Ornitogalum macrum Speta, a new species, is described from the Çakilli-Pass on the road from Akseki to the Bey sehir-Lake in Turkey. It is characterized by its tenderness. Roots turning yellow and concrescente leaves of the bulb speak in favour of a membership to theO. umbellatum group. But the late appearance of the foliage leaves in spring and the lack of ridges on the gynoeceum have hitherto never been found in this connection. There is however an indisputable similarity as to characteristics of theO. undulatum group. The chromosome number is 2n=54. The interphase nuclei are chromomeric.  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).

Zusammenfassung Die Verfasser versuchen an Hand eigener Untersuchungen und anderer im türkischen Raum durchgeführten Untersuchungen einen Überblick über die hier vorkommenden Pilzerkrankungen und ihre Erreger zu gewinnen.Im Gegensatz zu älteren Untersuchungen wird ein Vordringen der Epidermophytien, besonders der Epidermophytia palmaris et plantaris auch bei der Landbevölkerung festgestellt und die Gründe dafür werden dargelegt. Der Häufigkeit nach konnten folgende Pilzstämme als Erreger der Epidermophytien festgestellt werden:Epidermophyton floccosum (Harz)Langeron etMilochevitch,Epidermophyton interdigitale Priestley undTrichophyton rubrum (Castellani)Sabouraud.Bei den Kopfpilzerkrankungen wurde als hauptsächlichster Erreger der Trichophytia superficialis et profunda capillitii dasTrichophyton violaceum Bloch gefunden. Der Erreger des Favus in unserem Krankenmaterial ist dasTrichophyton Schönleini. Die Mikrosporie tritt an Häufigkeit gegenüber den vorgenannten Kopfpilzerkrankungen zurück, im Ankaraner Material wurde als Erreger nur dasMicrosporon canis Bodin gefunden. Bei der Trichophytie des übrigen Körpers und der Barttrichophytie steht als Erreger ebenfalls dasTrichophyton violaceum Bloch an der Spitze. Bei Onychomykosen sind die häufigsten Erreger dasEpidermophyton floccosum (Harz)Langeron etMilochevitch und dasTrichophyton interdigitale Priestley, andere Erreger treten an Häufigkeit diesen gegenüber zurück.Von saprophytären Pilzerkrankungen kommt die Pityriasis versicolor häufiger vor, Erythrasma und Piedra sind sehr selten.Es wird ferner über vereinzelte Fälle von oberflächlichen und tiefen Blastomykosen berichtet, bei denen als Erreger dieCandida albicans und derCryptococcus neoformans (Sanfelice)Vuillemin gefunden wurden.Von seltenen tiefen Mykosen wurden aus der Türkei vereinzelte Fälle von Histoplasmose (Histoplasma capsulatum), Sporotrichose (Sporotrichum Schenckii), Rhinosporidiosis (Rhinosporidium Seeberi), Madura-Fuß und Aktinomykose sowie Aspergillose (Aspergillus fumigatus Fresenius) mitgeteilt.
Summary The authors undertook the task, on hand of their own investigations and by reviewing the Turkisch literature, to give a picture about the occurrence of fungus diseases and their causative agents.In contradistinction with older investigations an increase of Epidermophytia, particularly, that of the palms and the soles, have been noted also in the rural population and their reasons are discussed. According to their frequency the following fungus species as causative agent of Epidermophytia were established (E. floccosum (Harz)Langeron etMilochevitch,E. interdigitale Priestley andTr. rubrum (Castellani)Sabouraud.In tinea capitis (superficialis et profunda) as the main causative speciesTr. violaceum Bloch was established. In favus onlyTr. Schönleini was found. Tinea microsporina, in comparison, is far less in the material at Ankara, with the only causative agent ofM. caninum Bodin. In cases of trichophytia corporis et barbae the prevalent agent was also theTr. violaceum. In onychomycosisE. floccosum andTr. interdigitale were prevailing.Among the saprophytosis Pityriasis versicolor was more frequent, while Erythrasma and Piedra were extremely rare.The review also refers to superficial and deep seated blastomycoses in whichC. albicans andCryptococcus neoformans (Sanfelice)Vuillemin, respectively, were found.Among rare mycoses there were found in the Turkey scattered cases of histoplasmosis (H. capsulatum), sporotrichosis (Sp. schenckii), rhinosporidiosis (Rhinosporidium seeberi), madura foot, actinomycosis as well as aspergillosis (A. fumigatus Fres.).

On the basis of the present concept of theChlorophyta, a new class, theChlamydophyceae, is established and described. It includes allVolvocales with cell walls, theTetrasporales and thoseChlorococcales with zoospores of theChlamydomonas-type. The diagnostic features of theChlamydophyceae are as follows. Both, flagellates and zoospores have a cell wall with specific ultrastructure which lacks cellulose. The cell wall of the gametes is thrown off before or during fusion. Protoplast divisions are multiple (schizogonic); binary (schizotomic) fissions do not occur. Sporangia and gametangia are formed already on the monadoid level. In asexual resting stages the old cell wall is incorporated into the cyst wall. The polarized structure of theChlamydomonas-like flagellate is ± maintained in non-motile stages. Contractile vacuoles occur in freshwater species, and only sometimes disappear in adult and old non-motile cells; proper central vacuoles are lacking.—From the morphological point of viewChlamydophyceae can be derived from stages in the life cycle ofChlamydomonas. Relationships with theChlorophyceae s. str. and the other Green Algae are discussed.

Zusammenfassung Abschlie\end möge gesagt sein, da\ die Reflektographie neben dem Vorteil des leichten photographischen Festhaltens der Reflexbilder vor allem deshalb eine ausgezeichnete Methode der Darstellung von GewebsoberflÄchen ist, weil sie auf eine Ähnlichkeit im Sinne einer Abbildung verzichtet und an deren Stelle die einer OberflÄche adÄquate Darstellung setzt, die Reflexprojektion. Bei dieser ist praktisch keine Rede von einer unteren Auflösungsgrenze und die Feinheit der Darstellung ist lediglich abhÄngig von der Grö\e der Lochblende bezw. vom Querschnitt des verwendeten Büschels, weswegen auch die Kleinheit der zu untersuchenden Objekte praktisch keine untere Grenze hat.  相似文献

Four new species ofJacaranda have been found in the coastal mountain-ranges of SE-Brazil where they occupy characteristic ecological positions.J. montana andJ. subalpina are related toJ. puberula agg.,J. pulcherrima shows affinities toJ. ulei but also toJ. subalpina. J. crassifolia is very distinct and possibly related toJ. obovata.

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.
