Annotation:

BackgroundEpidendreae is one of the most diverse tribes among the orchids with remarkable variation in life form, floral morphology and pollination syndromes. Its circumscription was recently revised and subtribes Agrostophyllinae and Calypsoinae were transferred into this tribe. One of the principal floral characters utilized in classification of orchids is the incumbency or bending of the column. This study records and compares late stages of anther, column and lip development, and discusses anther characters in fifteen representative taxa of five of the six subtribes in Epidendreae with respect to classification and pollination biology.MethodsA series of late floral stages were sampled and fixed for examination under scanning electron microscope.ResultsAnther incumbency or bending in this group varies from 90° to almost 180°. Incumbency in the late stages of development is reached in Bletiinae, Ponerinae, Pleurothallidinae and Laeliinae whereas incumbency is reached early in its development inCorallorhizaandGoveniaof Calypsoinae.DiscussionOur observations indicate that the position ofChysisin subtribe Bletiinae needs revision based on differences in a number floral, and in particular of anther characters; and thatCoeliaonly shares the early anther incumbency with Calypsoinae members, but not the rest of floral and anther characters. Anatomical characters such as crystals around the actinocytic stomata on the anther cap and sugar crystals in Laeliinae; lack of rostellum in Bletiinae; coalescent anther with the column, lack of trichomes and papillae on lip keels, and underdeveloped rostellum inChysis; a mechanism by which the anther cap comes off (it is joined with the grooved lip by a claw) inIsochilusare all related to pollination syndromes and reproductive biology.

Annotation:

A taxonomic revision of the Brazilian species of Encyclia is presented, based on analysis of roughly 1,400 herbarium specimens, including types. Thirty-nine species and one variety are listed for Brazil; we indicate 101 synonyms, of which eight are newly proposed. Lectotypes are chosen for five names (E. chironii, E. dutrae, E. paraënsis, E. tripartita and Epidendrum capartianum), including accepted names and synonyms. Two names are indicated as invalid (E. randii var. rondoniensis and E. vazzoleri), one name as a nomen nudum (E. guesneliana) and another as superfluous (Epidendrum pabstii). The occurrence of E. auyantepuiensis and E. thienii is confirmed for Brazil, and new occurrences are documented of E. fimbriata in Minas Gerais (in addition to Bahia) and E. linearifolioides in Maranhão and possibly Paraná (in addition to Matto Grosso and Tocatins States and Bolivia and Paraguay). All species are described and illustrated, and distribution maps are included. For both varieties of E. patens, nomenclatural and taxonomic notes are provided.

Annotation:

Epidendrum, one of the three largest genera of Orchidaceae, exhibits significant horticultural and ornamental value and serves as an important research model in conservation, ecology, and evolutionary biology. Given the ambiguous identification of germplasm and complex evolutionary relationships within the genus, the complete plastome of this genus (including five species) were firstly sequenced and assembled to explore their characterizations. The plastomes exhibited a typical quadripartite structure. The lengths of the plastomes ranged from 147,902 bp to 150,986 bp, with a GC content of 37.16% to 37.33%. Gene annotation revealed the presence of 78–82 protein-coding genes, 38 tRNAs, and 8 rRNAs. A total of 25–38 long repeats and 130–149 SSRs were detected. Analysis of relative synonymous codon usage (RSCU) indicated that leucine (Leu) was the most and cysteine (Cys) was the least. The consistent and robust phylogenetic relationships of Epidendrum and its closely related taxa were established using a total of 43 plastid genomes from the tribe Epidendreae. The genus Epidendrum was supported as a monophyletic group and as a sister to Cattleya. Meanwhile, four mutational hotspots (trnCGCA–petN, trnDGUC–trnYGUA, trnSGCU–trnGUCC, and rpl32–trnLUAG) were identified for further phylogenetic studies. Our analysis demonstrates the promising utility of plastomes in inferring the phylogenetic relationships of Epidendrum.

