Two New Species of Pectis (Asteraceae: Tageteae) from South America

Pectis hassleri and P. pumila are new species, the former from the Gran Chaco area of Paraguay and the latter from southwestern Ecuador and northwestern Peru. Pectis hassleri differs from P. odorata by leaves that are glandular-punctate on the adaxial as well as the abaxial surfaces, by longer and w...

520 |a Pectis hassleri and P. pumila are new species, the former from the Gran Chaco area of Paraguay and the latter from southwestern Ecuador and northwestern Peru. Pectis hassleri differs from P. odorata by leaves that are glandular-punctate on the adaxial as well as the abaxial surfaces, by longer and wider ligules of the ray florets, and by ray pappi of awns and shorter bristles. Pectis pumila differs from the closely related P. arida by its wider leaves and by its sessile or subsessile capitula with campanulate involucres and obovate phyllaries. A hexaploid chromosome count of 2n = 36<sub>II</sub> is newly reported for P. pumila.
