Dicranum scoparium

Maier, Eva & Price, Michelle J., 2014, Georg Bojung “ Scato ” Lantzius-Beninga and his contributions on the anatomy of moss capsules: a transliteration from the original German texts, Boissiera 67, pp. 1-79 : 36

Dicranum scoparium (Tab. LVIII. Fig. 10-13. Tab. LIX. 14).

At about the same place as the annulus is visible, instead of sixteen, thirty-two large peristome cells, two of them together are built as one big cell seen in the mosses examined until now; see Fig. 11. pp; a little bit nearer to the apex of the capsule where the peristome disappears totally only sixteen of them may be seen; compare Fig. 12 and 13.

The base of the peristome itself is formed from a coarse tissue composed by considerably thickened cells constituting a strong connection with the outer capsule membrane; see the transverse section Fig. 10. pp, the longitudinal section Fig. 14. x and y. Somewhat higher above, the thickening of the membranes is concentrated on the side of the peristome cells that turn towards the inner side of the capsule, Fig. 11. pp, then the thickening becomes smaller and smaller and divides into two cords at half the height of the peristome, [original page 576] Fig. 12. pp, to finally finish somewhat below the apex of the capsule, Fig. 13. pp. The structure of the capsule above the separation of the teeth is essentially comparable with that described for Barbula ( Fig. 12). *)

The annulus is formed by considerably small, flattened cells (Tab. LIX. Fig. 14. a).
