Abstract

Three new species ofLachemilla(Rosaceae), two from Colombia and one from Peru, are described and illustrated.Lachemillarothmalerianais characterized by its stout stems, sericeous-villous indumentum, and wide ascending sheaths with trilobate lateral lobes.Lachemillaargenteapresents a unique combination of tripartite basal leaves with an adaxial silvery villous indumentum, and decumbent branches with verticillate lobed sheaths. Finally,Lachemillacyaneahas distinctly basal reniform leaves with a blue-green color and hirsute pubescence. Phylogenetic analyses of the nuclear ribosomal cistron and multiple regions of the plastid genome revealed the allopolyploid origin of the three new taxa.
