The basal eudicots are a group of 13 related families of flowering plants in four orders: Buxales, Proteales, Ranunculales and Trochodendrales. [1] [lower-alpha 1] Like the core eudicots (the rest of the eudicots), they have pollen grains with three colpi (grooves) or other derived structures, [4] and usually have flowers with four or five petals (sometimes multiples of four or five, sometimes reduced or fused). [5] Unlike other eudicots, they sometimes have flowers with petals in twos or multiples of two. [6]

Contents

The basal eudicots include trees, shrubs, woody vines and herbaceous plants. [7] Cultivars of Buxus are used for hedges and topiary, and the high-quality wood is commonly used for decorative carvings and musical instruments. [8] The sacred lotus is the national flower of India and Vietnam, and the waratah is the floral emblem of the Australian state of New South Wales. [9] The opium poppy, Papaver somniferum , a source of morphine, was cultivated thousands of years ago in Mesopotamia. [10] Macadamia nuts are mainly grown in Hawaii and Australia. [11]

The orders Dilleniales and Gunnerales are basal within the core eudicots. Species of Gunnerales often have serrate (serrated) leaves, with flowers similar to those of Buxales. The epidermis and hairs on species of Dilleniales are often full of silica. [12] [13]

Family and a common name [13] [lower-alpha 2] Type genus and etymology [lower-alpha 3] Total genera; global distributionDescription and uses Order [13] Type genus images
Dilleniaceae (guineaflower family) Dillenia , for Johann Jacob Dillenius (1684–1747) [16] [17] 11 genera, throughout the tropics and extending into Asia and Australia [16] [18] Shrubs, trees, woody vines and a few herbaceous plants. Dillenia and Hibbertia species are grown as ornamentals, and some Dillenia fruits are edible. [19] [16] Dilleniales [16]
Gunneraceae (giant-rhubarb family) Gunnera , for Johan Ernst Gunnerus (1718–1773) [20] 1 genus, in the Southern Hemisphere and low northern latitudes [21] [22] Small to very large herbaceous plants, usually perennials, with nitrogen-fixing bacteria. The genus is planted along pond edges in many temperate gardens. [23] [20] Gunnerales [20]

<span class="mw-page-title-main">Saxifragaceae</span> Family of flowering plants in the Eudicot order Saxifragales

Saxifragaceae is a family of herbaceous perennial flowering plants, within the core eudicot order Saxifragales. The taxonomy of the family has been greatly revised and the scope much reduced in the era of molecular phylogenetic analysis. The family is divided into ten clades, with about 640 known species in about 35 accepted genera. About half of these consist of a single species, but about 400 of the species are in the type genus Saxifraga. The family is predominantly distributed in the northern hemisphere, but also in the Andes in South America.
