Thamnobryum cataractarum,a new species from Yorkshire,with observations on T. angustifolium and T. fernandesii

Abstract

Thamnobryum cataractarum sp. nov. is described from Yorkshire, England. It is most closely related to T. fernandesii from Madeira and is also similar to T. angustifolium from Derbyshire, England. The three species are compared, and the habitat of the new species is described. T. fernandesii and T. cataractarum are retained in Thamnobryum rather than in Crassiphyllum Ochyra.

A farewell to Tortella bambergeri (Pottiaceae) as understood over the last decades

Molecular sequence data provide convincing evidence that Tortella bambergeri (Schimp.) Broth., as understood over the last three decades, consists of two species. On the other hand, a careful investigation of the holotype of Trichostomum bambergeri Schimp. revealed its synonymy with Tortella tortuosa (Hedw.) Limpr. (in its current broad sense), which was confirmed by the molecular sequences of two plants from the Alps that were morphologically similar to the T. bambergeri type and that proved to be unrelated to the European plants currently so named. For T. bambergeri auct., two validly described names were located, T. fasciculata (Culm.) Culm., a suboceanic-submediterranean floristic element, and T. pseudofragilis (Thér.) Köckinger &; Hedenäs, comb. nov., a boreo-montane element. Lectotypes for these two names are designated. Beside molecular differences, the two species can be distinguished mainly by having differently shaped cells on the upper leaf margin and by differences in the orientation of the dry leaves. Distribution and ecology of these two taxa are discussed. A key to Tortella (Müll.Hal.) Limpr. species with quadrate superficial cells on the dorsal, upper costa is provided. Hybrid sporophytes in T. pseudofragilis, with T. tortuosa (Hedw.) Limpr. as the male parent, are discussed in the light of other observations, including an apparent hybrid T. pseudofragilis?×?inclinata from Sweden, suggesting that hybridisation may be important in the evolution within Tortella.

Trioza hopeae sp. nov. (Hemiptera: Triozidae): A pest on Hopea odorata (Malvales: Dipterocarpaceae) in Vietnam

Trioza hopeae sp. nov. is described and illustrated from Vietnam. Trioza hopeae develops on Hopea odorata, a valuable timber tree on which it causes serious damage by inducing leaf galls. The new species is closely related to Trioza minuta (Mathur) comb. nov. (from Ceropsylla Riley), an Indian species associated with Shorea robusta. Differences between the two species are discussed. Another five Indian species are transferred here from Ceropsylla to Trioza Foerster as T. ferruginea ( Mathur, 1975 ) comb. nov., T. fulvida ( Mathur, 1975 ) comb. nov., T. indica ( Kandasamy, 1986 ) comb. nov., T. longivenata ( Kandasamy, 1986 ) comb. nov., and T. parvus ( Kandasamy, 1986 ) comb. nov.

Occurrence of Sapindopsis (Platanaceae) in the Cretaceous of Eurasia

Three new species of the genus Sapindopsis Fontaine from Central Asia and western Siberia are described: S. neuburgae (Vachr.) Golovn., comb. nov., S. janschinii (Vachr.) Golovn., comb. nov., and S. kryshtofovichii (I. Lebed.) Golovn., comb. nov. Geographical and stratigraphic analyses have shown that the genus evolved in Eurasia from the Middle Albian to the Cenomanian, and was mostly restricted to the subtropics of the Euro-Sinian phytogeographic area from the Middle East to Russian Primorye and northern China. The are no reliable records of Sapindopsis from Europe. The migration of Sapindopsis from North America to Eurasia through the Bering Land Bridge was most probably related to the Early-Middle Albian climatic optimum.     

A morphological,caryological and morphometrical analysis of Teucrium euganeum Vis. and its allies

The aim of the present study is to clarify the taxonomic position of Teucrium euganeum Vis. vis à vis T.siculum (Rafin.) Guss. and T.scorodonia L. The study is based on an analysis of macro- and micro-morphological characters, type, and distribution of trichomes in different parts of the plant, chromosome counts, and a statistical analysis of such morphometric data. The results of the study allow one to consider the populations of the Euganean Hills (Padua, north-eastern Italy) as a sub-species of T.siculum, and, therefore, a new combination is proposed: Teucrium siculum (Rafin.) Guss. subsp. euganeum (Vis.) Tornadore, comb. et stat.nov.

