The OTU's of M. vulgare are discriminated through various attributes, besides four biotypes within M. alysson. Throughout the usage of RAPD analysis, both M. vulgare and OTU 31 of M. alysson are segregated together in the dendrogram. Therefore, the present study recommended the allocation of OTU 31 of M. alysson at higher rank than biotype. In the intervening time, Marrubium species and its biotypes must be listed as endangered taxa and efforts must be intensified for their protection.

The study aimed to revise the classification and identification of Launaea species in Egypt. The study also aimed to assess the inter- and intraspecific variation among taxa using macro- and micromorphological characters. Numerical analysis was carried out on 156 specimens, which were collected from 63 sites in Egypt. The results revealed that L. arabica, L. capitata, L. intybacea and L. spinosa were significantly (p-value < 2.2 × 10−16 ***) discriminated from the other species at a high dissimilarity level. Launaea acanthodes was correctly identified as Lactuca orientalis. The study supported the inclusion of L. intybacea, L. massauensis and L. nudicaulis within section Microrhynchus, the separation of L. angustifolia and L. arabica in two distinct species. Two biotypes of L. nudicaulis were morphologically differentiated. Launaea fragilis subsp. fragilis showed considerable plasticity and variability ...
