Abstract

Previous studies have shown Homalomena Scott as usually defined to be polyphyletic, with Neotropical species phylogenetically distinct from Asian species. In this study we include 18 more accessions of Neotropical taxa, and analyse in total 123 accessions representing 115 accessions of Homalomeneae and Philodendreae for the nuclear ITS region together with 42 accessions for the plastid matK region. Results support resurrection of the genus Adelonema Schott for all Neotropical species currently assigned to Homalomena. Adelonema is a wholly Neotropical genus of sixteen species. Twelve new combinations are made, along with the description of four new species. Adelonema is divided into two sections: section Adelonema and section Curmeria based on morphologically supported molecular results. Adelonema is distinguished by an hypogeal rhizome, vegetative tissues smelling of anise (when crushed), an extensively sheathing, sometimes prickly petiole, chartaceous often variegated leaf blade, a spadix either obliquely inserted on the spathe/peduncle (sect. Adelonema), or stipitate (sect. Curmeria), ovaries with 2-4- pluriovulate locules, and anatropous ovules on a central placenta.
