Feb. i9i3.] y. MAJB2N0— OBSERVATIONS OX THE FLORA OF JAPAN. 25 



terminal lobe largest, ovato-orbicular to oblong, obtuse, often 

 few-subrepand-crenate, about |— If cm. long, f — 11 mm. broad ; 

 lateral lobes small, diminished in size towards the base, few on 

 each side, patent, deltoid to narrowly oblong, acutish ; petiole 

 narrow, but more or less dilated and amplexicaul at base, thinly 

 ciliated with pale pilose simple hairs, shorter than the blade ; 

 canline leaves loosely and remotely alternate, erect-patent, petio- 

 late but sessile in the superior ones, oblanceolate and depressed- 

 few-crenate in the lower, but linear and entire in the upper, 

 obtuse at apex, narrowed at base, glabrous, about li- 4 cm. long 

 including the petiole, which is often very thinly ciliated with 

 patent simple pilose hairs. Raceme erect, peduncled, several- 

 to submany flowered ; rachis slender, glabrous, green. Flowers 

 pedicellate, small, about 7-10 mm. in diameter and in length, 

 white ; pedicels erect-patent, gracile, glabrous, green, about 6—7 

 mm. long in flower, but attaining about 11 mm. long and 

 usually arcuate upwards in fruit. Sepals 4, erect, glabrous, 

 oblong or narrowly oblong, obtuse or acutish at apex, entire, 

 concave internally, green, but scarious towards the margin, 

 about 3-3J mm. long, 1J mm. broad ; veins delicate, about 2-3 

 on each side of the rather stronger midrib, loosely anastomosing 

 with the vertical narrow areas. Petals 4, twice as long as 

 the sepals ; lamina spreading, obovato-orbicular with a broad 

 claw, which is suddenly attenuated to a cuneate form at the 

 base. Stamens longer than the sepals but the lateral shorter 2 

 often equal to them, the longer 4 about 4 mm. long ; filament 

 subulate, glabrous ; anther oblong-linear, nearly 1 mm. long. 

 Ovary longer than the stamens, erect, angustate, compressed, 

 glabrous, about 4J mm. long ; stigma subsessile ; ovules many, 

 minute, oblong. Silique erect-patent, angustato-linear, 



straight, much longer than the pedicel, attaining about 3 cm. 

 long, 1 mm. broad, viridescent, acutely short-attenuated and 

 with a subsessile stigma at the top ; valves thin, usually deli- 

 cately 2— nerved. Seeds numerous, minute, 2-serial often 

 blended into 1, elliptical, angustately pale-winged circularly, 

 with a filiform funicule, fulvous, about 1 mm. long.
