What is Isodon longitubus

Chelonopsis longipes (scientific name: Chelonopsis longipes) is a perennial herb in the family Lamiaceae and is endemic to Japan. It grows wild in Honshu (the Kanto region and westwards) to Kyushu in lowlands and mountainous areas along valleys and forest margins. It produces several stems from rhizomes. The stems are erect and slanting, and the herb grows 50 to 100 cm tall. The leaves are 8-15 cm long, 2.5-5 cm wide, oblong-ovate with a pointed tip and a heart-shaped base. In September to October, the petiole emerges from the upper leaf axil on the branch and produces a concentrated inflorescence at the end, which produces 1 to 3 light reddish-purple flowers. The petiole is longer than the petiole. The corolla has a thick tubular lip with a short upper lip and three lobes on the lower lip, with the central lob larger than the other two lobes. The flower has four stamens and one pistil. The sepals are bell-shaped, but after flowering they become globular and cover the fruit. The fruit is a fruit consisting of one to three segments and is about 1 cm long. There are three species in the genus C. longipes (C. longipes), C. moschata (C. moschata), and C. yagiharana (C. yagiharana).

Origin of Japanese and scientific names
The species name "longipes" means "with a long handle," and was given by Dr. Tomitaro Makino, the same as the Japanese name. The genus name "chelone" is a compound of the Latin words "chelone (turtle)" and "opsis (similar).

Difference between Chelonopsis longipes and Chelonopsis moschata
Chelonopsis moschata grows in highlands, whereas Chelonopsis longipes grows along valleys in lowlands. The flower stalks of Chelonopsis longipes are longer and the flower color is darker in tanijakoso.
