The lower lip may have one large to many small red to reddish brown spots (hence the name guttata, which is Latin for 'spotted'). [10] The opening to the flower is hairy.
It is variable in appearance. The prostrate or upright stem grows up to 30 centimeters long. The oppositely arranged leaves are mostly oval in shape and may reach 6 centimeters long. The tubular flower is yellow in color, its tube just a few millimeters wide and widening at the lobed mouth. It may be up to 2.6 centimeters long.
The flowers are nodding and the sepals usually yellow, but sometimes yellowish-pink or raspberry pink, reflexed, and 12–20 mm (0.5–0.8 in) in length. The petals are white or cream and 7–10 mm long, with the stamens extending beyond them. The nectar spurs are yellow to raspberry pink, slightly curved, and measure 10–20 mm (0.4–0.8 in). [3]
The flowers are bright yellow, 7–10 cm (2.8–3.9 in) across, with the typical iris form. The fruit is a dry capsule 4–7 cm (1.6–2.8 in) long, containing numerous pale brown seeds. I. pseudacorus grows best in very wet conditions, and is common in wetlands, where it tolerates submersion, low pH , and anoxic soils.
