Discussion

Solmsiella biseriata is known from Jefferson County in Florida, Richmond County in Georgia and Iberia Parish in Louisiana.

A. Touw (1992) noted that Malesian collections came from man-made habitats; similar habitats in the Americas should be carefully examined. Solmsiella biseriata, to the casual observer or the uninitiated, can be mistaken for a small leafy liverwort, as reflected in the genus of the basionym. However, its dimorphic leaves, arranged in 4 rows, and cucullate calyptra will distinguish it from Erpodium domingense, which has more or less monomorphic leaves arranged in several rows and mitrate calyptra.
