B. convoluta Hedw. In good fruit. 
Trichostomum mutabile vax. littorale Dixon (7. littorale Mitt.), 
st. Recorded, as 7’. mucronatulum, in Highth Ann. Report o 
Missouri Bot. Garden, 1897, p. 57. 7. mucronatulum, however, 
proves to be only a slender form of this plant. 
Bryum murale Wils., c.fr. The leaf margin is rather widely 
recurved, a character which I have noticed in other southern 
specimens from Tunis, Algeria, and Madeira.
