The reference is:
Arisaema biradiatifoliatum Kitamura in Acta Phytotax. Geobot. 10: 187 (1941).
a name given to the Taiwanese form of A. consanguineum. It means "with two
radiate leaves"; no wonder as A. consanguineum in Taiwan usually has two
leaves when mature, i.e. when a female flowering specimen.
One of the leaflets in all SINARISAEMA can be considered "central" and is
often slightly upwards, while others correspond to the "laterals" as in a
section such as TORTUOSA.
Best wishes.