Die sehr natürliche Gattung ist neben den charakteristischen Cystiden ausgezeichnet durch Repetobasidien.     

ESSENTIAL OILS AS TAXONOMIC AIDS IN THE CLASSIFICATION OF DICHANTHIUM PARVIFLORUM

Essential oil components and gross morphological characters are closely correlated in Dichanthium parviflorum (R. Br.) de Wet et Harlan (Gramineae) and related species. Different species, varieties, and geographical races, as well as hybrids between them, can be identified on the basis of absence or presence and quantity of essential oil components. The morphologically variable D. parviflorum was subdivided into four varieties: var. parviflorum, var. capilliflorum (Steud.) de Wet et Harlan comb. nov., var. mutispiculum (Ohwi) de Wet et Harlan comb. nov., and var. spicigerum (S. T. Blake) de Wet et Harlan comb. nov. These varieties differ from each other morphologically in having respectively racemes with 1-4 and awned, 3-5 and awned, 1-2 and awnlass, and 4-10 and awned spikelet pairs per raceme.     

Revision of the Endemic Hawaiian genus <Emphasis Type="Italic">Trematolobelia</Emphasis> (Campanulaceae: Lobelioideae)

Trematolobelia (Campanulaceae: Lobeliodeae) is a genus of semelparous pliestesial pachycaul rosette treelets endemic to the Hawaiian Islands. Eight species are re-cognized. The most widespread is T. macrostachys, found in the Ko‘olau Mountains of O‘ahu and on Moloka‘i and Maui. The remainder are single-island endemics: T. auriculata (Lna‘i); T. grandiflora (Hawai‘i); T. kaalae, comb. et stat. nov. (Wai‘anae Mountains of O‘ahu); T. kauaiensis (Kaua‘i); T. rockii (Moloka‘i); T. singularis (Ko‘olau Mountains of O‘ahu); and T. wimmeri (Hawai‘i).     

SYSTEMATICS OF TRIPSACUM DACTYLOIDES (GRAMINEAE)

Tripsacum dactyloides (L.) L. extends across the range of this genus from about 42°N to 24°S latitude in the New World. It is recognized to include T. dactyloides var. dactyloides (North America), var. meridonale deWet et Timothy (South America), var. hispidum (Hitchc.) deWet et Harlan comb. nov. (Mesoamerica) and var. mexicanum deWet et Harlan var. nov. (Mesoamericana). The genus is divided into sections Tripsacum and Fasciculatum. Mesoamerican members of section Tripsacum are classified into T. bravum Gray, T. dactyloides (L.) L., T. intermedium deWet et Harlan spec, nov., T. latifolium Hitchc., T. manisuroides deWet et Harlan spec. nov. and T. zopilotense Hern,*** et Randolph. A key to the species of section Tripsacum is presented.     

Arvernella microclada Hugonnot & Hedenäs (Amblystegiaceae), a new minute species from France,requiring a separate genus

Abstract

Arvernella microclada Hugonnot & Hedenäs is described from several localities in the Massif Central of France (Auvergne). This diminutive, autoicous, pleurocarpous moss has strongly prorate distal ends of the leaf lamina cells and straight and erect inner perichaetial leaves. It bears a superficial resemblance to small Heterocladium Bruch & Schimp. species, especially H. flaccidum (Schimp.) A.J.E.Sm. or weak phenotypes of H. wulfsbergii I.Hagen. Other small confervoid species, like Platydictya jungermannioides (Brid.) H.A.Crum or Serpoleskea confervoides (Brid.) Loeske differ in several respects, most notably in the absence of abaxial leaf lamina cell prorations, but also in rhizoid topography (Platydictya) and leaf orientation and leaf margin denticulation (Serpoleskea). Arvernella microclada grows in subalpine tall-herb communities and Fagus sylvatica L. mountain woods on small lava blocks on cold, unstable, and steep scree slopes. The restricted known geographical distribution may be of conservation concern.     

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.
