Inflorescece tight packed, bristly look, cylindrical shape . One to 5 spikes, all thick cylindric, ¾ to about 1½ inches long, about ½ inch in diameter. The terminal spike is mostly pistillate (female) with a few staminate (male) flowers at the base (gynecandrous). Lateral spikes, when present, are usually all pistillate on slender, erect to ascending stalks, sometimes with staminate flowers at the base. Spikes may be clustered together at the tip of the stem but are not typically crowded. At the base of each lateral spike is a leaf-like bract, usually much over-topping the terminal spike.
