Biometrische Untersuchungen an Populationen vonOphrys cornuta,O. holosericea und ihren Hybriden (Orchidaceae)

Population variability ofOphrys holosericea (Burm. f.)Greut. subsp.holosericea (=O. fuciflora Crantz subsp.fuciflora) from near Vienna (Austria), and of subsp.maxima (Fleischm.)Greut. andO. cornuta Steven with intermediates from the Dalmatian island Hvar (Yugoslavia) was analysed and illustrated by scatter diagrams. A hybrid origin of these intermediates is suggested. Aspects of hybridization betweenO. holosericea agg. andO. scolopax agg. are discussed.

     

Cynoglossopsis somaliensis,sp. nov., und die GattungCynoglossopsis (Boraginaceae)

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.

     

Die Mureintypen in der Gattung Cellulomonas Bergey et al.

Zusammenfassung Die Untersuchung der Mureinstruktur und der Polysaccharidzusammensetzung der Zellwände von sieben Arten der Gattung Cellulomonas ergab, daß alle Arten mit Ausnahme von C. flavigena Murein vom L-Orn-D-Glu-Type enthalten. Bei C. flavigena ist die D-Glutaminsäure der Interpeptidbrücke durch D-Asparaginsäure ersetzt. Die Polysaccharidzusammensetzung ist wesentlich variabler und bei den meisten Arten voneinander verschieden.Die Einheitlichkeit der Mureinstruktur einerseits und die Verschiedenheit des Mureintyps von allen anderen coryneformen Bakterien andererseits spricht für die Berechtigung, die cellulolytischen coryneformen Bakterien in einer eigenen Gattung zusammenzufassen.

The murein types in the genus Cellulomonas Bergey et al.

Summary The investigation of the murein(peptidoglycan)structure of 6 species of Cellulomonas showed, that all species besides C. flavigena contain the L-Orn-D-Glu-type. In C. flavigena D-glutamic acid of the interpeptide bridge is replaced by D-aspartic acid. The composition of the polysaccharide of the cell wall is much more variable and differs in most species.The observation that the murein type is uniform within the genus but quite different from the murein types found in other coryneform organisms justifies the unification of the cellulolytic coryneform bacteria in the genus Cellulomonas.

Arabis pumila Jacq. subsp.pumila (4x) und subsp.stettulata (Bertol.)Nyman (2x) als chromosomal und morphologisch verschiedene Taxa

Zusammenfassung Arabis pumila Jacq. subsp.stettulata (Bebtol.)Nyman (2n=16) unterscheidet sich von subsp.pumila (2n=32) außer durch eine geringere Zahl von Stengelblättern und Blüten vor allem durch das Vorherrschen von (3-)4(-5)spaltigen Haaren im Indument insbesondere der Oberseite und des Randes der Grundblätter; bei subsp.pumila überwiegen dort 2spaltige und einfache Haare. Die beiden Unterarten wachsen in den Ostalpen etwa im gleichen Verbreitungsgebiet. Die Entstehung der subsp.pumila und die Nomenklatur beider Taxa werden diskutiert.

Chromosomal and morphological differences betweenArabis pumila Jacq. subsp.pumila (4x) and subsp.stellulata (Bertol.)Nyman (2x)

Summary Arabis pumila Jacq. subsp.stellulata (Bertol.)Nyman (2n=16) is dinstinct from subsp.pumila (2n=32) by the following characters: subsp.stellulata reveals fewer cauline leaves and flowers than subsp.pumila, in the main the former is characterized by predominating (3-)4(-5)-fid hairs especially on the upper surface and margin of the basal leaves, the latter by mainly 2-fid and unbranched hairs. In the Eastern Alps both the subspecies occur in about the same area. The origin of subsp.pumila and the nomenclature of both taxa are discussed.

     

A proposito del riferimento di Emericella variecolor Berk,et Br. ad Aspergillus effettuato da Thom e Raper

Riassunto Si critica la combinazione Aspergillus variecolor creata da Thom e Raper per l'Emericella variecolor sulla base dell'identità della forma conidica (Aspergillus), senza tenere in nessun conto la notevole diversità di morfologia delle ascospore di E. variecolor rispetto a quelle di Aspergillus nidulans, nel quale gruppo Thom e Raper vorrebbero porre E. variecolor.

