is always easily distinguished by the glabrous angular shoots and the 

 perfectly plane and smooth upper surface of the leaves. 



Young plants of P. koreana raised from cuttings brought by Mr. 

 Wilson from Korea, are growing in this Arboretum and are very hand- 

 some with their large bright green leaves marked with a conspicuous 

 red midrib and nearly white on the under side. 



BIBLIOGRAPHICAL NOTES

Nouveau Duhamel. Upon the publication of my note on "Nouveau 

 Duhamel" in this Journal vol. ii, no. 3, I received a letter from Miss 

 Alice Atwood of the Bibliographical staff of the Department of Agri- 

 culture at Washington, calling attention to references which had escaped 

 my notice, which seem to prove that the work appeared in 83 livraisons 

 instead of in 80 as stated by me, and that volume i was published from 

 1800 to 1801. To quote in part from this letter: "An article by Bouchard- 

 Huzard 'Note bibliographique sur le Traite des arbres et arbustes et sur 

 le Traite des arbres fruitiers, par Duhamel du Monceau' in the Journal 

 de la Societe imperiale et centrale d J horticulture de France, v. 12, 1866, 

 states on pages 472-473 that the work appeared in 83 livraisons (1800- 

 1819). Konigand Sims' Annals of botany, vol. i. no. 1, p. 69 in the 'Retro- 

 spect of botanical literature for 1801-03' speaks of the new edition of 

 Duhamel's Traite, begun in 1800." From these references and others 

 since discovered it seems clear the "Nouveau Duhamel" was issued in 

 83 livraisons from 1800 to 1819. I gladly take the opportunity to make this 

 correction. 



Mouillefert. Traite des arbres & arbrisseaux. From a bibliographical 



point of view it is always of interest to know the form in which a work 



i 



originally appeared; if in parts, coming out at more or less irregular in- 

 tervals during a number of years, when those parts were issued, how many 

 pages they contained, whether there were covers, and whether those covers 

 gave dates, w T hich unfortunately they often do not. In the case of botanical 

 works it is of great importance as involving questions of priority, and it 

 is quite deplorable that in the majority of cases when such volumes are 

 bound the covers are destroyed and valuable information lost altogether 

 or recovered at the expenditure of much painstaking labor and time. 

 Mouillefert 's "Traite des arbres & arbrisseaux forestiers, industriels et 

 d'ornement cultives ou exploites en Europe et plus particulierement en 

 France donnant la description et l'utilization de plus de 2400 especes et 

 2000 varietes," issued in 38 parts, is bound in 3 vols., without covers.
