Are Berchemia and Howea both genus of plants?
Howea Howea is a genus of two palms, "H. belmoreana" and "H. forsteriana", both endemic to Lord Howe Island, Australia. "H. forsteriana" in particular is commonly grown as an indoor plant in the Northern Hemisphere, and the two species form the mainstay of the island's palm seed industry and more importantly its trade in newly germinated seedlings. The palms are also cultivated on Norfolk Island, where seeds are produced for export.
Hornungia Hornungia is a small genus of plants in the mustard family. It currently contains three species that have previously been classified as members of other genera, including "Hutchinsia" and "Pritzelago". The genera, and sometimes several others, are usually treated as synonyms.
