- Comments
- Map incomplete and provisional. This taxon has not been widely recognized but is included in Fernald (1950, Gray's Manual) and Nesom's (1994, Phytologia 76: 193-274). It differs from var. racemosum by its few, long-peduncled heads on the ends of the inflorescence branches (vs. heads crowded in spikelike racemes in var. racemosum). Typical specimens are morphologically striking, but specimens of intermediate disposition exist and the two vars. appear to be totally sympatric in Virginia. Range-wide, they are partly sympatric, with var. subdumosum ranging further south. Further study is needed.
- Habitat
- Habitats are poorly known but appear to be similar to those of var. racemosum. Infrequent, or at least much less frequent than var. racemosum; specimens from the n. and c. Coastal Plain, n. and c. Piedmont, and n. Shenandoah Valley. Likely to be more widely distributed.
