“…Often minimal genetic changes are required to produce morphological variation, and these changes can be easily observed and quantified for use in phylogenetic inferences. Although pollen characters alone do not appear to correlate clearly with the current subgeneric classification of Bomarea (Hofreiter & Tillich 2002), it would be useful to develop a morphological and anatomical data set for future systematic analyses of Bomarea (Hofreiter & Lyshede 2006). The infrageneric classification of Bomarea can be reliably achieved by combined analyses of morphological, palynological, and molecular data from larger numbers of specimens of all species.…”

“…2). The exceptionally large pollen of B. foertheriana might be an adaptation to its specific habitat as it only occurs in the shadows of continually cool (without frost at night), wet, humid mist forests in Peru at 1300-3500 m; it also produces much wider leaves compared with its thickness (Hofreiter & Lyshede 2006).…”

Pollen morphology of 24 of the 33 species of three Bomarea subgenera, Baccata, Sphaerine, and Wichuraea, was examined by light microscopy (LM) and scanning electron microscopy (SEM), or SEM alone. The studied species of Bomarea were stenopalynous, characterized by large, monosulcate monads with reticulate exine sculpture in most species. Opercula-like structures were present on the sulcus in B. huanuco and B. involucrosa. Differences in pollen size, exine thickness, and exine sculpture were observed. The studied taxa were divided into four major groups based on exine ornamentation observed under SEM: microreticulate, reticulate, coarsely rugulate, or finely rugulate-perforate. Pollen characters alone did not appear to correlate clearly with the current subgeneric classification of Bomarea, but they may have some taxonomic utility below the subgeneric level. The most reliable infrageneric classification of Bomarea can be achieved through combined analyses of morphological, palynological, and molecular data from larger samples of specimens of all the species.

“…4). Comparison of the presence of a foliar indument with altitudinal distribution does not reveal any pattern, as has been suggested for other foliar characters such as epidermal platelets, margin type (involute/revolute) and leaf shape (Hofreiter & Lyshede, 2006).…”

Doing so will ultimately improve the estimate of phylogeny for the genus and will greatly assist in clarifying the taxonomy of the genus.…”

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.

Alstroemerieae is an exclusively Central and South American tribe belonging to Alstroemeriaceae, which comprises two large genera, Alstroemeria and Bomarea. Alstroemeria has two areas of distribution, mediterranean Chile and central southeastern Brazil. Most Bomarea species grow in forests and hedges in moist areas, however, some species are adapted to dry Andean valleys and high altitudes. Previous leaf anatomical data were obtained from a limited group of species. To assess the value of the anatomical characters for the systematics and their importance as adaptations to diff erent environments, we compared representative species from diff erent geographical areas and habitats. Data regarding leaf anatomy and micromorphology were obtained from light microscopy and scanning electron microscopy and were combined with macromorphology for 27 Alstroemerieae species. In accordance with earlier studies, our results show variation in relation to several leaf morpho-anatomical characters. Based on these we defi ne seven types. We furthermore analyzed the morpho-anatomical characters in a phylogenetic context. Morpho-anatomical characters are highly homoplastic within the family. Leaf anatomy may support monophyly of Baker ´ s informal grouping of Alstroemeria Brazilian species with rigid leaves, however, a more thorough study of Brazilian Alstroemeria species are needed to confi rm this.
