Iran supports a great share of exotic and/or endemic plant genera and species. The genus Fritillaria(Liliaceae) is a precious part of this botanical richness with 19 species, of which 10 are endemic to the country. However, signs are mounting that the country is truly at a crossroads when it comes to preservation of this national wealth. In this regard, an effective conservation strategy should thoroughly consider the classification of Fritillaria, as conservation practices are compromised by knowledge gaps in systematics and taxonomy. As published studies on Fritillaria in Iran have been sporadic and limited in scope, the aim of this review is to provide information necessary to help bridge these information *** objective is to facilitate increased understanding of the geographic, taxonomic, cytogenetic and phylogenetic status of Iranian Fritilloria, which is vital to meeting the goal of sustainable conservation of the genus in Iran and neighboring areas.

There had been no standardized rules for citing ethical Kampo products used in clinical trials in journal articles. Although the name of a Kampo manufacturer was described in 77.9% of research articles, the name and ratios of crude drug components of Kampo formulas were not described in 77.5% of these papers. Considering the importance of proper characterization of interventions in the Consolidated Standards of Reporting Trials （CONSORT） checklist, we hereby propose the use of the Standards of Reporting Kampo Products （STORK） website, http：//***/stork, as a reference for Kampo products. This will provide an official source on the internet for verified information on individual Kampo formulations for citation purposes in clinical research articles.
