Abstract
The authors made the first comprehensive bryological collection on the forest-covered Chyulu Range in south-eastern Kenya. Although these hills are of young volcanic origin and do not belong to the so called “Eastern Arc” mountains, they offer a high diversity of habitats from dry Acacia-Commiphora bushland to montane mist forest and thus a relatively rich bryophyte flora: from the 79 species recently recorded, 13 are new to the flora of Kenya. The new combination Plagiochila kiaeri var. myriocarpa is made.
