same as D. Schaffneri; LIEBMANN's type specimen consists of a single sterile leaf and belongs 
to typical fetragona. P. tetragonum Liebm. is D. tetragona vay. 2 (see below).

Like typical fetragona in colour and pubescence but larger: pinnz 3—3'/» cm 
broad, incised only 4/2 of the way down, and 2—3 pairs of veins anastomosing. 
Not unlike D. megalodus but without stellate hairs beneath.

In Central-America a long series of forms is to be found, which I dare not 
refer to any of the accepted species. As most of these forms are known only from 
a single or a few specimens, which rarely are fully identical, I prefer to place them 
under D. fetragona as forme dubic instead of describing them as new species. In 
these forms the most important characters of the species tetragona, obliterata, nica- 
raguensis and tristis are combined. A special mark of the majority of these forms 
is that the basal veins do not anastomose but are connivent to sinus, although the 
leaves in other respects very much resemble D. fetragona, and it is possible that
