Spec. Char., (^c. Stipules linear, divaricate, dilated at the apex. Leaflets 

 glaucous, flattish. Tube hemispherical. Stem prickles uneqital, scattered. Flow- 

 ers large, of a fine transparent yellow, always double. Native of the Levant ; 

 growing to the height of from 4 ft. to 10 ft., and flowering in July. This sort 

 does not flower freely, except in open airy situations ; and. if 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 consequently 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 

 beautiful species is said to flower treely, if grafted on the musk cluster at 8 ft. or 

 10 ft. from the ground; or it will do well on the China rose. It is grown in great 

 abundance in Italy, where its flowers produce a magnificent efiect, 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 unknown. "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 donble-flowered varieties 

 were brought into Europe by the Turks; as Parkinson tells us, in a work which 

 he dedicated to Henrietta, the queen of our unfortunate Charles 1., that the double 

 yellow rose 'was first procured to be brought to England, by Master Nicholas 

 Lete, a worthy merchant of London, and a great lover of flowers, tiom Constan- 

 tinople, which (as we liear) was first brought thither from Syria, but perished 

 quickly both with him, and with all other to whom he imparted it; yet afterward 

 it was .sent to Master John de Frangueville, a merchant of London, and a great 

 lover of all rose plants, as well as flowers, from which is sprung the greatest store 

 that is now flourishing in this kingdom.'"
