- Comments
- T. pusillum var. monticulum was named based on specimens from Rockingham and Augusta Counties. Results of extensive morphological and molecular studies of the T. pusillum complex, however, do not support it's recognition. Nevertheless, transplants maintain differences in flowering time compared with var. virginianum (C.E. Stevens, pers. comm.) and the consistently large, rounded leaves lend a different aspect to populations of the montane plants.
- Habitat
- Most frequent on hummocks in braided seepage along small streams in southeastern Virginia, where the canopy oftens includes Liriodendron, Magnolia virginiana, and Acer rubrum; also in low mesic forests, wet flatwoods, bottomland forests, alluvial swamp hummocks, and non-riverine swamp "islands" of this region. Montane populations are on acid ridgecrests (Augusta & Rockingham cos.) and in a mafic fen (Grayson Co.). Trillium pusillum is rather widely distributed but rare in the s. and c. Coastal Plain, and very rare in the mountains.
