Taxonomic results of the Bryotrop expedition to Zaire and Rwanda : 32., Bryaceae

16 species of Bryaceae collected during the Bryotrop expedition to Rwanda and Zaire were examined resulting in 7 new records for Central Africa

Data to the bryoflora of Mount Kenya, Kenya

194 species of bryophytes, belonging to 61 families are reported from Mount Kenya, of which 38 species are new for Mount Kenya and 30 records are new for the whole country, marked by * and ** respectively. The montane forests between 1600 and 3300m. asl., contain the greatest diversity of life forms and species. This is due to the abundant rainfall providing adequate humidity at relatively low temperature and altitude, coupled with frequent cloud cover. All vegetation belts above the montane forests experience large diurnal fluctuations in temperatures, intense solar radiation, added by the fact that the rainfall is relatively low and erratic or at times fall in the form of hail or snow resulting in a low diversity of species and life forms except in very sheltered habitats such as rock crevices in rocky outcrops. Solifluctions soil conditions occuring between 3850 and 4450m. asl. exhibit moss balls growth forms. The summits of Batian (5199m.), Nelion (5188m.) and Lenana (4985m.) harbour small cushions of Grimmia affinis and Andreaea cucullata. The greatest number of species are found in the wetter southern, south-western and south-eastern slopes unlike the drier northern, north-western and north-eastern slopes of the mountain. Species commonly found in the wetter areas are Bryum preussii, Bryum keniae, Prionodon ciliatus, Hypopterygium viridissimum, Plagiochila barteri, Plagiochila squamulosa, Radula recurvifolia, Porella hoehnelii, Dumortiera hirsuta while Pterogonium gracile, Leptodon smithii and Hedwigia ciliata are characteristic of the drier areas

Contributions toward a bryoflora of the Aberdare Range, Kenya

124 species of bryophytes, belonging to 46 families are reported for the Aberdare Mountains, of which 58 species are new for the Aberdares and 6 records are new for Kenya, indicated by * and ** respectively. The wetter, more humid southern and south-eastern parts of the range contain the greatest diversity of species, particularly in the montane forests while the drier northern part is poor in species

Contribution to the bryoflora of Kenya

109 species of bryophytes are presented from various localities in Kenya, among which are thirteen new records (marked with **) for the country

Bryophytes from Saiwa Swamp National Park, Kenya

57 species of bryophytes belonging to 30 families are reported from Saiwa Swamp National Park, of which 57 species are new for Saiwa Swamp National Park and 10 records are new for Kenya, indicated by * and ** respectively. Although small in surface area (15.5 sq.km.) the park represents an undercollected area in Kenya with a good diversity of bryophytes

A preliminary checklist of the bryoflora of the Taita Hills, Kenya

A checklist of the bryoflora of the Taita Hills (Kenya) containing 168 taxa in 40 families is presented. Whilst previously only 22 mosses and 39 liverworts were recorded for the area, this study extended our knowledge to 85 and 83 respectively. Twenty taxa are newly recorded for Kenya

Western Mount Kenya bryophytes-I

The bryophyte composition of the Western side of Mt. Kenya between 2,400 and 5,199 m was studied. Ninety-nine species were identified, 66 belonging to Bryopsida and 33 to Hepaticopsida. The greatest diversity in terms of species numbers and life forms comes from the mountain forests where ideal conditions of temperature, rainfall, humidity and altitude for bryophyte growth are found. This diversity decreases as altitude increases.Journal of East African Natural History Vol. 83 (1) 1994: pp. 5-1

East African bryophytes XIX. A contribution to the bryoflora of Kenya

Ten taxa are recorded, as new to the bryoflora of Kenya: Andrewsianthus bilobus, Cephaloziella kiaerii, C. transvaalensis, Chenia leptophylla, Cololejeunea minutissima, Colura kilimanjarica, Drepanolejeunea ternatensis, Kurzia irregularis, Lejeunea aloba and Syntrichia pagorum. Further two proved to be new for the whole of Africa, as Microlejeunea globosa and Hennediella stanfordensis. These two were probably introduced into Nairobi township area, similarly to Chenia leptophylla
