“…The subfamily Epidendroideae include approximately 650 genera and 18 000 species and represent a greater number of genera and species than the other four subfamilies combined (Pridgeon et al, ; Freudenstein & Chase, ), and they are classified into 16 tribes and 28 subtribes (Chase et al, ). Numerous DNA phylogenetic studies have now been published for this subfamily, including studies covering the subfamilies, tribes, subtribes, and genera.…”

“…The completion of the FRPS, Flora of China , and the updated taxa of orchids have contributed greatly to the understanding of Chinese orchid classification and diversification. Although molecular phylogenetic studies in the past 30 years have greatly improved our understanding of the classification systems (e.g., Chase et al, , 2015) and evolution (e.g., Freudenstein & Chase, ; Givnish et al, ) of the whole orchid family, the Chinese orchids have never been rigorously tested using molecular data.…”

We estimated the molecular phylogenetic relationships of the Chinese members of the family Orchidaceae. Within the Tree of Life for the Genera of Chinese Vascular Plants using atpB, rbcL, matK, ndhF, and matR, the currently delimited subfamilies, tribes, and subtribes are highly supported as monophyletic except for the perplexing Epidendroideae. Five genes (rbcL, matK, psaB, ycf1, and Xdh), which are more universally used in Orchidaceae, were further analyzed to reconstruct the phylogeny of Epidendroideae. The reconstructed trees were in strong agreement and showed significant support for the tribal and subtribal clades. Based on the highly supported circumscription and arrangement of the suprageneric levels in the Tree of Life and reconstructed trees, we have proposed a new phylogenetic classification of Chinese Orchidaceae that includes five subfamilies, 17 tribes, and 21 subtribes.

“…DNA sequencing -The genus Tropidia and Corymborkis are recognizable within the Tropidieae tribe, among the other early-branching Epidendroideae (Freudenstein & Chase 2015). According to the BLASTn tool, our nrITS sequence (KR604798), with 588 base pairs (bp), presented 99.3% identity with another sequence of T. polystachya (EU490674.1) deposited in the GenBank database of the NCBI; matK plastid sequence (KR604800), with 897 bp, presented 99% identity with T. graminea (EF079304.1); and rbcL plastid sequence (KR604799), with 561 bp, presented 100% identity with Tropidia sp.…”

“…On the other hand, molecular analyses, of the rbcL plastid gene, positioned Tropidia as part of an unresolved grade that is sister of most other Epidendroideae (Cameron et al 1999). A recent phylogenetic study on the subfamily based on mitocondrial, nuclear and plastid regions combined (Freudenstein & Chase 2015) placed Tropidia as sister to Corymborkis Thouars, with strong support, among the other earlybranching epidendroids.…”

-(First record of the genus Tropidia Lindl. (Orchidaceae) for Brazil). The genus Tropidia is composed of ca. 20-30 species distributed in southern Asia, South Pacific islands and northern Australia, and a single species occurring in America, from United States to Ecuador. The first record of the genus Tropidia for Brazil is presented here. It consists of Tropidia polystachya, a species found in the Cerrado biome, Midwestern Brazil. Description, illustration, photos, and distribution map of the species are provided. Additionally, the leaf anatomy of the species was studied and it is very similar to the leaves of other species of Tropidieae described so far. DNA sequences of T. polystachya are presented (plastid matK and rbcL and nuclear ITS) in order to assist future phylogenetic studies with the genus.

ResumenEl género Catasetum posee distribución neotropical con centro de diversidad en la Amazonía Brasileña. Colombia es uno de los países más ricos en orquideoflora, sin embargo, también muy poco explorado. El objetivo de la presente investigación fue conocer la diversidad, distribución, conservación y especies con potencial uso en cultivo comercial de Catasetum para Santander y Colombia. Se registran 14 especies y un nuevo reporte para Colombia, C. tenebrosum. Estas han experimentado un proceso de cultivo y domesticación para la preservación y propagación del material con el propósito del manejo de colecciones privadas y comercialización. La distribución y riqueza inter específica se encuentra principalmente en los municipios asociados al Valle interandino del Magdalena medio, al igual que la modelación de nicho ecológico sumando la Cordillera Oriental flanco Occidental en la región del Piedemonte, entre un rango altitudinal de 50 a 1000 m.s.n.m. Se amplía la distribución y rango altitudinal de C. lucis, especie exclusiva de Santander y en este estudio no se encontraron poblaciones nativas de C. tricorne. En conclusión, Santander posee la mayor diversidad de Catasetum para Colombia, por lo que puede ser considerado centro de conservación in situ y ex situ de las especies del país.

Phylogenetic relationships in Epidendroideae (Orchidaceae), one of the great flowering plant radiations: progressive specialization and diversification

Abstract: All tested characters show significant association with speciation in Epidendroideae, suggesting that no single character accounts for the success of this group. Rather, it appears that a succession of key features appeared that have contributed to diversification, sometimes in parallel.
