Peduncle a quarter to half an inch high. Calyx concealed by the perichætial leaves. Ĝrev. FERN JUNGERMANNIA. J. scalaris. Schrad. Hook. which has often been mistaken for J. lanceolata, Linn. Hook. t. 18. a species which abundantly differs, not only in the absence of stipule, but in the large and naked calyx, and is at least a very doubtful native of Britain. J. lanceolata. E. Bot. Prof. Hooker considers J. scalaris of Schmidel to be no more than the gemmiferous state of J. Trichomanis, which has not unfrequently been so misunderstood. Abundant, upon a loamy soil, in woods, wastes, and hedge banks. P. April-Oct. E.)
