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.
Zusammenfassung: Pócs, T., Müller, F. & Shevock, J. R. 2015. Ergänzungen zur Leber- und Hornmoosflora von São Tomé und Príncipe II, mit Neurolejeunea, einer für Afrika neuen Gattung. – Herzogia 28: 50 – 69.
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.
Resumo: Pócs, T., Müller, F. & Shevock, J. R. 2015. Adições à flora de hepática e antócero de São Tomé e Príncipe II, com Neurolejeunea, um novo género para a África. – Herzogia 28: 50 – 69.
Neurolejeunea breutelii é nova para a África, com uma nova var. africana. Três espécies são novas para a África ocidental, 16 para as Ilhas do Golfo da Guiné e 18 espécies de hepáticas e antóceros são reportadas como novas para a República de São Tomé e Príncipe. 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.
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.
The treatment of non epyphyllous Lejeuneaceae taxa was published inhe 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. Ngurumountains, 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.
A preliminary regional IUCN Red List for liverworts and hornworts is provided for Réunion (Mascarene archipelago), in accordance with the IUCN Red List criteria 3.1. A total of 327 species were assessed of which one species (Bryopteris gaudichaudii Gottsche) is considered to be regionally extinct (RE), fourteen species categorised as critically endangered (CR), eight species are endangered (EN), nine species are vulnerable (VU), eight species are considered Near Threatened (NT), and 177 species are at Least Concern (LC). Thirty-one species of liverworts reported on the island are threatened (CR, EN, VU), no hornwort are considered threatened. We divided the category “Data Deficient” into two categories: DDt (data deficient for taxonomy) and DDd (data deficient for distribution) to facilitate future assessment when data would be available. The current species threat analysis, which has generated the first regional Red List of bryophytes for Africa is hoped to promote future studies on the conservation of African bryophytes.
Abstract: 18 species of liverworts and hornworts are reported as new for the country of São Tomé and Príncipe, Gulf of Guinea, West Africa. An additional 8 species are reported as new for one of the islands of the country. Of this total, 13 species are new for Príncipe and 16 species new for São Tomé. The liverwort and hornwort flora for the country is now reported to have 147 species.
Resumo: 18 espécies de hepáticas e antóceros foram reportadas como novas para o país de São Tomé e de Príncipe, golfo da Guiné, África ocidental. 8 espécies adicionais foram reportadas como novas somente para uma das ilhas do país. Deste total, 13 espécies são novas para Príncipe e 16 para São Tomé. A flora de hepática e antócero do país possui atualmente 147 espécies.
