Piate LXXXVIL 
ARISTOLOCHIA patuipa, Willd. 
Natural Order ARISTOLOCHIACE®. 
Gen. Cuar.—See description of Plate LXIV. Part II. 
Spec. Cuar.—flowers variable in colour, pale yellowish-green, often 
with a dark purple-brown blotch in the throat, the lip more or less covered 
with purplish reticulate markings inside; peduncles very short, about one- 
sixth of an inch long. Perianth tube clavate, slightly longer or shorter 
than the ovate or oblong-ovate, acute or obtuse lip. Stigmatic lobes at 
first erect, conical, distinct, afterwards confluent (when a kind of deli- 
quescence sets in). Leaves glabrous, broadly cordate, slightly emarginate, 
basal lobes usually approximate ; petiole varying from 1} to 3 inch or more 
long. Rootstock subglobose.

Hasitat.—Gathered by my father on the eastern end of Mont Cheiron 
(arrondissement de Grasse, Alpes Maritimes), on May 6th, 1870. 
RemarKs.—Aristolochia pallida, Willd., appears to have no character 
which absolutely distinguishes it from longa, Auct.* except the roundish 
shape of its rootstock, as opposed to the fusiform or subcylindrical root- 
stock of the latter. The following are the distinctive peculiarities of leaves, 
flowers, and stems assigned by M. Duchartre,} who says that A. pallida is 
distinguished from, “ though most closely allied to, A. longa, by its paler 
colour, more delicate habit, subglobose tuber, usually unbranched stem, 
leaves shorter in proportion to breadth, having longer petioles, the colour 
of the flower, the shorter and subclavate tube, and finally by the longer 
obtuse lip,” but these characters break down one by one when applied to 
a large series of specimens. 
However, the rootstocks appear to be markedly distinct, and it would 
appear that in A. longa at least this feature is accurately reproduced by 
seed, for I have received, thanks to the kindness of Dr. D. Moore of Glas- 
nevin, five three-year-old seedling plants of A. longa, in all of which the 
rootstocks were about as long as my hand, fusiform, and as thick as my 
little finger, tapering below to the size of whipcord. 
A. pallida is well distinguished from A. rotunda, L., by its distinctly 
stalked leaves, and if treated as a variety it should be placed, as it is pro- 
visionally in M. Boissier’s herbarium,t under A. longa.

¢ The label is thus given, “ A. longa, L., var. radice globosa.”
