Redescription and Distribution of Muilla Coronata (Liliaceae)

On the taxonomy of Puccinia coronata in Iran

In the present study, infra specific taxonomy of Puccinia coronata in Iran was studied. Based on morphological characters only, four P. coronata varieties were recognized in Iran. These are: P. coronata var. coronata, P. c. var. avenae, P. c. var. hordei and P. c. var. golestanica var. nov. Descriptions of the four varieties and their host range are provided. Several new hosts for aecial and te...

Tulipa cinnabarina subsp. toprakii (Liliaceae), a new subspecies from southwestern Anatolia

A new subpecies, Tulipa cinnabarina subsp. toprakii subsp. nov. (Liliaceae) from Turkey is described. Diagnostic characters, descriptions, detailed illustrations, geographical distribution, conservation status and ecological observations on the new taxon are provided. It is also compared with the closely related Tulipa cinnabarina subsp. cinnabarina.

The identity and distribution of Fiorinia phantasma (Cockerell & Robinson) (Hemiptera: Coccomorpha: Diaspididae), with a new synonym.

The morphologies of Fiorinia phantasma (Cockerell & Robinson) (Hemiptera: Coccomorpha: Diaspididae) and F. coronata Williams & Watson are reviewed, and the name F. coronata is placed as a junior synonym of the name F. phantasma syn. n. The known geographical distribution and host range of F. phantasma is documented and discussed. An identification key to 12 of the 16 species of Fiorinia known f...

Patterns of Virulence in Natural Populations of Puccinia coronata on Wild Oat in Israel and in Agricultural Populations on Cultivated Oat in the United States.

ABSTRACT Crown rust (Puccinia coronata) in indigenous populations of Avena sterilis has been cited as an example of stability of wild pathosystems that consist of natural mixtures of resistance and virulence. This study confirmed that virulence/avirulence polymorphisms in P. coronata on A. sterilis in Israel are highly diverse and that super races do not dominate. Isolates of P. coronata from I...
