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.     

African Hepatics. XXX: The genus Radula Dumortier

Abstract

Fifteen species of Radula from Africa and the Mascarenes are described, of which R. pseudoflaccida is new. The following species are newly reduced to synonyms: R. angustata Steph., R. capensis Steph., R. guineensis Steph., R. macroloba Steph., R. molleri Steph., R. pirottae Gola and R. spongiosa Steph. R. caespitosa Steph. is transferred from R. tabularis Steph. to R. madagascariensis Gottsche.

Habit, stem-structure, leaf-cuticle, perianth and spores provide valuable taxonomic characters which have received little or no attention and which show some degree of correlation. The range of forms shown by the lobule in a single species represent stages in its development.     

African Hepatics XXIX. Some new or little-known species and extensions of range

Abstract

Calypogeia afrocaernlea E. W. Jones, sp. nov. is described (type, from Kilimanjaro, in BM). Critical notes are provided on Cylindrocolea chevalieri (Steph.) Schuster, Simia S. Arnell, Syzygiella ruwenzorensis Steph., and Taxilejeunea pulchriflora Pearson. The following are new combinations: Cheilolejeunea surrepens (Mitt.) (basionym Lejeunea surrepens), Stictolejeunea balfourii (Mitt.) (basionym Lejeunea balfouri). Calypogeia fusca (Lehm.) Steph. is recorded from Cameroun and Ruanda; C. longifolia Steph. from Sierra Leone.     

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.     

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.     

African Hepatics: VIII. Diplasiolejeunea albifolia (Taylor) E. W. Jones comb.nov.

Abstract

The new combination Tetralophozia filiformis (Steph.) E. Urmi is proposed for Chandonanthus filiformis Steph. So far this species has been known only from Asia and N. America. Recent collections show it to occur also in Europe, in the Cantabrian Mts., Spain. Here it grows in sheltered places on siliceous rocks in oceanic conditions. From Tetralophozia setiformis (Ehrh.) Schljak. (=Chandonanthus setiformis) it is distinguished by its smaller size, the leaf lobes are always more than twice as long as wide and their margins are not inflexed towards the stem.

Grolle, C. convexa S. Arn., C. pocsii E. Jones, sp. nov., C. camerunensis S. Arn. Strepsilejeunea georgensis S. Arn. is a synonym of C. krakakammae.     

New records of bryophytes from the Canary Islands

Abstract

Two members each of the Adelanthaceae and Schistochilaceae and three of the Porellaceae are recorded from Mulanje Mountain, of which Adelanthus lindenbergianus (Lehm.) Mitt., Porella abyssinica (Nees) Trev. var. hoehnelii (Steph.) Pócs, Porella capensis (Gott.) Mitt. and P. subdentata (Mitt.) Steph. are first records for Malawi.     

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.

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.     

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.     

A contribution to the knowledge of epiphyllous bryophytes of Bioko Island (Equatorial Guinea), including additional remarks on non-epiphyllous species

Abstract

A collection of epiphyllous bryophytes from Bioko Island was investigated. It contained 57 epiphyllous bryophytes, comprising 55 hepatics and two mosses. Three taxa, Cololejeunea eustacei Pócs, Colura calderae Pócs and Lejeunea halei Robinson subsp. africana Pócs, are new to science. Cololejeunea papilliloba Steph. is new to Africa, five species of hepatics are new to West Africa, and an additional 31 species of hepatics are newly reported from Bioko Island. The second part of the paper deals with records of non-epiphyllous collections. Fourteen species are reported for the first time for Bioko Island. Actinodontium dusenii Broth. is made a synonym of Actinodontium streptopogoneum Broth. The following new combination is proposed: Wijkia rigidicaule (Müll.Hal. ex Broth.) Frank Müll., comb. nov. (Basionym: Acanthocladium rigidicaule Müll.Hal. ex Broth.).
