TL;DR: The name Calanthe grandiflora was published by Nadeaud (1873) for a plant first discovered in the Papenoo Valley, Tahiti, French Polynesia and is now also known from Raiatea, Tahaa, Huahine and Moorea were I saw it for myself.
Abstract: The name Calanthe grandiflora was published by Nadeaud (1873) for a plant first discovered in the Papenoo Valley, Tahiti, French Polynesia. The species is now also known from Raiatea, Tahaa, Huahine and Moorea were I saw it for myself. The name was transferred to the genus Phaius Lour. by Schlechter (1926) who published the nomen novum Phaius tahitensis. Unfortunately he did not give any indication why he thought it necessary to create a nomen novum rather than a new combination. I can only speculate that he saw the entry under the genus Phaius in Index Kewensis which reads \"P. grandiflorus Rchb. f. in Walp. Ann. vi. 459\". More recently Margońska & Szlachetko (2010) cited this as \"Phaius grandiflorus (Nadeaud) Rchb.f., Walp. Ann. 6: 459. 1861, nom. illeg. non Phaius grandifolius Lour., Bot. Reg. 25, Misc.: 40. 1839\". This immediately aroused my suspicion as the epithets \"grandiflorus\" and \"grandifolius\" are not normally considered homonyms. When checking the Reichenbach reference, it turns out that this is definitely not a new combination of the Nadeaud name. Reichenbach writes \"Phajus grandiflorus Lour. B. Reg. XXV. 1839. Misc. 40.\" When I tried to check the reference he cites (Cunningham, 1839), I noticed two typing errors. First, the name and quoted text is found on page 34 and not page 40. More importantly, Cunningham gives the name as \"P. grandifolius Lour.\", referring to a name published earlier by Loureiro. The Cunningham reference can therefore at most be interpreted as a misapplied name. From all this, I must conclude that the name Phaius grandiflorus Rchb.f. is invalid firstly as the name is not accepted by the authors (Art. 34.1), not by Reichenbach who merely quotes the text under Phaius australis and not by Cunningham who's text is quoted as he equates it with Phaius tankervilleae (Banks) Blume; secondly, \"grandiflorus\" is merely a typing error for \"grandifolius\" (Art. 61.1). The inevitable conclusion must be that the name Phaius tahitensis is an illegitimate superfluous name as the epithet \"grandiflorus\" should have been used as it was available at the time. To correct this I validate here the combination.

TL;DR: Maximum parsimony and Bayesian inference analyses were performed based on nucleotide sequences of the nuclear internal transcribed spacer and cpDNA genes of 88 taxa representing the major clades of the Calanthe alliance in China and indicated that Cephalantheropsis is monophyletic, while both Phaius andCalanthe are polyphyletic.

TL;DR: The yellow perianth and sweet floral scent of P. delavayi are important cues in attracting pollinators, while flowering time and mass population are associated with the process of “learning and avoidance” of the rewardless flowers.
Abstract: The genus Phaius is distributed mainly in pantropical areas, and most species reported are autogamous. In contrast, Phaius delavayi, an alpine plant endemic to temperate zones of China, is strictly pollinator dependent. Only female workers and males of the bumblebee species B. hypnorum and B. lepidus are effective pollinators. The pollinaria are deposited on top of the head or the prothorax of the pollinators. The different depositions of pollinaria are regarded as an adaptation of the chamber dimensions of the flower to the size of the pollinator. The natural fruit set reported here (24.6–37.1%) suggests that pollination is successful in the deceptive P. delavayi. The yellow perianth and sweet floral scent of P. delavayi are important cues in attracting pollinators, while flowering time and mass population are associated with the process of “learning and avoidance” of the rewardless flowers. This orchid, therefore, employs a deceptive pollination strategy with diverse pollinators and pollinaria depositions rather than autogamy as do its congeners.

TL;DR: The following nine new additions to the orchid flora of Laos PDR are reported based on surveys in the country conducted during the period 2012-2017: Bulbophyllum alcicorne, B. meson, Coelogyne suaveolens, Cyrtosia nana, Dendrobium phuketense, Oberonia rhizoides, Phaius columnaris, Thelasis khasiana and Zeuxine longilabris.
Abstract: The following nine new additions to the orchid flora of Laos PDR are reported based on surveys in the country conducted during the period 2012-2017: Bulbophyllum alcicorne, B. meson, Coelogyne suaveolens, Cyrtosia nana, Dendrobium phuketense, Oberonia rhizoides, Phaius columnaris, Thelasis khasiana and Zeuxine longilabris. The taxonomy of a further 15 orchid taxa (Bulbophyllum guttulatum, B. moniliforme, B. sarcophyllum, B. scabratum, B. seidenfadenii, B. tipula, Cleisostoma lecongkietii, Coelogyne ovalis, Dendrobium chapaense, D. crepidatum, D. wattii, Habenaria gibsonii var. foetida, H. malintana, Luisia zeylanica and Phalaenopsis pulcherrima) native to Laos or adjacent countries is reviewed, resulting in the synonymisation of 20 names. In addition, new combinations are made for Grosourdya vietnamica, Luisia sonii and Holcoglossum gaoligongense to bring them in line with recent changes in the classification of the orchid family.

TL;DR: Results of present study suggests crossability and compatibility between these two species which helped in synthesize novel hybrid species and an attempt to develop a new Phaius species by using two native species viz., PhaiUS tankervilleae (Banks ex l’Heritier) Bl and Phaiu flavus (Blume) Lindl.
Abstract: Popularly known nun orchid or swamp orchid (Phaius sps.) is listed as endangered species under Schedule-I of Indian Wild Life (Protection) Act, 1972. Natural Phaius hybrids were not reported and present study is an attempt to develop a new Phaius species by using two native species viz., Phaius tankervilleae (Banks ex l’Heritier) Bl and Phaius flavus (Blume) Lindl. Result of present study suggests crossability and compatibility between these two species which helped in synthesize novel hybrid species. New Phaius hybrid produced flowers with dominating yellow-orange colour (RHS 17B/A) sepals and petals are bright crimson colour (RHS 175B) with elongated stripes on lip inside. First flowering of Phaius cross progenies (PBX-11-22) was observed in Jan-Mar, 2017 with regular flowering habit in consecutive seasons. Comparison with parents indicated distinct nature in floral attributes. Unlike Phaius flavus, the sepals and petals of novel progenies have spreading nature. Flower size varies from 7-8 x 8.5-9 cm with mild fragrance on shiny and warm days. Sequential flowering in acropetal fashion with 8-10 florets observed on moderately strong spike with potted vase life > 40 days. * Corresponding author
