Abstract
Pectis hassleri and P. pumila are new species, the former from the Gran Chaco area of Paraguay and the latter from southwester Encuador and northwestern Peru. Pectis hassleri differs from P. odorata by leaves that are glandular-punctaoten 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 campanulatein volucresa nd obovatep hyllaries.A hexaploid chromosome count of 2n = 361 is newly reported for P. pumila.
