ABSTRACT: A study was made of grasslands in olive
groves with a high frequency of Hordeum
leporinum Link, Chrysanthemum
coronarium L., Malva neglecta Wallr., Aegilops geniculata Roth and Dasypyrum villosum (L.) Borbas,
initially included in the alliance Hordeion
leporini Br.-Bl. in Br.-Bl., Gajewski, Wraber & Walas 1936 corr. O.
Bolós 1962, and sub-alliance Malvenion
neglectae Gutte 1966. The study was carried out in the western
Mediterranean (Spain, Italy, Portugal and northern Morocco). The soil and
phytosociological treatment of the samples contributes information for new
plant communities. In the study of plant communities, the indices of degree of
presence are adapted to those of Van der Maarel. The new alliance Securigero securidacae-Dasypyrion villosi is proposed for the sub-Mediterranean and Euro-Siberian territories, with the
new communities Securigero
securidacae-Dasypyretum villosi and Convolvulo
elegantissimi-Aegilopetum geniculatae. This last community, due to its
richness in Aegilops geniculata Roth,
could be included in the alliance Taeniathero-Aegilopion
geniculatae Rivas-Martínez & Izco 1977; however, the soil and
statistical analyses reveal that it should remain part of the alliance Securigero securidacae-Dasypyrion villosi. The soil and floristic study of Hordeion
leporini and Malvenion neglectae allows
us to describe the new sub-alliance Resedo
albae-Chrysanthemenion coronarii, subordinated to Malvion neglectae (Gutte 1966) status novo.
