| Distribution | Present in the southeastern Coastal Plain, north only to Bladen and Onslow counties.
This species has a small range, limited to the Southern Atlantic coast, from southeastern NC to northeastern FL. | |
| Abundance | Rare, known from just 10 sites, of which eight are still extant, according to the NCNHP database. This is a State Threatened species. | |
| Habitat | This species requires wetlands over calcareous material -- such as marl -- usually in relation to pinelands. It can occur in wet pine savannas over marl, but more sites are in adjacent, somewhat disturbed soil, such as ditches and firebreaks near to natural savannas. |
| Phenology | Blooms and fruits between April and October. | |
| Identification | This species has a cluster of lanceolate basal leaves, with attenuated bases to a long petiole about 2-3 inches long. The blades are about 4-5 inches long and 3/4-inch wide, with several obvious parallel veins. The few flowering scapes are rather tall, about 9-10 inches on average. The spike covers the top half of the stalk, but in this species the flowers are scattered along the stalk such that the stalk is visible between most of the flowers. The clearly visible stalk/scape between the flowers distinguished this rarity from the quite common and statewide P. virginica, which has the typically very densely packed flowers within the spike. | |
