BOTANICAL CLASSIFICATION. 13 



ers are also without bracts, except in some species not 

 mentioned here. These, having connivent permanent se- 

 pals, cannot be confounded witli the preceding division ; 

 nor, on account of their disk, with the following. There 

 is no instance of stipular prickles in the present tribe. 

 The sepals are entire, or nearly so. 



R. sulphlirea. Ait. — The Sulphuk-colored Rose. — 

 The Double Yellow Rose. Syyionyms, R. hemispherica, 

 ITerm. R. glaucophylla, Ehrh. Rosa lutea flore })leno, Rai, 

 Hist. R. lutea, Brot. Stipules linear, divaricate, dilated 

 at the apex. Leaflets glaucous, flattish. Tube hemispheri- 

 cal. Stem prickles unequal, scattered. Flowers large, of 

 a fine transparent yellow, always double. Xative of the 

 Levant ; growing to the height of from four feet to ten 

 feet, and flowering in July. 



This sort does not flower freely, except in open, airy 

 situations and trained against a wall, exposed to the 

 north or east, rather than to the south. Its flower buds 

 are apt to burst on one side before they expand, and, con- 

 sequently, to become deformed; to prevent this, the 

 blossom buds should be thinned, and care taken that they 

 have abundance of light and air. Watering it freely in 

 the flowering season is also found advantageous, and the 

 shoots in general ought not to be shortened. This beau- 

 tiful species is said to flower freely, if grafted on the musk 

 cluster at eight feet or ten feet from the ground ; or it 

 will do well on tlie China rose. It is grown in great 

 abundance in Italy, where its flowers produce a magnifi- 

 cent eff*ect, from their large size, doubleness, and brilliant 

 yellow color. It is one of the oldest inhabitants of our 

 gardens, though the exact year of its introduction is un- 

 known. " Ludovico Berthema tells us, in 1503, that he 

 saw great quantities of yellow roses at Calicut, whence it 

 appears probable that both the single and double-flow- 

 ered varieties were brought into Europe by the Turks ; as 

 Parkinson tells us, in a work which he dedicated to Hen- 

 rietta, the queen of our unfortunate Charles I., that the
