Orchids : intersex and identity in documentary

Orchids: Intersex and Identity in Documentary explores the creative practice challenges of working with bodies with intersex in the long-form auto/biographical documentary Orchids. Just as creative practice research challenges the dominant hegemony of quantitative and qualitative research, so does my creative work position itself as a nuanced piece, pushing the boundaries of traditional cultural studies theories, documentary film practice and creative practice method, through its distinctive distillation and celebration of a new form of discursive rupturing, the intersex voice.

Orchids, intersex and the auto/biographical project

Auto/biographical documentaries ask audiences to take a ‘leap of faith’, not being able to offer any real ‘proof’ of the people and events they claim to document, other than that of the film-maker’s saying this is what happened. With only memory and history seen through the distorting lens of time, ‘the authenticity of experience functions as a receding horizon of truth in which memory and testimony are articulated as modes of salvage’. Orchids: My Intersex Adventure follows a salvaging of the film-maker’s life events and experiences, being born with an intersex condition, and, via the filming and editing process, revolving around the core question: who am I? From this transformative creative documentary practice evolves a new way of embodying experience and ‘seeing’, playfully dubbed here as the ‘intersex gaze’.

Orchids : My Intersex Adventure

Orchids: My Intersex Adventure is a multi-award winning autobiographical documentary film. The film follows documentary filmmaker, Phoebe Hart, as she comes clean on her journey of self-discovery to embrace her future and reconcile the past shame and family secrecy surrounding her intersex condition. Despite her mother’s outright refusal to be in the film, Phoebe decides she must push on with her quest to resolve her life story and connect with other intersex people on camera. With the help of her sister Bonnie and support from her partner James, she hits the open road and reflects on her youth. Phoebe’s happy and carefree childhood came to an abrupt end at puberty when she was told she would never menstruate nor have children. But the reasons why were never discussed and the topic was taboo. At the age of 17, Phoebe’s mother felt she was old enough to understand the true nature of her body and the family secret was finally revealed. Phoebe then faced an orchidectomy, invasive surgery to remove her undescended testes, the emotional scars of which are still raw today. Phoebe’s road trip around Australia exposes her to the stories of other intersex people and holds a mirror to her own experience. She learns valuable lessons in resilience and healing but also sees the pervasive impact her condition has on all her relationships. At home, Phoebe and James want to start a family but dealing with infertility and the stress of the adoption process puts pressure on their marriage. Phoebe also starts to understand the difficult decisions her parents faced and is excited but apprehensive when they eventually agree to be interviewed. Will talking openly with her mother give Phoebe the answers she has been looking for? The film was produced and directed by Phoebe Hart and commissioned by the Australian Broadcasting Commission. The film premiered at the Brisbane International Film Festival in 2010 where it was voted the number one film of the festival by audiences. Orchids was broadcast on ABC1 in Australia in 2012, appeared in more than 50 film festivals internationally and has since been broadcast nationally in Switzerland, Sweden, Israel, Spain, France, Russia, Poland, Germany and the USA.

Making orchids – Gardening an intersex experience on videotape [In German - Orchideen Züchten. Eine inter Erfahrung auf Film]

In 2004, my thirtieth year of life, I began to develop and produce a documentary about the lived experience of being intersex. At the time, I didn’t ever expect the film would be autobiographical in nature. I’d known I was intersex since I was 17, and aware of my difference for many years prior, and I’d been making and presenting documentaries for almost as long, yet the idea to expose myself so publicly was frightening to me. However, I realised I couldn’t expect others to step in front of the lens when I didn’t have the courage to do so myself. The final result was Orchids: My Intersex Adventure, which maps my intersex journey from shame, stigma and secrecy to self‐acceptance. The film has now been broadcast on television sets around the world. It has also won many awards and appeared in numerous film festivals....

Phyllosticta species on orchids (Orchidaceae), introducing Phyllosticta speewahensis sp. nov. (Phyllostictaceae, Ascomycota) from northern Australia

Several species of Phyllosticta (syn. Guignardia) have been described from orchids worldwide. A new species, Phyllosticta speewahensis, is proposed for a specimen isolated from leaf spots on a hybrid Vanda orchid in northern Queensland, Australia. Phylogenetic analysis of the nrDNA internal transcribed spacer region (ITS) and partial translation elongation factor 1-alpha (TEF1) gene sequences showed that P. speewahensis is most closely related to P. hostae. The likelihood that orchids harbour further cryptic species of endophytic and pathogenic Phyllosticta species is discussed.

