Abstract: Pócs, T., Müller, F. & Shevock, J. R. 2015. Additions to the liverwort and hornwort flora of São Tomé and Príncipe II, with Neurolejeunea, a genus new to Africa. – Herzogia 28: 50– 69. Neurolejeunea breutelii is new for Africa, with its new var. africana. Three species of liverworts are new for West Africa, 16 species for the Gulf of Guinea Islands and 18 species are reported as new for the country of São Tomé and Príncipe. Furthermore 18 liverwort species are new for Príncipe and four species are new for São Tomé. The liverwort and hornwort flora for the country now stands at 191 species. Colura benoistii is a new synonym of Colura obesa.

Neurolejeunea breutelii wird erstmals aus Afrika angegeben und var. africana neu beschrieben. Drei Arten sind neu für Westafrika, 16 Arten sind neu für die Inseln im Golf von Guinea und 18 Arten von Leber- und Hornmoosen werden erstmals aus dem Staat São Tomé und Príncipe angegeben. Darüber hinaus werden 18 Arten als neu für Príncipe und 4 Arten als neu für São Tomé gemeldet. Die Zahl der aus dem Land bekannten Leber- und Hornmoose konnte auf 191 Sippen vergrößert werden. Colura benoistii ist ein neues Synonym von Colura obesa.

Além disso, 18 espécies são novas para a Ilha do Príncipe e 4 espécies novas para a Ilha de São Tomé. A flora do país possui agora 191 espécies de hepáticas incluindo as antóceras. Colura benoistii é um novo sinónimo de Colura obesa.

 

 

 

 

Abstract

 

Capillolejeunea (Lejeuneaceae), known only from the East African Islands, is resurrected. It is characterized by and easily separated from Drepanolejeunea by the unbroken basal vitta of 3−5(−9) ocelli in leaf lobes, absence of scattered ocelli in leaf lobes, outer lateral margin of the upright underleaf lobes with a tooth, and single, unicellular tooth of the leaf lobule. The Madagascarian Drepanolejeunea geisslerae is transferred to Capillolejeunea. Capillolejeunea is the only liverwort genus endemic to Africa. A key to known species of Capillolejeunea is provided.

 

 

Note

 

The treatment of non epyphyllous Lejeuneaceae taxa was published in  he first part of the Central African BRYOTRO results (Pócs 1993b). Anyhow, a nice material collected on tiny twigs (partly from fallen canopy branches), from the W edge of Nyungwe Forest Reserve, in a wet tyoe of montane rainforest at 2000 m altitude, remained unidentified. As this collection contained a number of species, which did not occur int he previous Lejeuneaceae treatment and are partly new to Rwanda or even to science, we think it is worthwile to enumerate them in this chapter.

 

 

Summary. A new species of giant Lobelia (L. morogoroensisK nox & P6cs) is described that grows at relatively low altitudes on cliffs and in dry semi-deciduous woodlands on mountains near Morogoro, Tanzania. The morphology and phenology reflect the plant's relatively xerophytic ecology.

 

Abstract. During the past 5 years intensive bryological explorations were carried out in Tanzania with special emphasize on hitherto undercollected areas (e.g. Nguru  mountains, Mafia Island, unknown accesses of Mount Kilimanjaro and Meru) and on special habitats (e.g. rocky semi-desert or heath vegetation and alkaline tolerant epiphytic vegetation along the Rift Valley). These collections (above 8000 numbers) resulted in numerous records, some of them new to the African continent and at least 8 species new to science. The data point to interesting phytogeographical links and help to explain the evolution of the flora of East African volcanoes and crystalline mountains. Hitherto unknown oil bodies of more than 50 liverwort species were investigated. This paper does not give a full account of these studies but only provides examples to illustrate the above points.
