Ditrichum flexifolium (Hook.) Hampe. 



Mlanje District: Mlanje Mountain; Luchenya Plateau, moist, shaded erosion 

 bank in grassland, 1900 ra., 16628. North Nyasa District: Nyika Plateau, shaded 

 bare soil on grasslands, 2400 m., 17328; ibid., moist peaty soil in thickets, 2400 

 m., 17192. 



DICRANACEAE 



Dicranella subsubulata (Hampe) Jaeg. 



Mlanje District: Mlanje Mountain; Luchenya Plateau, on bauxite soil of an 

 eroded shady bank, 1890 m., 16618; ibid., terrestrial in moist forest shade, 1890 

 m., 16725. 



Dicranella minuta (Hampe) Jaeg. 



Mlanje District: Mlanje Mountain; Luchenya Plateau, moist shaded erosion 

 bank in grassland, 2000 m., 16633. 



Campylopus inchangae (C. Mull.) Par. 



Mlanje District: Mlanje Mountain; Luchenya Plateau, terrestrial in semi-shade 

 under Widdringtonia trees, 1890 m., 16553; ibid., rotting stumps of Widdringtonia 

 trees, 1890 m., 16562; ibid., cushioned on a stump in semi-shade, 1890 m., 16592. 



Campylopus paludicola Broth. 



Mlanje District: Mlanje Mountain; Luchenya Plateau, lower trunk of tree in 

 forest, 1900 m., 16631. 



These plants agree well with the original description except for the armature 

 of the upper leaf-margin, which is here sharply serrate rather than minutely ser- 

 rulate as described and figured for the Rugege-Wald collection. 



Campylopus stramineus (Mitt.) Jaeg. 



North Nyasa District: Nyika Plateau, on low trees on grasslands, 2300 m., 

 17233. 



Evidently this is one of the smaller forms mentioned by Dixon in his remarks 

 on the plants from Mt. Kenia (Smithson. Misc. Coll. 69*: 10, 11. 1918). The 

 leaves are less than 4 mm. long and the stems quite short. The costa in section 

 shows a ventral row of large empty cells and a dorsal band of smaller cells with- 

 out stereids. 



Leucoloma rehmanni C. Mull, ex Par. 



Mlanje District: Mlanje Mountain; Luchenya Plateau, pale bright green, epi- 

 phyte in river bank forest, 1820 m., 16559; ibid., covering lower trunks of forest 

 trees, -in deep shade, 1890 m., 16539; ibid., on tree trunks in deep forest shade, 

 1890 m., 16621. 



CALYMPERACEAE 



Syrrhopodon obliquirostris C. Mull. 



Mlanje District: Mlanje Mountain; Luchenya Plateau, epiphytic in rain-forest, 

 1860 m., 16449.

Leptodontium squarrosum (Hook.) Par. 



North Nyasa District: Nyika Plateau, cushioned on exposed branches of trees, 

 2250 m., 17307, 17305. Mlanje District: Mlanje Mountain; Luchenya Plateau, epi- 

 phytic in forest, 1820-1850 m., 16587, 16679, 16685, 16814. Zomba District: Zomba 

 Plateau, abundant on rocks in edge of rain-forest, 1820 m., 16165. Cholo District:
