This is a species with a very similar appearance to Cortusa 
Mattioli. The leaf is longly stalked with thin petiole. The 
lamina is orbiculate reniform in outline, cordate at the base, and 
shallowly 5-9-lobed with broadly ovate and sharply denticulate 
lobes. The inflorescence is a single umbel, but in luxuriant 
specimens there is a second umbel superposed. The flower 
is of a deep crimson colour, but not particularly attractive. 
The plant is usually glabrescent, but sometimes more or less 
pubescent all over, and then is easily mistaken for the next 
species, when one runs down a key. While the calyx of P. kisoana 
is invariably thickly pubescent with long soft hairs, the calyx 
of P. jesoana is never lanate-pubescent. 
The systematic position of this species is undoubtedly very 
close to P. septemloba, Franch., a Yunnan species, and it belongs 
to the series of the Himalayan P. geraniifolia, Hook. f., and 
possibly of the Siberian P. Kaufmanniana, Regel. 
P. jesoana is found in woods in Yezo and in the mountainous 
districts of Central Japan. It is also distributed in the Korean 
Peninsula ? as well as the Island of Quelpart,? which is of great 
interest from the phytogeographical point of view.

One of the most beautiful, interesting, and rare of the 
Japanese Primulas. This species has a close relationship to the 
preceding. As characteristics this species has thick lanate in- 
dumentum, especially on the petiole, under surface of the lamina, 
scape, and even on the pedicel. The calyx densely hirsute is 
the character which distinguishes this from the foregoing species. 
The leaf has the lamina smaller than in the other species, with 
obtuse denticulation, and petiole thicker and more fleshy. This 
species, P. kisoana, Miq., is probably to be placed near P. mollis, 
Nutt., a Himalayan plant. 
This species is found in S.W. Japan, but only rarely. ae
