Are both genus, Goldenseal and Breynia, endemic to the same continent ?
Goldenseal Goldenseal (Hydrastis canadensis), also called orangeroot or yellow puccoon, is a perennial herb in the buttercup family Ranunculaceae, native to southeastern Canada and the eastern United States. It may be distinguished by its thick, yellow knotted rootstock. The stem is purplish and hairy above ground and yellow below ground where it connects to the yellow rhizome. The plant bears two palmate, hairy leaves with 5–7 double-toothed lobes and single, small, inconspicuous flowers with greenish white stamens in the late spring. It bears a single berry like a large raspberry with 10–30 seeds in the summer.
Knobby seahorse The knobby seahorse or short-head seahorse (not to be confused with the Short-snouted seahorse), Hippocampus breviceps, is a species of fish in the Syngnathidae family. It is endemic to Australia. Its natural habitats are open seas, shallow seas, subtidal aquatic beds, coral reefs, estuarine waters, intertidal flats, coastal saline lagoons, and karsts.
