Distribution and habitat
Rafflesia balatociana is known currently only from the
south-western Kalinga Province, in the tropical upper montane forests of
the Cordillera Central, Luzon Island (Figs. 4A‒D ). It occurs in
mossy forests at an elevation of ca.1750–1800 m near Mt. Alimungao. The
host Tetrastigma species (refer to Fig. 4L ), could not
be identified with certainty (taxonomic limits in the genus are
unresolved), and due to restrictions in accessibility, specimens could
not be collected or deposited.
