Pascalia glauca (Wedelia glauca) is a member of the Heliantheae-Ecliptinae (Asteraceae) native to South America, which however has become naturalized and invasive around the globe. After studying the protologue and the historical materials kept at Real Jardín Botánico de Madrid (Spain), both a lectotype and an epitype are designated for P. glauca....

... and sent to Madrid were planted and flowered in 1796(cfr. Muñoz Garmendia 1989, and most likely one of them was the material later used by Gómez-Ortega, the director of MA between 1771 and 1801 (cfr. Colmeiro 1858), for describing his new species. Living plants of P. glauca are still found on the flowerbeds of Real Jardín Botánico de Madrid (Fig. 3), most probably being descendants ('clonotypes') from those first introduced ...

... that illustration is to be selected as the obligate lectotype (Art. 9.2, ICN), but we exclude the figure numbered 12 on the left upper corner (detail of a lower leaf), since it is atypical and could correspond to a different taxon of Wedelia or Sphagneticola Hoffmann (1900: 36) which could have been growing together with P. glauca at MA (see Fig. 3A for details of typical lower leaves of the latter ...

... Joining several successive gatherings of the same type plant in a single voucher appears to be a common practice in the 19 th century in MA, perhaps due to the scarcity of paper and/or space in the herbarium. This fact sometimes makes difficult identification of original material of plants collected in the Spanish expeditions around the New World (see, for instance, Crespo & Pena-Martín 2014). ...
In a recent paper, the name Ximenesia encelioides was lectotypified on material conserved at MA. However, the selected “lectotype” includes several fragments collected at three different times, and that herbarium sheet is therefore to be considered to contain three different specimens as defined in Art. 8.2 of the International Code of Nomenclature of algae, fungi and plants. This fact makes that “lectotype” invalid since contrary to Art. 8.1, and hence the previous lectotypification is to be disregarded. Accordingly, a new lectotype is designated for that name, currently accepted as Verbesina encelioides.

Abstract Pascalia glauca is an invasive and toxic perineal plant native to southern South America. A small populations of plant were recorded for first time in Al-Diwanyia province / Iraq and they was responsible for mortality in grazing cattle. The authors recommend an urgent action by the authorities to control growing this toxic plant before it spreads uncontrollably, as well as a warning notification should be mentioned for the breeder to prevent livestock's mortality. ____________________________________________________________________________________ To Cite this article: Hayder M.
