 Thunb. fl. jap. p. 124. ex Roem. et Schultes, or Viburnum to- 

 mentosum, Thunb. ex Curt, but the descriptions of neither of 

 these two plants agree with the present. The plant is called 

 Temerihana, i. e. globe-flower, by the Japanese ; and Fun-Dan 

 Kma by the Chinese. Flowers varying from rose-coloured to 

 blue according to the soil in which the plant is grown ; the 

 sterile flowers are nearly always 4-cleft ; but the fertile 

 flowers are small and perfect. The plant is much valued on 

 account of the great profusion of its very elegant flowers, which 

 are monstrous, in the same manner as the Snow-hall Guilder 

 Rose. It was introduced by Sir Joseph Banks in 1790. The 

 plant was first called Peaiitia by Commerson, in honour of Dae 

 Hortense Lapeaute.

 gated leaves, called Fiuri- Azisai by the Chinese.

 ja, i. e. sweet tea ; and Do-Sioo-San by the Chinese. Accord- 

 ing to the Japanese, there is a variety with bitter leaves, which 

 they call Kakossoo.
