Description

Family Moraceae

Trees , shrubs , vines , or rarely herbs, frequently with milky or watery latex, sometimes spiny . Stipules present, frequently caducous . Leaves alternate, rarely opposite; petiole often present and well-defined; leaf blade simple , sometimes with cystoliths , margin entire or palmately lobed , venation pinnate or palmate. Inflorescences axillary , frequently paired , racemose, spicate , capitate, or rarely cymose , sometimes a fig or syconium with flowers completely enclosed within a hollow receptacle. Flowers unisexual (plants monoecious or dioecious), small to very small. Calyx lobes (1 or) 2-4(-8), free or connate , imbricate or valvate . Corolla absent. Male flowers: stamens as many as and opposite to calyx lobes (except in Artocarpus), straight or inflexed in bud; anthers 1- or 2-loculed, crescent-shaped to top-shaped; pistillode (rudimentary sterile pistil) often present. Female flowers: calyx lobes usually 4; ovary superior, semi-inferior, or inferior, 1(or 2) -loculed; ovules 1 per locule, anatropous or campylotropous; style branches 1 or 2; stigmas usually filiform . Fruit usually a drupe, rarely an achene, enveloped by an enlarged calyx and/or immersed in a fleshy receptacle, often joined into a syncarp. Seed solitary; endosperm present or absent.

Between 37 and 43 genera and 1100–1400 species: widespread in tropical and subtropical areas, less common in temperate areas; nine genera and 144 species (26 endemic, five introduced ) in China.

Economically, the most important species are those of Morus and Maclura associated with the production of silk . Some species in Broussonetia, Maclura, and Morus are important for paper making; some species in Artocarpus, Ficus, and Morus have edible fruit; and some species of Artocarpus and Broussonetia are used for furniture or timber.[1]

Genus Broussonetia

Trees , deciduous; sap milky . Terminal buds surrounded by bud scales. Leaves alternate, opposite, or whorled ; stipules caducous , free . Leaf blade ovate , lobed or entire, margins dentate ; venation appearing palmate or weakly 3-veined from base . Staminate inflorescences pedunculate , cylindric spikes; pistillate inflorescences short-pedunculate, globose capitula. Flowers: staminate and pistillate on different plants . Staminate flowers : sepals 4, connate at base; stamens 4, inflexed . Pistillate flowers: sepals 4, connate, forming tube ; ovary superior, stipitate , 1-locular; style unbranched. Fruits globose; each drupelet partly protruding from its enlarged calyx. x = 13.

Species 7-8: North America, Asia, and Pacific Islands (Polynesia).[2]
