But flower-spike different, upper (male) flowers in ones or twos, not whorls of 4. Other features: Lowest flowers are female in whorls of 2-4, above these are hemaphrodite flowers, and at the top male flowers in ones or twos. Petals yellow streaked with red. Flower-spike has drooping tip in bud, unlike with Spiked Water-Milfoil |
