Taxonomy
Hypericum iwate-littorale was first described by Hideo Koidzumi, a Japanese botanist, in the Journal of the Plants of Iwateken (J. Pl. Iwateken) in 1937.[1] Arika Kimura doubted the validity of the species, however, and placed it as a synonym of Hypericum pseudopetiolatum in subsect. Erecta. In 2003, as a part of his monograph of the genus Hypericum, Norman Robson restored H. iwate-littorale to the status of species and placed it in series Hypericum because of its raised stem lines with gland dots. He noted its similarities to Hypericum tosaense, but decided its minor differences in appearance and wide separation geographically warranted its inclusion as a separate species.[3]
The species' current placement within the genus Hypericum can be summarized as follows:[4]
- Hypericum subg. Hypericum
- Hypericum sect. Hypericum
- Hypericum subsect. Hypericum
- Hypericum ser. Hypericum
- Hypericum subsect. Hypericum
- Hypericum sect. Hypericum
