Abstract
A phylogenetic analysis of the genus Homalomena (Araceae: Homalomeneae) based on the nuclear ITS region is presented. Eighty nine taxa are included, representing all Asian Supergroups (SG): Homalomena, Chamaecladon, Punctulata and Cyrtocladon, several Neotropical species currently assigned to Homalomena, and Philodendron. Asian Homalomena is well supported as monophyletic and excludes Neotropical Homalomena. The Homalomena and Chamaecladon SGs are well supported. Cyrtocladon SG is monophyletic after transfer of the Insignis Complex and Havilandii Complex into the Punctulata SG. A reduced phylogeny of 20 accessions representing 15 taxa was used for subsequent morphological and chemical-marker optimization. Chemical markers identified from LCMS profiling provided an independent set of markers that further support the separation of Neotropical Homalomena from the Asian taxa. Three chemical markers at Rt 2.55 mins, 2.69 mins and 2.90 mins are shared among the majority of taxa sampled. However, Neotropical Homalomena show two additional peaks at Rt 3.25 mins and 3.54 mins. Five chemical markers support the Cyrtocladon SG excepting Homalomena vivens. A chemical marker at Rt 3.60 mins is plesiomorphic for the Chamaecladon, Homalomena and Punctulata SGs. A chemical marker at Rt 2.80 mins is apomorphic for the Chamaecladon SG, with a separate gain in H. punctulata. Overall this study supports the supergroups proposed in previous papers and permits refining of the Cyrtocladon and Punctulata SGs.
