 Kyushu; common. Korea, China, Ryukyus, and Bonins. 



15. PLEUROSPERMUM Hofim. 



O-kasa-mochi Zoku 



Perennials or biennials; stems often stout; leaves ternately pinnate, the ultimate segments incised or dentate, sometimes pin- 

 nately lobed; umbels compound, large, the rays numerous, the bracts and bractlets numerous, membranous or foliaceous, some- 

 times pinnately lobed; flowers white, rather large; calyx-teeth minute; petals obovate or cuneate with an incurved apex; stylo- 

 podium flat or convex, entire; fruit ovoid or globose, nearly orbicular in cross section, with a broad commissure, the carpels con- 

 vex and with subequal, acute, narrowly winged ribs, the vittae usually solitary (rarely 2) in the intervals, the outer pericarp 

 loosely connected with the inner, the carpophore bifid; seeds compressed dorsally, with a deep groove on the commissural side. 

 About 15 species in Eurasia, especially the Himalayas. 



1. Pleurospermum camtschaticum Hoffm. P. uralense