Summary The new combination Aspergillus variecolor for Emericella variecolor, made by Thom and Raper, on the base of identity of the conidic form, and without taking in consideration the different morphology of the ascospores of E. variecolor in comparison with those of Aspergillus nidulans (a group including also E. variecolor, according the above quoted students) is criticized.

---

Zusammenfassung Man kritisiert die Kombination des Aspergillus variecolor, die von Thom und Raper durch Emericella variecolor auf Basis der Identität der konidischen Form (Aspergillus) geschaffen wurde, ohne jegliche Berücksichtigung der bemerkenswerten Verschiedenheit der Morphologie zwischen den Askosporen des E. variecolor und denen des Aspergillus nidulans (in die letzte Gruppe wollen Thom und Raper den E. variecolor einreihen).

---

Sumario La combinaoión Aspergillus variecolor, creada por Thom y Raper por Emericella variecolor en base a la identidad de la forma conidica (Aspergillus), sin tener en cuenta la notable diferencia entre la morfologia de las ascosporas de E. variecolor frente aquellas de Aspergillus nidulans (en el cual grupo los cienciados americanos quieren situar E. variecolor) está considerata como criticable.

Coremiella cuboidea (Sacc. et Ell.) Cif. et Car. n. comb. isolata da feci umane

Riassunto Sono studiati nelle loro caratteristiche morfo-culturali e biologiche quattro ceppi omogenei diCoremiella isolati da feci umane. Questo genera è simile aGeotrichum ma oltre a cellule miceliche clamidosporo-simili presenta formazione apicali miceliche di tipo coremioide reptante.L'artrosporulazione è un processo endogeno come inGeotrichum, e come inGeorichum si hanno artrospore clamidosporioidi fertili opache e artrospore usuali non fertili e jaline, ma meno differenziate.I ceppi vengono riferiti aC. ulmariae e le caratteristiche vengono paragonate anche con le culture su legno diSpirea ulmaria.Il primo esemplare diCoremiella è stato pubblicato comeOospora cuboidea Sacc. etEll. come è stato accertato studiando l'esemplare autentico diEllis.In conclusione il genereCoremiella Bub. etKrieg. è stato emendato ed è stata creata la combinazioneC. cuboidea (Sacc. etEll.).

Summary Four homogeneous strains ofCoremiella from human feces were studied from morpho-cultural and biological standpoint. This genus is likeGeotrichum, but in addition to some mycelial, chlamydospore-like cells, coremioid mycelial, reptant strands are formed.The arthrosporulation is an endogeneous process, and, likeGeotrichum, there are usual hyaline and duller chlamydosporioid, fertile arthrospores, but less differentiated.The strains are referred toC. ulmariae, and the characteristics were compared also on timber and woody European Meadowsweet cultures. But the first binomial ofCoremiella has been published asOospora cuboidea Ell. etSacc., as ascertained by the study of the authenticEllis specimen.In conclusion, the genusCoremiella Bub. etKrieg. has been emended, and the combinationC. cuboidea (Sacc. etEll.) established.

Heteromerikarpie und Fruchtpolymorphismus beiMicroparacaryum,gen. nov., (Boraginaceae)

Microparacaryum (M. Pop. exH. Riedl)Hilger & Podlech is described as a new genus of theBoraginaceae-Cynoglosseae. It comprises the annual species hitherto included inParacaryum (DC.)Boiss. andMattiastrum (Boiss.)Brand. Distribution maps are given for all 3 genera.Microparacaryum consists of two species,M. salsum (Boiss.)Hilger & Podlech (M. s.) andM. intermedium (Fresen.)Hilger & Podlech (M. i.). ParticularlyM. i. is a very variable species, and most of the species formerly recognized belong here. Scattered all over the range of the genus, plants occur with nutlets exhibiting flat or incurved marginal wings, often in mixed populations. This fruit polymorphism is taxonomically treated by recognizing formae. In addition, the following new infraspecific taxa and combinations are described:M. i. var.intermedium formaparacaryoides Hilger & Podlech,M. i. var.stellatum (H. Riedl)Hilger & Podlech,M. i. var.stellatum formamattiastroides Hilger & Podlech,M. s. formamattiastroides Hilger & Podlech.
