usually almost opposite the 

 leaves, or terminal, longer than the leaves. Capsules 

 open, naked. (Don's Mill., i. p. 307.) A shrub 

 1 ft. high, a native of the south of France, of Swit- 

 zerland, Italy, Spain, and Portugal ; and cultivated 

 in England since the year 1752. It flowers in June 

 and July, and is distinguished by its heath-like 

 leaves and ovate petals. It is a very desirable 

 species for growing in pots, or for the south side of 

 rockwork. Sweet says it is often confused with 

 H. procumbens, but is readily distinguished when both are growing toge- 

 ther. The true H. Fumana was in the Chelsea Botanic Garden in 1825.

 native of the south of France, Italy, and Tauria; and cultivated in the Chelsea 

 Botanic Garden in 1825, where it produced its small yellow flowers from 

 June to August. Uses and culture as in the preceding species.

 seldom exceeding half a foot in height ; though it acquires double that height 

 in British gardens, where it produces its yellow flowers in June and July. 

 It was introduced before 1 826, as plants of it flowered in that year in the 

 Chelsea Botanic Garden.
