Danaea cuspidata clade

This moderately supported (BP = 77) clade is a mixture of large and small plants, translucent and thick laminae and distributions from Mexico to Bolivia and the Guianas (including Danaea ypori , the only species in D. subg. Holodanaea with a Guianan distribution) but no species from the Caribbean islands.

Both Danaea cuspidata (from Mexico) and the newly described D. andina (from Ecuador) formed strongly supported clades within the D. cuspidata clade, confirming their distinctness from D. moritziana . However, their positions within the D. cuspidata clade varied between analyses done with different alignments and was not well resolved in any of them. In general, the species in this clade were supported by the phylogenetic results, although most of them had too few samples for their coherence to be properly tested. The morphologically relatively similar D. imbricata and D. trichomanoides were resolved to different subclades, supporting their recognition as distinct species.
