OBDEB XVII. AMARANTOIDE/E. 



Herbs with simple exstipulate leaves, and small inconspicuous (mostly 

 greenish) axillary solitary or clustered perfect or unisexual flowers. 

 Calyx of 35 hypogynous more or less scarious persistent sepals, occa-

 almost chaffy bracts. Corolla 0. Stamens usually 5 or more, distinct or 

 monadelphous. Stigmas 2 or 3, sessile on an undivided style. Fruit

 mingled with the pistillate in the same cluster. Sepals distinct or 

 united at base, seldom less than 3 or more than 5, more or less scarious, 

 erect, or the tips spreading. Stamens as many as the sepals, distinct. 

 Stigmas linear. Utricle ovate, 2 3 beaked, circumscissile or indehiscent
