ly attenuated below and loosely ciliated on margin towards the base, entire, 

 rounded or subretuso-rounded at the apex, 14-16 mm. long, 6-5 mm. wide, 

 7-nerved, thinly membranaceous between nerves; nerves parallel and elevated 

 on the inner surface, fasciculately ramose into tine veinlets above. Stamens 

 10, shorter than petals and about |-§ as long as them, about 10 mm. 

 long, the oppositisepalous ones slightly longer ; filaments very shortly con- 

 nate at the base, compressed, white, the oppositisepalous ones eubulato- 

 filiform glabrous and thick at the base, the oppositipetalous ones subulate 

 and thinly pilose below ; anther elliptieo-oblong, or oblong, bifid at both 

 ends, pale (extremely light yellow) with same-coloured pollen, li-f mm. 

 long. Ovary ovoid-oblong, glabrous, yellowish-viridescent, 2-2| mm. long, 

 carpel thin and 10-nerved ; styles 5, erect, filiform, glabrous, white, equalling 

 the stames in height, about 61 mm. long ; stigma obliquely internal ; ovules 

 many, erect-patent, obovoid. Capsule cylindrical, scarcely curved upwards 

 above, much exserted, 2|-3-times as long as the persistent calyx, 11-17 mm. 

 long, membranaceous, smooth, simply 10-uerved ; the mouth truncate, 10- 

 tenclate ; the teeth circinato-revolute when dry, not revolute on margins, 

 elliptico-ovate or ovato-oblong, obtuse. Seeds subnumerous, about 20 or a 

 little more in number, obovoid-oval, slightly compressed, tuberculate all 

 over, bay, 1 mm. long. 



Nom. Jap. Tagasode-so. 



Hab. Prov. Shinano : Yamato-mura in Mimami-Adzumi-gori (D.

Largest one among Japanese species of Cerastimn. It is remarkable 

 by having the entire (not bifid) petals. The flower has a resemblance to 

 that of some species of Oxalis.