Annotation:

A little-studied orchid genus, Claderia Hook.f., has until now contained just one or two species, Claderia viridiflora Hook.f. and its possible synonym, C. papuana Schltr. We describe a new species from Singapore, which differs from these Claderia in having small, cream-yellow flowers that are nodding and presented in a long, unbranched terminal inflorescence, mostly with two flowers open simultaneously. We name the new species Claderia leontocampus Niissalo. Plants of the new species have been collected or recorded in Sumatra, Peninsular Malaysia and possibly Peninsular Thailand. We carried out population genetics analyses to show distinction between the new species and Claderia viridiflora. The two species occur in the same habitat in Singapore. We used phylogenetic analyses to find out the phylogenetic position of Claderia within Orchidaceae; the genus is here considered to belong to subfamily Epidendroideae Kostel., tribe Epidendreae Lindl., subtribe Claderiinae Szlach. We publish the plastome and ITS sequences of Claderia viridiflora. Two names are lectotypified.

Annotation:

Las orquídeas Epidendroideae presentan el polen organizado en polinios con diferente grado de compactación; cada polinio puede contener hasta 4 millones de granos de polen. En este estudio se evaluó la viabilidad y la germinación in vitro del polen aglutinado en polinios. Se evaluó la calidad polínica de siete taxones en dos tribus utilizando métodos palinológicos ex vitro (tinción con acetocarmín glicerol al 2 %) y directos (germinación in vitro) en tres medios, M1, M2 y M3. La viabilidad con acetocarmín fue superior al 85 % en los siete taxones estudiados. El mayor porcentaje de germinación in vitro se obtuvo en Catasetum tabulare, con un 16 %; en el resto de taxones los valores oscilaron entre el 2 % y el 5 % a las 72 horas de observación. El medio M3 fue el más exitoso, con 18 y 20 % de germinación en los taxones estudiados. Aunque la viabilidad del polen es alta, presenta tasas muy bajas de germinación, probablemente por el alto grado de compactación y la ausencia de aperturas, lo que la hace lenta y poco efectiva en medios artificiales. Los resultados ratificaron que no todo el polen viable germina, y que existe un alto grado de especificidad y dependencia frente a las sustancias estimuladoras de la germinación del polen provenientes del estigma de las orquídeas, lo que hace necesario seguir profundizando en el análisis de la biología del polen de la subfamilia Epidendroideae para comprender un poco más sus procesos de multiplicación natural.

Annotation:

Danxiaorchis singchiana (Orchidaceae) is a leafless mycoheterotrophic orchid in the subfamily Epidendroideae. We sequenced the complete plastome of D. singchiana. The plastome has a reduced size of 87,931 bp, which includes a pair of inverted repeat (IR) regions of 13,762 bp each that are separated by a large single copy (LSC) region of 42,575 bp and a small single copy (SSC) region of 17,831 bp. When compared to its sister taxa, Cremastra appendiculata and Corallorhiza striata var. involuta, D. singchiana showed an inverted gene block in the LSC and SSC regions. A total of 61 genes were predicted, including 21 tRNA, 4 rRNA, and 36 protein-coding genes. While most of the housekeeping genes were still intact and seem to be protein-coding, only four photosynthesis-related genes appeared presumably intact. The majority of the presumably intact protein-coding genes seem to have undergone purifying selection (dN/dS < 1), and only the psaC gene was positively selected (dN/dS > 1) when compared to that in Cr. appendiculata. Phylogenetic analysis of 26 complete plastome sequences from 24 species of the tribe Epidendreae had revealed that D. singchiana diverged after Cr. appendiculata and is sister to the genus Corallorhiza with strong bootstrap support (100%).

<p><strong>Objective: </strong>Amarkand is a group of medicinal plants, of which tubers are regularly consumed by the tribal people in India as food and medicine. It has a strong background of regional ethnopharmacological and food uses. Thus it can be effectively utilized as a source of natural antioxidants. The present study, of fourteen <em>Eulophia</em> species which are predominantly considered as “Amarkand”, were focused for their antioxidant potential and polyphenolic content which facilitates the contribution of the traditional knowledge of plants from India.</p><p><strong>Methods: </strong>Radical scavenging activity, ferric reducing antioxidant power and anti-lipid peroxidation assay were used to evaluate the antioxidant potential. In addition, total phenols, flavonoid and proanthocynidins were estimated.</p><p><strong>Results: </strong>Results showed that all the studied amarkand species have promising antioxidant potential. <em>Eulophia epidendrea </em>(J. Koenig ex. Retz.) C. E. C. Fisch. (EE) and <em>Eulophia mannii</em> (Rchb. f.) Hook. f. (EM) had highest free radical scavenging potential among all. <em>Eulophia epidendrea </em>have highest ferric reducing potential which may be due to high flavonoid and proanthocyanidin content present<em>.</em></p><p><strong>Conclusion: </strong>The data clearly demonstrated that EE and EM may serve as a good natural antioxidant source against oxidative stress and related diseases.</p>

