Liriodendron tulipifera Linnaeus var. 1 . Coastal Plain Tulip-tree, Southern Yellow Poplar. Phen: Apr-Jun; Sep-Oct. Hab: Streamhead pocosins, pineland seepage swamps, small blackwater stream swamps. Dist: Sc. and se. NC south to Panhandle FL, west to s. MS.

ID notes: Fall color light yellow.

Origin/Endemic status: Endemic

Taxonomy Comments: Under study by Fetter, Weakley, & Poindexter (in prep.).

Other Comments: Its occurrence in fire-maintained, acid soil habitats in the Coastal Plain is surprising to people used to Liriodendron as a tree of mesic, rich soil forests with little or no fire. This variety is, however, a typical species of streamhead pocosins in the fall-line sandhills, growing with Pinus serotina, Nyssa biflora, and Acer rubrum, and often with scorch marks twenty feet up the trunk.
