with a short white tomentum and a few hairs inter- 

 mixed, nodding before the flowers expand, erect when 

 in bloom, afterwards reflexed . Calyx of 5 sepals ; the 

 two outer ones small, oblong or ovate, obtuse, very hairy 

 and fringed ; 3 inner ones ovately lanceolate, acute, 

 concave inwards, membranaceous, strongly 4-nerved, 

 the nerves very hairy. Petals 5, variable in breadth, 

 obovate or broadly wedge-shaped, or sometimes round- 

 ed at the points, the margins generally a little crenate, 

 generally more or less imbricate, but sometimes distinct, 

 of a bright yellow ; in some plants having a bright 

 orange-coloured lunulate spot near the base, in others 

 of a plain yellow. Stamens about 70 ; filaments smooth, 

 scarcely as long as the style. Gennen downy. Style 

 smooth, nearly straight, or a little bent towards the 

 point. Stigma capitate, papillose. 



Our drawing of this species was taken from plants 

 growing wild in Croome Hurst Wood, near Croydon, 

 in which neighbourhood all the banks and sides of the 

 hedges are covered with it, the soil being of a chalky 

 nature, in which it delights ; in the same wood we, in 

 company with Mr. Charlwood, discovered a large patch 

 of H. surrejanum, most probably the very one from 

 which the late Mr. Dickson originally procured his 

 plant, which is somewhat altered by culture, as may be 

 seen by comparison of our figure of that species, and 

 the branch given at the bottom of this plate ; a plant of 

 it which we planted in our garden has already much 

 broader and flatter leaves, more like Mr. Dickson's 

 plant ; the present is certainly the plant of Dillenius's 

 Hortus Elthamensis, as it agrees entirely with his figure 

 and description : both species may be grown in rock- 

 work, and if some chalk be added to the soil, so much 

 the better; they are readily propagated by cuttings, 

 planted under hand-glasses in Autumn. 



1. The commonest yellow variety. 2. A scarcer variety, with an orange co- 

 loured spot at the base of each petal. 3. Helianthemum surrejanum, from a spe- 

 cimen gathered growing wild in Croome Hurst Wood, Surry, differs from the 

 cultivated plant already figured, in being weaker, with fewer flowered racemes, 

 and the leaves being canescent underneath.
