Oxyacantha, which has commonly separate styles, and is 
variable in Cu#NomMELES and AMELaNcHIER Botryapium. 
The Willow-leaved Pear was introduced by Chevalier 
Pallas in 1780; and does well with us in the open ground. 
‘It has been observed wild in Persia, in Iberia, in the vi- 
cinity of Tifflis, on the plains of Mount Caucasus, in Siberia, 
on the banks of the Terek, and in the Levant. We have no 
figure of it in any of our popular publications. 
The fruit shown in our plate is of the full size; though it 
finally turns brown. ‘The flesh is thin, granulated, and of a 
stony hardness. The tree is bushy and grows to the height 
of from six to twelve feet, with a stem that seldom exceeds 
two inches in diameter, the wood of which is exceedingly 
hard, white, and close-grained, being said to polish nearly 
as well as ivory. The flowers grow many together in a 
corymb; but scarcely ever more than two, and generally 
only one, in each corymb, produce fruit even on the native 
tree. 
The author of the Flora Taurico-caucasica distinguishes 
the species of this article from P. elwagrifolia of the same 
regions, by the narrower slightly undulated leaves with a 
thinner silvery fur, and by the same being sometimes glan- 
dularly, though faintly, crenate, as well as by a style longer 
than the stamens. 
The following is our english version of Mr. Lindley’s 
restricted character of the genus: “ Calyx 5-toothed. Petals 
nearly round. Fruit (Pome) closed at the top, 5-celled, 
with a cartilaginous shell or cell-case (putamen). Cells 2- 
seeded. Seedcoat cartilaginous.” 
The genus is arranged under three divisions, and is 
composed at present of 24 certain and 3 doubtful species, 
to which, Mr. Lindley says, several undescribed ones from 
India, in the Banksian and Lambertian Herbariums, are to 
be added, as well as one from Mexico in Mr. Lambert's 
possession. 
Pyrus, under this limitation, does not appear to have 
any recorded representative of the type, either in South 
America or in South Africa.
