Flood stalk

The  Flood Stalk  is a Halo Wars Flood structure. If you destroy it, it releases a couple of groups of infection forms. It seem to consist of a couple of Flood Growth Pods on a biomass stalk and this supports the action of releasing infection forms when harmed. Flood Stalks like Flood Eggs are benign and only act when harmed unlike in the case of Flood Eggs they will not release resources so can be ignored with no loss.

Trivia

 * The Rebel Leader skull on the Halo Wars level The Flood requires the player to kill 20 Flood Stalks.
