PLANTS COLLECTED IN NY AS ALAND

RH ACOFIL ACE AE 



Rhacopilum capense C. Mull. 



Kota-kota District: Nchisi Mountain, lower trunk of tree, 1550 m., 17050. 

 Cholo District: Cholo Mountain, base of tree and log in rain-forest, 1200 m., 

 11121, 11129. 



NECKERACEAE 



Porotrichum natalense C. Mull. 



North Nyasa District: Nyika Plateau, trunks of trees in montane forest, 2250 

 m., 11304. 



Porotrichum comorense Hampe. 



Cholo District: Cholo Mountain, seldom fertile, covering lower trunks of tree 

 in rain-forest, 1300 m., 11694. 



HOOKERIACEAE 



Daltonia minor Besch. 



Mlanje District: Mlanje Mountain; Luchenya Plateau, carpeting an old log in 

 deep forest, 1890 m., 76722. 



Daltonia patula Mitt. 



Mlanje District: Mlanje Mountain; Luchenya Plateau, amongst the tufted 

 branchlets of bamboos in forest, 1820 m., 16682; ibid., twigs of a forest bamboo, 

 1820 m., 16596. 



These collections seem to be inseparable from the type gathering from Peak 

 Clarence, Fernando Po, and the few plants from Usagara Mountains and Kili- 

 manjaro represented on the sheet in the Mitten herbarium. They are more robust 

 but structurally the same. As Mr. Brass' specimens are ample and in fine fruit 

 they are a valuable supplement to our meagre knowledge of this rare species. 



Lepidopilum lastii Mitt. 



Mlanje District: Mlanje Mountain; Luchenya Plateau, on bamboo twigs in 

 forest, 1820 m., 16501; ibid., epiphytic in forest, 1820 m., 16688. 



Through the kindness of the New York Botanical Garden I have been able to 

 compare these collections with the type of L. lastii from the Mitten herbarium. Ex- 

 cepting that the setae in the Nyasaland plants are slightly longer (6-7 mm. in- 

 stead of 3-4 mm.) the agreement is complete. It has been previously known only 

 from the original gathering from the Usagara Mountains. 



F ABRONIACE AE 



Rhizofabronia sphaerocarpa (Dus.) Fleisch. 



North Nyasa District: Nyika Plateau, on stem of tree-fern in montane forest, 

 2250 m., i7267. 



The occurrence of this delicate and beautiful little moss in Nyasaland is a 

 noteworthy fact. It has been found in Cameroon, Ruwenzori, and Usambara, but 

 the present collection extends the range appreciably to the southward. 



LESKEACEAE 



Rhegmatodon secundus Kiaer. 



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

 dense forest shade, 1890 m., 16531. 



BRACHYTHECIACE AE 



Brachythecium salebrosum Bruch., Schimp. & Gumb. 



Mlanje District; Mlanje Mountain; Luchenya Plateau, epiphytic in forest, 1820 

 m.. 16681.
