Belongs within: Euphorbiaceae. Euphorbia is a very large genus of flowering plants, most diverse in drier parts of the tropics. Species are diverse in appearance, including herbs, trees and cactus-like succulents. Flowers are minute but are borne in inflorescences subtended by modified leaves, cyathophylls, that may resemble brightly-coloured petals. Some species are popular ornamentals, such… Continue reading Euphorbia

Belongs within: Malpighiales. The Picrodendraceae are a pantropical group of trees and shrubs bearing characteristic spiny pollen. Characters (from Flora of Victoria): Trees or shrubs, lacking latex, monoecious or dioecious. Leaves usually alternate (rarely opposite or whorled), simple to palmate, petiolate; stipules present or absent. Inflorescences axillary, cymose, racemose, spicate or paniculate, bracteate. Flowers regular,… Continue reading Picrodendraceae
