 Liebm.; this was by Fournier identified with Asp. varians Mett., which, however, is the 

 same as D. Schaffneri; Liebmann's type specimen consists of a single sterile leaf and belongs 

 to typical tetragona. P. tetragonum Liebm. is D. telragona var. 2 (see below).

Like typical tetragona in colour and pubescence but larger: pinnæ 3—3^3 cm 

 broad, incised only ^a 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. tetragona as formœ dubiœ 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. tetragona, and it is possible that
