Delgadillo M., C. and R. H. Zander. 1984. Saito, K. 1973. Taxonomic position of the genus Neohyophila Crum. Zander, R. H. 1983. Zander, R. H. 1993.
Plants loosely caespitose.
Specialized asexual propagules absent. Spores yellow, weakly papillose. The shape of the dorsal stereid band of Plaubelia is semicircular, but flattened-lunate in Hyophila . No hydroid strand occurs in Hyophila involuta and that species often develops clavate, corniculate, stalked axillary propagula. The rosulate habit of Plaubelia is usually distinct from the elongate, densely foliate specimens of Hyophila involuta , although infertile stems of the former may be elongate and more sparsely foliate.
