Orontium aquaticum, Golden Club, or the floating Arum is a plant species endemic to the Eastern United States. Its native habitat extends from as south as Florida, to New York State. It grows in ponds, slow streams, and bogs and swamps.
The plant belongs to the family Araceae, as is clear from its inflorescence. The golden color stands out in the mostly dormant landscape of a bog in spring—Photograph taken in the New Jersey pinelands.
The plant is also called “never-wet.” As you can see here, the leaves are water repellent.
The plant has generated morphological confusion. If you are familiar with a peace lily, you would know that a modified leaf, a spathe surrounds an Arum inflorescence. The spathe is missing from the mature inflorescence. You may observe a green sheath early on in the development, which drops off as the spike matures. Engler had classified the structure as a spathe. We know now that that the small green enclosure was a sympodial leaf. The spathe is missing in this species.
