74 THE AZALEAS OF THE OLD WORLD 



in western gardens, having been sent by Joseph Poole from China to Samuel Brookes, 

 nurseryman, Ball's Pond, Newington Green, England, in 1819. The flower is rose- 

 purple, fragrant, quite, or only partially double, and with or without green rudi- 

 mentary leaves showing in the centre of the flower. Hovey tells us that this plant 

 was cultivated by Mrs. Hibbert and exhibited before the Pennsylvania Horticul- 

 tural Society on February 19, 1839.

This is a monstrous garden form cultivated in Japan but rather rare. The leaves 

 are narrow, strap-shaped, and the corolla is divided into narrow, ligulate segments. 

 An analogous plant is jR. i/ndicum f . polypetalum Wils. Maximowicz says it was in- 

 troduced into the gardens of Tokyo from the alpine regions of Sendai in north- 

 ern Japan. This is a mistake. It is unknown in a wild state and was first known 

 from the neighborhood of Nagasaki in Kyushu the southern island of Japan. Its 

 Japanese name is " Seigai-tsutsuji." It was introduced into England by Messers 

 Standish with whom it flowered in November, 1867, and again in February, 1869. 

 It is well figured in the Botanical Magazine. From England it appears to have 

 been sent to this country for it flowered in the garden of Mr. H. H. Hunnewell, 

 Wellesley, Mass., in 1876. According to Bean it is quite hardy at Kew. It is not 

 hardy in the Arnold Arboretum and I do not know whether it is now cultivated 

 in America.
