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.     

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.     

Notes on Porella inaequalis (Gott,ex Steph.) H. Perss

Morphological aspects of Porella inaequalis (Gott, ex Steph.) H. Perss. an endemic species of Madeira are presented. For the first time the gynoecium is described. Androecia and sporophyte remain unknown. Some ecological details are given and the distribution of the species is mapped.     

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.

Type studies in the Lejeuneaceae. II. Pteryganthus,a new subgenus of Lopholejeunea

Lopholejeunea subgenusPteryganthus is described as new based upon the Mauritian plantL. sphaerophora (Lehm. & Lindenb.) Steph.Lopholejeunea utriculata Steph. from Madagascar is included as well.Lopholejeunea sinuata (Mitt.) Steph. is reduced to synonymy withL. sphaerophora. The two species of subgenusPteryganthus are compared withL. herzogiana Verd. andL. pullei Verd., two Malaysian species, with superficially similar lobule construction, but not of thePteryanthus type.

Abstract

Lejeunea obtusata Gott. is described and recorded from Madagascar, Mauritius, Tanzania, Ghana, Sierra Leone and probably Uganda. L. cantabrigiensis E.W. Jones sp. nov. is described from Cameroon Mountain. L. obtusistipula (Steph.) E.W. Jones, comb. nov. (Cheilolejeunea obtusistipula Steph.) is described from Sierra Leone.

Recent Bryological Literature, 68

Abstract

Five species of Colura are reported from Mulanje Mountain, of which four, C. ealyptrifolia (Hook.) Dum., C. digitalis (Mitten) Steph., C. hattoriana Pócs and C. tenuicornis (Evans) Steph. are new for Malawi. C. hattoriana is also reported new for mainland Africa. A key to sub-Saharan taxa is provided.     

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.     

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.     

Vittia salina L.Hedenäs & J.Muñoz,sp. nov., a new moss from Argentina

Abstract

A survey of the species of Campylopus Brid. reported from Sri Lanka (Ceylon) is presented. Of the 34 species that have been reported from this Island 16 are accepted at present. Campylopus nilghiriensis (Mitt.) Jaeg. is identical partly with C. goughii (Mitt.) Jaeg., partly with C. zollingerianus (C. Müll.) Bosch &; Lac., C. pseudogracilis Card. &; Dix. with C. goughii (Mitt.) Jaeg., C. caudatus (C. Müll.) Mont., C. reduncus (Reinw. &; Hornsch.) Bosch &; Lac. and C. trachythecius (C. Müll.) Jaeg. with C. comosus (Reinw. &; Hornsch.) Bosch &; Lac., C. herzogii Broth., C. subtricolor Lor. and probably also C. nodijlorus (C. Müll.) Jaeg. with C. aureus Bosch &; Lac., C nietneri (C. Müll.) Jaeg. with C. involutusz (C. Müll.) Jaeg., C. subgracilis Ren. &; Card. ex Gangulee and C. latinervis (Mitt.) Jaeg. with C. gracilis (Mitt.) Jaeg., and C. laetus (Mitt.) Jaeg. with C. savannarum (C. Müll.) Mitt. C. pterotoneuron (C. Müll.) Jaeg. is reduced to a variety of C. umbellatus (Arn.) Par. The occurrence of C. exasperatus Brid. on Sri Lanka could not be confirmed. Campylopus flagelliferus (C. Müll.) Jaeg. is reported as new to Sri Lanka.

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).
