these two plants agree with the present. The plant is called 
Temerihana, i. e. globe-flower, by the Japanese; and Fun-Dan 
Kwa 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-ball Guilder 
Rose. It was introduced by Sir Joseph Banks in 1790. The 
plant was first called Peaùtia by Commerson, in honour of Dæ 
Hortense Lapeaute.
