THE HORSE-CHESTNUT, ^sailus and Pavia. 
Under this head maybe classed the species known as European 
horse-chestnuts, the American varieties known as buckeyes, and 
the smooth-fruited horse-chestnuts, the latter being botanically des- 
ignated as Pavias ; though the differences between them and the 
European horse-chestnuts do not seem to warrant so distinctive 
a separation. We shall treat them all as varieties of horse-chestnuts.

The species was first brought 
to England in 1550 ; but it was 
Fig. 107.
