Several fern remains are described from the para-autochthonous early late Ladinian flora of the Monte Agnello (Dolomites,
N-Italy). The plants are preserved in subaerially deposited pyroclastic layers. Some ferns, known already from the
Anisian and Ladinian of this area, are confirmed (Neuropteridium elegans), but several taxa are described for the first
time (Phlebopteris fiemmensis sp. nov., Cladophlebis ladinica sp. nov., Chiropteris monteagnellii sp. nov.). Cladophlebis
sp. and some indeterminable fern remains cannot yet be assigned to any family. Phlebopteris fiemmensis is now the
oldest formally established species in the genus. The fern family Dipteridaceae (Thaumatopteris sp. and some fragments
probably belonging to the Dipteridaceae because of their venation) has not been recorded previously from European
sediments as old as the Ladinian. Although stratigraphically attributed to the late Ladinian, the flora is markedly distinct
from other Ladinian floras of the Dolomites and the Germanic Basin. The flora from Monte Agnello shows a higher diversity
in ferns than coeval floras from this area although characteristic elements of the Ladinian of the Dolomites such as
Anomopteris and Gordonopteris are missing. The new flora misses also the Marattiales (e.g., Danaeopsis, Asterotheca)
and other elements such as Sphenopteris schoenleiniana, typical for the Ladinian of the Germanic Basin.
