HOWARD. ENUMERATIO & SELECTARUM THE ENUMERATIO AND SELECTARUM OF NICOLAUS VON JACQUIN RICHARD A. HOWARD IN HIS INTRODUCTIONS to the facsimile editions of Jacquin's EnumcratioSystematica Plantarum, 1760 (Sertum Botanicum V, 1967) and SelectarumStirpium Americanarum Historia, 1763 (Hafner Publ. 1971), FransStafleu has supplied biographical and bibliographical information on Nic-olaus Jacquin, and on these two important early volumes which concernthe nomenclature of many common plants of the Caribbean area. Stafleuemphasizes that the two volumes must be studied together, for the Enu-meratio is to be regarded as a "Prodromus" to the Selectarum in whichmany of the species are given more ample descriptions and localities oforigin or are illustrated. All too often in modern botanical work theplace of publication of Jacquin's names is given as the Selectarum withthe date 1763, when the correct citation is the Enumeratio published in1760. A survey of the two volumes, with emphasis on the taxa men-tioned in the Enumeratio, reveals that many of the binomials are not inuse today either for accepted species, or as basionyms or synonyms. Forothers, Jacquin illegitimately substituted a new name in the Selectarumor reduced his own name to the synonymy of an earlier published name ofLinnaeus, Loefling, Guettard, or Miller. In this paper I have attempted to give modern equivalents of all of thenames used in Jacquin's Enumeratio, including corrected citations whennecessary. Although many of the plants described are common in theCaribbean area, only a very few names can be typified by association withspecimens collected by Jacquin. Some names can be typified by an illus-tration in the Selectarum. Hopefully this listing will lead monographersand curators to search for additional holotype specimens rather than todesignate neotypes as many are doing. Jacquin was a student of medicine in Vienna in 1752. Stafleu relatesthat during this period "Jacquin's botanical interests remained alive, cer-tainly also because of the rich collections in the imperial gardens at Schoen-brunn. Franz I of Austria, who took great interest in botany, and es-pecially in his garden, became acquainted with Jacquin and consideredhim the right man to send on a collecting trip to the West Indies. Jacquinwas to collect plants and animals for the Schoenbrunn garden and for theHof-Naturalien-Cabinet. The plants were to be mainly living plants . . "The party of which Jacquin was a member arrived in Martinique on June28, 1755, and during a four-year stay visited St. Vincent, Grenada, Curacao,Aruba, Venezuela, and Colombia to the south, and Guadeloupe, St. Kitts,St. Eustatius, St. Maarten, St. Barthelemy, "Domingo" (being Haiti andthe Dominican Republic) and Cuba, before leaving in January, 1759, for1973]
