[Perennial herb] shrub, [vine] tree, generally with milky juice; monoecious or dioecious. Leaf: alternate [opposite], petioled, generally simple, entire to lobed, evergreen or deciduous; stipules present. Inflorescence: raceme, spike, head, or flowers enclosed in thick receptacle, axillary. Flower: unisexual or bisexual, small, ± radial; sepals generally 4, free or fused at base; petals 0; stamens generally 4, opposite sepals; ovary generally superior, 1-chambered, style simple or 2-parted. Fruit: achenes many within fleshy calyces or surrounded by fleshy inflorescence receptacle.
37 genera, 1100 species: tropics, subtropics, some temperate; many cultivated (Ficus, fig; Artocarpus, breadfruit, jackfruit; Morus, mulberry). Insect- or wind-pollinated. —Scientific Editors: Douglas H. Goldman, Bruce G. Baldwin.
Key to Moraceae
Tree, thorny; dioecious. Stem: buds scaly; stipule scars obscure, not encircling stem. Leaf: alternate, or clustered with inflorescences, entire, deciduous; major veins pinnate. Inflorescence: ± erect, spheric; staminate an umbel or umbel-like raceme, > 1 per axil, peduncled; pistillate a head, 1 per axil, sessile. Pistillate flower: style simple. Fruit: spheric, bumpy, of many achenes within fleshy calyces, yellow-green [red].
± 12 species: warm parts of America, Africa, Asia, Australia. (William McClure, American geologist, 1760–1840) Wind-pollinated.
Plant to 20 m; thorns to 3 cm. Leaf: petiole 1–4 cm; blade 3–14 cm, ovate to lance-oblong, dark green, sparsely soft-hairy. Fruit: 9–15 cm diam, yellow-green, densely irregularly warty.
Streambanks, disturbed areas; < 440 m. Great Central Valley, South Coast, Western Transverse Ranges; native to south-central United States. Widely planted; fruit inedible. Much less thorny with age. Apr–Jun [Online Interchange]
Unabridged note: Fruits fall unripe with the seeds still immature, the fruit then ripening on the ground and the seed maturing over the next several months.
