Notes     (Last Modified On 3/16/2009)
general taxon notes:
The characters that separate Racomitrium ericoides from the other species in the Racomitrium canescens complex are: 1) primary stems elongate and slender, pinnately branched with numerous short branches; 2) branch leaves often contorted when dry, with twisted hyaline hair-points; and 3) leaf cells distinctly papillose and alar cells clearly differentiated. In Asia, Racomitrium ericoides often is treated as a variety of R. canescnes (Noguchi 1974). Heinonen (1971) considered its pinnately branched stems, percurrent leaf costa, and small papillae of leaf cells to be distinguishing features from R. canescens.
