Cynoglossopsis somaliensis
H. Riedl, sp. nov., is described as a new species of the hitherto monotypic genusCynoglossopsis
Brand which is closest related toCynoglossum L. but has to be included inBoraginoideae-Eritrichieae from the way the nutlets are attached to the gynobasis. 相似文献

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

The phycobiont of all species ofLempholemma analyzed is attacked by haustoria. The haustoria of these five species ofLempholemma and of two species with unknown apothecium but with a thallus quite similar toLempholemma are described. They show distinct morphological and functional characters which allow species delimitation.

Karschia destructans
Tobler is recognized as a synonym ofBuellia schaereri
De Not. This species is not a parasitic fungus but a lichen that suffers when growing together withChaenotheca chrysocephala (Ach.)Th. Fr. orChaenotheca phaeocephala (Turn.)Th. Fr. subsp.alpina (Nádv.)Schmidt.

Morphological and cytological investigations as well as crossing experiments were carried out with the 5 species of theRanunculus alpestris group (R. alpestris L.,R. traunfellneri
Hoppe,R. bilobus
Bertol.,R. crenatus
Waldst. etKit.,R. magellensis
Ten.). A key to the species is presented; localities and distribution are given in addition to extensive diagnoses. Crossing experiments between the 5 taxa were successful (F1-F3 individuals, backcross types, tripeland quadrupelbastards); the morphology of the experimentally obtained F1-hybrids was mostly intermediate. All 5 species as well as all hybrids have a chromosome number of 2n = 16; there is no statistically significant difference between the karyotypes of the 5 taxa. According to the results of the morphological investigations and the crossing experiments we can distinguish 2 subunits of very closely related species: a)R. alpestris, R. traunfellneri, R. bilobus; b)R. crenatus, R. magellensis. The speciation within the group ofRanunculus alpestris is discussed. 相似文献

Morphological and cytological investigations as well as crossing experiments were carried out withRanunculus seguieri
Vill. and 4 species of theRanunculus alpestris L. group (R. alpestris L.,R. traunfellneri
Hoppe,R. bilobus
Bertol.,R. crenatus
Waldst. & Kit.). ForR. seguieri andR. alpestris, localities and distribution are given in addition to extensive diagnoses. A key to the species includes morphological characteristics and distribution data forR. traunfellneri, R. bilobus, andR. crenatus. New diagnostic characters are described. Crossing experiments betweenR. seguieri and the species of theR. alpestris group were unsuccessful. All 5 species have a chromosome number of 2n = 16, the record forR. bilobus is new. There is no statistically significant difference between the karyotypes ofR. seguieri andR. alpestris s. str. Nevertheless, according to morphological evidence and crossing experiments,R. seguieri is not closely related to theR. alpestris group. 相似文献

In 83 species of the familiesMonotropaceae, Apocynaceae, Oleaceae, Scrophulariaceae, Lentibulariaceae, Bignoniaceae, Martyniaceae, Myoporaceae, Verbenaceae, Lamiaceae, Campanulaceae, andLiliaceae, protein bodies in the cell nuclei have been found, in 68 of these species for the first time. On the basis of their structure in accordance with morphological characters the generaBurgsdorfia, Hesiodia, Olisia, andPhlomoides of theLamiaceae are accepted;Lamium is divided intoLamium, Lamiastrum andOrvala; two new combinations are established:Kickxia campyloceras (Rech. fil. &Esfandiari)Speta andEtornotus papilionaceus (Burm. in L.)Speta. Deviating shape or lack of protein bodies corroborate former taxonomic decisions, e.g. the transfer ofMonotropa toMonotropaceae or the separation ofGaleopsis andLadanum; Veronica schmidtiana should not be included inPseudolysimachion. Systematic affinities are discussed primarily withinScrophulariaceae because nuclear protein bodies have been studied already in many species of this family. ForCampanula patula two 2 x populations are reported.

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).

Cellulomonas cartalyticum was found to contain a peptidoglycan type different from that of the other species ofCellulomonas. The diamino acid is lysine instead of ornithine and the interpeptide bridge consists ofd-Asp-d-Ser. The same peptidoglycan type occurs inCorynebacterium manihot, Brevibacterium liticum andArthrobacter luteus. These non cellulolytic organisms are most likely not closely related withCellulomonas cartalyticum, as indicated by the very different G+C content of their DNA, although they formed a narrow cluster includingC. cartalyticum when numeric taxonomical methods were applied. 相似文献

In the lichen genusUsnea different species ofTrebouxia-phycobionts as well as different haustorial types are known. The isolated and cultivated phycobiont ofUsnea longissima
Ach. was studied by light- and electron microscopy and resembles in cytomorphological details the type ofTrebouxia impressa
Ahmad. In addition to simple wall-to-wall contacts between the symbiotic components also intraparietal (=intrawall-)haustoria could be observed as the normal interaction type.

