HERNANDEZ, Marcelo; GIULIANO, Daniel  e  FREIRE, Susana. Micromorphological analysis of Senecio subseries Polyphylli (Senecioneae, Asteraceae). Lilloa [online]. 2018, vol.55, n.2, pp.47-66. ISSN 0075-9481.  http://dx.doi.org/10.30550/2018.55.2/5.

A micromorphological study of the species of Senecio subseries Polyphylli is presented. Vegetative (leaf trichomes) and reproductive characters (phyllary and achene trichomes; middle vein of the tubulose corolla teeth; anther collars, anther bases, and connectival appendages; pollen; style branches; achenes) are analyzed. A key based on microcharacters for the identification of the species is presented.
