Xanthium orientale subsp. riparium
Xanthium orientale subsp. riparium is a robust, adaptable plant thriving in riparian zones with spiny burrs. Its broad, ovate leaves and tall stature, often reaching head height, allow it to compete effectively for sunlight. Xanthium orientale subsp. riparium's burrs play a pivotal role in seed dispersal, catching onto passerby, asserting its presence along waterways, and contributing to its invasive potential in favorable conditions.
