(188.) B. inclinatula, C. M. & Kindb. (n. sp.) Canadian Musci, No. 512.

Dioecious. Tufts laxly coherent, yellowish green. Stem indistinct, or 0.5 cm. high, not branching. Leaves cirrhate-crisped and rigid when dry, suberect and nearly straight when moist, not undulate, from a thin ovate-oblong base attenuate, nearly sublinear, acute or suddenly pointed, very papillose; margins involute, cucullate above; costa yellow pellucid, excurrent in an often denticulate point. Perichetial leaves much broader and longer than the other, whitish, from a long lanceolate base subulate; cells narrow, linear also above. Capsule narrow-cylindric, nearly straight, suberect; peristome long, several times convolute.

This species resembles rather the European Barbula inclinata (Hedw. f.) than B. tortuosa, which has a larger capsule, longer leaves, taller stems, etc.
