TAKEDA—JAPANESE PRIMULAS. gi 
This variety is characterised by sharp, shallow denticulation 
on the margin of the leaf. All other essential points agree well 
with those of the typical form of the species, so that it seems 
to me to be more natural to regard this as a variety. 
The plant is found in the Alpine pastures on high mountains 
of Central and Northern Japan.

A luxuriant form of P. cuneifolia. The leaf is slightly thinner 
than that of the preceding variety, and has very obtuse, large 
teeth, which are often provided with denticulation. 
This variety is found on high mountains of Northern Hont6.

Another Japanese species with fleshy leaf. This is, however, 
easily distinguished from the other species of the same group 
by its smaller leaf with few simple, obtuse teeth, and corolla 
not exceeding 10 mm., white with yellow eye. 
This is not uncommon on certain high mountains in Northern 
Hont6, growing in the Alpine pasture in abundance. It has been 
recorded nowhere outside Japan. 
EXCLUDED SPECIES. 
In the foregoing pages I have discussed all the recorded Japanese 
Primulas with the exception of the following four species :— 
P. nivalis, Pall., P. prolifera, Wall., P. sibirica, Jacq., and P. 
veronicoides, Petitm. 
anc and Decrock! record the occurrence of the first three 
in Japan. They do not, however, give any evidence or reference 
to publications, so that it is difficult to see what source their 
statements have been derived from. At the present moment 
I can only discard these species from the flora of Japan until 
sufficient evidence confirms their being indigenous.
