Jamesoniella carringtonii—eine Plagiochila in Nepal mit Perianth

Abstract

Jamesoniella carringtonii (Balfour) Schiffn. is transferred to Plagiochila (P. carringtonii (Balfour) Grolle, comb.nov.). P. carringtonii ssp. carringtonii is regarded as an endemic subspecies of the British Isles and the Faeroes, whereasssp. lobuchensis Grolle, ssp.nov. with wholly entire leavesis restricted to Nepal and bears perianths. Jamesoniella carringtonii var. recurvata Nicholson is an independent not closely related species of Plagiochila (P. recurvata (Nicholson) Grolle, stat. et comb.nov.) from N.W.-Yünnan. P. recurvata and p. poeltii Inoue et GroUe, sp.nov. (from Nepal) probably belong to section Renitentes Carl. New differences between Jamesoniella autumnalis (DC.) Steph. and J. undulifolia (Nees) K. MOO., whichlatter is type of Biantheridion Grolle, sect.nov. Notes on the distribution of hepatics in Europe restricted to the cool euatlantic regions.

Miscellanea hepaticologica (71-80)

Abstract

(71) Cephalozia lunulifolia (Dum. 1831) Dum. 1835—lectotype (nov.): Mougeot & Nestler 432/e, c. per., BR—has to replace C. media Lindb. 1881. (72) Kymatocalyx stoloniferus Herz. 1950, syn.nov.: Solenostoma apertum Schiffn. & S. Arn. 1964. Because of the structure of its seta Kymatocalyx Herz. is newly placed within Cephaloziellaceae. (73) Lophozia capitata (Hook.) Boulay 1904 has to replace L. capitata (Hook.) K. Müll. 1950. (74) All Scandinavian records of Lophozia latifolia Schust. are rejected. (75) Notoscyphus macroscyphus Schiffn., N. fluviorum Schiffn. and N. paulensis Schiffn., all in Schiffner & S. Arnell (1964), are newly placed in synonymy of Lophocolea aquatica Herz. 1950. Notoscyphus Mitt s.str. remains palaeotropic in distribution. (76) Plagiochila corniculata (Dum.) Dum. validly dating as a species from 1831 has to replace P. tridenticulata Dum. validly dating as a species from 1835. (77) P. Punctata Tayl. 1846, syn.nov.: P. pitardii Steph. 1921.(78) P. spinulosa (Dicks. 1790) Dum., syn.nov.: P. maderensis Gottsche in Steph. 1904, and P. castellonis Gottsche in Steph. 1918. (79) Critical notes on Plagiochila sect. Plagiochila in Europe. List of names to be considered, with their types. Lectotype (nov.) of Jungermannia asplenioides L.: specimen in OXF corresponding with Dillenius. Hist. Musc. 482, tab. 69, fig. 5, Oxford, 1747. The large European taxon of section Plagiochila has to bear the name P. aspleniodes (L. emend. Tayl.) Dum. (= P. major (Nees) S. Arn., nomillegit.). The smaller plants of section Plagiochila in Europe perhaps are heterogeneous and may be called provisionally P. porelloides (Torrey ex Nees) Lindenb. s.amplo (= P. asplenioides sensu S. Arn., non (L.) Dum.). (80) Attention is called to four old Porella combinations by Pfeiffer (1855).     

Miscellanea hepaticologica 141-150

Abstract

141. Anomacaulis fiaccidus (Steph. 1917) Grolle c. n. has to replace A. hamatilobus (Grolle 1965) Schust. 142. Colura leratii (Steph. 1908) Steph. Has to replace C. apiculata Schiffn. ex Steph. 1916. 143. Herbertus sendtneri (Nees) Lindb. 1874 has to replace H. sendtneri (Nees) Evans 1917. 144. The redetected type of Herbertus stramineus (Dum.) Trev. in BR wholly justifies the recent usage of that name instead of H. aduncus auct. 145. The large styli of Jovetastella Tixier were misinterpreted as amphigastria. Jovetastella is reduced to subgeneric rank within Cololejeunea (Spruce) Schiffn., necessitating C. subg. Jovetastella (Tixier) Grolle n. st. et c. and C. paniensis (Tixier) Grolle c. n. 146. Lichenastrum Dill. 1811 is lectotypified with Jungermannia Ianceolata L. emend. Grolle, thus becoming a synonym of Jungermannia L. s. str. 147.Lophozia elongata Steph. has to replace L. elongata (Lindb. ex Kaal.) Steph. 148. Mannia triandra (Scop. 1772) Grolle c. n. has to replace M. rupestris (Nees 1817)Frye et Clark. A redetected type specimen of M archantia ludwigii Schwaegr. 1814 turned out to be Mannia triandra. Therefore Asterella gracilis (F. Web.) Underw. has to replace A. ludwigii auct. 149. Grimaldia chilensis Lindenb. ex Mont. 1839 was newly placed in synonymy of Sauteria berteroana Mont. 1839. 150. Telaranea nematodes (Gottsche ex Aust. 1879) Howe has to replace T. sejuncta auct., whereas the true T. sejuncta (Angstr. 1877) S. Arn. is a synonym of Arachniopsis diacantha (Mont. 1856) Howe. T. sejuncta yare breviseta (Herz.) Fulf. is still another species, thus the single record of T. nematodes or T. sejuncta from Juan Fernandez is rejected.

