I have seen no Japanese specimens of M. fiorihunda, nor has Mr. Wilson col- 

 lected it or seen it in Japan. The Japanese botanists apparently do not know it; 

 the plant they enumerate under the name M. florihunda is M. Halliana, as part 

 of their synonjony, their descriptions and specimens named by Japanese botanists 

 show. All we know of this plant is the fact that it was introduced by Siebold from 

 Japan. It may possibly be a hybrid of M. haccata and M. Sieholdiij as Zabel sug- 

 gests; according to Wenzig it represents P. kaido X haccata and Schneider men- 

 tions as possible parentage M. prunifolia X M. toringo.

 Wilson (No. 6660; bush 1.3-2 m., branches spreading, flowers white) ; same locality, 

 alt. 600-1000 m., May 7, 1914, E. U. Wilson (No. 6659; tree 8 m. tall, branches 

 erect, flowers white); Lake Chuzenji, margin of woods, alt. 1200-1500 m., June 3, 

 1914, E. H, Wilson (No. 6797; tree 3-12 m. tall, 0.3-0.6 m. girth, branches erect- 

 spreading, flowers white) ; same locality, August 10, 1905, /. G. Jack; Nikko, prov. 

 Shimotsuke, 1879 and May 1889 (ex Herb. Tokyo, co-type), same locahty, June 

 1899, H. Shirasawa, September 1903, T. Makino. 



The specimens from Lake Chuzenji and Wilson's No. 6659 from Gotemba and 

 Shirasawa's and Makino's specimens from Nikko differ from the type speci- 

 men in their broader sharply serrate leaves, but apparently they cannot be referred 

 to any other species but M. zumi. They resemble in general appearance M. haccata, 

 var. mandshurica, but differ in the condiiplicate vernation of the leaves and in the 

 number of styles which is usually 4, but sometimes 5 and less often 3 — among 

 15 flowers of No. 6797 I found 8 with four styles, 4 with five styles and 3 with 3 

 styles — while in M. haccata, var. mandshurica the number of styles is 5. From 

 M. Sieholdii to which M. zumi is also closely related, it is distinguished by the
