Phtheirospermum japonicum / Koshiogama コシオガマ

Phtheirospermum japonicum is a semi-parasitic annual, 30-60cm tall, with dense, tender glandular hairs and sticky to the touch. Leaves alternate, 3-5cm long, 2-3.5cm wide, triangular-ovate, and split pinnately. Axils on the upper branches produce single, about 2cm long, light red-purple flowers. Corollas are plump-tubular-lip-shaped; upper lips bend backward, the tips shallowly cut in two, while the lower lips significantly expand sideways and cleft shallowly in three. Stamens are four in number, and two are somewhat longer. Calyxes are bell-shaped and split in five, with margins serrated and relatively dense glandular hairs. Bloom time: September-October.
