tv 88. H. sulphu v reum WUld. The sulphur-colour-flowered Helianthemum, 



or Sun Rose. 



Identification. Willd. Enum. Suppl., 39. ; Swt. Cist., t. 37. ; Don's Mill , i. p. 314. 

 Engraving. Swt. Cist, t. 37. 



Spec. Char., $c. Stems branched, procumbent. Leaves lanceolate, flat ; upper 

 surface green, under surface paler, but beset with stellate pubescence on 

 both surfaces. Racemes terminal, few-flowered. (Don's Mill., i. p. 314.) 

 A native of Spain, and cultivated in British gardens in 1795. A very dis- 

 tinct variety, when in flower, during June and July. It is tolerably hardy, 

 but requires a little protection during very severe frosts. Plants were in the 

 Fulham Nursery in 1826. 



tv 89. H. strami'neum Swt. The straw -colour-flowered Helianthemum, 



or Sun Rose. 



Identification. Swt. Cist, t 93. ; Don's Mill., 1. p. 314. 

 Engraving. Swt. Cist., t 93. 



Spec. Char., Sf-c. Stems branched, elongated, procumbent, tomentosely 

 pubescent at the apex. Leaves flat, or with the margins scarcely revolute ; 

 green above and pilose, hoary-tomentose beneath; lower ones roundish ovate, 

 obtuse; upper ones oblong-lanceolate, acutish. Stipules lanceolate, acute, 

 ciliated, twice the length of the petioles. Racemes many-flowered. Calyx 

 striated, smoothish. Petals obovate, spreading, distinct. (Don's Mill., i. p. 

 314.) Found in gardens, and, probably, a hybrid. Its straw-coloured 

 flowers are produced from May to August. Plants were in the Clapton 

 Nursery in 1829. 



Variety. 



fu H. s. 2 multiplex (Swt. Cist., t. 94.) has double straw-coloured 

 flowers, with the petals orange-coloured at the base. It is a very 

 beautiful variety, tolerably hardy. Plants of it were in the Hammer- 

 smith Nursery in 1829. 



a. 90. H. diversifo v lium Swt. The various-leaved Helianthemum, or 



Sun Rose. 



Identification. Swt Cist, C. 95.; Don's Mill., 1. p. 314. 

 Engraving. Swt. Cist, t. 95. 



Variety. 



«. H.d. 2 multip lex.— Flowers large, double, and of deep purplish red, mixed with lighter- 

 coloured ones. 



Spec. Char., Sf-c. Stem sufFruticose, ascending, branched. Branches rather 

 tomentose, erectly ascending. Leaves stalked, green, hairy above, hoary- 

 tomentose beneath ; lower ones oval or oblong, obtuse, flat ; upper ones 

 linear-lanceolate, ciliated, three to four times longer than the petiole. 

 Sepals pilose. Petals crenulated, distinct. (Don's Mill., i. p. 314.) It is 

 not known of what country it is a native; but it is, or has been, cultivated 

 in England, as Sweet's drawing was taken from a plant in the Hammersmith 

 Nursery in 1829. It is nearly allied to H. jooliifolium, and has a very 

 brilliant appearance from May to June, from the dark rich red of its flowers, 

 each of the petals of which has a deep copper-coloured mark at its base. 

 The plant is a very desirable one for rockwork. When grown in pots, it 

 requires a light sandy soil. 



!U 91. H. eriose'palon Swt. The woolly-sepaled Helianthemum, or Sun 



Rose. 



Identification. Swt. Cist, t 76. ; Don's Mill., 1. p. 314. 

 Engraving. Swt. Cist, t 76. 



Spec. Char., fyc. Stems branched, procumbent, rather tomentose, hoary at 

 the apex. Leaves lanceolate, acute, with somewhat revolute margins, green 

 on both surfaces, and beset with starry hairs. Stipules linear, acute, ciliate, 

 twice as long as the footstalks of the leaves. Racemes terminal, many- 

 flowered. Calyxes clothed with woolly hairs. Petals obovate, crenulated,
