The Aristolochia which forms the subject of our plate was 
first collected by von Martius in the course of his travels in 
the Brazilian provinces of Bahia and Minas Geraes between 
1817 and 1820, and was described by its discoverer. The 
original description is accompanied by a figure by Zuccarini 
in which the cream-coloured reticulations on the perianth 
are not shown. ‘The species from Pernambuco which 
was figured at t. 4221 of this work as A. gigantea is 
quite distinct from the original A. gigantea, and was sub- 
sequently described as A. grandiflora, var. Hookeri, by 
Duchartre; it is readily distinguished from our present 
plant by the apex of the perianth limb being long-caudate 
and not obtuse. The plant from which the material for 
our illustration has been derived is one that was presented 
to the collection at Kew in 1910 by Sir Frank Crisp; at 
the time of its receipt it was believed to be A. clypeata, 
Linden & André, a closely allied species from New Grenada, 
Marcu, 1914, : ;
