Euphorhiacew.'] 
MEXICO. 
309 
Of this curious genus there is one,* perhaps two species, in the Mexican collection of Andrieux, from which 
the excellent Endlicher has derived his character of the Genus Antigonon, and which he has rightly placed 
next to Brunnichia, in the order Polygone^, Trib. III. “ Polygonece spuricE.” Indeed all the three are so 
closely allied, that they may possibly constitute but one species, the only striking difference I can find being 
that Andrieux’s specimens (which are not very perfect) have singularly dilated footstalks to the leaves. In 
the n. 1 17 of Andrieux, there is, on each side of the stem, at the base of the petiole, a rather large transverse 
stipule ; but in the other specimen, or species, the base of the petiole is continued merely in the^form of a 
slightly elevated line all round the stem, as in our plant. Perhaps the stipules themselves have been very 
early deciduous. In our specimen, again, there is a slight difference in the flowers, which have three outer 
leaves of the perianth considerably larger than the rest ; and there are three inner ones, of which one is gene- 
rally abortive. Our fruit, though fully formed in appearance, contains only an imperfect seed.

Lanrin. p. 302. 
The flowers seem to be all female, and we are doubtful to what genus of Laurinece of Nees von Esenbeck 
this should be referred. That author, indeed, places it in Nectandra,\i\A. he had not seen the flowers. We 
are rather disposed to refer it to his section OaEODAPHNEiE, and probably it may come under Ocotea, as 
now circumscribed by Nees. 
There are specimens of two other Laurinece in the collection, one belonging to the Cinnamomum tribe. 
Ord. LXXIIL ARISTOLOCHIE^. Juss. 
1. Aristolochia Taliscana ; volubilis glabra, foliis petiolatis cordato-rotundatis obtu- 
sissimis basi sinu profundo lateque bilobis lobis rotundatis subtus pallidioribus, pedunculo 
axillari solitario unifloro folium superante, perianthii tubo breviusculo labium recurvum 
late ovatum intus filamentoso-papillosum tequante. 
Hab. Talisco. — Apparently a distinct species from any hitherto described. The leaves about two inches 
long, and the same in breadth. The lip of the flower is nearly an inch long, about equal in length with the 
tube, suddenly bent back, clothed on the upper side with fleshy club-shaped appendages. 
Ord. LXXIV. EUPHORBIACE^. Juss. 
1. Jatropha Curcas? L Hab. Talisco. 
1. Hermesia ? Mexicana ; pubescenti-scabra, ramis teretibus, foliis ovato-oblongis 
acutis serratis, spicis masculis solitariis axillaribus, perianthio masc. 3-partito, stamini- 
bus 8 ? 
*A. platypus ; petiolo supeme dilatato alato. “ Anredera ?” Andrieux Plant. Mexic. exsicc. n. 117 — No. 116 also, 
of the same collection, is an Antigonon, with larger flowers and leaves, and the petiole narrower, though distinctly 
winged ; but it may be merely a variety. Both inhabit Tlacolola of Oaxaca.
