the flowers varying slightly in color from 

 seed. Seed treated as horsechestnuts, make 

 fine plants. The flowers appear later than 

 the horsechestnut, and the leaves fall earlier. 

 The P. macrostachya is a strong growing 

 and highly ornamental shrub, of which there 

 are several varieties. 



PAULOWNIA, Siebold. Nat. Ord. Scrophu- 

 lariaceae. Didynamia, Angiospermia, Linn. 

 Calyx 5-cleft; segments equal, coriaceous, 

 covered with a rusty down. Corolla 2 -lipped, 

 imbricated in its aestivation ; the two upper 

 lobes external. Fruit ovate, with a sharp 

 point. 



P. IMPERIALIS, Siebold. The only known 

 species is a native of Japan, and thrives ad 

 mirably in this climate. It is as rapid a 

 grower as the ailanthus, the wood and trunk 

 of the tree also resembling it. The leaves 

 are rather coarse, looking like large melon 

 leaves; but the beauty of the large clusters 

 of sky-blue flowers which appear in June, 

 covers all blemishes. It will thrive in any 

 good loam, and may be readily propagated 

 by cuttings of the roots.
