“…It used to be called Leontochir ovallei Phil. but was placed in the Bomarea genus, rather than considering it to be a monotypic genus (Ravenna, 2000;Guarin, 2007). Phylogenetic analysis confirmed the placement of L. ovallei with the species of the genus Bomarea, leading to the renaming of L ovallei to B. ovallei (Aagesen and Sanso 2003;Guarin 2007).…”

However, Baeza et al (2012) revived the genus Leontochir as an independent genus, based on the higher asymmetry index of the L. ovallei karyotype compared to the Bomarea species karyotype.…”

“…Bomarea are popular and important flowering species because they are available in various colours. The genus Bomarea contains approximately 120 species and has a neotropical distribution from Mexico (24 °N) to Chile (40 °S) (Guarin, 2007;Chacón et al, 2012). In Chile, four species of the genus occur: Bomarea involucrosa (Herb.)…”

Bomarea ovallei (Phil.) Ravenna (2n=2x=18) is an endangered endemic species that inhabits only a small part of the coast of the Atacama region. We describe the structure, gene composition and phylogeny of the complete chloroplast sequence of this elusive species. The chloroplast genome consists of 155,018 bp, with typical quadripartite structures: a large single copy region (LSC) of 84,132 bp, a small single copy region (SSC) of 17,794 bp, and two inverted repeat regions (IRs) contain 26,546 bp. One hundred and thirty-four genes were identified out of which 84 coding genes, 8 rRNA, 38 tRNA and 4 pseudogenes. B. ovallei chloroplast resembles chloroplasts from seven species of the order Liliales in length and structure and is most similar to Bomarea edulis (BP=100). The average nucleotide variability (Pi) of 0.00254 between these two Bomarea species is moderate. Nine loci with increased variability were identified: rps16-trnQ, atpF, trnL, ndhC-trnV, rbcL, psbJ, rpl32-trnL, ndhD and ycf1. These loci could be used as DNA markers for classification and evaluation studies in Bomarea populations.

“…While many Bomarea are perennial twining vines, some species-mostly those that occur in alpine habitats above the tree line-are erect or suberect perennial herbs (Fig. 1; Alzate Guarín, 2005). Each above-ground stem senesces after flowering, and below-ground stems (rhizomes) and tuberous roots fuel the regrowth of subsequent above-ground structures (Tribble et al, 2021a,b).…”

Complex geological events such as mountain uplift affect how, when, and where species originate and go extinct, but measuring those effects is a longstanding challenge. The Andes arose through a series of complex geological processes over the past c. 100 million years, impacting the evolution of regional biota by creating barriers to gene flow, opening up new habitats, and changing local climate patterns. Bomarea are tropical geophytes with ranges extending from central Mexico to central Chile. Of the roughly 120 species of Bomarea, most are found in the Andes, and previous work has suggested that Bomarea diversified rapidly and recently, corresponding with the uplift of the Andes. While many Bomarea species occur over small, isolated ranges, Bomarea edulis occurs significantly beyond the ranges of any other Bomarea species (from central Mexico to northern Argentina) and is thought to have potentially humanmediated dispersal, due to its status as a pre-Columbian food plant. To untangle the potential drivers of diversification and biogeographic history in Bomarea, we used a target-capture approach to sequence nuclear loci of 174 accessions of 124 species, including 16 outgroup species from across the family (Alstroemeriaceae). We included 43 individuals of B. edulis from across its range to assess species monophyly and identify infraspecific phylogeographic patterns. We model biogeographic range evolution in Bomarea and test if Andean orogeny has impacted its diversification. We find that Bomarea originated in the central Andes during the mid-Miocene, then spread north, following the trajectory of major mountain uplift events. Most observed speciation events occurred during the Pleistocene, while global climate cooled and oscillated and the northern Andes achieved their current form. Furthermore, we find that Andean lineages diversified faster than their non-Andean relatives. These results demonstrate a clear macroevolutionary signal of Andean orogeny on this neotropical radiation.

Bomarea with 100–110 species represents the most diverse genus of Alstroemeriaceae. The genus is distributed from Chile to Mexico and comprises twining, prostrate or erect herbs with tuberous storage roots and pendant, showy flowers. Phylogenetic relationships and patterns of evolution within Bomarea have not yet been explored. Thus, neither the currently accepted classification nor patterns of morphological evolution have been evaluated. To resolve relationships within Bomarea, we sequenced three cpDNA regions (psbA-trnH, rpoB-trnC, matK) and the nrDNA ITS spacer regions (ITS 1 and ITS 2). MP and ML analyses of the combined data recover three major lineages in the genus and the composition of these clades is inconsistent with previous classifications based on morphology and biogeography. Patterns of evolution for three morphological characters were investigated by mapping them onto the phylogeny. The analyses indicate that the ancestor of Bomarea had compound umbels, a twining habit, and foliar indument. The phylogenetic analyses were unable to obtain high support, which suggests a relatively recent and rapid radiation of this genus.
