TAKEDA—JAPANESE PRIMULAS. 89 
the leaf, which is generally spathulate, and abruptly attenuated 
into a narrowly winged petiole, and is usually revolute and slightly 
or hardly denticulate on the margin. The length of capsule is, 
as in the typical form of the species, variable, so that no stress 
can be laid on this character at all. 
This variety is widely distributed over Yezo and the Kurile 
Islands, and is usually found on cliffs near the sea. It has, 
however, been recorded from Honté, as growing on Mt. Iwate, 
Province of Rikuchu.

This is perhaps the smallest species of all the Japanese Primulas. 
It comes near to the preceding species, but is easily distinguished 
by its much smaller size and efarinose character. As was pointed 
out by Professor Miyabe,! this species also does not belong 
to Pax’s Macrocarpae. At first glance it appears to be identical 
with P. mistassinica, Michx., of North America, differing however 
in the far less and very slightly saccate bracts and nearly orbicu- 
late-spathulate leaf, which is thinner in texture, sharply denticulate, 
and abruptly tapers into the petiole. The flower has been 
described as white with yellow eye by both Maximowicz and Pax. 
This is not correct. The _—_ is rose-coloured with yellow 
eye, as in the foregoing spec 
Pax regards P. mpponica, Yatabe, as identical with P. macro- 
carpa, Maxim., but this is a mistake. His description? of P. 
macrocarpa is a chimera of P. macrocarpa, Maxim., and P. 
nipponica, Yatabe 
The present species is one of the rarest, and is found only on 
Mt. Hayachine, Province of Rikuchu.

This is probably the best known species of the Japanese 
Primulas in Europe, so that I need not describe it in detail.
