Morphological and habitat similarities among the five species of the terrestrial orchid genus Calopogon have led to nomenclatural and taxonomic confusion. The taxa are marked by subtle character differences and little apparent reproductive isolation. Here we investigate allozyme diversity at the species level and the partitioning of genetic variation within and among species and their populatio...

We report the first occurrence of Encyclia gonzalezii L.C. Menezes (Orchidaceae) from state Maranhão and Northeast Region Brazil. The species was collected in Cerrado domain Estreito, Maranhão. present a map collection site, morphological description, photographs, ecological comments, provisional conservation assessment, an identification key for

This study was contacted on Orchidaceae, it is a second largest family in flowering plants, comes after Asteraceae, and approximately has 25,000–30,000 species 750–800 genera the world. included 10 genera, Anacamptis (five species), Androrchis (two Cephalanthera (one Dactylorhiza (three Epipactis Himantoglossum Limodorum Neotinea Ophrys (seven ), Orchis (four species). The name abbreviation of ...

A new species of Encyclia from Mexico, Encyclia inopinata, is described and illustrated. This species is similar to Encyclia diota but it can be distinguished by its usually more robust plants with 2-3 leaves per pseudobulb and its flowers with longer and narrower sepals (1.8±0.1 × 0.63±0.03 cm in Encyclia inopinata versus 1.48 ±0.14 × 0.65±0.06 cm in Encyclia diota) and petals (1.7±0.05 × 0.59...

A 3,000 m2 area of seasonally inundated forest on the island of Ilha do Mel (25 degrees 30" S 48 degrees 23" W) in Paraná, Brazil, was sampled by collecting plants from all strata, using climbing equipment when necessary. The area harbors 103 species of epiphytes, in 49 genera and 20 families, of which 28 species are pteridophytes and 75 magnoliophytes (64 Liliopsida, 11 Magnoliopsida). The mos...

Amarkand tubers are routinely consumed by Indian tribes as food and medicine. Some species from genus Eulophia (Orchidaceae) and Dioscorea bulbifera L. (Dioscoraceae) are referred as Amarkand. Their different local names and location specific availability lead to ambiguity in identification and incorrect selection of a particular species as medicine. Present study is focused to find out their p...

Coelogyne putaoensis, a new species of section Ocellatae from Putao, Kachin State, Myanmar, is described and illustrated. It is morphologically similar to C. taronensis and C. weixiensis, presumably its nearest relatives. An identification key and colour photographs are provided. A preliminary risk-of-extinction assessment according to the IUCN Red List categories and criteria is given for the ...

Spiranthes himalayensis is described here as a new species based primarily on molecular phylogenetic evidence followed by morphological comparison with other Asian Spiranthes species. It is distributed widely from southern India to tropical China. Phylogenetic analysis shows its close affinity to S. nivea which is endemic to Taiwan. Morphologically, the new species looks close to S. sinensis an...

BACKGROUND Stelis (Orchidaceae) encompasses approximately 1100 species of epiphytic orchids distributed throughout the Neotropics, with the highest diversity in Andean South America. Sixty-two species were recorded previously in Mexico. METHODS We formally describe here Stelis zootrophionoides as a new species from Chiapas, Mexico. To determine its systematic position, we conducted a morpholo...

Dendrobium huoshanense (Orchidaceae) is a perennial herb and a widely used medicinal plant in Traditional Chinese medicine (TCM) endemic to Huoshan County town in Anhui province in Southeast China. A microsatellite-enriched genomic DNA library of D. huoshanense was developed and screened to identify marker loci. Eleven polymorphic loci were isolated and analyzed by screening 25 individuals coll...
