 ing to the height of from 4 ft. to 6 ft., and flowering in May and June. It forms a very 

 distinct variety, or probable species, and on that account, is well deserving a place in 

 botanical collections.

 the double yellow Rose. 



Spec. Char., fyc. Stipules linear, divaricate, dilated at the apex. Leaflets 

 glaucous, flattish. Tube hemispherical. Stem prickles unequal, 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 1 season is also 

 found advantageous, and the shoots in general ought not to be shortened. This 

 beautiful species is said to flower freely, if grafted on the rnusk 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 effect, 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 double-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, from Constan- 

 tinople, which (as we hear) 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.' "
