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.
Hawaiian lobelioids The Hawaiian lobelioids are a group of flowering plants in the bellflower family, Campanulaceae, all of which are endemic to the Hawaiian Islands. This is the largest plant radiation in the Hawaiian Islands, and indeed the largest on any island archipelago, with over 125 species. The six genera can be broadly separated based on growth habit: "Clermontia" are typically branched shrubs or small trees, up to 7 m tall, with fleshy fruits; "Cyanea" and "Delissea" are typically unbranched or branching only at the base, with a cluster of relatively broad leaves at the apex and fleshy fruits; "Lobelia" and "Trematolobelia" have long thin leaves down a single, non-woody stem and capsular fruits with wind-dispersed seeds; and the peculiar "Brighamia" have a short, thick stem with a dense cluster of broad leaves, elongate white flowers, and capsular fruits.
