On April 25 Grigadale Arboretum in Argentina received a small group of visitors for its first Oak Day. Participants came from near and far (from Buenos Aires at 500 km, and even from Salta in the north of Argentina, almost 2,000 km away) and included IOS members Peter Laharrague and Marilyn Mulville, members of the International Dendrology Society, a researcher from a leading botanic garden, and other oak enthusiasts—or soon to be enthusiasts.

Some large acorns from Portugal lead to interesting correspondence with Iberian oak expert Francisco Vázquez.

I recently had the opportunity of seeing one of the largest pedunculate oaks (Quercus robur) in South America. It stands at the edge of the large lawn in front of the homestead at La Porteña al Sur, once part of a vast estancia (estate) with a rich history stretching back to arrival of the Spaniards in the region of what is now Buenos Aires. The tree is remarkable for the size it has attained in a relatively short time, but also for its habit.

IOS-member Teodoro Marañón has sent me links to a special issue of the Spanish journal "Ecosistemas" (Ecosystems) that he has co-edited.
