MEMOIRS OF THE NEW YORK BOTANICAL GARDEN [Vol. 8, No. 3 



Rhynchostegium brachypterum (Hornsch.) Jaeg* 



Kota-kota District: Nchisi Mountain, lower trunk of a tree in rain-forest, 1550 

 m., 17049. 



ENTODONTACEAE 



Erythrodontium subjulaceum (C. Mull.) Par. 



Cholo District: Cholo Mountain, exposed trunk of a rain-forest tree, 1200 m., 



17833. 



Entodon dregeanus (Hornsch.) C. Mull. 



Cholo District: Cholo Mountain, base of tree in rain-forest, 1200 m., 17728; 

 ibid., on a dead log in rain-forest, 1200 m., 17784. Zomba District, Zomba Plateau, 

 epiphytic on riverbank trees, 1400 m., 16073. 



Trachyphyllum fabronioides (C. Mull.) Gepp. 



Kota-kota District: Chia, base of trees in sandy Brachystegia woodlands, 480 



m., 17556. 



SEMATOPHYLLACEAE 



Sematophyllum dregei (C. Mull.) Bartr., comb. nov. 

 Hypnum dregei C. Mull. Syn. 2: 311. 1851. 



Mlanje District: Mlanje Mountain; Luchenya Plateau, epiphytic on forest under- 

 growth tree, 1890 m., 16830; ibid., on a shaded log in forest, 1890 m., 16726; 

 ibid., on lower trunk of a Widdringtonia tree, 1890 m., 16555; ibid., terrestrial in 

 semi-shade under Widdringtonia tree, 1890 m., 16556. Zomba District: Zomba 

 Plateau, covering trunks of trees in riverine rain-forest, 1450 m., 16207. North 

 Nyasa District: Nyika Plateau, on decaying wood in montane forest, 2250 m., 

 17305. 



In the Bryophyta of South Africa Simm lists a long series of synonyms for this 

 species but apparently it has never been included in Sematophyllum before. The 

 distinctions between Rhaphidorrhynchium and Sematophyllum seem to me to be 

 too slight to be of generic value. 



Sematophyllum caespitosum (Hedw.) Mitt. 



Mlanje District: Mlanje Mountain; Luchenya Plateau, on granite boulders in bed 

 of forest shade, 1820 m., 16595. 



HYPNACEAE 



Mittenothamnium cavifolium (Rehm.) Bartr., comb. nov. 



Eurhynchium cavifolium Par. Index 441. 1895. 



Mfcrothamnium cavifolium (Rehm.) Dix. Jour. Bot. 53: 21. 1915. 



Mlanje District: Mlanje Mountain; Luchenya Plateau, covering rocks in bed of 

 a forest stream, 1890 m., 16723; ibid., creeping on a log in forest, 1890 m., 

 16693; ibid., on lower trunks of forest trees, 1850 m., 16680. Zomba District: 

 Zomba Plateau, covering moist rocks in rain-forest, 1400 m., 16072. Kota-kota 

 District: Nchisi Mountain, on dead wood in rain-forest, 1500 m., 17048. 



As Cardot does not include this species in his long list of citations (Rev. 

 Bryol. 40: 20-22. 1913), it seems necessary to validate the new combination. 



Mittenothamnium cygnicollum (Hampe) Card. 



Mlanje District: Mlanje Mountain; Luchenya Plateau, lower trunks of trees in 

 deep forest shade, 1890 m., 16617. 



POLY TRICH ACE AE 



Pogonatum aloides (Hedw.) Beauv. 



Mlanje District: Mlanje Mountain; Luchenya Plateau, moist clay erosion banks 

 on grassland, 2000 m., 16657.
