Notes on Algal Flora of Manchoukuo. I

Some notes on taxonomy and diversity of Onosma with emphasis on important evidence and complex groups in Flora Iranica

Onosma L. as a rich taxa in Boraginaceae including about 150–180 species, centered mainly in Irano-Turanian region. The genus faced with several systematic complexities lead to many identification problems as well as morphological polymorphism. Several authors have used setae characteristics in Onosma as the most important diagnostic evidence in delimitation and classification of species in add...

These notes have the status of "Letters written to myself": I wrote them down because, without doing so, I found myself repeating the same arguments over and over again. When reading what I had written, I was not always too satisfied. For one thing, I felt that they suffered from a marked verbosity. Yet I do not try to condense them (now), firstly because that would introduce another delay and ...

Prasiola calophylla and Closterium navicula, two new records of algal flora from Iran

Two new algal species, namely, Prasiola calophylla (Prasiolaceae), and Closterium navicula (Closteriaceae) were collected from west coasts of the Caspian sea (Mazandaran province, N Iran), and runoff in south Tehran, respectively. Both the species were analyzed on the bases of morphological and anatomical characters and were determined using identification keys and interspecific comparison. Pra...

Cylindrospermum voukii and Wollea saccata, new records for algal flora of Iran

Cyanobacteria represent a small taxonomic group of photosynthetic prokaryotes which some of them are capable of N2 fixation and also possess a tremendous potential for producing a wide range of secondary metabolites. It has been suggested that, some of these microorganisms, especially heterocystous cyanobacteria, assist higher plant growth by supplying growth stimulating substances. During a fl...
