Narrative
Powdery Thalia is native to wetlands in the Mississippi Delta, but due to habitat disruption is now rarely found growing in the wild. It is classified as an obligate wetland plant in the regions in which it is found, but it can tolerate dry conditions during the summer.

Leaves are large, ovate-lanceolate to elliptic-lanceolate, blades mostly 15-36 cm long by 6-13 cm wide, with petioles up to 8-9 cm long. The inflorescence is terminal composed of paired spikes with zig-zagged axes. Flowers are perfect, paired, subtended by two bracts. Sepals 3; petals 3, purplish; staminodia purplish and petaloid, the medial one largest and having a fertile stamen. The ovary is inferior with 3 locules.

Description:
Increase of plants from a known source location. Source population seeds were collected from plants growing at 202 N. Andrews Ave., Cleveland, MS but the plants themselves had been collected about 10 years earlier in Washington County, MS. No deliberate genetic modifications were made to the source material. Seed provided was collected from plants in growing ponds at the Plant Materials Center.
