“…Clade V supports the monophyly of the group V. corcovadensis , which was revised (Gomes‐da‐Silva and Costa, ) and shown to be polyphyletic in a cladistic analysis with a reduced taxonomic sampling of Vriesea compared with this analysis, and based only on morphological data (Gomes‐da‐Silva et al., ). On the other hand, this group was recovered as monophyletic in a morphological analysis of the genus by Costa et al.…”

“…Among the about 280 spp. described in the genus Vriesea until 2012 (Gomes‐da‐Silva et al., ), 42 taxa (39 species and three varieties) of xeric habit that were placed in this genus based only by presenting with a petal appendage were transferred by Grant (, , , ) and Butcher () to Tillandsia . Based on the results of total evidence analysis performed for Vriesea , we can verify the absence of a phylogenetic and morphological relationship and disjunct (Fig.…”

“…Phylogenetic analyses in Tillandsioideae have focused on overall relationships within the subfamily (Terry et al, 1997;Horres et al, 2000;Crayn et al, 2004;Barfuss et al, 2005Barfuss et al, , 2016 or within individual genera (Chew et al, 2010;Gomes-da-Silva et al, 2012;Versieux et al, 2012;Costa et al, 2015). Based on molecular data, the subfamily has been divided into four lineages, treated as tribes: Catopsideae, Glomeropitcairnieae, Vrieseeae and Tillandsieae (Barfuss et al, 2005(Barfuss et al, , 2016; two new subtribes, Cipuropsidinae and Vrieseinae, have been described within the tribe Vrieseea (Barfuss et al, 2016).…”

The taxonomic delimitation of Vriesea is challenging because several diagnostic traits of the genus are shared with other genera in Tillandsioideae. The genus has no unique morphological features that distinguish it from other taxa. Earlier phylogenetic studies suggested a polyphyletic status of this genus, but taxon sampling was limited, and tests of congruence for morphological characters have not yet been performed. Here we used a total evidence approach and a more comprehensive Brazilian taxon sampling to help circumscribe Vriesea s.s. (the lineage that contains the type species). We concatenated morphological and molecular datasets for the first time to reconstruct phylogenetic hypotheses. We used 99 morphological characters and ~4 kb of plastid data (psbA‐trnH, trnK5′‐rps16, matK, trnL‐trnF) for 172 terminals, including nine genera of Tillandsioideae. We analysed datasets by parsimony analyses, with several weighting schemes considered for character‐state changes (equal weights and an implied weighting scheme that we used as a sensitivity analysis). The concatenated data resulted in a well‐resolved phylogenetic inference that provided strong evidence that the genus is not monophyletic as traditionally circumscribed. Given the congruence between morphological, molecular and geographical sources of data, we separated Vriesea into distinct lineages, and proposed a new circumscription that includes only species of Vriesea s.s. found in the Chacoan and Parana subregions.

“…Even though some morphological characters have been shown to be homoplastic (HornungLeoni & Sosa 2008;Almeida et al 2009;Gomesda-Silva et al 2012;Schulte et al 2009;Donadío et al 2014), many of them continue to be extremely important in the delimitation of taxonomic groups in Bromeliaceae (Hornung-Leoni & Sosa 2008;Almeida et al 2009;Gomes-da-Silva et al 2012), in contrast to the lack of molecular divergence in traditional analyzed fragments of DNA (Clark & Clegg 1990;Horres et al 2000;Schulte et al 2005;Faria et al 2004;Versieux 2009). Although intensive efforts have been made to search for new and informative DNA fragments together with the use of microsatellites (Versieux et al 2012) and amplified fragment length polymorphism (AFLP; Rex et al 2007;Louzada 2012), detailed studies of morphology are also necessary in order to reveal traits of evolution that might not appear in molecular phylogenies, and important for identifying morphological synapomorphies (Assis 2009).…”

Morphological Phylogenetic Analysis of Two Early-Diverging Genera of Bromelioideae (Bromeliaceae)

2015

Bromelia includes 66 species, grouped in three subgenera: Bromelia, Distiacanthus and Karatas. The genus is one of the earlier divergent groups within Bromelioideae, a subfamily with innumerable problems of generic delimitation. Considering that few phylogenetic studies have included more than one species of Bromelia, the objectives of this study were to carry out a phylogenetic analysis for the genus, seeking to evaluate its monophyly as well as its subgenera, and to better understand the interspecific evolutionary relationships within the genus and the intergeneric relationships within Bromelioideae. Also included in the analysis were the two species of Fernseea, a genus originally described from a species placed in Bromelia. The phylogenetic analysis was conducted with combined micro-and macromorphological data, including 39 taxa with 116 characters. As in other studies on Bromeliaceae, the clades have low statistical support and many questions regarding the relationships of the groups remain. The circumscription of Bromelia is still uncertain, due to the position of B. irwinii; Fernseea seems to emerge within this genus, as the marority-rule consensus suggests, and the infrageneric categories are debatable because they do not constitute monophyletic groups. However, Bromelia seems to be paraphyletic and, without B. irwinii, the genus can be considered monophyletic. Beginning with the premise that the most recent common ancestor of Bromelioideae appeared first in the southern Andes, Bromelia and Fernseea seems to have dispersed along three biogeographical routes. The present work is an important contribution to understand the evolution and biogeography of the Bromelioideae.

“…Morphometric methods can be instrumental in discovering, documenting and analyzing morphological character and character states, and have become important tools for understanding similarities and inferring relationships in different groups of plants. Morphometric and cladistic analyses based on morphological characters have been carried out in a number of genera and families (Michelangeli 2000, Roalson et al 2002, Li and Conran 2003, Sonibare et al 2004, Gomes-da-Silva et al 2012). …”

Phenetic analysis based on morphological characters is presented for 14 species of Desmodium Desv. in Bangladesh. This study examines patterns of morphological similarity and variation within Desmodium using 36 floral and vegetative characters. D. heterophyllum shows highest similarity with D. triflorum among the species employed. UPGMA dendrogram is constructed based on cluster analysis which reveals two major clusters, the first of which consists of seven species while the second cluster comprises six species, and D. microphyllum is found far from all other species. The presence of winged petioles distinguishes D. alatum and D. auriculatum from the other species. The present study shows the application of morphometric analysis for understanding the phenetic relationships among the species of Desmodium.
