LAMARE-PICUOT, N., French naturalist, born in Bayeux, France, about 1785; died after 1835. He established a pharmacy in Mauritius, but afterward returned to Paris, and subsequently travelled to the East Indies, where he made natural history collections that were bought for the British museum. In 1841 he travelled in North America, and returned to Paris with numerous specimens, including a plant that he proposed to introduce in France. It was called by the Indians "tipsina," and by botanists " Psoralea esculenta," and has taken the name of Picquotiane, after its importer. It had been known to botanists. Pursh, who first described it about 1815, called it the famous bread-root of the northwestern Indians, and a favorite name with the French voyagers was pomme de prairie. A disease was prevailing at this time in the potato, and Picquot proposed the root of this plant as a substitute. In 1847 Mr. Lamare-Picquot received from the minister of commerce 7,000 francs and the order to search in North America for nutritious plants. He arrived in New York on 24 January, and went to the west, traversing Indiana, Illinois, Michigan, Wisconsin, and the northern part of the Mississippi. He returned to Havre in 1848, with the plants "psoralea" and "apios," the latter of which had been already cultivated in Europe.
