Galium buxifolium is a rare species of flowering plant in the
Channel Islands of California, where it is known from about 26 populations on two of the islands.[1] It is a federally listed endangered species
of the United States.
This is a small
dioecious, but it may have unisexual and bisexual flowers on one plant, or all female or all bisexual flowers on a single plant.[1] It can reproduce sexually or vegetatively by sprouting new plants from its root crown.[1]
The fruit is a hairy nutlet.
This plant can be found on
Santa Rosa Island, which is situated between Santa Cruz and San Miguel Islands, but specimens have not been collected there since 1930.[2]
Threats to the species include invasive plant species, particularly plants that form thick groundcover, such as ice plant (Carpobrotus chilensis) and vinca (Vinca major).[1] Vinca has been experimentally controlled by hand-pulling and herbicide treatments.[2]
