Juglans sieboldiana. Maxim. (J.ailantifolia, Carr.). Figs. 2014-2016. Broad-headed tree, to 50 ft.: branchlets pubescent: lfts. 11-17, oval to oval-oblong, short- acuminate, densely serrate, glabrous above, pubescent and usually glandular beneath, 3-6 in. long: frs. in long racemes, sometimes 20, globose to ovate-oblong; nut more or less globose, with thick, wing-like sutures and pointed apex, the surface rather smooth, slightly rugose and pitted, 1-1 1/2in. long, rather thick-shelled. Japan. Gn. 47, p. 442. A.G. 1890:701; 1891:179. R.H. 1878, pp. 414, 415. U.S.N.C. 7, p. 7. S.I.F. 2:5. var.cordiformis, Makino (J.cordiformis, Maxim.). Fig. 2017. Nut heart-shaped or ovoid, much flattened, sharply 2-edged, smooth and with a shallow longitudinal groove in the middle of the flat sides, rather thin-shelled. G.C. III. 30:292. S.I.F. 1:17. U.S.N.C. 7, p. 6.裕hough this form is very different in its fr. from the true J. sieboldiana there are no other reliable characters to distinguish it, and seedlings raised from nuts of var. cordiformis have always produced, at least to a large percentage, trees bearing nuts like those of J. Sieboldiana or of intermediate character. Probably J. Lavallei, Dode (L.I. 1, 2), is such an intermediate form. J. coarctola, Dode, is another of these intermediate forms with a somewhat longer nut slightly constricted about the middle. J. subcordiformis, Dode, is hardly different from the variety except in its shorter and broader nuts. J.Allardiona, Dode, is probably only a form of the species; it differs little from it except in the gray or blackish dull color of the nut, which is yellowish and lustrous in typical J. Sieboldiana.
