Chromosome numbers of plants collected during Iter Mediterraneum V in Morocco

Abstract

The OPTIMA expeditions (Itinera Mediterranea) constitute a good opportunity for improving the karyological knowledge of taxa distributed in geographical areas little known in the Mediterranean region. The chromosome number of many gatherings collected during different expeditions was counted and published in several papers (Luque & Díaz Lifante 1991; Díaz Lifante & al. 1992; Vogt & Aparicio 1999; Vogt & Oberprieler 2012). During the fifth OPTIMA expedition in Morocco in June 1992 (Iter Mediterraneum V), 2366 gatherings were collected, belonging to 1418 taxa. Seeds from 143 gatherings were germinated and chromosome number counted. These specimens belong to 111 different taxa, 79 genera and 25 families
