Rich limestone Jurassic formations and huge water reservoir are natural characteristics of the Middle Atlas Chain in Morocco, which, therefore, offers geodiversity of karst geosystems. The geological, tectonic and hydro-geo-morphological nature of the history of Atlas orogeny has affected the eastern part of the Middle, ensuring the evolution of karst features on various sites of this zone. This study presents some touristic offers specific to the Middle Atlas, particularly in terms of genesis, structures, and functions that could develop and promote public tourism offers. It argues that this development depends on future geological funds identification and classification as Geosites. On the basis of the patrimonial process characterising the Middle Atlas, this study suggests the creation of a Geopark in the Middle Atlas, within the framework of the evaluation criteria of the UNESCO. The implementation of this suggestion would contribute to the socioeconomic development of this region of Morocco.

This study clarifies the taxonomic status of Anemone coronaria and segregates the species and A. coronaria infraspecific variants using morphological and morphometric analyses. Principal component analysis of the coronaria group was performed on 25 quantitative and qualitative characters, and morphometric analysis of the A. coronaria infraspecific variants was performed on 21 quantitative and qualitative characters. The results showed that the A. coronaria group clustered into four major groups: A. coronaria L., A. biflora DC, A. bucharica (Regel) Juz.ex Komarov, and a final group including A. eranthioides Regel and A. tschernjaewii Regel. The data on the A. coronaria infraspecific variants clustered into six groups: A. coronaria L. var. coronaria L., var. cyanea Ard., var. albiflora Rouy & Fouc., var. parviflora Regel, var. ventreana Ard., and var. rissoana Ard. © 2007 The Linnean Society of London, Botanical Journal of the Linnean Society, 2007, 153, 417–438.

The Flora of Syria, Palestine and Sinai, a pioneer Flora of the region, was published in 1896 by George Edward Post (1838–1909). Lesser known are his series of Diagnoses plantarum novarum orientalium, published in the Journal of the Linnean Society Botany, and 10 papers, Plantae Postianae, which appeared in Swiss journals from 1890 to 1900. A greatly expanded second edition of the Flora was prepared by John Edward Dinsmore and published in Beirut in 1932 and 1933. Post's plant collection is part of the Post Herbarium (BEI), with about 63 000 specimens, that has been well maintained, despite civil war and inadequate staffing. This work involves the identification of around 150 types in BEI and BM, and improvement of the accessibility of the specimens. © 2009 The Linnean Society of London, Botanical Journal of the Linnean Society, 2009, 159, 315–321.
