UNLIKE her neighbouring country China, Japan possesses com- 
paratively few species of this genus. However, more than half 
of the indigenous species are endemic. Since the publication of 
Thunberg’s Flora Japonica! not a few botanists have directed 
their attention to Japanese Primulas in their floristic and system- 
atic works.2 In Professor Matsumura’s Index Plantarum 
Japonicarum, vol. ii, pt. ii, published in r1g1t2, the following 
16 species are enumerated as natives of Japan :—
