obtuse and minutely pauci-suberose at tlie apex, green, but pale and mem- 

 branaceous on the margin, with 3 veins which are connected at the end, 

 about 3| mm. long. Petals nearly twice the length of the sepal, ellip- 

 tical, rounded- subretuse, shortly clawed. Stamens shorter than sepals ; 

 filament subulate, dilated towards the base, glabrous ; anther elliptical. 

 Ovary oblong, glabrous, about 12~ovuled ; style shorter than the ovary ; stigma 

 sub-bilobed. Silicle linear-oblong, often slightly curved, acute at the upper 

 end, compressed, glabrous, 5-8 mm. long, the lower ones shorter than the 

 gracile erect-patent pedicels, the style short, gracile, with a shortly bifid

 with erect-patent linear-subulate argute teeth, attaining about 1 cm. long, 

 the uppermost one sometimes linear and entire. Raceme 7-20-flowered, 

 longer or shorter than the stem ; rachis gracile, glabrous ; pedicels gracile, 

 erect-patent, glabrous. Flower about 7 mm. across, white. Sepals small,

 sepals; filament subulate, dilated towards the base; anther small, oblong- 

 elliptical. Ovary narrowly oblong, glabrous : style short, stout ; stigma 

 subcapitate, slightly 2-lobed. Silicle broadly linear or linear-oblong, 5-11 

 mm. long, compressed, glabrous, straight or curved or slightly twisted, often
