Discussion | All three varieties of Torreyochloa pallida grow in swamps, marshes, bogs, and the margins of lakes and streams. They are usually morphologically distinct, and tend to have different geographic ranges. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
The range of Torreyochloa pallida var. pallida extends from southeastern Manitoba to north of Lake Superior and Maine, and south to Missouri and Georgia. Torreyochloa pallida var. pallida can be difficult to distinguish from T. pallida var. fernaldii. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
