|discussion=<p><i>Imbribryum alpinum</i> is a relatively rare boreal-temperate species characterized by narrow, shiny-metallic red leaves and incrassate, elongate distal laminal cells; capsules are rare. Most reddish plants similar to this species in the western United States do not conform well to this set of characters. Instead, most collections have red, broadly ovate leaves, shorter distal laminal cells, and short-excurrent costae. This material cannot be referred to either <i>I. alpinum</i> or <i>I. muehlenbeckii</i>, and apparently represents an undescribed species. Reports from southern Africa need to be verified as other red-colored species occur in the Southern Hemisphere. The Alaska collection is from St. Lawrence Island.</p>
