 Title    Über die taxonomische Stellung der Hypocomidae (Ciliata) On the Taxonomie Position of Hypocomidae (Ciliata)  
 Abstract    Ultrastructural features of the ciliate Hypocoma acine­ tarum, an ectoparasite of the suctorian Ephelota, led to the conclusion that the Hypocomidae do not belong to the Cyrtophorida, as some authors suggested, but should be reunified with the Ancistrocomidae in the taxon Rhyncho-dida (Chatton et Lwoff).

 Title    Occurrence of Vesicular-Arbuscular Mycorrhizal Fungi in Alberta, Canada  
 Abstract    Three V A mycorrhizal fungal species were isolated from soils in Alberta, Canada and ex­ amined by scanning electron microscopy and energy-dispersive X-ray microanalysis. Mature spores of Glom us aggregatum developed an outer hyaline wall which contained lower levels of calcium than the middle wall. Examination of G. pansihalos spores revealed a lower level of calcium in the outer evanescent wall as compared to the ornamented wall. When spores of Entrophospora infrequens were examined, the wall of the vesicle was found to contain simi­ lar levels of calcium as the ornamented wall of the spore. The significance of the results con­ cerning the presence of calcium in mycorrhizal spore walls is discussed, as is the occurrence of the mycorrhizal species.

 Title    Fatty Acid Composition of Some Ranunculaceae Seed Oils  
 Abstract    The fatty acid composition of seed oils of eight Ranunculaceae was determinated in order to characterize new sources of gamma-linolenic acid. Fatty acids were identified as fatty acid methyl esters (FAME) by capillary gas-liquid chromatography (GC) and capillary GC-Fourier transform infrared spectroscopy (FTIR). For trienic FAME the use of a cyanopropyl-polysiloxane stationary phase (CP-Sil 88) allowed the separation with high resolution of methyl ester of columbinic acid (trans-5,c/s-9,ds-12 18:3) and gamma-linolenic acid (cis-6,cis-9,cis-12 18:3). The results confirmed the presence of columbinic acid in Thalictrum seed oils, and that of gamma-linolenic acid in A n e m o n e and related species seed oils. The taxonomic subdivision of Ranunculaceae into sub-families and tribes, which resulted from morphological considera­ tions, did not account for the above results.
