Plate 1 — 1. Transverse section of leaf of Polytrichum commune showing lamellae on the upper surface. 2. Leaf of Dicnemoloma showing papillose lower surface. 3. Leaf of Loptobryum pyriforme. 4. Leaf of Pterygophyllum dentarum with forked nerve and denticulate margin. 5. Leaf of Tortula princeps showing the nerve excurrent in a long dentate, flexuose, piliferous point. 6. Leaf of Hypnum cupressiforme, strongly curved and nerveless. 7. Leaf of Acrocladium auriculatum with short nerve and conspicu…

Leaf of Pterygophyllum dentarum with forked nerve and denticulate margin. 5. Leaf of Tortula princeps showing the nerve excurrent in a long dentate, flexuose, piliferous point. 6. Leaf of Hypnum cupressiforme, strongly curved and nerveless. 7. Leaf of Acrocladium auriculatum with short nerve and conspicuous alar areas. 8. Leaf of Fissidens leptocladus showing the nerve reaching the apex, vaginant leaf base (stippled) and thickened margins. 9. Leaf of Polytrichum commune showing dentate margins and upper surfaces opaque owing to the numerous longitudinal lamellae. 10. Leaf of Calyptopogon mniodes showing the apical mass of gemmae on the upper surface. 11. Leaf of Catharomnion ciliatum showing the remarkable ciliation. 12. Leaf of Hymenodon piliferus showing piliferous apex and nerve not reaching the apex. 13. Leaf of Rhizogonium mnioides with thickened, dentate margins. 14. Leaf of Cladomnion ericoides, nerveless, plicate and with recurved apiculus. 15. Leaf of Ctenidium pubescens showing the margins dentate almost to the base. 16. Leaf of Dicranoloma dicarpum with strongly spinulose upper margins. 17. Branch leaf of Sphagnum cuspidatum. 18. Sphagnum: part of a branch leaf surface, strongly magnified to show the long chlorophyllose cells enclosing the larger hyaline ones which are strengthened with ‘spirals’ or cell wall thickenings. 19. Capsule of Polytrichum juniperinum and front view of its mouth showing the (ruptured) circular membrane held in place by the 64 short teeth. 20. Capsule of Tortula princeps, erect, with twisted peristome rising from the entire basal part. 21. Capsule of Ceratodon purpureus, inclined and ribbed. 22. Capsule of Bryum truncorum, pendulous with conical opercuium. 23. Capsule of Weisia viridula, erect, with short peristome teeth. 24. Capsule of Conostomum pusillum, striate and horizontal. 25. Capsule of Polytrichadelphus magellanicus with operculum. 26. Capsule of Trematodon suberectus, inclined with long neck. 27. Capsule of Hypnum cupressiforme, inclined and with conicomamillate operculum. 28. Capsule of Ptychomnion aciculate, inclined and striate with the strikingly long operculum. 29. Capsule of Leptobryum pyriforme. 30. Capsule of Orthotrichum hortense, erect and ribbed with short, recurved outer peristome. The inner peristome consists of eight filiform processes which remain more or less horizontal across the mouth, but may be soon lost.
