flowered rose, forms of which may have sint^le or double flowers, 

 in either white or yeUow, similar in shape to those of flowering 

 cherries. This rose, under favorable conditions, is cajxible of 

 phenomenal growth. Deslongchamps tells of a si:)ecimen grow- 

 ing in the Jardin de la Marine, at Toulon, which, in 1842, had a 

 trunk two feet foiu' inches in circumference, its branches covering 

 a wall seventy-liN'e f(_^et long and eighteen feet high. The 

 Banksian Rose is represented in the conservatories of the Brook- 

 lyn Botanic Garden, lout although we have had it many years, 

 never a flower has it produced. 



Bourbon Roses 



Rosa chinensis X Rosa damascena. var. It is supposed that 

 from this cross there were derived the Bourbon roses, so-called 

 because they originated in the Isle of Bourbon (Reunion),' where 

 they were discovered by M. F^reon, Directeur du jarflin Bota- 

 nique de I'lsle de la Reunion, in 1817. (Rehder gives the origin 

 of the Bourbon Roses as R. chinensis X tallica.) 



The following acc'ount of the origin of the Bourb(Mi Rose is 

 given by M. Breon as (juoted by S. B. Parsons in "The R.()se":^ 



"At the Isle of Bourbon, the inhabitants generally inclose their 

 land with hedges made of two rows of roses; one row of the 

 common China Rose, the other of the Red Four Seasons. M. 

 Perichon, a planter in the island, found in one of these hedges 

 a young plant, diflering very much from the others in its shoots 

 and foliage. This he transplanted into his garden. It flowcMcd 

 the following year, and proved to be of a new race, and wry 

 difterent from the above two roses, which at that time were the 

 only varieties known in the island." 



The rose known as h^our Seasons was derived from R. dama- 

 scena. 



Some of the Bourbon roses are \'igorous enough to be used as 



pillar roses or for training on a trellis. An example is Zephirine 



Drouhin. 



Boursaidt Roses

 species, probably by cossing with R. chinensis, the Boursault
