Key to Moraceae
Tree, unarmed; monoecious or dioecious. Stem: buds scaly; stipule scars obscure, not encircling stem. Leaf: alternate, occasionally clustered with inflorescences, unlobed or 3–5-lobed, toothed, 3–5-veined from base, deciduous. Inflorescence: catkins, ± pendent, peduncled. Pistillate flower: style deeply 2-parted. Fruit: of many achenes within fleshy calyces, resembling blackberries.
± 20 species: temperate, warm temperate northern hemisphere. (Latin: mulberry) [Whittemore 2006 Sida 22:769–775] Wind-pollinated; Morus nigra, black mulberry, waif in urban areas.
Plant 10–15 m. Leaf: petiole 5–35 mm; blade 5–12 cm, ovate, coarsely toothed, abaxially glabrous or hairy only in axils of and on major veins, largest lobes generally 0–3, occasionally on 1 side, shallow to deep. Fruit: 1–2.5 cm, fleshy, white to ± pink or red-black.
