|One of the major morphological characteristics found in many (but not all) acanths are the "explosively dehiscent capsule" method of seed dispersal.|
August 2011: Erin Tripp and Lucinda McDade, together with co-authors Siti Fatimah and Iain Darbyshire, submit manuscript on the interlineage hybrid, heteroplasmic genus Physacanthus.
August 2011: Erin Tripp and evolutionary ecologist Kyle Dexter return to Namibia for further study of the Acanth flora and the evolution of the regionally endemic, species-rich genus Petalidum; they are joined by Namibian student Hendrina Hasheela.July 2011: Siti Fatimah and Erin Tripp submit manuscript on comparative anatomy and morphology of the African genus Satanocrater for peer review.
July 2011: Siti Fatimah is accepted into a graduate program in the Netherlands (University of Leiden), where she is to pursue research in ecology and evolutionary biology. She finishes her employment at RSABG in August 2011 - Siti, we will miss you! Long live Acanths of Malaysia!
July 2011: Siti Fatimah, Ryan Stanfield, Erin Tripp, and Lucinda McDade present results from their research on Ruellieae at the 2011 Botany Conference in St. Louis, MO. Erin Tripp is awarded the annual Cooley Award for the best paper presented in Plant Systematics for her work on the intergeneric, interlineage hybrid Physacanthus (in collaboration with Lucinda McDade, Siti Fatimah, and Iain Darbyshire).
Jun 2011: Master's student Dan Koenemann and Erin Tripp submit manuscript on the nomenclature of Sanchezia for peer review.
May 2011: We have been working on the evolutionarily complex genus Physacanthus for nearly two years now. Results have been recently synthesized, and the manuscript is on its way for peer review. Physacanthus is heteroplasmic, having chloroplasts of two different Acanth lineages within a single plant. Morphology of the genus also suggests it may be an intergeneric, interlineage hybrid.
March 2011: Tripp travels to China for a month to collect Acanthaceae with Chinese colleague and Acanth specialist Dr. Deng Yunfei. The fieldwork was a success - with almost all targeted genera found in flower or fruit in Yunnan, Hunan, Guizhou, and Guangdong Provinces.
December 2010: Dan Koeneman, PhD student in botany at RSABG, completes a successful semester-long RA ship with Tripp & McDade; Dan undertook two projects: 1) a complete bibliographic investigation of all names ever published in Ruellieae (2,265!), and 2) a nomenclatural study of the taxonomically difficult genus Sanchezia. Results from both projects will be tremendously helpful to our Systematics of Ruellieae manuscript, which is in prep.
October 2010: Tripp, together with Kew Gardens colleague Dr. Iain Darbyshire, discover a new species of Barleria among the recent field collections of E. Tripp and K. Dexter from Namibia. The manuscript is in preparation.
September 9th 2010: Ryan Stanfield is awarded a $10,400 fellowship to support his upcoming master's research on the ability of cystoliths to sequester heavy metals.

August 6th 2010: Ethiopian botanist Ensermu Kelbessa and grad student Mekbib Fekadu arrive at RSABG for a month of training and collaborative research. Ensermu, Tripp and McDade survey pollen diversity of all genera in Ruellieae; Mekbib participates in a 10-day molecular systematics training workshop, then conducts a comparative survey of leaf and stem anatomy across Ruellieae. Some anatomical sections can be seen here.

January - February 2010: Tripp and McDade travel to Europe to study natural history collections and make contact with colleagues. The following herbaria were visited: Z (Switzerland), GZU, W, WU (Austria), M, B (Germany), C (Denmark), S, UPS (Sweden), BR (Belgium), K, HNN (United Kingdom). Several Acanthaceae specialists were consulted during these travels including Dr. Alexander Schmidt-Lebuhn (Z), Dr. Mariette Manktelow (UPS), Dr. Kaj Vollesen (K), and Dr. Iain Darbyshire (K).
January 2010: Siti Fatimah Binti, (then) undergraduate at California State Polytechnic University - Pomona, hired to help in the molecular lab and to assist with other aspects of the research project.
