Commerson suffered badly from both seasickness and a recurring ulcer on his leg in the early part of the voyage, and Baret probably spent most of her time attending to him. Aside from the ceremony of "crossing the line", which Commerson described in some detail in his memoir, there was little for the botanists to do until the "Étoile" reached Montevideo. There they set out on expeditions to the surrounding plains and mountains. Commerson's leg was still troubling him, and Baret seems to have done much of the actual labor, carrying supplies and specimens. In Rio de Janeiro – a much more dangerous place, where the "Étoile"s chaplain was murdered ashore soon after their arrival – Commerson was officially confined to the ship while his leg healed, but he and Baret nonetheless collected specimens of a flowering vine, which he named "Bougainvillea".
