 Mag., Tokyo, VI. 1892, p. 52. 



Rhizome very short, erect or oblique, rooting. Leaves tufted, flaccid, 

 reniform or reniform-orbicnlar, cordate at the base, 5-1 6| cm. across, thin 

 when dried, scattered with pilose hairs on the upper surface and ciliated on 

 the margin, deeply divided into 7 to sub-11 broad-ovate to oblong-ovate lobes 

 with obtuse sinuses ; lobes paucilobulate ; lobules incisely dentate with ovato- 

 deltoid and mucronate teeth ; veins palmate ; petiole slender, 6-25 cm. long, 

 villose- pilose with spreading hairs, vaginate and ciliated with long rufo-hairs 

 at the base. Scape erect, pilose, usually bearing 1-3 small rudimentary 

 ciliated leaves ; panicle loose, narrowly pyramidal ; rachis slender, more or 

 less flexuous, furnished with small linear bracts fimbriato-ciliated below, 

 glandular-hairy as are the peduncles and pedicels, which are filiform and 

 bear linear-subulate bracteoles ; the peduncles usually secund. Calyx 5- 

 partite, the tube adherent, to the base of ovary; sepals patent or reflexed, 

 more or less unequal in size, oblong-lanceolate or ovato-lanceolate, obtuse or 

 acute, entire, ciliated and disparse with glandular hairs, 3-nerved. Petals 

 5, white, thin ; the lower 2 much larger, pendulous, equal in size, narrowly 

 spathuiate-lanceolate, acuminate, gradually narrowed towards the base and 

 at length forming a filiform unguis, entire, about 2-2J cm, long, 2J-4J mm. 

 broad, with a few loosely arranged nerves which run upwards ; the upper 

 3 patent, about 4 mm. long, ovate, acutish or obtuse, distinctly unguiculate, 

 with a few yellow spots, loosely few-nerved. Stamens 10, spreading, longer 

 than the sepals ; filament filiform, acute at the apex, gradually narrowed 

 below; anther ovato-rounded, orange-coloured. Ovary broadly ovate, shortly 

 divided into 2 above and gradually attenuated to the styles, yellowish green, 

 with a yellow disk- shaped nectar placed across on its upper surface ; styles 

 2, slender, beaklike ; stigma thicker ; ovules numerous, minute, oblong. 

 Capsule with persistent sepals, styles, withering petals, and filaments, rounded- 

 ovate, inflated, 2-divided above ; carpel thin ; seeds numerous, subcylindrical- 

 oblong, minutely papillose, brown.

Hob, Prov. Tosa : Nanokawa (T. Makino ! Nov. 1884, Nov. 5, 1887 ; 

 K. Watanabel Sept. 30, 1891), Takaoka-gori (Y. Yoshinag.al), Beppu- 

 mura (T. Maldno ! Nov. 1892) ; Prov. Ise : Yuwochi-mura in Iidaka-gori (Z. 

 Umemural Oct. 13, 1895); Prov. Idzumi: Mt. Inunaki-san (S. MatmdaX

The 3-nerved sepals, ovate upper petals, equal-sized lower petals, 

 and the more flaccid and more deeply lobed leaves should be taken as the 

 principal characters to separate this from Saxifraga coriuso?folia Sieb. et 

 Zucc.