(1) The ability to produce cephalodia is usually a genus-specific character in lichens. (2)Lecidea shushanii
Thoms., is a member of the genusTephromela, closely related toT. aglaea. It is not clear, whether or not the cephalodia of this taxon are true cephalodia or colonies of epiphytic cyanobacteria and whether or notLecidea shushanii is an independent species. (3)Lecidea dovrensis
Nyl., is, in contrast to the traditional concept, not conspecific withLecidea alpestris
Sommerf., but an earlier name forLecidea pallida
Th. Fr. (4)Lecidea dovrensis is described in some detail. Chemically the species is characterized by the presence of isousnic acid (previously unknown in lecideoid lichens). It is restricted to areas north of the 60th parallel with an oceanic climate. (5) In connection with the attempt to clarify the taxonomic relationships ofLecidea dovrensis, figures of ascus apical structures of the following species are given (marked by an asterisk are genera where we found discrepancies with published data):Austrolecia antarctica, Catillaria chalybeia, Lecidea alpestris, L. caesioatra, L. limosa, Lecidoma demissum, Koerberiella wimmeriana, Micarea assimilata, M. crassipes, M. melaenida, M. prasina, Pilophorus robustus, Placodiella olivacea, Placolecis opaca, Porpidia trullisata, Protoblastenia rupestris, Psilolechia lucida, Psorula rufonigra, Squamarina gypsacea, Xanthopsorella texana. (6) Among crustaceous lichens we find no groups related toLecidea dovrensis. We supportTimal's concept of including this species in the genusPilophorus. Pilophorus, as well asLecidea dovrensis is characterized by the same ascus type, by a similar structure of thallus, cephalodia, paraphyses, and ascocarp (although there is no pseudopodetium developed inLecidea dovrensis), and the presence of isousnic acid. In addition, both taxa are restricted to cool oceanic climates and non-calciferous substrates. The following combination is proposed:Pilophorus dovrensis (Nyl.)Timdal, Hertel & Rambold, comb. nova. (7) The species of theLecidea alpestris-group form an independent genus, probably near toAustrolecia
Hertel.

The biosystematics of theFestuca violacea group (F. rubra subsp.violacea sensuHackel) in the Eastern Alps is studied.F. picturata
Pils (=F. picta
Kit. exSchultes nonJ. F. Gmelin) is confirmed as diploid, whereas the chromosome numbers forF. nitida (diploid),F. puccinellii (hexaploid), andF. norica (diploid, tetraploid and hexaploid) are reported for the first time. Details of morphology, leaf anatomy, and epidermal structures now allow a better separation of these species; new maps illustrate their distribution. Karyological, chorological, morphological, and anatomical data form the basis for a discussion of the phylogeny of theF. violacea group and its position withinF. rubra s. latiss. 相似文献

InUmbilicaria hirsuta andU. grisea the so-called soredia originate from structured plectenchyma of the upper thallus layer (thus contrasting with true soredia, which are pushed off from unstructured medullar plectenchyma), and, therefore, are termed parasoredia. Both species have been regarded to comprise (in western Europe) forms with relatively large thalli and a pale lower surface; rhizinomorphs may be present (with varying density) or absent; propagation is not by parasoredia, but by flattened diaspores (schizidia s. l.) These forms are united here and described as a separate species:U. freyi (syn.U. hirsuta var.pyrenaica
Frey andU. grisea resp.murina f.subpapyria
Frey). So far, the species is known to occur from the western Alps through C. France to the Pyrenees, C. Spain and Italy including Sardinia.

A report is given on about 1000 specimens of 28 species ofPhorinae and their occurrence on 12 species ofUmbelliferae. Collections were made in a variety of habitats ranging from the German North Sea coast up to altitudes of 2500 m in the Western Alps. The morphology of the mouth-parts of the flies and their behaviour on the umbels are discussed briefly. No specific adaptations exist between Phorid flies and the visited umbels; their relationship is mutualistic. Climate and altitude have a greater influence on frequency and diversity of these visitors than the host-plants themselves. Visitors frequency and diversity increases with altitude.
