ARISTOLOCHIA HYPERBOREA. 
duced in this position, as their exterior surface is almost destitute of the rich stains 
which characterise the interior. Its habit may he seen from the subjoined woodcut. 
Although the species of Aristolochia are 
generally notorious for the offensive odour of 
their flowers, this property is scarcely percep- 
tible in our present subject. 
We have sought in vain for any informa- 
tion respecting the native country and intro- 
duction to Britain of this species. Mr. Knight, 
of the King's Road nursery, Chelsea, has 
grown it for several years in his stove, and it flowered abundantly in 1838. 
That gentleman presumes that it was obtained from one of the northern 
districts of India, and there is great probability of this proving correct. So far as 
we have been able to ascertain, it has never before been published, and we have 
reason to believe it a new species. 
It requires the usual treatment of climbing stove plants. A shaded situation, 
such as is afforded in an orchidaceous house, would be the most suitable ; and it 
should be trained to the rafters of the roof in preference to a wall, as the flowers 
are displayed more advantageously in the former position. A rich loamy soil, 
and abundant syringing, are the principal points to be attended to in its further 
management. Propagation may be effected by cuttings. 
In the exotic nursery of Mr. Knight, Chelsea, this species blossomed in the 
month of May, 1838, and that gentleman kindly permitted our artist to execute 
a drawing at that period. We have since been favoured with a beautiful figure 
of the same plant from Messrs. Ronalds, of Brentford. 
The derivation of the generic name will be found in vol. iii. p. 2.