Mrican hepatics. XXXIV. Some little-known or new Lejeuneaceae

Abstract

Lejeunea aethiopica E. W. Jones, sp. nov., L. amaniensis E. W. Jones sp. nov., L. hepaticola Steph., and Cheilolejeunea cordistipula (Steph.) Grolle ex Jones, 397 comb. nov. (Strepsilejeunea cordistipula Steph., Pycnolejeunea angustiflora Steph., syn. nov.) are described.     

Morphological and phytochemical studies of Plagiochila papillifolia Steph., a Neotropical liverwort new to Europe

Abstract

The Neotropical liverwort Plagiochila papillifolia Steph. is conspecific with P. caespiticia Spruce ex Herzog (nom. inval.), P . deciduifolia Steph., P . solmsii Steph. and P . verruculosa R.M.Schust.; it is reported from the Azores, new to Europe. Morphologically it shows affinity with sect. Bidentes Carl; phytochemically, several of its lipophilic secondary metabolites are the same as those of P . retrorsa Gottsche, another Neotropical species reported only recently from Macaronesia.     

Miscellanea hepaticologica 201-210

Abstract

201. Calycularia crispula Mitt. new to Mexico and the whole America. It is the first record outside Asia. 202. A type study of Fimbriaria nana Lindenb. revealed that it is synonymous with Athalamia hyalina (Sommerf.) Hatt. 203. Fossombroniaceae Hazsl. 1885 has to replace Codoniaceae Klinggr.1858 nom. illeg., because Codonia Dum. 1822 is illegitimate. 204. Herzogobryumaterrimum (Steph.) c. n. (≡ Cephalozia aterrima Steph.) has to replace H. filarium Grolle 1975. 205. Korrnickia Steph. 1917 is regarded as a synonym of Symphyogyna Nees et Mont. 1836 and K. cylindrica Steph. 1917 is placed in synonymy of S. mexicana Steph. 1909.206. The detection of the perianth of Lophocolea spectabilis Steph. (≡ Heteroscyphus arnellii Fulf.) necessitates a transfer as Leptoscyphus spectabilis (Steph.) c. n. 207. All records of Preissia Corda from Latin America are rejected. P. barbata Herz. 1921 is referred to as syn. nov. of Marchantia chenopoda L. 1753. 208. Riccia crustata Trab. was validly published in 1916 already, but has been generally overlooked hitherto. 209. Symphyogyna brasiliensis. Nees et Mont. is widespread in the Neotropics and Africa. Several African names are treated as synonyms. 210. The monotypic genus Wiesnerella Schiffn. is newly recorded from New Guinea and the Mascarenes. The Mascarene record is the first one outside Asia.     

Plagiochila cucullifolia var. anomala var. nov. from Ecuador, with notes on discordant molecular and morphological variation in Plagiochila

Plagiochila cucullifolia Jack & Steph. var. anomala J. Heinrichs & Gradst. var. nov. is described and illustrated. The new variety is known from a single locality in southern Ecuador and differs from P. cucullifolia var. cucullifolia by the flat, not saccate leaves, somewhat smaller plant size and weaker leaf dentation. According to phylogenetic analyses of 35 nrDNA ITS1 and ITS2 sequences of Plagiochila, the two varieties of P. cucullifolia form a monophyletic lineage and are placed in a well supported clade together with five other species of Plagiochila sect. Hylacoetes: P. dimorpha Lindenb. & Gottsche var. ecuadorica (Inoue) J. Heinrichs, P. flabelliflora Steph., P. patriciae J. Heinrichs & H. Anton, P. macrostachya Lindenb. and P. turgida Herzog. Within Plagiochila, nrITS sequence variation is not concordant with morphological diversification. ITS sequences of Plagiochila cucullifolia s.str. and of P. dimorpha var. ecuadorica differ in only 23 aligned positions whereas two sequences of P. subplana Lindenb. differ in 86 aligned positions. Morphologically, P. cucullifolia s.str. and P. dimorpha var. ecuadorica differ in more than 20 characters and previously these two taxa were placed in separate genera. P. subplana phenotypes show considerable variation in leaf shape and dentation but the extremes are linked by numerous intermediates.     

