 The scientific collections are held by the Royal Botanical Garden of Madrid (about 7100 herbarium sheets with 200 genera and 3500 new species of plants).The great impact that the results of the expedition had on the botanical community has been documented by the botanical scholar Rogers McVaugh, an expert on the Flora of Mexico.The paintings remained in the possession of Mociño, who accompanied Sessé to Spain after the expedition, but they appeared lost after his death in 1820 in Barcelona, where he settled after living in France and Switzerland during periods of political upheaval in Spain.
