 Nursery, Chelsea, in 18-^8. It la nearly related to II. suii)iHireuni, but

I ow/tf. ^ ^ mjUiipU'i. (Swt. Cist, 86.) — A very pretty double variety : It is well suited to rock- 

 ' work, on which it grows vif!orously,'and produces large flowers. It is quite hardy, and 

 continues in bloom the whole summer. 



Spec. Char., <.^c. Stem suffruticose, rather procumbent, somewhat tomcntose. 

 Leaves ovate-lanceolate, tomentose on the under surface, green above, 

 hairy. Stipules lanceolate-linear, ciliated. Pedicels and calyxes pilosely 

 hairy. (Don's Mill., i. p. 314.) A native of the south of Europe, and very 

 nearly allied to H. vulgare. The petals lu-e rose-coloured, and imbricate at 

 the base. It flowers in June and Jidy, and was introduced in 18.1.5. It is 

 a very pretty plant, from the delicate colour of its flowers ; and it is very 

 suitable for rockwork, as it will continue in bloom for several months. It 

 requires protection during frosts. It was cultivated in the Fulhani Nui'scry 

 in 1827.

 from it in having white flowers. The whole plant is said to smell like .Bryonia. It produces its 

 flowers f^om May to July, and was in cultivation in 1800.

 Varieties. 



U H. h. 1 croedtum (Swt. Cixt., t. 92.) has flowers safl^ron-coloured, with 

 more or less, of a ferrugineous tint, and may represent the species. 

 Plants of it were in the'Clapton Nursery in 1828. 

 f^ II. h. 2 ciipreum (Swt. Cist., t. 58.) has flowers of a reddish copper- 

 colour. Plants of it were in the Fulham Nursery in 1827. 

 1. //. h. 3 miltiplex (Swt. Cist., t. 72., and our 

 Ji<f. 75.) has double flowers, of a reddish 

 copper-colour. Plants of this variety were 

 in the Fulham Nursery in 1828. 

 Description, Src. All the three forms of this species 

 are splendid plants ; they are hardy, of luxuriant 

 growth, flowering freely, and of the easiest culture, ' 

 either in pots or on banks of light sandy soil, covered 

 with flints or stones. Tiie flowers of the copper- 

 coloured varietv, and also the leaves, arc larger than 

 those of the two other kinds. The double-flowered 

 variety appears to be of a more upright habit of 

 growth, and not quite so robust as the others. Sweet 

 says that he is " acquainted with two other very 

 distinct varieties; one witii flower.s of a lighter 

 colour, and the other having double flowers."
