[Performance autoethnography and qualitative research in Collective Health: methodological (mis)encounters].

Performance autoethnography is qualitative research methodology that aims to problematize resistances between the "self" (auto-) and the collective (ethno-) in the act of writing (-graphy). The article thus aims to discuss the theoretical and practical construction of performance autoethnography and its applicability as a qualitative research and analytical method in the field of Collective Health through a performance autoethnography writing. By problematizing the epistemic and ontological basis of performance autoethnography, pointing to possibilities for its development and inclusion in studies in the field of Collective Health, the article presents performance autoethnography as a strategy to expand the possibilities for social justice, democratization, and pluralisms in and from research practices.

Secretory cavities and volatiles of Myrrhinium atropurpureum Schott var. atropurpureum (Myrtaceae): an endemic species collected in the restingas of Rio de Janeiro, Brazil.

In this study, we investigated the leaf anatomy and the composition of volatiles in Myrrhinium atropurpureum var. atropurpureum endemic to Rio de Janeiro restingas. Particularly, leaf secretory structures were described using light microscopy, and histochemical tests were performed from fresh leaves to localize the secondary metabolites.
