Illustrations: 4 text-figures by Yamada (1. c. p. 307) are given, 

 showing telia on juniper branch, cross section on the swollen stem, 

 teliospores and germination of teliospores. 



Notes: The finding of aecia on Pyrus spectabilis by Shirai in 

 Tokyo was reported by Dietel as ? Gymno sporangium claviaef orme 

 Jacq. (in Hedwigia 37: 216. July, 1898) and by P. Sydow as 

 Gymno sporangium ? clavariiforme (Jacq.) Rees (do. Beibl. 37*: 

 (207) Nov -Dec, 1898). P. Hennings listed an aeeium on Pyrus 

 Toringo collected by Shirai at Nikko as ? G. clavariiforme (Jacq.) 

 Rees (in Engler's Bot. Jahrb. 28: 262. Mar., 1900), and he later 

 reported G. clavariiforme from Tokyo, found by Hori on P. spec- 

 tabilis (do. 31 4 " 5 : 732. Aug., 1902). These are all likely to 

 represent G. Yamadae. Under G. Yamadae Miyabe sp. nov., 

 Kern presented a description of the aecial stage found on Pyrus 

 spectabilis by Nambu at Tokyo (in Bull. N. Y. Bot. Gard. 7 26 : 

 466. Oct., 1911), and Sydow later described the telial stage under 

 the same name from material presented by M. Miura (in Ann. 

 Mycol. 12: 159-160. Apr., 1914). Ito (in Byochu-gai Zasshi, 

 Journ. PI. Prot. 4 4 : 244-245. Apr., 1917) ventured, however, to 

 bring this name into the synonymy with G. chinensis Long (in 

 Journ. Agr. Res. 1 : 345. Jan., 1914) but all later investigators 

 have considered the latter to be identical to G. asiaticum (= G\ 

 haraeanum = G. koreaensis). See Clinton, in Ann. Rept. Conn.. 

 Agr. Exp. Stat, for 1914 p. 15, 16. 1914; Jackson, in Journ. Agr.. 

 Res. 5: 1006. Feb., 1916 and Kern in Mem. N. Y. Bot. Gard. 6 : 

 247-249. Aug., 1916.
