CONSERVATION AND TYPIFICATION OF DALEA

when the author citation is abbreviated to one name, his is the important one to retain. (Durand's is the one name omitted by Beal [loc. cit.], who gives "Engelm. ex Clinton".) This situation has bearing on the type. Beal designates as lectotype a specimen from Detroit, collected by Bigelow in 1865. The original description, however, clearly refers to a specimen from New York, in the Academy of Natural Sciences of Philadelphia, ex herb. H. H. Eaton, ex herb. Short. This specimen would be the type, if extant (a point on which Beal sheds no light). There is no evidence that Durand saw the Bigelow specimen, which is in the Gray Herbarium and is accompanied by a letter from Engelmann to Gray; if it is not ,,original material", it is not eligible to be designated as lectotype, even if a lectotype were needed. However, there is a specimen of this species in the Academy of Natural Sciences, collected in New York in 1828, from the herbarium of H. H. Eaton, bearing also a label of the Academy indicating that it was in the C. W. Short Herbarium, presented in 1864. There are no further data, but the sheet (consisting of two leaves, a complete flower, and a dissected flower) is certainly the type of Nuphar variegatum Durand."' Engelmann recognized, at least at times, that this was a new species, and he suggested a name for it. But the important fact from the standpoint of nomenclature is that he was not the first to publish a description (in fact, at the time of the first published description he was said to doubt the validity of the species). The epithet variegatum is often dated from the 5th edition of Gray's Manual (1867), where it is attributed to Engelmann, as a variety of N. advena.7 Had a description by Durand, citing only a New York specimen, not been published the year before, the citation would be ,,Engelmann ex Gray." Careful application of Article 46 validates Durand, whose description is quoted by Clinton, as the publishing author and makes clear the designation of a New York specimen as type.
