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.
Erica Erica is a genus of roughly 860 species of flowering plants in the family Ericaceae. The English common names "heath" and "heather" are shared by some closely related genera of similar appearance. The genus "Calluna" was formerly included in "Erica" – it differs in having even smaller scale-leaves (less than 2–3 mm long), and the flower corolla consisting of separate petals. "Erica" is sometimes referred to as "winter (or spring) heather" to distinguish it from "Calluna" "summer (or autumn) heather".
