362 JACK’S MALAYAN PLANTS. 
ARISTOLOCHIA HASTATA. JW. J. 
Foliis hastato-trilobis glabris, racemis axillaribus, perian- 
thio basi inflato, lamina erecta ellipticà marginibus revolutis. 
Found at Nattal on the west coast of Sumatra. 
Suffrutescent; branches long,spreading over the neighbour- 
ing shrubs, but not twining, angulate, jointed, smooth. Leaves 
alternate, petiolate, from six to ten inches long; hastately 
three-lobed, middle lobe elongated and terminating in a blunt 
acumen, very entire, very smooth, five-nerved, and strongly 
veined. Petioles two inches long, thick, round, channelled 
above. Racemes axillary, longer than the petioles. Flowers 
alternate, pedicellate, somewhat distichous; rachis flexuose. 
Perianth superior, purplish-red, smooth without, inflated at 
the base into an ovate six-angled ventricle, from which rises 
an ascending infundibuliform curved tube with revolute 
margins ; lamina erect, elliptic, revolute at the sides, tomen- 
tose on the inner surface, as is also the inside of the tube. 
Style short, thick. Stigma orbicular, peltate, divided on 
the summit into six conical erect lobes. Anthers sessile, 
regularly arranged in a circle below the stigma, six in number, 
each consisting of two lobes, which are 2-celled and deeply 
furrowed along the middle. (As these are not arranged by 
pairs, might they not with equal propriety be considered as 
twelve distinct two-celled anthers?) Ovary oblong, obtusely 
six-angled, six-celled, many-seeded. 
Ogs. This is a large and very beautiful species of Aristo- 
lochia, remarkable for the size and form of its flowers. The 
ventricle at the base is large, and the narrow urn-like tube 
rises upwards with a very graceful curve. In this species 
the anthers might properly be considered as twelve in 
number, each two-celled; as they are all arranged at equal 
distances round the stigma, and it seems questionable whether 
the Genus itself ought not to be referred to Dodecandria in 
place of Hexandria. The arrangement of the anthers by 
pairs in the other species does not appear to necessitate the 
supposition of a deviation from the usual structure in ascribing
