Hypericum annulatum is a species of flowering plant in the family Hypericaceae. It is closely related to Hypericum montanum which is its sister species.
Taxonomy
Hypericum annulatum was first described in 1827 by Moris in Stirp. Sard. volume 9. The holotype and isotype were both collected in Sardinia.[1]
Subspecies
Hypericum annulatum has three subspecies:
- Hypericum annulatum subsp. afromontanum
- Hypericum annulatum subsp. annulatum
- Hypericum annulatum subsp. intermedium
Description
The species is a perennial herb that grows 0.2-0.75 meters tall. Its stems are green to reddish in color.[2]
Medical use
Hypericum annulatum contains a newly discovered isocoumarin called annulatomarin. This modestly inhibits the growth of human chronic myeloid leukaemia LAMA-84 cells.[3]
