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.     

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 (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.

Response of epiphytic bryophytes to simulated N deposition in a subtropical montane cloud forest in southwestern China

A field manipulation experiment was conducted in a subtropical montane cloud forest in southwestern China to determine the possible responses of epiphytic bryophytes to increasing nitrogen (N) deposition from community to physiology level, and to find sensitive epiphytic bryophytes that may be used as indicators for assessing the degree of N pollution. N addition had significantly negative effects on species richness and cover of the epiphytic bryophyte community. Harmful effects of high N loads were recorded for chlorophyll, growth, and vitality of the species tested. The decline of some epiphytic bryophytes may result from detrimental effects on degradation to photosynthetic pigments. Bazzania himalayana (Mitt.) Schiffn., Bazzania ovistipula (Steph.) Mizut., and Homaliodendron flabellatum (Sm.) Fleisch. are candidates in atmospheric nitrogen monitoring. Epiphytic bryophytes in the montane cloud forest are very sensitive to increasing N deposition and often difficult to recover once they have been destroyed, providing early detection of enhanced N pollution for trees or even the whole forest ecosystem. The inference that increasing N pollution may lead to loss of biodiversity is a concern to the developing economy in western China, and should alert the government to the adverse impacts caused by increased industrial pollution during the process of China’s West Development.     

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.

Annotated checklist of Senegalia and Vachellia (Fabaceae: Mimosoideae) for the Indian subcontinent

An annotated checklist of Senegalia Raf. and Vachellia Wight & Arn. taxa for the Indian subcontinent is presented, following the fragmentation and retypification of the former broadly defined genus Acacia Mill. The countries encompassed by this study include Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan and Sri Lanka. All indigenous species (and a few introductions) in this region previously referred to Acacia belong to Senegalia and Vachellia. All Acacia s.s. taxa are introduced (principally from Australia) and are not included in the study. There are 22 species of Senegalia (21 indigenous, 1 introduced; representing 23 taxa) and 21 species of Vachellia (12 indigenous, 9 introduced; representing 27 taxa) currently recognized for the subcontinent. The largest country, India, has most species. This checklist complements that which was recently provided for these genera in southeast Asia and China. Two names formerly recorded for the Indian subcontinent are excluded, namely, Senegalia intsia (L.) Maslin is a nomen confusum and Acacia pennata subsp. hainanensis (Hayata) I. C. Nielsen is now known to be restricted to southern China and Vietnam. Acacia eriantha Desv. is an unresolved name. The following new combinations are made herein: Senegalia tanjorensis (Ragup., Thoth. & A.Mahad.) A.S.Deshpande & Maslin, Vachellia campbellii (Arn.) A.S.Deshp., & Maslin and V. pseudowightii (Thoth.) A.S.Deshpande & Maslin. A lectotype has been selected for Acacia pennata var. canescens Graham ex Kurz (= Senegalia pennata (L.) Maslin).     

Mesozoic origin and ‘out-of-India’ radiation of ricefishes (Adrianichthyidae)

The Indian subcontinent has an origin geologically different from Eurasia, but many terrestrial animal and plant species on it have congeneric or sister species in other parts of Asia, especially in the Southeast. This faunal and floral similarity between India and Southeast Asia is explained by either of the two biogeographic scenarios, ‘into-India’ or ‘out-of-India’. Phylogenies based on complete mitochondrial genomes and five nuclear genes were undertaken for ricefishes (Adrianichthyidae) to examine which of these two biogeographic scenarios fits better. We found that Oryzias setnai, the only adrianichthyid distributed in and endemic to the Western Ghats, a mountain range running parallel to the western coast of the Indian subcontinent, is sister to all other adrianichthyids from eastern India and Southeast–East Asia. Divergence time estimates and ancestral area reconstructions reveal that this western Indian species diverged in the late Mesozoic during the northward drift of the Indian subcontinent. These findings indicate that adrianichthyids dispersed eastward ‘out-of-India’ after the collision of the Indian subcontinent with Eurasia, and subsequently diversified in Southeast–East Asia. A review of geographic distributions of ‘out-of-India’ taxa reveals that they may have largely fuelled or modified the biodiversity of Eurasia.     

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.     

Notes on some African hepatic genera 1–5

The present study deals with five genera of hepatics in Africa, Isotachis Mitt., Anastrophyllum (Spruce) Steph., Tritomaria Schiffn. ex Loeske, Gymnocoleopsis (Schust.) Schust. and Lophozia (Dum.) Dum. All African populations of the genus Isotachis Mitt. are considered to be one species, I. aubertii (Schwaegr.) Mitt. Four species of Anastrophyllum (Spruce) Steph. (s.l.), A. auritum (Lehm.) Steph., A. piligerum (Nees) Spruce, A. subcomplicatum (Lehm. et Lindenb.) Steph. and A. minutum (Schreb.) Schust., and two species of Tritomaria Schiffn. et Loeske, T. camerunensis S. Arnell and T. exsecta (Schrad.) Schiffn. ex Loeske occur in Africa. Gymmocoleopsis multiflora (Steph.) Schust. represents a genus and species hitherto unreported for the African flora. Finally, five Lophozia (Dum.) Dum. species, L. argentina (Steph.) Schust., L. capensis S. Arnell, L. decolorans (Limpr.) Steph., L. hedbergii S. Arnell and L. tristaniana (S. Arnell) Váňa, are reported from central and southern Africa; two of these (L. argentina (Steph.) Schust. and L. decolorans (Limpr.) Steph.) represent the first reports from Africa.
