A re-examination of Orthothecium hyalopiliferum (Hypnales)
Orthothecium hyalopiliferum is morphologically distinct at the species level from O. intricatum on the basis of its silky soft appearance, the presence of very narrow lanceolate leaves with a leaf tip to leaf base ratio of 1:2 or less; and piliferous leaf tips that end in 3-6 single cells. Orthothecium hyalopiliferum is presently known only from the Chinese provinces of Guizhou, Sichuan, and Yunnan.
