1 " Ob fiores revera terminales, bracteolas lineari-lanceolatas scariosas et folia acuta." Dr. 

 Maximowicz (in " Mel. Biolog. Diagn." decas 12) refers this to V. Oxycoccus, instead of to V. 

 macrocarpum,, which is " semper bene distinctum floribus axillaribus, bracteolis ovatis foliaceis 

 et foliis obtusis." But in one of my specimens the axis of the umbel is continued into a leafy 

 shoot, as in V. macrocarpum ; and the bracteolae vary from linear to ovate, and from thin 

 and scarious to chartaceous or coriaceous in both species ; they are never (so far as I know) 

 " foliaceous " in V. macrocarpum, but the bracteae sometimes are. The leaves are some- 

 times acutish in the latter, and also very obtuse in V. Oxycoccus ; in the Japanese specimens 

 under consideration they are often half an inch in length. I must add that in the length of 

 the filaments they accord with the character which I assigned to V. Oxycoccus in the Manual. 

 In fact, a form combining the characters of the two species survives in Japan.
