THE WALNUT. 239 



As these Japanese and Chinese walnuts are natives 

 of cold climates they may be better adapted to the North- 

 ern than Southern States, but there is no locality en- 

 tirely exempt from late spring frosts, as most farmers 

 and fruit growers learned to their cost the past season. 

 There can be little doubt of this species of walnut being 

 the one described by Rhumphius under the name of J. 

 Camirium, and more fully later by Loureiro, as already 

 noted ; but having come to us from Japan as Siebold's 

 walnut, this name will answer as well as any other, even 

 if it is not the proper one. 



JUGLASTS CORDIFORMIS, Maxim. In foliage and 

 growth of tree this is almost, if not absolutely, identical 

 with the last ; the difference observed 

 is in the nuts, which are also pro- 

 duced in pendulous clusters. The 

 form of the nut is almost round 

 (Fig. 86), rather blunt-pointed, but 

 the shell is deeply and unevenly fur- 

 rowed, and indented somewhat like 

 our black walnut ; the ridges, how- 

 ever, are not as sharp. The speci- 

 mens I have received from various FIG 86 JUGIjANS 

 sources are not as large as the Sie- CORDIFORMIS. 

 bold, and the shell not quite as thick, but the kernel is 

 small. I may note here that there appears to be some 

 confusion in regard to this variety or species, for in sev- 

 eral nurserymen's catalogues this form of nut is figured 

 as Siebold's, and the one that I have described under 

 that name is called Cordiformis. The specimens re- 

 ceived from California, Japan, and also from Mr. Berck- 

 mans, correspond with the names here given, but further 

 investigations may show that they should be reversed. 

 The one I have received as Cordiformis is, doubtless, 

 the nut described by Loureiro as J. Catappa, as an 

 ovate-oblong nut, with a fibrous, leathery, reddish husk.
