egg-shaped. Style short, terminal. Stigma awl-shaped, or egg- 
shaped, oblique, downy at one side, mostly solitary, rarely 2, per- 
manent. Fruit (fig. 5.) sessile, inversely egg-shaped, beaked, dry, 
of 1 , rarely 2, cells. Nut (fig. 7.) solitary, egg-shaped. Embryo 
cylindrical, straight, in the centre of a mealy albumen. Common 
Receptacle globose, naked. 
Distinguished from other genera, in the same class and order, by 
the dense, round heads or spikes ; the calyx of 3 sepals, without a 
corolla ; and by the dry, 1-seeded fruit.
