Jiiglans sulcata^ by Wildenow, in his Berlinische Baumzucht, p. 

 154, together with several of the other species previously known. 



In 1803, Michaux (Flor. Bor. Amen, ii., 192) divided Jug- 

 lafis into two sections, the one containing the real walnuts, the 

 other the hickories, but he did not give them even sub-generic 

 names, and described no species additional to those previously 

 recorded. 



The younger Michaux's Histoire des Arbres Forestiers de 

 TAmerique Septentrionale (1810), brought in Juglans myristiccE- 

 formtSj the Nutmeg Hickory, and Juglans aqicaticay the Water 

 Hickory. 



We have now reached the time of Rafinesque, and his state- 

 ment, given at the head of this article, is the first separation of 

 the Hickories from the Walnuts, under a distinct name. Unfor- 

 tunately the proof of his paper in the Medical Repository was 

 not well read, and Scoria was printed for Hicoria. There need 

 be no doubt of what was intended. Rafinesque says in his Flo- 

 rula Ludoviciana (18 1 7), p. 109, '* My name, Hicoriits, long ago 

 proposed, contains all the species of Juglans, which have trifid 

 male flowers (instead of six-cleft), generally tetrandrous, and 

 fruits with angular and quadrifid shells." He then characterizes 

 two species, both of which were already known. 



The next important phase in the history of the genus was the 

 introduction of the generic name Carya^ by Thomas Nuttall, in 

 his Genera of North American Plants, published in 1818. Quite 

 ignoring Rafinesque, he publishes the genus as containing species 

 of Juglans of Linnaeus and WiUdenow, gives a list of nine spe- 

 cies without their equivalents and with descriptions of three only, 

 yet, inasmuch as many of his specimens are preserved, he is gen- 

 erally cited as author of the binomials. This injustice did not 

 pass without a protest on the part of Rafinesque, for in the very 

 next year he remarks as follows, in ''Journal de Physique," &c., 

 p. 260 (Vol. Ixxxix., 1819): '' Hicorws, Raf Obs. Fl. Ludov., 

 1817, a ete change sans cause en Carya, N., nom posterieur radi- 

 cal et tres-mauvais." It is remarkable that he does not here re- 

 fer to his publication in the Medical Repository nine years be- 

 fore. But the next statement that Rafinesque made, regarding 

 the genus (Alsographia Americana, 1838, p. 65), makes evident 

 what he had then intended. He says under the caption :
