| Whilst studying the material of the genus Securidaca for the “Flora of Suriname”, I found it in most cases extremely difficult or even impossible to identify the species. The original descriptions are, as a rule, very short, and they have been based for a good deal on incomplete material: mature fruits, for instance, are often missing. Hence it is not surprising that on quite a number of species the opinions of taxonomists disagree. Accordingly on the one hand we may find in the various collections the most different species lumped together under the same name, while on the other hand one and the same species may appear under several names. A study of the type specimens therefore, was obviously very desirable. I am indebted to the “VAN EEDEN FONDS” for... |

| During the manufacture of paper living organisms may be the cause of undesirable slime deposits (consisting of bacterial colonies and fungus hyphae) in the machines. An extensive literature on this subject has accumulated and many of these fungus species have been isolated and described. The aim of Mrs. Wang's investigation is not only to determine the species and their frequency in pulp and paper mills in New York State, but also to provide a compendium describing and illustrating the fungus species in order to facilitate their recognition by workers in this field of microbiology and mycology. Following a “Review of Literature” and a chapter on “Materials and Methods” there is a chapter entitled “Results and discussion”. The bulk of the contents, however,... |
