drupe inferior, from two to five seeded, 
Mesp. Oxyacantha, Hawthorn, White-thorn, or May ; 
spinous, with obtuse nearly three-cleft, smooth serrated 
leaves ; flower with two pistils. This plant, of which 
varieties are produced by culture, is well known for its 
important application in making living hedges, for 
which it is admirably fitted by the stiffness of its 
branches, the sharpness of its thorns, and hardy na- 
ture. 
Mesp. Germanica, the Common Medlar ; is without 
spines, has downy leaves, and flowers with five styles ; 
is not uncommon in gardens and shrubberies. 
Pyrus. Gen. char. — Cal. five-cleft ; petals five ; 
pome or apple, inferior, from two to five celled, seeds 
two. 
Pyr. Communis, Pear-Tree ; with simple serrated 
leaves, and corymbose peduncles ; in woods and 
hedges ; but the cultivated varieties are almost end- 
less. 
Pyr. Malus , Crab-Tree, or Apple-Tree ; with sim- 
ple serrated leaves, and simple sessile umbels ; native 
of woods and hedges, and the parent of all the culti- 
vated varieties of the apple. 
Pyr. Aucuparia , Mountain Ash, Quicken or Roan- 
Tree ; with smooth pinnated leaves, leaflets serrated ; 
common in woods and hedges, and deservedly admired 
for its white flowers in the early summer, and scarlet 
berries in the autumn.