Studies on the microbial diseases of dendrobium hybrid (orchids)

There is no baseline data available at present on the nature of various diseases that occur in a orchid population, under cultivation, in any commercial orchid farm maintained by small scale entrepreneurs who invest considerable amount of money, effort and time. The available data on type of disease symptoms, causative agent, , nature of pathogens, as to bacteria or ftmgi or any other biological agents, and their source, appropriate and effective control measures could not be devised, for large scale implementation and effective management, although arbitrary methods are being practiced by very few farms. Further influence of seasonal variations and environmental factors on disease outbreak is also not scientifically documented and statistically verified as to their authenticity. In this context, the primary objective of the present study was to create a data bank on the following aspects 1. Occurrence of different disease symptoms in Dendrobium hybrid over a period of one year covering all seasons 2. Variations in the environmental parameters at the orchid farms 3. Variations in the characteristics of water used for irrigation in the selected orchid farm 4. Microbial population associated with the various disease symptoms 5. Isolation and identification of bacteria isolated from diseased plants 6. Statistical treatment of the quantitative data and evolving statistical model

Convergent evolution of floral signals underlies the success of Neotropical orchids

The great majority of plant species in the tropics require animals to achieve pollination, but the exact role of floral signals in attraction of animal pollinators is often debated. Many plants provide a floral reward to attract a guild of pollinators, and it has been proposed that floral signals of non-rewarding species may converge on those of rewarding species to exploit the relationship of the latter with their pollinators. In the orchid family (Orchidaceae), pollination is almost universally animal-mediated, but a third of species provide no floral reward, which suggests that deceptive pollination mechanisms are prevalent. Here, we examine floral colour and shape convergence in Neotropical plant communities, focusing on certain food-deceptive Oncidiinae orchids (e.g. Trichocentrum ascendens and Oncidium nebulosum) and rewarding species of Malpighiaceae. We show that the species from these two distantly related families are often more similar in floral colour and shape than expected by chance and propose that a system of multifarious floral mimicry—a form of Batesian mimicry that involves multiple models and is more complex than a simple one model–one mimic system—operates in these orchids. The same mimetic pollination system has evolved at least 14 times within the species-rich Oncidiinae throughout the Neotropics. These results help explain the extraordinary diversification of Neotropical orchids and highlight the complexity of plant–animal interactions.

Hybridization and introgression across different ploidy levels in the Neotropical orchids Epidendrum fulgens and E-puniceoluteum (Orchidaceae)

The hypothesis of gene flow between species with large differences in chromosome numbers has rarely been tested in the wild, mainly because species of different ploidy are commonly assumed to be reproductively isolated from each other because of instantaneous and strong postzygotic barriers. In this study, a broad-scale survey of molecular variation was carried out between two orchid species with different ploidy levels: Epidendrum fulgens (2n = 2x = 24 chromosomes) and Epidendrum puniceoluteum (2n = 4x = 52 chromosomes). To test the strength of their reproductive barriers, we investigated the distribution of genetic variation in sympatric and allopatric populations of these two species and conducted crossing experiments. Nuclear and plastid microsatellite loci were used to genotype 463 individuals from eight populations across the geographical range of both species along the Brazilian coastal plain. All six sympatric populations analysed presented hybrid zones, indicating that hybridization between E. fulgens and E. puniceoluteum is a common phenomenon. Bayesian assignment analysis detected the presence of F(1) and F(2) individuals and also signs of introgression, demonstrating a high potential for interspecific gene flow. Introgression occurs preferentially from E. fulgens to E. puniceoluteum. Pure parental individuals of both species display strong genotype-habitat associations, indicating that environment-dependent selection could be acting in all hybrid zones. This study suggests that hybridization and introgression are evolutionary processes playing a role in the diversification of Epidendrum and indicates the importance of investigations of hybrid zones in understanding reproductive barriers and speciation processes in Neotropical orchid species.

Gibberellic acid and water regime in the flowering induction of Brassocattleya and Cattleya hybrid orchids

No presente trabalho foi avaliada a influência do ácido giberélico e do regime hídrico na indução e qualidade do florescimento de duas orquídeas híbridas dos gêneros Cattleya (C.) e Brassocattleya (Bc.). O experimento foi realizado no Setor de Biotecnologia e Orquidicultura da Fundação Shunji Nishimura de Tecnologia, Pompéia-SP. Foram testadas cinco concentrações de GA3 (0, 125, 250, 500 e 1.000 mg L-1) em quatro aplicações consecutivas via pulverização foliar, em plantas adultas que já haviam florescido ao menos uma vez, além de duas condições hídricas (uma e quatro irrigações por semana). As aplicações foram feitas nos meses de outubro e novembro para Bc. Marcella Koss e janeiro e fevereiro para C. Irene Holguin. Não foi possível induzir a floração em Cattleya Irene Holguin com o uso de ácido giberélico. Para Bc. Marcella Koss, a aplicação de 250 mg L-1 de GA3, associado à diminuição na frequência de irrigação, induziu cerca de 83% das plantas ao florescimento. Na mesma concentração de GA3, porém em condições de irrigação frequente, apenas 17% das plantas foram induzidas a florescer. O número e o tamanho das flores aumentaram com a aplicação de concentrações maiores de GA3 utilizadas no experimento. A realização deste trabalho permitiu desenvolver uma técnica comercial com o uso de ácido giberélico (GA3) para a indução do florescimento do híbrido de orquídea Bc. Marcella Koss.
