Triplett, J. K., A. S. Weakley, and L. G. Clark. 2006. Hill cane (Arundinaria appalachiana), a new species of bamboo (Poaceae: Bambusoideae) from the southern Appalachian Mountains. Sida 22(1): 79-95.
Taxonomic Comments
This taxon comprises material of more upland, dryer habitats than the other sympatric Arundinaria. These plants had long been suspected as distinct and are recognized as such by Triplett et al. (2006) based on the ecology and also on morphologic characters.

Rank Reasons
Arundinaria appalachiana is a long-lived perennial grass endemic to the southern Appalachian Mountains and upper Piedmont in the southeastern United States. It can be locally common and grows in a variety of upland oak-hickory forests and woodlands away from streams compared to its congeners, A. gigantea and A. tecta, though its overall range is smaller. This species can form large colonies from rhizomes and is likely fire-dependent to induce flowering, which has only been documented once. Fire suppression and habitat conversion are the biggest threats to this species.
Range Extent Comments
Arundinaria appalachiana occurs primarily in the southwestern end of the Blue Ridge Mountains, extending east, south, and west into adjacent provinces in northeastern Alabama, northern Georgia, western North Carolina, northwestern South Carolina, and eastern Tennessee in the southeastern United States (Weakley and the Southeastern Flora Team 2023).
Occurrences Comments
By applying a 1 km separation distance to herbarium specimen data and photo-based observation data documented between the years of 2006 and 2023, it is estimated that there are at least 219 extant occurrences known (iNaturalist 2023, SEINet 2023). However, anecdotal evidence suggests there are over 300 occurrences (Bradley, Crabtree, Schotz, Tessel, pers. comm., 2024).
Threat Impact Comments
Arundinaria appalachiana is potentially threatened by habitat conversion, fire suppression, and possibly hybridization, though there is insufficient data, including anecdotal accounts, to understand scope and severity of threats for this species. In the species's description, Triplett et al. (2006) noted very few fertile specimens, which, like other woody bamboos, this species flowers very infrequently and perhaps in response to fire. Fire suppression throughout this species's habitat may thus be a threat, although the plants are very long-lived and can likely persist for centuries (Triplett et al. 2006).
Ecology & Habitat

Habitat

Arundinaria appalachiana grows in upland oak-hickory forests and woodlands on mesic to xeric sites, sometimes on hillside seepages and along streams but nearly always on uplands (slopes, bluffs, and ridges) away from perennial streams (Triplett et al. 2006).

Reproduction

This species is "presumed to be wind-pollinated and probably have mechanisms to facilitate outcrossing, including stigmas that develop after pollen is shed (Judziewicz et al.1999). Typically in woody bamboos, the flowering period extends over several months, providing ample opportunity for wind pollination. Like other bamboos, Arundinaria reproduces extensively by rhizomes" (Triplett et al. 2010).
