arrive at any satisfactory conclusion respecting their consti- 
tuent parts, first to acquire as perfect a knowledge as pos- 
sible of the species, as found in a wild state, without any 
reference to the productions of the gardens; and afterwards, 
to reduce the garden varieties to those wild stocks from 
which they may reasonably be supposed to have arisen. In 
their domesticated state, plants may be so altered by con- 
tinual reproduction from seed formed under unnatural or 
artificial circumstances, as in course of time to depart from 
their first forms, and to become nearly incapable of being 
recognized. They ought not, however, on that account, to 
take the same rank as species which have been produced by 
the hand of nature; but rather to be set apart as anomalous, 
and frequently perishable individuals, with which science 
has no concern, except as far as they may indirectly explain 
the obscure operations of vegetation. 
Our drawing was made in the Garden of the Horticul- 
tural Society, in June last; to which collection it was pre- 
sented by M. Pronville, of Versailles. 
An erect, branching shrub, about four feet high. 
Branches dark green, glaucous, sometimes unarmed, some- 
times covered with close, unequal, short, falcate prickles 
and setae. Leaves close, rigid, nearly evergreen; leaflets 
ovate-oblong, acuminate, simply serrate, above rugose, 
shining, smooth, beneath glaucous, smoothish ; petioles and 
primary nerves pubescent, and armed with scattered hooked 
prickles ; stipules linear, entire, adnate, subulate at end. 
Cymes about 5-flowered, stalked; their stalk and the pe- 
dicels covered with setze. Bracts ovate, acuminate, reflexed, 
ciliated with glands. Flowers expanding, large, white, 
tinged with pink. Petals obcordate, 5 or 7. Tube of the 
calyx elliptical, setose ; sepals compound, glandular. Disk 
conspicuous. Styles united in a column. Fruit obovate, 
smooth, orange-coloured. Sepals deciduous.
