After a second visit to Montevideo, their next opportunity to collect plants was in Patagonia while the ships of the expedition were waiting for favourable winds to carry them through the Strait of Magellan. Here Baret accompanied Commerson on the most troublesome excursions over rugged terrain and gained a reputation for courage and strength. Commerson, still hampered by his leg injury, referred to Baret as his "beast of burden" on these expeditions. In addition to the manual labor she performed in collecting plants, stones, and shells, Baret also helped Commerson organize and catalog their specimens and notes in the weeks that followed, as the ships entered the Pacific.