Additions to the bryoflora of Réunion Island 3: new and interesting records from the Tropical Bryology Group (British Bryological Society)

Abstract

This contribution is a result of collaborative work based on the fieldwork organized during a workshop of the Tropical Bryology Group on Mascarene bryophytes in September 2008, and also from previous unpublished records of the authors. We add 35 new taxon records (17 mosses and 18 liverworts) as well as five other interesting records for Réunion Island (Mascarene Archipelago). Grimmia austrofunalis Müll. Hal., Sphagnum magellanicum Brid. subsp. magellanicum, Didymodon tectorum (Müll. Hal.) K. Saito, Anastrophyllum revolutum Steph. and Lejeunea exilis (Reinw. et al.) Grolle are reported for the first time for Africa. Syrrhopodon vardei L. T. Ellis, Ceratolejeunea papuliflora Steph. and Xylolejeunea grolleana (Pócs) X.-L. He & Grolle, previously known as endemic from Madagascar, are here recorded for Réunion. The latter species is also illustrated with SEM pictures.     

Cheilolejeunea oncophylla (Ångstr.) Orolle & Reiner comb. nov. (Lejeuneaceae), from the Neotropics

Abstract

Cheilolejeunea oncophylla (Ångstr.) Grolle & Reiner comb. nov. (basionym: Lejeunea oncophylla Ångstr.) is described and illustrated. Trachylejeunea dominicensis Steph. and Harpalejeunea verrucosa Herzog are shown to be synon):'ms.     

Distribution and synonymy of Plagiochila punctata (Taylor) Taylor, with hypotheses on the evolutionary history of Plagiochila sect. Arrectae (Plagiochilaceae, Hepaticae)

For a long time, Plagiochila (sect. Arrectae) punctata (Taylor) Taylor has been treated as an endemic of Atlantic Europe. Studies of larger specimen sets demonstrated that the species is widespread in mountainous regions of the Neotropics where it is known under several names including P. stolonifera Lindenb. & Gottsche, P. choachina Gottsche and P. patzschkei Steph. In tropical Africa P. punctata is established as Plagiochila subalpina Steph., nom. illeg. The sporophyte of P. punctata is described for the first time, based on material from Costa Rica. A maximum likelihood analysis of a nrITS sequence alignment with sequences of P. sects. Fuscoluteae (outgroup), Arrectae, and Rutilantes as well as of P. rubescens (Lehm. & Lindenb.) Lindenb. results in a tree with well bootstrap supported Arrectae and Rutilantes clades. ITS sequences of Plagiochila punctata from the Comoros and Zaire are placed in an unsupported monophyletic lineage together with P. punctata sequences from the British Isles and Ecuador. The species is nested in a robust clade with P. spinulosa (Dicks.) Dumort. and P. stricta Lindenb. The weak genetic separation of these three species indicates a recent diversification; the disjunct ranges may be the result of long range dispersal events. Plagiochila rubescens from southern South America is placed sister to P. sect. Arrectae. The latter section possibly originated from southern South American ancestors, diversified in tropical America after the uplift of the Andes and reached the Holarctics and tropical Africa by long range dispersal of diaspores.We are grateful to the curators and owners of the herbaria cited in the text for the loan of specimens, especially to Tamás Pócs, Volker Buchbender and Eberhard Fischer for their continuous support with recent collections from tropical Africa. David Rycroft kindly sent a duplicate of P. rubescens. Financial support of the Deutsche Forschungsgemeinschaft (grant HE 3584/1) is gratefully acknowledged.     

A morphological revision of the genus Herbertus S.Gray (Herbertaceae,Marchantiophyta) in Africa,including the East African islands

Abstract

The genus Herbertus S.Gray in Africa and the East African islands is revised. The division of the genus into two broad species complexes centred on H. dicranus (Tayl.ex Gottsche et al.) Trev. and H. juniperoideus (Sw.) Grolle is confirmed. H. capensis (Steph.) Sim, H. capillaris (Steph.) H. doggeltianus (Steph.) Demaret, H. lobatus (Steph.) Demaret, H. mascarenicus (Steph.) S.Arn., H. mollis (Steph.) Dusén, H. stuhlmannii (Steph.) Demaret and Schisma kilimandjarense Steph. are synonymous with H. dicranus. H. grossevittatus (Steph.) S.Arn. ex Grolle is synonymous with H. juniperoideus. Three new species are described: H. spicatus N.G.Hodgetts sp. nov., which is related to H. juniperoideus and appears close to the neotropical H. pensilis, with long, narrow leaf lobe apices and a sheathing leaf base; H. mauritianus N.G.Hodgetts sp. nov., also related to H. juniperoideus, has fewer basal slime papillae and the vitta bifurcating lower down; and H. pocsii N.G.Hodgetts sp. nov., which is related to H. dicranus but has setaceous leaf lobe apices composed of long, narrow cells. The relationships of the taxa and patterns of distribution, taking account of recent molecular work, are discussed.
