Melampyrum roseum var. roseum / Tsushimamamakona ツシマママコナ

Melampyrum roseum var. roseum closely resembles another variety, Melampyrum roseum var. japonicum. The inflorescence extends itself more, 10-20cm long; flowers are sparser, hairs are fewer on the floral axis, and fewer serrations on the bracts - all those descriptions are abstract. I apply only to individuals that have much fewer serrations. Bloom time: August-October.
