 filaments abruptly dilated and obtusely bidentate at base; capsule ovoid-

 oblong, with a very few hairs; stamens and pistil about equal to the pet- 

 als; filaments not toothed; capsule ovoid-acute, about as long as the calyx,

 to a foot high, glabrate, repeatedly dichotomous ; leaves oblong, obtuse or

 der, spreading, as much as 35 mm. long, many times exceeding the minute 

 yellow flowers ; sepals narrow, acute, very sparingly glandular-ciliate ; 

 petals obovate-oblong, constricted toward the base, more or less emar- 

 ginate, 1-2 mm. long, scarcely exceeding the calyx, 3-appcndiculate, the 

 median appendage oblong, glabrous; stamens and pistil a little shorter
