 IVHONV FAMILY. 



Trees or shrubs with very hard wood, alternate entire exstipulate leaves, and 

 dioecious polygamous or rarely perfect regular flowers, solitary or cymose in the 

 axils. Calyx inferior, 3-7-lobed, commonly accrescent and persistent. Corolla 

 gamopetalous, deciduous, 3-7-lobed, the lobes usually convolute in the bud. 

 Stamens 2-3 times as many as the lobes of the corolla in the sterile flowers, and 

 inserted on its tube, usually some imperfect ones in the pistillate flowers; fila- 

 ments short; anthers introrse, narrow, erect. Disk none. Ovary superior, 

 several- celled, in the staminate flowers rudimentary or none; ovules 1-3 in each 

 cavity, suspended; styles 2-8, distinct, or united below; stigmas terminal, some- 

 times 2-parted. Fruit a berry, containing several seeds, or but one. Seeds ob- 

 long, compressed or globose, the testa bony, endosperm copious, cartilaginous; 

 embryo small, usually straight; cotyledons large, foliaceous. 



About 6 genera and 275 species, mostly of tropical distribution.

 fruit Corolla urceolate in our species, 4-6-lobed. Stamens 8-20 in the sterile flowers, few 

 or none in the pistillate ones. Styles 2-6 in the pistillate flowers; ovary globose or ovoid, 

 its cavities twice as many as the styles. Ovary rudimentary in the sterile flowers. Berry 

 large, pulpy, containing 4-12 flat oblong hard seeds. [Greek, Zeus' wheat] 



About 160 species, abundant in Asia. Besides the following, another occurs in the southwest.
