A new combination in Roldana (Compositae, Senecioneae)
Phytotaxa, 2016Working on the Ecuadorian Senecio species, I focused my attention on Senecio hamamelidifolius Kunth in Humboldt et al. (1818: 140), a poorly known species that Nordenstam (1999) pointed out to be doubtfully described from Ecuador as indicated with a question mark in the protologue. Further research on this matter led me to realize that the same species

Identification of the Genomic Complements of Emilia praetermissa (Senecioneae-Compositae)
American Journal of Botany, 1973Statistical tests show that the ten large chromosomes of Emilia praetermissa Milne‐Redhead were derived from E. coccinea (Sims) G. Don while the remaining ten small chromosomes of E. praetermissa were derived from E. sonchifolia (L.) DC. It is shown too that mean length of chromosomes is smaller and more variable among the cells of diploids (species ...
