Seven species of Radula are reported from the Galapagos Islands, including Radula santacruziana spec. nov. The majority of the species are common and widespread in the neotropics; two (including the new species) are endemic to the Galapagos. R. cornucopiae Spruce and R. mollis Lindenb. et Gott. are reduced to synonymy, resp. under R. episcia Spruce and R. quadrata Gott. et al.
A preliminary treatment of the Central American species of Octoblepharum (Musci: Calymperaceae)
(1991)
The species of Octoblepharum occurring in Central America have been critically examined. Six are recognized as valid species: O. albidum, O. cocuiense, O. cylindricum, O. erectifolium, O. pulvinatum and O. stramineum. Synonyms are given for these species: O. longifolium = O. albidum; O. mittenii, O. fragillimum, O. pellucidum and =O. pulvinatum var. angustifolium are synonyms of O. cocuiense; O. juruense and O. densum = O. pulvinatum and O. purpureo-brunneum = O. stramineum. All species are widely distributed in the area except for O. cylindricum and O. stramineum that are known only from Belize and Panama respectively.
The aim of this short and selected reference list is to guide bryologists in the very scattered African literature when they try to identify specimens, as no standard bryofloras are available for the whole of Tropical Africa. The idea to compile such a reference list was raised during the Tropical Bryology Workshop held by the British Bryological Society, in the Botany School of Cambridge University, on the 21st of September 1990. The list is based on the senior author’s private library and files. We hope that the publication and distribution of such a list, even if incomplete, will prove to be useful for the future taxonomic and floristic works in Tropical Africa with special reference to the Bryologia Africana Project. We also hope that it will encour- age further collecting and identification by those who are not well versed in or do not possess the very diversified taxonomic literature on African bryo- phytes.
A survey of the literature and a few unpublished identifications of recent collections indicate that 426 taxa have been reported from Costa Rica, including Cocos Island. The distribution of each taxon is indicated by province and parameters are given for most localities within each province.
A synopsis is provided of 88 species in 17 genera currently recognized in Lejeuneaceae subfamily Ptychanthoideae sensu lato (including Nipponolejeunea) of Asia. Taxonomic novelties include Thysananthus flavescens (Hatt.) comb. nov. (for Mastigolejeunea flavescens (Hatt.) Mizut.), Spruceanthus macrostipulus (Steph.) comb. nov. (for Archilejeunea macrostipula (Steph.) Verd.) and the reduction of Platylejeunea Mizut. to synonymy under Lopholejeunea.
Twenty-eight species of epiphyllous liverworts were identified from twenty-five sites in Kowloon Peninsula, Hong Kong. Twenty-four of these species are new records to Hong Kong, while four of them are new epiphyllous records to the Chinese mainland. The majority of the sites are located between 30-200 m above sea level, representing the lowest altitude of epiphyllous liverworts found in the Chinese mainland. Characteristics of the host plants bearing epiphyllous liverworts are briefly discussed. The following new combination is proposed: Cololejeunea pseudolatilobula (Chen & Wu) But & Gao comb. nov. (Pedinolejeunea pseudolatilobula Chen & Wu).
88.Campylopus hildebrandtii (C. Müll.) Jaeg. is reported as new to Ethiopia. 89. The combination Campylopus flexuosus (Hedw.) Brid. var. incacorralis (Herz.) J.-P. Frahm is validated. 90. Campylopus sedgwickii Dix., a species hitherto regarded as endemic to Sri Lanka, is recognized as a synonymous with C. recurvus (Mitt.) Jaeg. 91. The Campylopus fragilis complex in SE-.Asia has been revised. It consists of C.. fragilis (Brid.) B.S.G. in southern China, C. goughii (Mitt.) Jaeg. occurring from southern India to Sikkim and Bhutan and C. zollingerianus (C. Müll.) Bosch & Lac. occurring from Indonesia to the Philippines and also in Hawaii. Campylopus zollingerianus has proved to be the legitimate name for C. boswelii (C. Müll.) Par. and C. crispifolius Bartr. and not for C. goughii. All three species are distinguished mainly by the shape of the upper laminal cells only and accordingly, C. goughii and C. zollingerianus are placed as geographical vicariant races as subspecies to C. fragilis.
