A key to the Colombian species of Holostipous Lejeuneaceae (Hepaticae) A key to the Colombian species of Holostipous Lejeuneaceae (Hepaticae)
No full textA synopsis and key emphasizing vegetative characters are provided for 72 species (in 34 genera) of Lejeuneaceae with undivided underleaves, recorded from Colombia and neighbouring areas. A brief statement on the altitudinal distribution and on the ecology of the species in Colombia is also provided. The checklist of the Hepaticae of Colombia (Gradstein & Hekking 1979) is updated; 10 species are added to the Colombian flora and 36 species names recorded from Colombia have fallen into synonymy. Se provee la sinopsis y la clave, con énfasis en carácteres vegetativos, para 72 especies (en 34 géneros) de Lejeuneaceae con anfigastros enteros para Colombia y regiones aledañas. También se suministra una breve información sobre la ecología y distribución altitudinal de las especies en Colombia. A la lista de Hepáticas de Colombia (Gradstein y Hekking 1979) se agregan 10 especies de la flora de Colombia, así mismo, 36 nombres de especies colombianas pasan a ser sinónimas.</p

No full textThe liverwort genus Cyrtolejeunea A. Evans is reduced to synonymy under Cheilolejeunea (Spruce) Schiffn. because of the existence of a series of intermediate species, including Cheilolejeunea insecta Grolle & Gradst. sp. nov. from Bolivia and Brazil and Cheilolejeunea chenii R.L. Zhu & M.L. So from eastern China. The new combinations, Cheilolejeunea holostipa (Spruce) Grolle & R.L. Zhu comb. nov. and C. suzannensis (Grolle) Grolle & R.L. Zhu comb. nov., are proposed
Santa María, líquenes, hepáticas y musgos: guía de campo
No full textilustraciones, fotografías, mapasEn este libro, Santa María , Líquenes, Hepáticas y Musgos, se recogen las experiencias de lo que pudiéramos llamar tres generaciones de estudiosos de la briología de Colombia, el investigador de mayor trayectoria, el profesor J. Aguirre-C., el doctor Jaime Uribe, discípulo de J. Aguirre-C. y de S. R. Gradstein, especialista en el estudio de las hepáticas de Colombia, con contribuciones de reconocida calidad, que también son textos muy aceptados a nivel internacional como la lista de las hepáticas de Colombia y varias flórulas.

TaxLink, a program for computer‐assisted documentation of different circumscriptions of biological taxa
No full textTaxonomic interpretations of species or other taxa may vary considerably among authors. A database program called TaxLink has been developed, which allows for a detailed visualisation of comparisons between different taxonomic concepts. The basic entities of TaxLink are "taxonyms" (= potential taxa. Berendsohn, 1995). TaxLink may store taxonyms with their references, synonyms, relationships between taxonyms, and nomenclatural status of names. Information can be vizualised on screen, printed, and retrieved as textdocument in Microsoft Word format
Studies on Lejeuneaceae subfam. Ptychanthoideae VI. A revision of Schiffneriolejeunea sect. Saccatae from Asia
No full textThe originally monotypic eastern Malaysian genus Schiffneriolejeunea Verdoorn 1933 has now become a widespread, pantropical group of about fifteen species by the inclusion of species from the genus Ptychocoleus Trev. nom. illeg. Six species are known from Asia, three of which constitute the sect. Saccatae (Verdoorn) Gradst. & Terken comb. nov. These are the widespread Schiffneriolejeunea tumida (Nees) Gradst., the eastern Malaysian S. cumingiana (Mont.) Gradst. and S. nymannii (Steph.) Gradst. & Terken comb. nov. Schiffneriolejeunea tumida is a rather polymorphic species in which two not sharply defined varieties may be distinguished: S. tumida var. tumida with more or less involuted leaf margins, and S. tumida var. haskarliana (Gott.) Gradst. & Terken comb. nov. with plane margins
Studies on Lejeuneaceae Subfam. Ptychanthoideae, V. A Review of the Species from Ceylon
No full textIn the spring of 1966, the junior author (H. Inoue) made a bryophyte collecting trip to Ceylon (now Sri Lanka) with the support of the Japan Society for the Promotion of Science. The collections have served as a basis for reviews of individual liverwort genera or families occurring in Ceylon, e.g. Frullania (Hattori, 1979) and Plagiochila (Inoue, 1979). The present paper deals with the species of Lejeuneaceae subfamily Ptychanthoideae, which comprises the more robust members of this large tropical family.
In his catalogue of the liverworts of Ceylon, Abeywickrama (1959) recorded 18 species of Ptychanthoideae, belonging to the genera Archilejeunea (1 sp.), Brachiolejemea (1 sp.), Lopholejeunea (2 sp.), Mastigolejemea (2 sp.), Ptychanthus (4 spp.), Ptychocoleus (5 spp.), Spruceanthus (1 sp.), Thysananthus (1 sp.), and Trocholejeunea (1 sp.). Unfortunately, his catalogue does not provide precise information on specimens or literature on which individual species records for Ceylon were based. Most of the species listed by Abeywickrama had been treated by Verdoorn (1934) in his monograph of Asiatic Ptychanthoideae. Some are now considered synonyms, however, whereas in other cases some doubts may be cast about the correctness of the identification. Since we have not been able to locate all specimens on which previous Ceylon records of Ptychanthoideae were based, the present review should be considered preliminary
Lophozia perssonii Buch & S. Arnell in Nederland
No full textThe first record of Lophozia perssonii for the Netherlands, from an old and deep limestone-quarry near Cadier en Keer, S. Limburg. Sterile L. perssonii grows here as a pioneer on shaded, calcareous tufa blocks together with Leiocolea badensis and other bryophytes. The differences with related species are discussed, and a description of the ecology is given
Studies on Lejeuneaceae subfam. Ptychanthoideae. I. Nomenclature and Taxonomy of Ptychocoleus, Acrolejeunea and Schiffneriolejeunea
No full textThe present paper is preliminary to a monographic treatment of the genera Acrolejeunea (Spruce) Schiffn. and Schiffneriolejeunea Verd. The main purpose of this paper is to reestablish Acrolejeunea as the nomenclaturally correct name of a genus of Lejeuneaceae to which in this century commonly the name Ptychocoleus Trev. was applied
