We inferred the phylogeny of Sambucus and Adoxa (Adoxoideae, Adoxaceae) based on nucleotide sequences of the internal transcribed spacer (TTS) region of nuclear ribosomal DNA, preliminary morphology, and a combination of the two data sets. Our morphological analysis implies that Adoxa is nested within Sambucus, based primarily on herbaceous habit and aspects of flower morphology However, there is strong support for the monophyly of Sambucus based on TTS sequences and in the combined analysis, implying that morphological similarities shared by Adorn and the two Australian species of Sambucus may have evolved independently The relatively small variation in ITS sequences within Sambucus makes the sequences easy to align, but results in some ambiguity due to a limited number of informative characters. Nevertheless, there are several well-supported clades within Sambucus. Species with paniculate inflorescences (sect. Botryosambucus) form a well-supported clade, within which the red-fruited
