Galium serpylloides agg. comprises a group of locally endemic, disjunct and vicarious taxa in the (sub)alpine zone of the W. Himalaya, from W to E:G. gymnopetalum, G. lahulense, G. serpylloides s. str.,G. saipalense, andG. nepalense. Four of these are new to science;G. serpylloides is newly typified. The main characters of the five species are compared and illustrated, their affinities and evolution are discussed, and a map of distribution is presented.Dedicated to Prof.K. H. Rechinger on the occasion of his 80th birthday. 相似文献

Four distinct species ofCortinarius referable to subg.Dermocybe are described from the Cooloola Sand-Mass, Queensland; two are formally recognized asC. alkalivirens, spec. nova andC. chromobasis, spec. nova, whilst notes are provided for the other two. Chemical methods and cladistic studies are applied and indicate a new section of the subgenus is required.Australodermocybe sect. nova is proposed. 相似文献

13 species of the lichen genusCatapyrenium are reported from South America. Five species (C. analogicum, C. andicolum, C. exaratum, C. lachneoides, andC. podolepis) are described as new. A key to the species known from South America is presented. Remarks on taxonomy, ecology and distribution of the species are given.Studies on the lichen genusCatapyrenium (Verrucariaceae) III.

The new species belongs toFestuca halleri agg. (F. ovina s. latiss.) and is diploid. Its habitat are alpine snow bed communities (Arabidetalia caeruleae) of the southern Alps, between the Brenta and Mt Cadria in the W and Mt Cavallo near Belluno in the E. Morphological, anatomical, epidermal, and ecological comparisons with related species suggest that it is closest to the vicariousF. rupicaprina in the N Alps. 相似文献

Alchemilla austriaca is a new species which belongs to the group ofA. demissa, A. frigens, A. longana, A. longiuscula, A. semisecta, andA. sinuata. The holotype specimen as well as leaf and flower details are illustrated (Figs. 1–3). A complete character analysis is given, differences and similarities of allied species are presented in two tables, and the position of the group within the genus is discussed.A. austriaca so far is known only from the Austrian Alps and mainly from the central ranges (distribution map: Fig. 4). Its wet subalpine and alpine habitats are characterized by species lists. 相似文献

A fourth species ofSclerorhachis, S. leptoclada
Rech. f., has been discovered in S. Khorasan. It differs from the three known species by its tender habit, rosette leaves with few short segments, extremely reduced stem leaves, and very small heads.Sclerorhachis with its four vicarious species confined to the most arid parts of the Iranian highlands is believed to belong to the paleoxeromorphics (Rechinger 1952).

Tillandsia carminea is a new, morphologically and ecologically distinct species, related toT. stricta
Solander, which occurs in the Serra dos Orgaos near Teresopolis, Brazil. It has been taken forT. rosea
Lindley, but new investigations have shown thatT. rosea is a synonym toT. stricta and thatT. carminea is a good and distinct species. 相似文献

There are few fossil remains that are assigned or compared toCitrus. A new and characteristic leaf from the Pliocene of Italy is described asCitrus meletensis and its systematic position within theRutaceae is discussed. Together with other sparse remains that are reviewed here it confirms the existence ofCitrus in the European Tertiary. 相似文献

Summary With 11 currently recognised species, the genusEriocnemis (Reichenbach, 1849) is one of the most diversified Andean trochilid groups occupying mainly open montane habitats such as the edges of cloud forest or páramos. On the basis of distributional and morphological patterns, this study highlights the geographical variation and biogeography of the taxon. Characteristics common to all these species are the greenish dorsal plumage, the conspicuous and mostly whitish tibial tufts, and a fairly pronounced tail bifurcation. With the help of plumage synapomorphies for a cladistic analysis (PAUP*), several species groups or superspecies can be distinguished: theE. vestitus group (incl.E. vestitus, E. godini, E. nigrivestis), theE. luciani group (incl.E. luciani, E. cupreoventris, E. sapphiropygia), and theE. alinae group (incl.E. alinae, E. mirabilis).E. glaucopoides, E. mosquera, andE. derbyi differ quite widely in morphology and ecological requirements from the other species. Three new subspecies are described,E. vestitus arcosi from southern Ecuador and northern Peru, andE. luciani baptistae from central and southern Ecuador. A previously overlooked specimen ofE. luciani from the Andes of Mérida represents the first species record for Venezuela, about 1100 km northeast of the main population range, and should be recognised taxonomically asE. luciani meridae, subsp. nov., on the basis of its unique plumage morphology and geographical separation. Additionally, the unique type ofE. ventralis (Salvin, 1891) is probably of hybrid origin (E. vestitus × cupreoventris). The genus may have evolved in the northern Andes, subsequently spreading southward and invading the central Andes. Its recent range and phylogenetic patterns indicate vicariance events as the major speciation factor inEriocnemis.In memoriam Dr. Luis F. Baptista (1941–2000) 相似文献

Based on pollen and floral morphology,Blechum grandiflorum is transferred toRuellia, and the nameR. mirandana is proposed for this species. A new species,Ruellia tuxtlensis, is described which is distinguishable fromR. mirandana by its longer spike and elliptic bracts. It is presently known only from the lowlands of Veracruz, Mexico. 相似文献

Four different strains ofLactobacillus delbrueckii subsp.bulgaricus (Ss1 and Yop12) andStreptococcus salivarius subsp.thermophilus (Ss2 and Yop9) were isolated from two different yogurt sources in Argentina. In medium containing different carbon sources: lactose, fructose, sucrose or glucose plus fructose, the growth of a mixed culture (Yop12+Ss2) shows stimulation ofS. thermophilus and inhibition ofL. bulgaricus with respect to pure cultures. Both microorganisms in mixed culture grew less well on glucose plus galactose. However, in medium with glucose or galactose, both microorganisms were stimulated. 相似文献
