FIGURE 1. Dennstaedtia cicutaria. A. Geographical distribution of the species in Argentina (● = location of the studied populations). B. Rhizome unbranched, pubescent and petioles with petiolar buds, bearing roots at the base. C. Pinnule linearlanceolate, petiolate. D. Segments of basal pinnula, pinnatisect, oblog-lanceolated, showing sori born in sinuses. E. Detail of pinna showing costule pubescent abaxially, without perpendicular herbaceous wings on the upper surface. F. Spore with MEB, polar proximal view. Ornamentation verrucate, the verrucae uniform, rounded, ornamented with rodlets. G–I. Spores with MO in polar proximal view (G), polar distal view (H) and ecuatorial view (I). The spores are dark-brown and the verrucae are evident. Scale bars: B and E = 2 cm; C = 3 cm; D = 1 cm; F–I = 10 µm. B–I from Rodriguez et al. 694 (LP).
