A curious and showy species of Aristolochia, discovered by 
M. Wallis on the Upper Amazons, whilst collecting for Mr. — 
Linden of Brussels in 1866, and named by M. André in 
honour of M. Duchartre, the eminent Paris botanist, and 
author of the “ Monograph of Aristolochia” in De Candolle’s 
“ Prodromus.” As a species it is allied to the 4. /euconeura 
(Tab. Nost. 5420), but has much handsomer flowers, which 
are abundantly produced during a good part of the year. 
The specimen here figured flowered in the Royal Gardens 
in January, 1868, and was received from Mr. Linden. : 
Descr. Stem climbing, as thick as the little finger, brown, 
grooved, corky. Branches annual, slender, glaucous. Leaves 
long petioled, four to five inches in diameter, coriaceous, 
shining, broadly reniform-cordate, suddenly acuminate, dark- 
green and glaucous above, pale below, palmately five to seven-
