| Diapensiaceae | Pyxidanthera barbulata var. barbulata | Savanna Pyxiemoss, Common Pyxiemoss, Big Pyxie | Pine savannas, pine flatwoods, pocosin margins, edges of sandhill seepage bogs, primarily in mesic to hydric sites, in wet sands and peaty sands, occasionally extending to submesic sands, but generally with a permanently or seasonally high water table, often with Sphagnum. | NY (Long Island) south to NJ, and from se. VA south to n. SC. |  |
| Diapensiaceae | Pyxidanthera barbulata var. brevifolia | Sandhill Pyxiemoss, Wells's Pyxiemoss, Little Pyxie | On xeric sandhills, generally over deep sand, sand-clay mixtures, or plinthite, near the summits or on the upper slopes of sandhills, restricted to the Fall-line Sandhills region. | This species is endemic to a six-county area of the Fall-line Sandhills of NC and SC.