AbstractRecent phylogenomic analyses based on the maternally inherited plastid organelle have enlightened evolutionary relationships between the subfamilies of Orchidaceae and most of the tribes. However, uncertainty remains within several subtribes and genera for which phylogenetic relationships have not ever been tested in a phylogenomic context. To address these knowledge-gaps, we here provide the most extensively sampled analysis of the orchid family to date, based on 78 plastid coding genes representing 264 species, 117 genera, 18 tribes and 28 subtribes. Divergence times are also provided as inferred from strict and relaxed molecular clocks and birth–death tree models. Our taxon sampling includes 51 newly sequenced plastid genomes produced by a genome skimming approach. We focus our sampling efforts on previously unplaced clades within tribes Cymbidieae and Epidendreae. Our results confirmed phylogenetic relationships in Orchidaceae as recovered in previous studies, most of which were recovered with maximum support (209 of the 262 tree branches). We provide for the first time a clear phylogenetic placement for Codonorchideae within subfamily Orchidoideae, and Podochilieae and Collabieae within subfamily Epidendroideae. We also identify relationships that have been persistently problematic across multiple studies, regardless of the different details of sampling and genomic datasets used for phylogenetic reconstructions. Our study provides an expanded, robust temporal phylogenomic framework of the Orchidaceae that paves the way for biogeographical and macroevolutionary studies.

En febrero 12 de 2009, el mundo celebró el 200avo cumpleaños de Charles Darwin. Sus contribuciones al estudio de la evolución y los orígenes del hombre son bien conocidos, pero su investigación botánica no ha sido apreciada en su justa medida. Darwin publicó nueve libros diferentes que se enfocaron sobre plantas domesticadas, plantas insectívoras plantas trepadoras, y otros temas botánicos, pero el más notable es su estudio sobre las orquídeas, ya que fue el primer libro publicado después del Origen de las Especies (1859). El libro de Darwin, Sobre las estrategias por las cuales las orquídeas británicas y las introducidas son fertilizadas por insectos (Darwin, 1862), fue una visión a la sistemática de las orquídeas de zonas templadas y tropicales y de sus polinizadores. Los nueve capítulos tratan especies de Orchideae, Arethuseae, Neottieae, Vanilleae, Malaxideae, Epidendreae, Vandeae, Cymbidieae (especialmente Catasetum) y Cypripedioideae. Las flores de las orquídeas fueron descritas y estudiadas por Darwin con gran detalle, cuidadosos registros del comportamiento de los polinizadores fueron mantenidos, y una gran dosis de especulación fue agregada. Nuestra comprensión de la filogenia, polinización, fisiología, y toda la historia natural de estos grupos han avanzado tremendamente en los últimos 150 años. Pocas personas han notado que “el libro de las orquídeas”, se subtitula... “y sobre el Buen Efecto del Entrecruzamiento”. Fenómeno que fue de gran interés para Darwin y las orquídeas brindaron ejemplos concretos para substanciar su teoría. Aún en nuestros tiempos, el libro de “Orquídeas” de Darwin, continúa inspirando a los biólogos evolucionistas y ejemplifica el poder de la selección natural.

t may seem somehow out of line to present a new system of botanical databases in the context of a meeting on orchid conservation, for two main rea- sons. Even though botanists have been rather slow in upgrading to the use of electronic databases (with some early controversy regarding the desirability of the application of electronic data processing methods to taxonomic problems as a whole, see i.e. Shetler 1974), the dissemination of plant information via the web has grown steadily in recent years.
