As may be inferred from the tangled synonymy given above, this plant hashad an interesting history (See Bryologist for Nov., 1909). Although it soclosely resembles forms of Amhlyslegium Kochii as to be confused with it bygood students, I believe Austin was right in regarding it as a close relative of C. cbrysophyllum. It is a slender, lax, unbranched or little-branched plant, growingin springy or partially inundated places over decaying leaves, etc. The leavesare very distant, not squarrose, merely spreading, not otherwise very differentin typical forms from the stem leaves of C. cbrysophyllum. The leaves differ fromthose of related AmblsUegia in iieing broadly cordate-ovate and decurrent, sub- *See Fig. 175 for PLATE Caml>yliiim stellatum (From Bry.

From C. chrysopbyllum it differschiefly in its lax habit, distant leaves and little-branched plants, resembling ingross appearance AmblyUegium rather than Campylium. Small forms of Drepcvio-cladiis aduncus Kiieiffii are distinguished by their more stronglyexcavate leaf bases and more inflated alar cells; the leavesare usually less abruptly acum
